Alpha-lipoic Acid––the "Ideal Antioxidant"

The antioxidant potential of a substance is based on a number of criteria, including:
1) Ability to quench specific free-radicals.
2) Ability to bind or "chelate" metal ions that can generate free radicals.
3) Supports function of other antioxidants.
4) Absorption/bioavailability.
5) Concentration in tissues, cells and extra cellular fluids.
6) Ability to function as an antioxidant in fatty and watery environments.

The "ideal antioxidant" would meet all the above criteria. Very few antioxidants do, yet a particular antioxidant with but a few of the characteristics is still valuable and effective. Vitamin E, for example, is one of the most important dietary antioxidants, yet it only works in fatty environments such as cell membranes.

As a team, ALA and DHLA come close to the ideal, for the following reasons:1,2,3
1) ALA is easily absorbed when consumed orally.
2) ALA is readily converted to DHLA in various tissues.
3) As a pair, ALA and DHLA neutralize Superoxide, hydroxyl, peroxyl, and hypochlorus radicals.
4) ALA and DHLA form stable complexes with metal ions such as iron, manganese, copper and zinc ions.
5) ALA and DHLA scavenge free radicals in fatty environments and watery environments.
6) DHLA recycles other important antioxidants.

DHLA-regenerates vitamin C, vitamin E and glutathione

Within the cell, antioxidants work as a team to keep free radicals from damaging cell structures. In order to neutralize a free radical, an antioxidant such as vitamin C must give up an electron, which mean it becomes oxidized. Before it can function as an antioxidant once again, it must be regenerated back to its "reduced" form, by gaining an electron to replace the donated electron. For this, it needs the help of other antioxidants. Vitamin C, vitamin E and glutathione are key antioxidants that can be generated by cycling between their oxidized and reduce forms. This is necessary to maintain the balance between oxidation and its reverse––the neutralization of free radicals by antioxidants.

DHLA is an essential component in the interaction between these antioxidants.4 Studies show that addition of alpha-lipoic acid to liver tissues results in increased vitamin C levels. It has been found that DHLA is responsible for regenerating vitamin C, which in turn regenerates vitamin E.3 DHLA also converts glutathione from its oxidized form back into its free radical scavenging reduced form.3,5 The ALA/DHLA pair is thus vital for prevention of "oxidative stress," which occurs which the balance is tipped in favor of oxidation in cells.4 DHLA helps preserve antioxidants in both the watery cell interior and the fatty structure of cell membranes.6 Evidence from animal studies suggests that DHLA protects the brain against free radical damage.7

Alpha-lipoic Acid and Blood Sugar

Alpha-lipoic acid is a key factor in the cellular process that metabolizes glucose to produce energy for cellular functions. The importance of ALA’s role in blood sugar metabolism is evidenced in studies on ALA and type-2 diabetes. In a small pilot study, 13 people with type-2 diabetes showed improved utilization of glucose in muscle tissue in response to intravenous administration of ALA.8 In a four week controlled multicenter trial, 74 people with type-2 diabetes took ALA in oral doses of 600, 1200 or 1800 mg per day. After 4 weeks, the normal lowering of blood sugar levels in response to insulin improved.9 In vitro studies have shown that ALA has a positive effect on insulin-stimulated uptake of glucose by muscle cells.10

Subject: Curcumin - Turmeric Extract

Curcumin

Turmeric- History and Traditional Usage

Native to Southeast Asia, Curcuma longa is a tall
tropical shrub with large oblong leaves and pale yellow flowers.
The genus “Curcuma” belongs to the Zingiberaceae family, which
includes ginger.1 The plant possesses a large root structure
with fleshy, bulbous underground parts called “rhizomes.” These
rhizomes, known as turmeric root, are harvested at maturity,
dried and cured for commercial use. Chemical analysis shows that
dried turmeric contains essential and volatile oils, with a
curcuminoid content of 2.5 to 5.0 %.2

In addition to its
popularity as a spice, turmeric is used as a dye for cloth and
coloring agent in foods and cosmetics, thanks to its rich yellow
color. Turmeric also serves as a preservative, probably owing to
the antioxidant and antimicrobial properties of curcumin.
Extracts of Curcuma longa have demonstrated in vitro
antibacterial and anti-fungal effects.3

Turmeric is named in
ancient Ayurvedic and Chinese herbal texts as a traditional folk
remedy. Historically, turmeric was used externally for wounds,
and sprains, and internally for digestive complaints,
rheumatism, liver disorders, coughs and colds.4
Benefits

Protects cells and tissues by fighting free radicals.*

Supports joint function*

The numerous beneficial
effects attributed to turmeric stem in large measure from the
antioxidant properties of curcumin. Antioxidants neutralize free
radicals, which are highly unstable molecules that can damage
cellular structures through abnormal oxidative reactions.
Curcumin is a potent “scavenger” of the Superoxide radical, a
free radical that initiates potentially harmful oxidative
processes such as lipid peroxidation.5 Through this activity,
curcumin has been shown to protect skin cells from the injurious
effect of nitroblue tetrazolium, a toxin that generates
Superoxide radicals. Curcumin also increases survival of cells
exposed in vitro to the enzyme hypoxanthine/xanthine oxidase,
which stimulates Superoxide and hydrogen peroxide production.
Curcumin itself is not toxic to cells, even at high
concentrations. Pure curcumin was shown to be less protective
than a mixture of curcuminoids, indicating a possible synergism
among curcuminoids.6 Because free radicals are involved in aging
and exert harmful effects on skin, these results suggest
curcumin may help slow skin aging.

Curcumin demonstrates
several other in vitro effects linked to free radical
scavenging. Curcumin scavenges nitric oxide, a compound
associated with the body’s inflammatory response.7 Pure curcumin
and turmeric extracts protect red blood cells from lipid
peroxidation induced by hydrogen peroxide.8 Curcumin has been
shown to protect DNA from oxidative damage, inhibit binding of
toxic metabolites to DNA, and reduce DNA mutations in the Ames’
test.9 Although additional studies suggest an anticarcinogenic
effect of curcumin, through protection of DNA,10 one in vitro
study found that curcumin induced DNA damage in human gastric
mucosal cells.11 It is speculated that curcumin may act as a
pro-oxidant in the presence of transition metal ions such as
copper and iron. (This is true for other antioxidants, including
vitamin C.) Curcumin also demonstrates in vitro inhibition of
COX-I and COX-II enzymes, which are involved in the inflammatory
reaction.12 Together these results strongly suggest that
curcumin is a potent bioprotectant with a potentially wide range
of therapeutic applications.

Animal studies- In vivo protective effects

Through its free radical scavenging
properties, curcumin has shown bioprotective effects in animals.
In one study, rats were treated with isoproterenol, a chemical
that causes cardiac hypertrophy (enlargement of the heart) due
to abnormal collagen metabolism. Co-treatment with curcumin
reversed the degradation of collagen and cardiac hypertrophy
induced by isoproterenol.13 Curcumin protects mice from
detrimental effects of radiation, by stabilizing the glyoxalase
system, a biological system that regulates cell division.14
Curcumin protects livers of rats from the damaging effects of
carbon tetrachloride (CCl4), a potent hepatoxin that injures the
liver via its free radical metabolite, CCl3.15,16 Curcumin
protected rats from alcohol-induced brain damage, in a study in
which oral administration of curcumin reversed lipid
peroxidation, reduced levels of free-radical metabolites and
increased levels of glutathione, a major physiologic
antioxidant.17 Curcuma longa extracts have shown
anti-inflammatory effects in rats.18

Human Trials

Curcumin exhibits free-radical scavenging ability when
administered to humans. In an open trial (uncontrolled), 18
healthy individuals ranging in age from 27 to 67 years consumed
a Curcuma longa extract, at a dose supplying 20 mg curcuminoids,
for 45 days. Before and after blood tests showed a statistically
significant decrease in lipid peroxides.19 Preliminary trials
have tested the anti-inflammatory action of curcumin, with
results that verify the traditional use of turmeric as an
anti-rheumatic herb. In a short-term double-blind, cross-over,
comparative study, 18 people received curcumin (1200 mg daily)
or phenylbutazone for two week periods. Both curcumin and
phenylbutazone produced measurable improvements in joint
flexibility and walking time. The subjects reported results only
with phenylbutazone, which may be explained by the short
duration of the trial.20 In a small placebo-controlled trial
comparing curcumin to phenylbutazone, 45 patients with
post-operative inflammation received curcumin, phenylbutazone or
placebo. The anti-inflammatory effects of curcumin and
phenylbutazone were comparable and superior to placebo.21
Curcumin has not been found to produce an analgesic (pain
relieving) effect.

Bioperine-Nature’s Absorption Enhancer
Boosts Curcumin Absorption*

Traditional Ayurvedic herbal
formulas often include black pepper and long pepper as
synergistic herbs. The active ingredient in both black pepper
and long pepper is the alkaloid, piperine. Experiments carried
out to evaluate the scientific basis for the use of peppers have
shown that piperine significantly enhances bioavailability when
consumed with other substances.22 Several double-blind clinical
studies have confirmed that Bioperine® increases absorption of
nutrients.23

Curcumin is poorly absorbed in the intestinal
tract, limiting its therapeutic effectiveness. Oral doses are
largely excreted in feces, and only trace amounts appear in the
blood. Concomitant administration of 20 mg of piperine with 2
grams of curcumin increases the bioavailability of curcumin by
2000%.24

Subject: Benfotiamine raises the blood level of thiamine pyrophosphate (TPP)

Benefits

Benfotiamine raises the blood level of thiamine pyrophosphate (TPP), the biologically active co-enzyme of thiamine.4

Thiamine and its Co-enzyme, TPP

Thiamine (vitamin B1) plays an essential part in the metabolism of glucose, through actions of it co-enzyme TPP (thiamine pyrophosphate). TPP is formed by the enzymatically-catalyzed addition of two phosphate groups donated by ATP to thiamine. TPP also goes by the name "thiamine diphosphate." In the cytoplasm of the cell, glucose, a 6-carbon sugar, is metabolized to pyruvic acid, which is converted into acetyl-CoA, otherwise known as "active acetate." Acetyl CoA enters the mitochondrion, where it serves as the starting substrate in the Kreb’s cycle (citric acid cycle). The Krebs cycle is the primary source of cellular metabolic energy. TPP, along with other co-enzymes, is essential for the removal of CO2 from pyruvic acid, which in turn is a key step in the conversion of pyruvic acid to acetyl CoA. CO2 removal from pyruvic acid is called "oxidative decarboxylation," and for this reason, TPP was originally referred to as "cocarboxylase." TPP is thus vital to the cell’s energy supply. Benfotiamine helps maintain healthy cells in the presence of blood glucose. Acting as a biochemical "super-thiamin," it does this through several different cellular mechanisms, as discussed below.

Benfotiamine and Glucose Metabolism Benfotiamine normalizes cellular processes fueled by glucose metabolites.

As long as glucose remains at normal levels, excess glucose metabolites do not accumulate within the cell. The bulk of the cell’s glucose supply is converted to pyruvic acid, which serves as substrate for production of acetyl CoA, the primary fuel for the Krebs cycle. Of the total amount of metabolic energy (in the form of ATP) released from food, the Krebs cycle generates about 90 percent.5 In the presence of elevated glucose levels, the electron transport chain, the final ATP-generating system in the mitochondrion, produces larger than normal amounts of the oxygen free radical "Superoxide." This excess Superoxide inhibits glyceraldehyde phosphate dehydrogenase (GAPDH), as key enzyme in the conversion of glucose to pyruvic acid, resulting in an excess of intermediate metabolites known as "triosephosphates." Increase triosephophate levels trigger several cellular mechanisms that result in potential damage to vascular tissue. Cells particularly vulnerable to this biochemical dysfunction are found in the retina, kidneys and nerves.

Benfotiamine has been shown to block three of these mechanisms: the hexosamine pathway, the diaglycerol-protein kinease C pathway and the formation of Advanced Glycation End-poducts. As discussed below, benfotiamine does this by activating transketolase, a key thiamin-dependent enzyme.6 Benfotiamine stimulates tranketolase, a cellular enzyme essential for maintenance of normal glucose metabolic pathways.* Transketolase diverts the excess fructose-6-phosphate and glyceraldehydes-3-phosphate, (formed by the inhibition of GAPDH, as mentioned above), into production of pentose-5-phosphates and erythrose-4-phosphate and away from the damaging pathways. Benfotiamine activates transketolase activity in bovine aortic endothelial cells incubated in glucose.6 To test benfotiamine’s ability to counteract these metabolic abnormalities caused by elevated blood glucose, studies have been done in diabetic rats. Benfotiamine increases transketolase activity in the retinas of diabetic rats, while concomitantly decreasing hexosamine pathway activity, protein kinase C activity and AGE formation.6

Benfotiamine and Protein glycation Benfotiamine controls formation of Advanced Glycation End-products (AGEs).

AGEs have an affinity for proteins such as collagen, the major structural protein in connective tissue. AGEs are formed through abnormal linkages between proteins and glucose. This occurs via a non-enzymatic glycosylation reaction similar to the "browning reaction" that takes place in stored food.7 At high glucose concentrations, glucose attaches to lysine, forming a Schiff base, which in turn forms "early glycosylation products." Once blood glucose levels return to normal levels, the amount of these early glycosylation products decreases, and they are not particularly harmful to most tissue proteins. On long-lived proteins such as collagen, however, early glycosylation products are chemically rearranged into the damaging Advanced Glycation End-products. AGE formation on the collagen in coronary arteries causes increased vascular permeability. This vessel "leakiness" allows for abnormal cross-linking between plasma proteins and other proteins in the vessel wall, comprising vascular function and potentially occluding the vessel lumen. A number of other potentially harmful events may also occur, including production of cytokines that further increase vascular permeability. Endothelin-1, a strong vasoconstrictor, is over produced, increasing the possibility of thrombosis and generation of oxygen free radicals is stimulated.8 It is vitally important to support normal glucose metabolic pathways so that formation of AGEs is minimized. Benfotiamine, in the test tube (in vitro) prevents AGE formation in endothelial cells cultured in high glucose by decreasing the glucose metabolites that produce AGEs.9 Endothelial cells make up the membranes that line the inner walls of organs and blood vessels. In a rat study comparing the effects of Benfotiamine with water-soluble thiamin, Benfotiamine inhibited AGE formation in diabetic rats while completely preventing formation of "glycooxidation products," which are toxic by products of chronic elevated blood glucose. AGE levels were not significantly altered by thiamin.10 Benfotiamine also normalized nerve function in the animals. After three months of administration, "nerve conduction velocity (NCV)," a measure of nerve function, was increased by both benfotiamine and thiamin; at six months, NCV was normalized by benfotiamine, whereas thiamin produced no further increases in this parameter.

Dysfunctional glucose metabolic pathways leading to AGE formation occurs in endothelial cells of the kidneys. In a recent animal study, benfotiamine was administered to rats with elevated glucose levels. Benfotiamine increased transketolase activity in the kidney filtration system of these rats, while at the same time shifting triosephophates into the pentose pathway and preventing protein leakage.11

Safety

Benfotiamine has an excellent tolerability profile and can be taken for long periods without adverse effects.3,12 The statements in this fact sheet have not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure or prevent any disease.

Subject: The Immune System - with Kyolic Garlic

The Immune System

The immune system is our body's natural defense system that keeps us healthy. Without it, invading organisms, which we come into contact with constantly, would cause illness and disease. There are many components of the immune system, including natural killer cells, T&B cells, macrophages and many others. Collectively, this network mainly functions against bacteria, viruses, fungi, and parasites.

It is possible for the immune system to be suppressed. Things like stress, unhealthy habits, lack of nutrition, genetics, and other factors damage the immune system, which leaves us vulnerable to disease.

The immune system can benefit from proper, and constant care. A healthy immune system can mean the difference between getting mildly sick versus something much worse. If you are looking for ways to boost your immune system via nutritional supplements, here are a few that might interest you:

Aged Garlic ExtractTM (AGE): Numerous scientific studies have been conducted on AGE in relation to its effect on the immune system. Studies suggest that Aged Garlic Extract may support various immune factors,1-5 such as the ability of immune cells to engulf foreign organisms, T-lymphocyte activity,3 natural killer cell activity1,2 and antibody generation.6 Anti-fungal (Candida albicans-yeast) properties have been shown, and antiviral (herpes1,7, influenza8,9) properties have also been noted. Aged Garlic Extract has also been shown to modify, directly or indirectly, the function of immune cells, which play a leading role in allergic reactions including inflammation.10 In addition, Aged Garlic Extract has been shown to improve age-related deterioration of the immune response.

For your convenience AGE is available as a liquid, and in a capsule, such as the Reserve, FORMULA 100 (tablet or capsule), or as the One Per Day (caplet).

AGE also comes in combination with other herbs and nutrients that may further enhance the immune system. We have formulated a couple of products containing Aged Garlic Extract, specifically for the immune system due to the additional ingredients added that work as an extra boost in this area. Firstly, FORMULA 103 (brown/orange label) in addition to Aged Garlic Extract contains Astragalus, a potent herb demonstrating immune stimulating properties12-17 and vitamin C as Ester-C® (a unique form of Vitamin C) which may support healthy immune function.18 Another product, FORMULA 105 (pink/purple label), contains Vitamins A, C, E, selenium and green tea extract, which are very potent antioxidants. Antioxidants attack free radicals that cause damage to our body, leading to illness and aging. Please keep in mind that the various antioxidant functions attributed to AGE may also help to boost the immune system.

Kyo-Green® is another one of our superb products. Mixing Kyo-Green in a juice or beverage may help to provide extra nutritional support since it is a source of vitamins, minerals, chlorophyll, Superoxide dismutase (a very potent anti-oxidant enzyme) and other nutrients. A test tube study by Dr. Lau from Loma Linda University showed that Kyo-Green may provide nutritional support for the immune system by enhancing the activity of macrophages (immune cells that engulf foreign agents).19 Two teaspoons of Kyo-Green also provide the nutrients in a serving of vegetables so this product may function as an easy way to provide extra nutrition for the whole body.

For those who may be interested in a more potent immune boosting formula, please try our Kyo-Green Harvest Blend The Harvest BlendTM contains all of the ingredients in the Kyo-Green, except for the kelp. However, in addition to these ingredients, other active ingredients are added to make forty-four ingredients in total, which may give the immune system a powerful kick. To help support your health there are many different greens, an immune-boosting herbal blend, antioxidant fruits and veggies, immune-enhancing mushrooms, an enzyme active sprout blend, a super energizing blend, special phytonutrients important to immune health, and a nutritious fiber blend. Please read the specifics on each of these constituents, available from the technical information available on this website.

Finally, Kyo-Dophilus® is a probiotic supplement made of a combination of Lactobacillus acidophilus, Bifidobacteria bifidum, and Bifidobacteria longum, which help to maintain a healthy balance of the intestinal microflora and increase our first line of devense in the guy by enhancing macrophages and other immune factors by releasing immune boosting materials. This potent supplement of beneficial bacteria is also ideal for those taking antibiotics, those who are traveling or for those who just want to insure a plethora of beneficial bacteria in their intestinal tracts. Antibiotics are not selective in the bacteria that they kill off. When our friendly bacteria are wiped out, the bad guys have a window of opportunity to take over, as they grow much quicker than our friendly bacteria, and cause us problems. The lactic acid (friendly) bacteria have been shown to produce vitamins, enzymes and antimicrobial compounds that may improve the environment in the intestinal tract. Studies also suggest that friendly bacteria may help to increase resistance to some microbial infections.20-21 Kyo-Dophilus has demonstrated incredible stability at room temperature maintaining more than one billion live cells per capsule through its three-year shelf life. A minimum of one billion live cells per day is considered to be necessary to obtain desired effectiveness from a probiotic supplement. Kyo-Dophilus also comes in tablet form, in a nine-strain formation known as Kyo-Dophilus® 9, and in a smaller form for children, Kid's Kyo-Dophilus®.

Supplying your immune system with adequate nutrition may promote health and ward of illness. If you give the body the tools it needs to heal it-self, it is amazing what it is capable of.

Subject: GLISODIN POWER - Superoxide Dismutase (SOD)

Most people know that antioxidants found in food are critical for health and longevity, but did you know that the human body has its own antioxidant defense system? Superoxide dismutase (SOD) is an internal antioxidant manufactured by the body as the first line of defense against free radical damage. Unfortunately, high levels of stress and exposure to environmental and dietary toxins can deplete our antioxidant stores, leaving us more susceptible to chronic health challenges. When we are young and healthy the body unleashes its own antioxidants, but as we age this internal antioxidant producing system declines and the body needs help.

Source Naturals introduces GLISODIN POWER, an innovative approach to antioxidant supplementation. Scientific research shows that GliSODin® supports the body’s own production of Superoxide dismutase. GLISODIN POWER is a patented, orally effective, 100% vegetable compound comprised of gliadin, a wheat protein extract bound to Superoxide dismutase derived from canteloupe.

Oxygen is required by your cells to generate energy, but it also contributes to oxidative stress or free radical damage, which is one of the primary causes of age-related damage to your cells and tissues. Free radicals have unpaired electrons that can damage living cells and compromise the proper function of tissues and organs. Antioxidants make free radicals stable by providing them with an additional electron. Unfortunately, now the antioxidant is missing an electron so, ironically, it becomes a free radical, which requires another antioxidant to donate an electron. Because this process starts a cascade of free radicals, scientists strongly recommend a broad range of antioxidants to minimize this negative effect.

First Line of Defense

There are two classes of antioxidants-external and internal. External antioxidants are supplied to the body by the foods we eat or the supplements we take. They include vitamins A, C and E, selenium, and other antioxidants found in fruits and vegetables. Internal antioxidants are naturally present in every cell of your body. The internal antioxidant defense system includes the enzymes Superoxide dismutase (SOD), catalase and glutathione peroxidase. They are the first line of defense against oxidative stress. SOD transforms the Superoxide radicals into ions that are less reactive. The Superoxide radicals, which are byproducts of normal cell processes, can damage cells if their levels are not controlled. The other enzymes then transform the less reactive ions in a process called dismutation. The Superoxide dismutase enzyme gets its name from this process. Research indicates that SOD plays an important role in protecting neurons from oxidative damage.

Super Antioxidant: SOD

SOD levels decline with age, while free radical production increases. SOD occurs naturally in barley grass, broccoli, Brussels sprouts, cabbage, wheat grass, melon and most green plants. Unfortunately, when taken orally the SOD enzyme is usually destroyed in the digestive process. GliSODin is a new form of SOD that withstands the digestive process and promotes SOD production by the body. This breakthrough technology combines a vegetable source of SOD extracted from melon with gliadin, a wheat protein. Scientific studies have shown that GliSODin promotes the natural production of SOD in the body. Research has also shown that it protects against oxidative stress and provides an optimal defense against free radicals.

Subject: RENEWAL ANTIOXIDANTS - The Most Comprehensive Antioxidant Formula Available

The average American’s life expectancy has risen dramatically over the last 100 years. Ideally those extra years will be quality ones. High levels of stress and exposure to environmental and dietary toxins can deplete our antioxidant stores, leaving us more susceptible to chronic health challenges. When we are young and healthy the body unleashes its own antioxidants, but as we age this internal antioxidant producing system declines and the body needs help. Free radicals cause oxidative stress, which is a major cause of accelerated aging. Source Naturals presents the science of RENEWAL ANTIOXIDANTS. This Bio-Aligned Formula™ is a significant advancement over other products currently available. No other formula provides the broad range of high potency, established and newly discovered water and fat-soluble antioxidants that RENEWAL ANTIOXIDANTS delivers.

Bio-Aligned Antioxidant Support

RENEWAL ANTIOXIDANTS™ supports multiple body systems with a balanced spectrum of plantioxidants™ (botanical extracts with unparalleled ability to combat free radicals), vitamins and specialty nutrients that have powerful antioxidant properties. Research suggests dietary antioxidants help balance and modulate free radical activity and help maintain structure and function of important components of cells such as lipids, proteins, and DNA.

Oxygen is required by your cells to generate energy, but it also contributes to oxidative stress or free radical damage, which is one of the primary causes of age-related damage to cells and tissues. Free radicals are unpaired electrons that can damage cells and compromise the function of tissues and organs. Antioxidants make free radicals stable by providing them with an additional electron. Unfortunately, now the antioxidant is missing an electron so, ironically, it becomes a free radical, which requires another antioxidant to donate an electron. Because this process starts a cascade of free radicals, scientists strongly recommend a broad range of lipid and water soluble antioxidants to minimize this negative effect. No other antioxidant formula follows the science better than RENEWAL ANTIOXIDANTS to defend against the widest spectrum of destructive free radicals, including peroxyl, hydroxyl, and Superoxide radicals, and singlet oxygen.

Healthy Heart

Antioxidants neutralize destructive free radicals and support cardiovascular health by halting the oxidation of cholesterol. Cholesterol is only harmful to us if it becomes oxidized. Oxidized cholesterol is an unstable molecule that damages arteries. RENEWAL ANTIOXIDANTS contains hearthealthy antioxidants including gamma E and tocotrienols, which are major lipid-soluble antioxidants that help maintain the integrity of cell membranes by preventing lipid oxidation. The formula includes hawthorn berry and grape seed, CoQ10, lycopene and other powerful antioxidants for heart support.

Nourishing the Brain

Antioxidants are critical for brain and nerve tissue because the brain is mostly composed of fats, which are very sensitive to free radical damage. Research has shown that stress can directly set in motion mechanisms that promote aging, which affects brain and nerve tissue. Ginkgo has been shown to increase memory performance and learning capacity as well as improve blood flow. It is also a free radical scavenger. RENEWAL ANTIOXIDANTS also contains DMAE, bilberry, CoQ10, grape seed, lipoic acid, vitamin B-2 and lutein for broad spectrum support.

Liver Support

Powerful antioxidants help minimize stress damage to liver cells and tissues, thereby supporting detoxification. N-acetyl cysteine is a powerful antioxidant. It is also a precursor to glutathione, a critical antioxidant and detoxifying substance produced in the liver. Silymarin is known for supporting the regeneration of the liver. Since the liver is prone to fat incursion, which makes it vulnerable to oxidative damage, the following fat soluble antioxidants provide critical protection: CoQ10, lipoic acid, ascorbyl palmitate, and gamma E.

Immune Defense

The immune system is unlike other body systems in that it is not a group of physical structures but a system of complex interactions involving many different organs. White blood cells generate enormous amounts of destructive free radicals in order to kill invading organisms. Vitamin C, a free radical scavenger, is concentrated in these white blood cells at a much higher level than in surrounding fluid. This extends their life and effectiveness by providing them with a built in defense mechanism against their own free radicals. RENEWAL ANTIOXIDANTS provides water and fat-soluble vitamin C (ascorbyl palmitate and ascorbic acid) along with vitamin A, beta carotene, CoQ10, lipoic acid, quercetin, selenium, gamma vitamin E, tocotrienols, zinc and turmeric, for added immune defense.

Skin & Connective Tissue

Skin is rich in lipids, proteins, and DNA, which are extremely sensitive to oxidation. Age-related changes due to oxidation, loss of elastic fibers and thickening of collagen fibers, cause skin to become fragile and less supple. A broad array of antioxidants protects skin and helps maintain its structure and tone. These include beta carotene, vitamin C, vitamin E, grape seed, zinc, amla (Phylanthus emblica), quercetin, DMAE, manganese and myricetin. Amla is a very effective herbal tonic. It is rich in polyphenols and vitamin C.

Clear Vision

Eye tissue is particularly prone to the effect of free radicals. Vision involves light being focused through the lens onto the retina. The macula, or center of the retina, receives the most light. However, sunlight is a powerful free radical generator. Lutein, a potent, fatsoluble antioxidant concentrated in the macula, helps maintain the integrity of the macula and the blood vessels that supply the macular region. The eye also has aqueous tissue that is better protected by water-soluble antioxidants, such as bilberry and grape seed. RENEWAL ANTIOXIDANTS provides these ingredients, along with lycopene, zeaxanthin, lipoic acid, vitamin A, beta carotene and ascorbyl palmitate to support healthy eyes.

Energy Generation

Mitochondria, the tiny energy factories within the cells, are the major source of free radicals produced by our own bodies. These components of cells produce ATP (the energy molecule) and provide energy for all cellular activity; therefore, antioxidants are crucial to keep the levels of oxidants they produce in check. RENEWAL ANTIOXIDANTS provides the antioxidant power of green tea, lipoic acid, zinc, vitamin B-2, CoQ10 and Mega H-, a source of electron rich hydrogen ions. Coenzyme Q10 is fat-soluble and its primary functions include activity as an antioxidant and as a cofactor in many metabolic pathways, particularly in the production of ATP in oxidative respiration.

DNA Protection

DNA, the blueprint for all molecules in the body, can be altered or damaged by oxidation. Protecting DNA is important for optimal health of all cells and tissues. According to invitro research, certain compounds, such as curcumin (from turmeric) and quercetin, can directly protect against strand-breakage and base oxidation. RENEWAL ANTIOXIDANTS contains these ingredients along with rosemary, pomegranate, raspberry, blueberry leaf, and carnosine. In in-vitro studies, L-carnosine reduced glycation, a process in which DNA and protein are damaged by glucose.

Subject: Anti-Aging Nutrients

Anti-Aging Nutrients by Edward C. Wallace, DC, ND Energy Times, February 3, 2000

What's the big deal about trying to live longer? As you grow older (and the American population grows older alongside you) you may want to postpone the inevitable. Few wish to hasten "the journey from which no traveler returns." But as we approach that final bon voyage, chances are we desire clear sailing-aging without disability and with a peaceful, easy feeling.

How Do We Age?

Science has long puzzled about what causes the wrinkles, pains and deterioration of aging. In the search for causes, two basic theories have won over the most proponents: The first holds that cells are programmed with biological clocks that predetermine how many times they can reproduce before becoming non-functional. This theory has been largely formulated by the researcher Leonard Hayflick, MD.

The second basic theory, introduced by Denham Harman, MD, PhD, in the mid 1950s, holds that cells eventually break down due to attack by caustic molecules called free radicals that cause oxidative stress.

Programmed Cell Theory

In the early '60s, Dr. Hayflick observed that human fibroblasts (cells from connective tissue) in the laboratory refused to divide more than about 50 times. Dr. Hayflick also found that even if he froze the fibroblasts after 20 divisions, they would remember that they only had 30 divisions left after thawing.

Fifty cell divisions have been called the "Hayflick limit." Based on this research, scientists theorize that cells maintain a genetic clock that winds down as old age ensues. Many researchers believe the hypothalamus gland is the force behind our aging clocks, signaling the pituitary gland to release hormones that cause aging.

Free Radical/Oxidative Stress Theory

The other popular theory of aging pictures the human body as a cellular battlefield where attackers called free radicals damage our cells and tissues, making them age. In this scenario, a process called oxidation is the chief aging villain. On a microscopic level, oxidation generally entails molecules or atoms losing electrons. (Gaining electrons is called reduction.) The molecules or atoms that take these electrons are oxidizing agents.

Free radicals are substances that can exist with missing electrons, making them readily able to donate or accept electrons and damage structures in cells. As such, they are highly reactive, binding with and destroying important cellular compounds. Most of the free radicals in your body are made during metabolic processes. More are added from the food you eat and environmental pollution. Most of these free radicals contain oxygen molecules. As each cell makes energy in little structures called mitochondria, free radicals result. These oxidant by-products can damage DNA, proteins and lipids (fats). Consequently, toxic by-products of lipid peroxidation may cause cancer, inhibit enzyme activity and produce mutations in genetic material that make you age faster.

DNA Repair Theory

Free radical damage to DNA can cause cells to mutate or die. Your body makes enzymes that can repair this damage and slow aging. But, over time, the amount of damage overwhelms the body's ability to fix things. As cells grow older, their ability to patch up DNA diminishes and the rate of damage proceeds faster than repair. The result: We age and eventually die.

What Can We Do?

The free radical theory of aging suggests that taking antioxidants (compounds known to prevent free radical damage) in our food or as supplements may slow aging.

In the publication Age (18 [51] 1995: 62), it was reported that "aging appears to be caused by free radicals initiated by the mitochondria at an increasing rate with age. Superoxide and hydrogen peroxide radicals formed by the mitochondria during normal metabolism are major risk factors for disease and death after about the age of 28 in developed countries. Antioxidants from the diet lower the production of free radicals without impairing essential reactions to maintain body function."

Antioxidant Protection

Common dietary antioxidants include: vitamins E and C, carotenes, sulphur containing amino acids, co-enzyme Q10 and flavonoids (a group of plant compounds or pigments responsible for the color in fruits and flowers). In addition, melatonin, DHEA and the amino acid compound glutathione may also prove of benefit.

Glutathione along with the enzyme glutathione peroxidase are an essential part of free radical "quenching." (Quenching means changing free radicals into benign substances no longer capable of harm.) Deficiencies may suggest a decreased capacity to maintain detoxification and metabolic reactions in which glutathione plays a role, resulting in increased free radical stress and/or lipid peroxidation. Drinking too many alcoholic beverages can result in glutathione deficiency.

In a study in which 39 healthy men and 130 healthy women between the ages of 20 and 94 were evaluated for glutathione levels, the older subjects had significantly decreased levels (especially in the 60 to 79-year-old group). The authors felt that physical health and longevity were closely related to glutathione levels (Jrnl Lab & Clin Sci 120(5), Nov. 1992: 720-725). Poor nutrition and/or deficiencies in essential micronutrients and many prescription medications may contribute significantly to detoxification capacity in an aged individual. All of these circumstances are common in the elderly.

Eating a poor diet that contains too many processed foods without many fruits and vegetables can compromise your body's ability to detoxify pollutants, toxins and other harmful compounds. That can set off metabolic processes capable of fomenting large increases in free radical stress that can accelerate aging. Unfortunately, even in a country as prosperous as our own, nutrient deficiencies are frequent, especially in older citizens.

Nutrition Deficiencies

A study that looked at what elderly people consumed compared their reported intake with the 1989 Recommended Dietary Amount (RDA) and 1980 RDA: One of four people consumed only two-thirds of the RDA for calories and 60% consumed less than two-thirds of the RDA for vitamin D. As for other nutrients, 50% were found to have inadequate zinc levels (less than two-thirds of the RDA), 31% lacked calcium, 27% were short of vitamin B6, 25% didn't get enough magnesium, 7% missed out on folate and 6% ate less than two-thirds of the requirement for vitamin C (Nutrition Reviews (II), September 1995: S9-S15).

When researchers examine what everyone in the U.S. eats, they find that only 9% of Americans consume the recommended five servings of fruits and/or vegetables per day (Proceedings of the National Academy of Sciences, Sept 1993).

A diet high in fruits and vegetables is naturally high in antioxidant compounds and is believed to help you live longer. Unfortunately, if you buy your produce in the supermarket, those fruits and vegetables may also be rich in pesticide and herbicide residues (Consumer Reports, March 1999). Obviously, organic produce lacks these residues. But, in any case, research continues to indicate that a diet low in meats and animal fat and high in vegetables protects against antioxidant damage.

Longevity Diets

A six-year study of 182 people over age 70 in rural Greek villages found that those following their traditional diet of olive oil, whole grain breads, fresh fruits and vegetables and wine were less likely to die during the study than those who consumed more red meat and saturated fat. The most important foods in lowering the risk of early death included fruits, vegetables, legumes (peas and beans), nuts, dairy products and cereals (BMJ 311, 1995: 1457-1460).

Another article in Epidemiology highlights the evidence that eating a vegetarian diet increases your chances of living longer. Included in this survey is a recent country-wide study of diet and health in China, showing that the traditional near vegetarian diet of 10% to 15% of calories coming from dietary fat reduced the chances of heart disease, diabetes and many types of cancers (Epidemiology 3[5], 1992: 389-391).

Staying Alive

Staying skinny and limiting what you eat may also increase longevity. Scientific studies have previously shown that being overweight can theoretically curtail your life, increasing the risk of heart disease, diabetes and other life-shortening conditions. Animal studies have also shown that restricting food can slow diseases associated with aging. Researchers believe that cutting calories helps your immune system stay younger by reducing the formation of substances that are called proinflammatory cytokines.

Specifically reducing your intake of fatty foods may decrease your chance of coming down with autoimmune diseases. Researchers think omega-6 fatty acid vegetable oils (like corn oil) may increase free radical formation and decrease levels of antioxidant enzyme messenger RNA in addition to other effects (Nutrition Reviews 53[4], 1995: S72-S79). Another study found that cutting calories lowers the levels of oxidative stress and damage, retards age-associated changes and extends maximum life span in mammals (Science 273, July 5, 1996: 59-63).

In yet another study, it was shown that caloric restriction early in the life of lab animals increased their life span by a whopping 40% (Australian Family Physician 23[7], July 1994: 1297-1305). Today's modern higher-fat, low-fiber diet with substantial sugar consumption represents everything the longevity researchers say you shouldn't eat.

Longevity and Exercise

Exercise may slow aging. When researchers looked at the exercise habits of 17,000 men, average age of 46, they found that those who took part in vigorous activity lived longer.

Exercise can improve both cardiac and metabolic functions within the body, while also decreasing heart disease risk. Even modest exercise has been shown to improve cholesterol and blood sugar levels (JAMA 273[15], April 19, 1995: 1179-1184). In a study of how exercise affects your chances of living longer, 9,773 men underwent preventive medicine examinations on two different occasions. When the researchers looked at who lived longest, they found the highest death rate was in men who were unfit during both physical exams.

The Treadmill of Life

The lowest death rate was in the men who worked out and were in good shape. The researchers concluded that for each minute increase in how long a man could keep treading on a treadmill (between the first and second exam) there was a corresponding 7.9% decrease in the risk of dying (JAMA 273 [14], April 12, 1995: 1093-1098).

Since exercise can increase oxygen consumption up to 10 times, boosting the rate of production of free radicals, researchers believe that older individuals need more antioxidant nutrients to protect them. In a paper published in Aging Clinical and Experimental Research (1997), researchers stated that if you regularly exercise in your golden years, you should take more antioxidant vitamins to compensate for this risk.

Longevity Supplementation

Melatonin is not often thought of as an antioxidant, but, instead, as a sleep aid. Melatonin, however, is an effective and efficient free radical scavenger and may help stave off the effects of aging. Melatonin protects against what are called hydroxyl free radicals. Research shows that older people's lack of melatonin may make them more susceptible to oxidative stress. In one study, researchers felt that new therapies aimed at stimulating melatonin synthesis may eventually lead to therapies for the prevention of diseases related to premature aging (Aging and Clinical Experimental Research 7[5], 1995: 338-339). Melatonin was shown to provide antioxidant protection in several ways.

Toning Down Enzymes

Melatonin can ease the effects of enzymes that generate free radicals, enhance the production of glutathione peroxidase (an antioxidant) and defuse the caustic action of free radicals that contain hydroxyls. In several studies, DHEA supplementation has been shown to potentially revive immune function in older adults (Exp. Opin. Invest. Drugs 4[2], 1995: 147-154).

In a study of 138 persons older than 85 years compared to 64 persons 20 to 40 years of age, scientists found that the younger people had four times as much DHEA in their bodies.

The researchers believe that our bodies make less and less DHEA as we get older. The authors of this study raise the possibility that declining DHEA may be partly to blame for our biological clocks running down (New York Academy of Sciences 1994: 543-552).

Vitamins E & C

A growing body of research also supports the benefits of taking vitamins E and C to hold off the effects of getting old. Researchers writing in Free Radicals and Aging (1992: 411-418) point out that as you get older your body is home to more and more free radical reactions that may lead to degenerative diseases like heart disease and arthritis. Research has found that in older people with exercise-induced oxidative stress, taking vitamin E every day may significantly fight off free radicals. (To investigate this effect, scientists measured waste products in urine that result from free radical reactions.) Their conclusion: Dietary antioxidants such as vitamin E may be beneficial.

Chronological Age Vs.Biological Age

Vitamin C also looks to scientists like a good anti-aging bet. Research in the Journal of Advancement in Medicine, (7[1], Spring 1994: 31-41) showed that folks consuming larger amounts of vitamin C were less likely to experience clinical problems at all ages. Those taking in less than 100 mg of vitamin C per day also suffered the most problems.

In this research, individuals over 50 years of age who daily consumed the largest amount of vitamin C were as healthy or healthier than the 40 year olds who were taking the least amount of vitamin C.

A similar relationship appears to exist for vitamin E and serum cholesterol levels. In a study of 360 physicians and their spouses, researchers found that people in their 50s who consumed more vitamin E had lower cholesterol than those in their 30s who were taking less.

And the longevity beat goes on: In a study evaluating environmental tobacco smoke and oxidative stress, researchers divided 103 people into three groups. Researchers blew smoke at 37 of these folks without protection while 30 of them got to breathe tobacco smoke but took antioxidant supplementation. Another 36 of them merely had to read magazines from doctors' offices. The results: After 60 days of supplementation the antioxidant folks had a 62% reduction in evidence of oxidative damage to their DNA. Cholesterol levels dropped and so did antioxidant enzyme activities. The researchers concluded that taking antioxidants provided a modicum of protection against environmental poisons.

The range of antioxidant nutrients used in this study included: beta-carotene, vitamin C, vitamin E, zinc and selenium as well as copper (Cancer Epidemiol Biomarkers Prev 7, November 1998: 981-988).

Carotenoids

When you mention carotene or carotenoids, most people think of the beta carotene that makes carrots orange. But more than 600 carotenoids are present in colorful vegetables and many of these misunderstood substances are more potent antioxidants than beta-carotene.

Carotenoids have been shown to destroy oxygen free radicals in lipids (fats), help protect our cells from the sun's ultra violet radiation and enhance our natural immune response (J. Nutr 119[1], Jan. 1989: 112-115).

Some evidence seems to show that how much carotenoids you (and other mammals) have in your cells may be the predominant factor in determining life span (Proc Natl Acad Sci 82 [4], 1985: 798-802). Therefore, a diet rich in carotenoids (leafy green vegetables, carrots, yams, sweet potatoes, squash, citrus fruits and tomatoes) along with supplementation seems to be just what the fountain of youth ordered.

Flavonoids

Flavonoids, a group of antioxidant plant pigments, seem to be able to protect specific organs. For instance, the flavonoids in milk thistle (Silybum marianum) have been used for ages for liver problems. Bilberry has been found protective for the eye and hawthorn for the heart and circulatory system.

Numerous studies have shown the many beneficial effects of flavonoids with perhaps the best known being the ability of anthocyanidins in wine and grape seed extract to help protect your blood vessels and capillaries from oxidative damage (Phytotherapy 42, 1986: 11-14; Am J Clin Nutr 61, 1995: 549-54).

Flavonoids are found in vegetables and such fruits as blackberries, blueberries, cherries and grapes. A diet rich in these foods helps ensure an adequate intake of these important nutrient compounds.

Amino Acid Health

Methionine and cysteine are sulphur containing amino acids (protein building blocks), both of which are essential in maintaining levels of glutathione, a substance that plays a major role in quelling free radicals. Studies have found that as we age, the level of these important amino acids in our bodies decreases. (NEJM 312 [1], 1985: 159-68). As it has been shown that adding cysteine to the diet of test animals can increase their life expectancy considerably, researchers believe these amino acids can help us live longer too.

Attitude & Behavior

Get more sleep! A recent study showed that men who habitually napped were less likely to have a heart attack. The men in this research who regularly napped for at least 30 minutes per day had about a 30% reduction in heart problems while those who napped for a full hour had a 50% reduction compared to non nappers. Naps of longer duration did not seem to increase the benefit. In the same research, investigators also found that spending time with a pet or merely contemplating nature could also improve cardiac health. Sensuality, optimism and altruism also appeared to have health benefits (Family Practice News, December 15, 1998: 14-15).

In another study, this one in American Psychologist, researchers from the University of California found that people who are self-indulgent, pampered and achieve by running roughshod over the competition are less likely to outlive their healthy peers. Being egocentric, impulsive, undependable and tough-minded were predictors of poor physical health and a shorter life. So loosen up and be nice to your fellow humans! (U.C. Davis Magazine, Fall 1995: 14).

Longevity at Last

While no one has suggested that taking supplements, eating vegetables or exercising can, as of yet, extend the human life span past the generally recognized limit of about 120 years, researchers believe they can improve your odds of longer life. And by staying healthier, your old age will be more enjoyable, too.

Subject: Nutrients for Longevity

Nutrients for Longevity by Edward C. Wallace, ND, DC Energy Times, September 1, 1999

What's the big deal about trying to live longer? As you grow older (and the American population grows older alongside you) you may want to postpone the inevitable. Few wish to hasten "the journey from which no traveler returns." But as we approach that final bon voyage, chances are we desire clear sailing-aging without disability and with a peaceful easy feeling.

How Do We Age

Science has long puzzled about what causes the wrinkles, pains and deterioration of aging. In the search for causes, two basic theories have won over the most proponents: The first holds that cells are programmed with biological clocks that predetermine how many times they can reproduce before becoming non-functional. This theory has been largely formulated by the researcher Leonard Hayflick, MD.

The second basic theory, introduced by Denham Harman, MD, PhD, in the mid 1950s, holds that cells eventually break down due to attack by caustic molecules called free radicals that cause oxidative stress.

Programmed Cell Theory

In the early '60s, Dr. Hayflick observed that human fibroblasts (cells from connective tissue) in the laboratory refused to divide more than about 50 times. Dr. Hayflick also found that even if he froze the fibroblasts after 20 divisions, they would remember that they only had 30 divisions left after thawing.

Fifty cell divisions have been called the "Hayflick limit." Based on this research, scientists theorize that cells maintain a genetic clock that winds down as old age ensues. Many researchers believe the hypothalamus gland is the force behind our aging clocks, signaling the pituitary gland to release hormones that cause aging.

Free Radical/Oxidative Stress Theory

The other popular theory of aging pictures the human body as a cellular battlefield where attackers called free radicals damage our cells and tissues, making them age. In this scenario, a process called oxidation is the chief aging villain.

On a microscopic level, oxidation generally entails molecules or atoms losing electrons. (Gaining electrons is called reduction.) The molecules or atoms that take these electrons are oxidizing agents. Free radicals are substances that can exist with missing electrons, making them readily able to donate or accept electrons and damage structures in cells. As such, they are highly reactive, binding with and destroying important cellular compounds. Most of the free radicals in your body are made during metabolic processes. More are added from the food you eat and environmental pollution.

Most of these free radicals contain oxygen molecules. As each cell makes energy in little structures called mitochondria, free radicals result. These oxidant by-products can damage DNA, proteins and lipids (fats). Consequently, toxic by-products of lipid peroxidation may cause cancer, inhibit enzyme activity and produce mutations in genetic material that make you age faster.

DNA Repair Theory

Free radical damage to DNA can cause cells to mutate or die. Your body makes enzymes that can repair this damage and slow aging. But, over time, the amount of damage overwhelms the body's ability to fix things. As cells grow older, their ability to patch up DNA diminishes and the rate of damage proceeds faster than repair. The result: We age and eventually die.

What Can We Do

The free radical theory of aging suggests that taking antioxidants (compounds known to prevent free radical damage) in our food or as supplements may slow aging.

In the publication Age (18 [51] 1995: 62), it was reported that "aging appears to be caused by free radicals initiated by the mitochondria at an increasing rate with age. Superoxide and hydrogen peroxide radicals formed by the mitochondria during normal metabolism are major risk factors for disease and death after about the age of 28 in developed countries. Antioxidants from the diet lower the production of free radicals without impairing essential reactions to maintain body function."

Antioxidant Protection

Common dietary antioxidants include: vitamins E and C, carotenes, sulphur containing amino acids, co-enzyme Q10 and flavonoids (a group of plant compounds or pigments responsible for the color in fruits and flowers). In addition, melatonin, DHEA and the amino acid compound glutathione may also prove of benefit.

Glutathione along with the enzyme glutathione peroxidase are an essential part of free radical "quenching." (Quenching means changing free radicals into benign substances no longer capable of harm.)

Deficiencies may suggest a decreased capacity to maintain detoxification and metabolic reactions in which glutathione plays a role, resulting in increased free radical stress and/or lipid peroxidation. Drinking too many alcoholic beverages can result in glutathione deficiency.

In a study in which 39 healthy men and 130 healthy women between the ages of 20 and 94 were evaluated for glutathione levels, the older subjects had significantly decreased levels (especially in the 60 to 79-year-old group). The authors felt that physical health and longevity were closely related to glutathione levels (Jrnl Lab & Clin Sci 120(5), Nov. 1992: 720-725).

Poor nutrition and/or deficiencies in essential micronutrients and many prescription medications may contribute significantly to detoxification capacity in an aged individual. All of these circumstances are common in the elderly.

Eating a poor diet that contains too many processed foods without many fruits and vegetables can compromise your body's ability to detoxify pollutants, toxins and other harmful compounds. That can set off metabolic processes capable of fomenting large increases in free radical stress that can accelerate aging. Unfortunately, even in a country as prosperous as our own, nutrient deficiencies are frequent, especially in older citizens.

Nutrition Deficiencies

A study that looked at what elderly people consumed compared their reported intake with the 1989 Recommended Dietary Amount (RDA) and 1980 RDA: One of four people consumed only two-thirds of the RDA for calories and 60% consumed less than two-thirds of the RDA for vitamin D. As for other nutrients, 50% were found to have inadequate zinc levels (less than two-thirds of the RDA), 31% lacked calcium, 27% were short of vitamin B6, 25% didn't get enough magnesium, 7% missed out on folate and 6% ate less than two-thirds of the requirement for vitamin C (Nutrition Reviews (II), September 1995: S9-S15).

When researchers examine what everyone in the U.S. eats, they find that only 9% of Americans consume the recommended five servings of fruits and/or vegetables per day (Proceedings of the National Academy of Sciences, Sept 1993).

A diet high in fruits and vegetables is naturally high in antioxidant compounds and is believed to help you live longer. Unfortunately, if you buy your produce in the supermarket, those fruits and vegetables may also be rich in pesticide and herbicide residues (Consumer Reports, March 1999). Obviously, organic produce lacks these residues. But, in any case, research continues to indicate that a diet low in meats and animal fat and high in vegetables protects against antioxidant damage.

Longevity Diets

A six-year study of 182 people over age 70 in rural Greek villages found that those following their traditional diet of olive oil, whole grain breads, fresh fruits and vegetables and wine were less likely to die during the study than those who consumed more red meat and saturated fat. The most important foods in lowering the risk of early death included fruits, vegetables, legumes (peas and beans), nuts, dairy products and cereals (BMJ 311, 1995: 1457-1460)

Another article in Epidemiology highlights the evidence that eating a vegetarian diet increases your chances of living longer. Included in this survey is a recent country-wide study of diet and health in China, showing that the traditional near vegetarian diet of 10% to 15% of calories coming from dietary fat reduced the chances of heart disease, diabetes and many types of cancers. (Epidemiology 3[5], 1992: 389-391).

Staying Alive

Staying skinny and limiting what you eat may also increase longevity. Scientific studies have previously shown that being overweight can theoretically curtail your life, increasing the risk of heart disease, diabetes and other life-shortening conditions. Animal studies have also shown that restricting food can slow diseases associated with aging. Researchers believe that cutting calories helps your immune system stay younger by reducing the formation of substances that are called proinflammatory cytokines.

Specifically reducing your intake of fatty foods may decrease your chance of coming down with autoimmune diseases. Researchers think omega-6 fatty acid vegetable oils (like corn oil) may increase free radical formation and decrease levels of antioxidant enzyme messenger RNA in addition to other effects. (Nutrition Reviews 53[4], 1995: S72-S79). Another study found that cutting calories lowers the levels of oxidative stress and damage, retards age-associated changes and extends maximum life span in mammals (Science 273, July 5, 1996: 59-63).

In yet another study, it was shown that caloric restriction early in the life of lab animals increased their life span by a whopping 40% (Australian Family Physician 23[7], July 1994: 1297-1305). Today's modern higher-fat, low-fiber diet with substantial sugar consumption represents everything the longevity researchers say you shouldn't eat.

Longevity and Exercise:

Exercise may slow aging. When researchers looked at the exercise habits of 17,000 men, average age of 46, they found that those who took part in vigorous activity lived longer.

Exercise can improve both cardiac and metabolic functions within the body, while also decreasing heart disease risk. Even modest exercise has been shown to improve cholesterol and blood sugar levels (JAMA 273[15], April 19, 1995: 1179-1184).

In a study of how exercise affects your chances of living longer, 9,773 men underwent preventive medicine examinations on two different occasions. When the researchers looked at who lived longest, they found the highest death rate was in men who were unfit during both physical exams.

The Treadmill of Life

The lowest death rate was in the men who worked out and were in good shape. The researchers concluded that for each minute increase in how long a man could keep treading on a treadmill (between the first and second exam) there was a corresponding 7.9% decrease in the risk of dying. (JAMA 273 [14], April 12, 1995: 1093-1098).

Since exercise can increase oxygen consumption up to 10 times, boosting the rate of production of free radicals, researchers believe that older individuals need more antioxidant nutrients to protect them. In a paper published in Aging Clinical and Experimental Research (1997), researchers stated that if you regularly exercise in your golden years, you should take more antioxidant vitamins to compensate for this risk.

Longevity Supplementation

Melatonin is not often thought of as an antioxidant, but, instead, as a sleep aid. Melatonin, however, is an effective and efficient free radical scavenger and may help stave off the effects of aging.

Melatonin protects against what are called hydroxyl free radicals. Research shows that older people's lack of melatonin may make them more susceptible to oxidative stress. In one study, researchers felt that new therapies aimed at stimulating melatonin synthesis may eventually lead to therapies for the prevention of diseases related to premature aging (Aging and Clinical Experimental Research 7[5], 1995: 338-339). Melatonin was shown to provide antioxidant protection in several ways.

Toning Down Enzymes

Melatonin can ease the effects of enzymes that generate free radicals, enhance the production of glutathione peroxidase (an antioxidant) and defuse the caustic action of free radicals that contain hydroxyls.

In several studies, DHEA supplementation has been shown to potentially revive immune function in older adults (Exp. Opin. Invest. Drugs 4[2], 1995: 147-154).

In a study of 138 persons older than 85 years compared to 64 persons 20 to 40 years of age, scientists found that the younger people had four times as much DHEA in their bodies.

The researchers believe that our bodies make less and less DHEA as we get older. The authors of this study raise the possibility that declining DHEA may be partly to blame for our biological clocks running down (New York Academy of Sciences 1994: 543-552).

Vitamins E & C

A growing body of research also supports the benefits of taking vitamins E and C to hold off the effects of getting old. Researchers writing in Free Radicals and Aging (1992: 411-418) point out that as you get older your body is home to more and more free radical reactions that may lead to degenerative diseases like heart disease and arthritis. Research has found that in older people with exercise-induced oxidative stress, taking vitamin E every day may significantly fight off free radicals. (To investigate this effect, scientists measured waste products in urine that result from free radical reactions.) Their conclusion: Dietary antioxidants such as vitamin E may be beneficial.

Chronological Age Vs. Biological Age

Vitamin C also looks to scientists like a good anti-aging bet. Research in the Journal of Advancement in Medicine, (7[1], Spring 1994: 31-41) showed that folks consuming larger amounts of vitamin C were less likely to experience clinical problems at all ages. Those taking in less than 100 mg of vitamin C per day also suffered the most problems. In this research, individuals over 50 years of age who daily consumed the largest amount of vitamin C were as healthy or healthier than the 40 year olds who were taking the least amount of vitamin C.

Similar Relationship

A similar relationship appears to exist for vitamin E and serum cholesterol levels. In a study of 360 physicians and their spouses, researchers found that people in their 50s who consumed more vitamin E had lower cholesterol than those in their 30s who were taking less. And the longevity beat goes on: In a study evaluating environmental tobacco smoke and oxidative stress, researchers divided 103 people into three groups. Researchers blew smoke at 37 of these folks without protection while 30 of them got to breathe tobacco smoke but took antioxidant supplementation. Another 36 of them merely had to read magazines from doctors' offices. The results: After 60 days of supplementation the antioxidant folks had a 62% reduction in evidence of oxidative damage to their DNA. Cholesterol levels dropped and so did antioxidant enzyme activities. The researchers concluded that taking antioxidants provided a modicum of protection against environmental poisons.

The range of antioxidant nutrients used in this study included: beta-carotene, vitamin C, vitamin E, zinc and selenium as well as copper (Cancer Epidemiol Biomarkers Prev 7, November 1998: 981-988).

Carotenoids

When you mention carotene or carotenoids, most people think of the beta carotene that makes carrots orange. But more than 600 carotenoids are present in colorful vegetables and many of these misunderstood substances are more potent antioxidants than beta-carotene.

Carotenoids have been shown to destroy oxygen free radicals in lipids (fats), help protect our cells from the sun's ultra violet radiation and enhance our natural immune response (J. Nutr 119(1), Jan. 1989: 112-115).

Some evidence seems to show that how much carotenoids you (and other mammals) have in your cells may be the predominant factor in determining life span (Proc Natl Acad Sci 82 [4], 1985: 798-802). Therefore, a diet rich in carotenoids (leafy green vegetables, carrots, yams, sweet potatoes, squash, citrus fruits and tomatoes) along with supplementation seems to be just what the fountain of youth ordered.

Flavonoids

Flavonoids, a group of antioxidant plant pigments, seem to be able to protect specific organs.

For instance, the flavonoids in milk thistle (Silybum marianum) have been used for ages for liver problems. Bilberry has been found protective for the eye and hawthorn for the heart and circulatory system.

Numerous studies have shown the many beneficial effects of flavonoids with perhaps the best known being the ability of anthocyanidins in wine and grape seed extract to help protect your blood vessels and capillaries from oxidative damage (Phytotherapy 42, 1986: 11-14; Am J Clin Nutr 61, 1995: 549-54).

Flavonoids are found in vegetables and such fruits as blackberries, blueberries, cherries and grapes. A diet rich in these foods helps ensure an adequate intake of these important nutrient compounds.

Amino Acid Health

Methionine and cysteine are sulphur containing amino acids (protein building blocks), both of which are essential in maintaining levels of glutathione, a substance that plays a major role in quelling free radicals. Studies have found that as we age, the level of these important amino acids in our bodies decreases. (NEJM 312 [1], 1985: 159-68).

As it has been shown that adding cysteine to the diet of test animals can increase their life expectancy considerably, researchers believe these amino acids can help us live longer too.

Attitude & Behavior

Get more sleep! A recent study showed that men who habitually napped were less likely to have a heart attack. The men in this research who regularly napped for at least 30 minutes per day had about a 30% reduction in heart problems while those who napped for a full hour had a 50% reduction compared to non nappers. Naps of longer duration did not seem to increase the benefit.

In the same research, investigators also found that spending time with a pet or merely contemplating nature could also improve cardiac health. Sensuality, optimism and altruism also appeared to have health benefits (Family Practice News, December 15, 1998: 14-15).

In another study, this one in American Psychologist, researchers from the University of California found that people who are self-indulgent, pampered and achieve by running roughshod over the competition are less likely to outlive their healthy peers. Being egocentric, impulsive, undependable and tough-minded were predictors of poor physical health and a shorter life. So loosen up and be nice to your fellow humans! (U.C. Davis Magazine, Fall 1995: 14).

Longevity at Last

While no one has suggested that taking supplements, eating vegetables or exercising can, as of yet, extend the human life span past the generally recognized limit of about 120 years, researchers believe they can improve your odds of living longer. An added benefit: By staying healthier, your old age won't only be longer, it will be more enjoyable, too.

And, who knows, if you hang around long enough, taking your nutrients and getting a comfortable amount of consistent exercise, while meditating and refusing to succumb to stress, that magic bullet that will keep you alive for centuries may be discovered. Some day a new antioxidant or other substance may finally prove to provide the elusive fountain of youth. Stay tuned.

Subject: Basic Detox

Basic Detox by Harriet Epstein , February 4, 2002

Basic Detox By Harriet Epstein Trying to stay healthy and clean in a dirty world can prove a difficult task. The rise of modern industry and agriculture has meant the widespread accumulation of toxins in our environment that can cause health problems.

As Kenneth Bock, MD, and Nellie Sabin point out in their book The Road to Immunity (Pocket), "Fat soluble chemicals are readily absorbed by the body but are difficult to excrete. To be excreted, they must first be enzymatically converted into water-soluble substances. Some of them can't be converted at all."

Bock and Sabin point out that a 1990 survey by the United States Environmental Protection Agency (EPA) that looked at people's tissues found that everyone the agency examined had styrene (a chemical used to make plastic) and xylene (a paint and gasoline solvent) stored in their bodyfat.

Toxin Exposure

The toxins that you encounter every day are not only present in air and water, but also may be found in food and medicines. If we eat beef that's been exposed to pesticides, those chemicals may be shunted into our bodyfat. Pesticide residues in fruits and vegetables may end up in a similar place.

To cope with chemicals, the human body has evolved methods for detoxifying. When we breathe out we often release inhaled toxins. Other toxins are purged through urine, feces and sweat.

One of the chief organs responsible for cleansing the body is the liver. This organ utilizes a pair of chemical pathways for breaking down and eliminating toxins. In our hectic, industrialized world, this flow of toxins can overwhelm the liver's ability to detoxify. In addition, the dual processes the liver uses to eliminate noxious substances may become unbalanced, allowing toxins produced by one pathway to build up to dangerous proportions.

Languishing Liver

Once liver function falters, toxic havoc ensues. Toxins may remain in the body, often stored indefinitely in bodyfat. The body's detoxifying systems may be swamped with toxins.

In protecting the liver and enhancing its detox functions, many naturopathic practitioners recommend the herb milk thistle (silybum marianum). According to Steven Bratman, MD, and David Kroll, PhD, authors of the Natural Health Bible (Prima), milk thistle helps the liver cope with its toxic load. Consequently, milk thistle is frequently used in Europe for liver problems like jaundice.

Bratman and Kroll point out that milk thistle "is one of the few herbs that have no real equivalent in the world of conventional medicine." As Lise Alschuler, ND, medical director at the Bastyr Natural Health Clinic, told Natural Digest, "Milk thistle protects the liver against toxic damage (and) helps prevent damage to the rest of the body."

Toxin Zappers

The compounds in milk thistle that help zap toxins, known as silymarin, protect the liver by binding with substances that would otherwise interact with the liver and slow its function. They also help the liver repair itself and regenerate new liver cells.

As an extra bonus, silymarin acts as an antioxidant, protecting liver cell membranes from oxidative damage.

Dandy Detox

Dandelion has a place as another traditional treatment for toning the liver and boosting the body's filtration system. The leaves are a cornucopia of antioxidants and nutrients including B vitamins, vitamins A, C and D, plus boron, silicon, potassium, magnesium and zinc. They help detoxify by acting as a mild diuretic: they cause the body to eliminate excess fluid.

But herbalists worldwide have found the compounds in dandelion root most useful for helping alleviate liver and gall bladder malfunction. (If you think you suffer these difficulties, consult your health practitioner.) Two unique and helpful natural substances found in dandelion root are chemicals called germacranolide and eudesmanolide. The root, according to the Natural Health Bible, has traditionally been used to speed up a sluggish or congested liver as well as detoxing the body by eliminating constipation. Research indicates dandelion root may stimulate bile flow (Arzneimittel -forschung 9, 1959: 376-378).

Juniper berries (Juniperus communis), may also be taken with dandelion as a diuretic. This botanical, often used to combat urinary tract problems, is also an anti-inflammatory (Phyto Res 1, 1997: 28-31).

Metal Problems

Heavy metals rank as dangerous toxins unleashed by modern industry. As Michael Murray, ND, and Joseph Pizzorno, ND, explain in the Encyclopedia of Natural Medicine (Prima), metals like lead, mercury, cadmium, arsenic, nickel and aluminum can "accumulate within the (body) where they can severely disrupt normal function."

Public health experts estimate at least one in five Americans has been a victim of heavy metal poisoning. Lead may be the most common villain. In your everyday life, you may be ingesting metals from your cookware, from pesticides, cigarette smoke, dental fillings, polluted fish, and chipping house paint.

Signs that you may suffer from toxicity linked to heavy metals: Unusual fatigue, Persistent headaches, Unexplained muscle pains, Anemia, Ringing in the ears or dizziness and Tremors.

Of course, if you think you suffer from heavy metal poisoning, you should see a knowledgeable health practitioner as soon as possible. Murray and Pizzorno recommend an array of precautions to protect yourself against heavy metals in the environment:

Take a daily multivitamin and mineral.

Take extra amounts of vitamin C and B-complex.

Take amino acids that contain sulfur (taurine, cysteine and methionine) and high sulfur foods like onions and garlic (or supplements). (Consult your pharmacist of health practitioner before taking individual amino acids.)

Consume water-soluble fibers like guar gum, oat bran, psyllium and pectin.

Smooth Digestion

In addition, Leo Galland, MD, in his book The Four Pillars of Healing (Random House) offers these tips for keeping your digestive tract functioning at top capacity:

Add spices to your foods and consume garlic, onion, turmeric, rosemary and sage to aid digestion.

Take supplements of lactobacil-lus acidophilus and lactobacillus plantarum, friendly bacteria that in-habit the large intestine. These microorganisms can help break down toxins and eliminate them.

Use aspirin and ibuprofen as little as possible. They increase the permeability of the digestive system, allowing allergens and other problematic substances to enter the body.

Do not use antacids. The stomach's acidic environment is designed to kill ingested bacteria and parasites.

To fight digestive problems or heartburn, cut back on saturated fat; eat smaller meals. Chewing on calcium tablets after meals may help. Foods that can exacerbate heartburn include coffee, alcoholic beverages and very spicy foods.

Dr. Galland also recommends not eating for four hours before bed.

Environmental Free Radicals

Detoxing the body may also require taking antioxidant nutrients to fight off what are called free radicals.

Free radicals are caustic molecues thought to be involved in causing many chronic problems such as cancer and heart disease. Free radicals are created within the body and its cells every time a metabolic activity takes place. While the human body has developed its own mechanisms for defending itself against these byproducts of metabolism, exposure to pollution, radiation and other toxins may overburden the body's free radical burden. Scientists believe that taking extra antioxidant nutrients like vitamins C and E and carotenoids (natural substances found in many vegetarian foods) may help prevent damage by free radicals.

Environmental oxidizing agents include ionizing radiation (from industry, sun, cosmic rays, x-rays) ozone and nitrous oxide (from auto exhaust) heavy metals (mercury, cadmium, lead) and cigarette smoke, along with other chemical and compounds from food, water and air. Free radicals are believed to play a role in more than sixty different health conditions, including the aging process, cancer and arteriosclerosis. (Proc Natl Acad Sci USA 1993;90:7915-7922).

The good news? Reducing exposure to free radicals and increasing intake of antioxidant nutrients can shrink the risk of these health problems.

Antioxidant focus

"Antioxidants can't get rid of heavy metals and solvents," says Dr. Glidden, "but they do cut down on the damage they do while they're there. As toxins wander through your body, they generate metabolic reactions, resulting in free radicals. And anti-oxidants mop them up." The liver is the last line of defense in handling toxins; supplements help it regenerate itself.

The body itself does produce enzymes like Superoxide dismutase (SOD) catalase, and glutathione peroxidase which can defend against and defuse many types of free radicals.

Supplements of these compounds are also available to augment the body's supply.

These building block nutrients include the minerals manganese, zinc, and copper for SOD and selenium for glutathione peroxidase. Many vitamins and minerals act as antioxidants. Dr. Crinnion recommends a multivitamin with "a lot of B, especially magnesium."

Since chlorinated pesticides like DDT "rob the body" of B1 and Vitamin A, he says, it's a good idea to supplement these as well.

In addition, acidophilus, a beneficial bacteria that grows in the digestive tract (and found in yogurt) may restore immunity hurt by pollutants. A study on women with recurrent vaginal candidiasis found that acidophilus cut their infections by 300% (Annals Int Med 1992; 116:353-357.)

Another immunity enhancer, colostrum, a natural immune enhancer that promotes cellular repair (Food Res Intl. 1995, 28(1):9-16) can also help the immune system battle pollution.

Vitamin C vs Pollution

A study of vitamin's C's antioxidant properties, conducted by University of Buffalo epidemiologists, and presented at the Annual Meeting of the Society of Epidemiologic Research, revealed that people with higher levels of vitamin C in their blood serum have lower levels of a marker of oxidative stress.

"It is well known that oxidative stress (cell damage caused by free radicals) plays a role in arteriosclerosis, cancer, pulmonary disease and other chronic conditions," said Holger Schunemann, M.D. a research assistant professor of social and preventive medicine at the University of Buffalo and lead author on the study.

"In this population, vitamin C was negatively associated with oxidative stress, suggesting it may play a role in protecting against these diseases." Vitamin C is the "greatest antioxidant," says Dr. Crinnion. "It has even been shown to clear lead from the blood."

Effective E

A powerful fat-soluble antioxidant, Vitamin E scavenges free radicals protecting cells from oxidative damage. Vitamin E, "reverses toxicity of various toxic chemicals," says Dr. Walter Crinnion, "it is also a stabilizer of membranes." A study published in the American Journal of Clinical Nutrition regarding antioxidant vitamin supplementation and lipid peroxidation in smokers even indicates that an antioxidant-supplemented drink can reduce lipid peroxidation and susceptibility of LDL to oxidation in smokers and may ameliorate the oxidative stress of cigarette smoke.

Dr. Glidden recommends E preferably in the form of mixed tocopherols )If you take blood thinners, check with your health practitioner.)

Unfortunately, completely avoiding toxins in today's world is probably impossible. Civilization and toxic chemicals accompany each other hand in rubber-glove-encased hand. Still, with proper attention to nutrition and supplements to keep our bodies detoxifying, we can probably minimize health difficulties linked to these undesirables.

Hearty Nutrients

by Lisa James Energy Times, January 3, 2002

An American suffers a heart attack every 20 seconds. That adds up to 180 heart attacks every hour. Many of these life-threatening events don't have to happen: heart-healthy nutrients, weight control and exercise could ease this epidemic.

More evidence of how to protect your heart piles up every day, amounting to a stack of research thicker than the juiciest, most heart-threatening cheeseburger on a big, fat bun. To protect your heart, you've got to protect your arteries, the blood vessels that carry blood from the heart and also feed the heart muscle oxygen and nutrients.

Arteries are essentially three-layered tubes: the inner endothelium, a middle muscle layer which allows the artery to widen and contract, and an outer layer that encloses and supports the other two. When the lining, which is normally smooth, is damaged, the resulting rough patch develops plaque from LDL cholesterol, and the artery narrows and hardens.

When LDL cholesterol is oxidized into plaque, the resulting damage attracts large immune cells called macrophages which consume the oxidized LDL and get trapped in the developing plaque. Oxidized LDL is also associated with the death of muscle cells in the artery's middle layer (Circulation 2000; 102:2680). Plaque slows blood flow to the heart and can result in angina, chest pain often brought about by exertion. Heart attacks strike when unstable plaque ruptures, triggering blood clotting that blocks blood flow and may kill sections of the heart muscle as it's cut off from oxygen and nutrients.

Foods, like fatty meats, filled with saturated fat, are believed to start this heart-threatening process. Even by age 15, your arteries may be narrowing.

Antioxidant Action

Antioxidants can help keep your arteries functioning smoothly by counteracting LDL oxidation. Lab research has shown that cells in the lining can be protected by natural vitamin E. Eating a diet rich in vegetables, fruits and whole grains is an important step in stocking your antioxidant arsenal. But many heart experts recommend supplementation, a strategy that's been shown to bolster the body's defenses (J Nutr Biochem 2001; 12:388-95).

Vitamins C and E: The Dynamic Duo

Antioxidant allies abound, but two of the most important are vitamin C and natural vitamin E. They work particularly well together because C is effective in the fluid that bathes all cells, while E defangs free radicals in the fatty areas, such as cell membranes. And vitamin C actually recharges vitamin E, increasing E's antioxidant effectiveness. Each vitamin provides protective benefits on its own. People with Type 2 (adult onset) diabetes who took vitamin E in one study saw drops in cholesterol and glucose and increases in antioxidants, such as Superoxide peroxidase, produced by the body itself (Endocr Res 2001; 27:377-86). For its part, vitamin C has prevented free radical damage in individuals who inhale secondhand cigarette smoke and has improved artery lining function in persons with coronary artery disease (Free Radic Biol Med 2000; 28:428-36; Circulation 1999; 99:3234-40). When used together, this vitamin dynamic duo provides powerful protection against both LDL oxidation and high blood pressure (Arterioscler Thromb Vasc Biol 2000; 20:2087-93; Hypertension 2000; 36:142-6). They also help keep immune cells from sticking to arterial linings (Circ Res 2000; 87:349).

Fighting Inflammation

Vitamins C and E also seem to prove effective against inflammation that researchers think contributes to heart health. Research in this area continues, but scientists now believe that inflammation from infections with herpes simplex one, the cold sore virus, and Chlamydia pneumoniae, a respiratory tract bug, can foment heart trouble. Inflammation may slow blood flow to the heart and make clots more likely. Among persons with peripheral arterial disease, blockages in arms and legs, not getting enough vitamin C levels may increase inflammation (Circulation 2001; 103:1863). Vitamin E apparently soothes inflammation by decreasing the release of immune chemicals and calming the immune cells involved in atherosclerosis (Diet and Optimum Health Conference, 5/01, Portland OR). Clot Busters Vitamin E also reduces the risk of clots and lowers the chance of a clot sticking in a vessel. It keeps platelets, cells that cause clotting, from becoming too gooey and breaks up fibrin, a clot-forming protein. Garlic (Allium sativa) also discourages inappropriate clotting. Used medicinally since the beginning of recorded time, the Greek physician Dioscorides thought it could clean the arteries. The ancient faith in garlic's circulatory benefits are supported by modern research. Recent studies have found substances in garlic that keep platelets from clumping together and lower cholesterol. In one study, men with high cholesterol who took garlic extract for five months saw their total cholesterol drop an average of 7% and their LDL drop 10% (J Nutr 2001; 131:989S-93S).

Hunting Down Homocysteine

Homocysteine, an amino acid found in the blood, may also be linked to artery problems. Scientists believe that when too much homocysteine accumulates in the bloodstream, arteries stiffen and plaque forms. The causes of this buildup remain murky but it appears that perpetually angry folks have higher homocysteine levels. Estimates vary on how much of a risk factor homocysteine represents; between 10% and 40% of people who suffer heart attacks may have high levels. Excessive homocysteine also seems to be linked to other risk factors, such as insulin resistance, a diabetes precursor (Diabetes Care 2001; 24:1403-10). The good news: the so-called DASH diet-featuring fruits, vegetables, low-fat dairy, whole grains, nuts and fish-may reduce homocysteine and drop your heart disease risk by 7% to 9% (Circulation 2000; 102:852-7). More benefits: simple B vitamins can control homocysteine. Folic acid (folate), along with vitamins B6 and B12, may help break it down and render it harmless. Taking these vitamins in supplement form has been shown to reduce homocysteine (Lancet 2000; 355:517-22). What's more, natural vitamin E may be able to restore artery lining function when homocysteine levels are high (Am J Cardiol 2001; 88:285-90). If you really want your ticker to tick stronger and longer, go long on your ready supply of heart healthy nutrients.

Subject: PYCNOGENOL ® - The Ultimate Antioxidant

Pycnogenol

Pycnogenol® is a breakthrough in antioxidant protection that demonstrates how important natural nutrition can be for your health. Antioxidants are a class of biological molecules that function to scavenge and neutralize free radicals. Free radicals are molecules with unpaired electrons that cause damage at the cellular level, and which unfortunately are unavoidable. Antioxidants – the most famous of which thus far have been Vitamin C and Vitamin E – work to protect living tissue by neutralizing free radicals, thereby interrupting many of their harmful activities. Pycnogenol®, one of the most powerful antioxidants yet discovered, is the proprietary name of a natural plant product made from the bark of the European coastal pine, Pinus maritima. It is 20 times more potent an antioxidant than Vitamin C, and 50 times more so than Vitamin E.

Free radicals are a real threat

Uniquely vulnerable targets of free radical attack that require a regular supply of antioxidants just to maintain a basic level of function include fatty acids – especially those in cell membranes – and sulfhydral proteins, which form one of the most common types of chemical bonds found in biological organisms. The importance of these substances for overall health cannot be overstated, as they are critical components not only of tissues throughout the body, but most importantly, of the principal regulatory organs – the brain and liver – and every blood vessel. Free radical attack on fatty acids – known as lipid peroxidation – and related destruction of sulfhydral proteins can lead to diminished function of cell membranes and whole organs. This, in turn, can contribute significantly to decreases in quality of life.

Free radicals are believed to be active in the development of cumulative damage to the system, as well as in many of the undesirable effects of aging. Free radicals are constantly being produced due to the natural intake of oxygen and generation of energy by the body’s cells. However, their production is heightened by pollutants such as tobacco smoke, alcohol, solvents, and oxidized cholesterol from foods. Therefore, health scientists suggest we may need to increase our intake of antioxidants either from foods or from supplements – such as Vitamin A and Beta Carotene, Vitamins C and E, Selenium, Cysteine, and now, Pycnogenol®.

Potent antioxidant protection from nature - Pycnogenol®

Originally discovered by renowned scientist Jacques Masquelier, Pycnogenol® is a natural 85% to 95% concentrate of proanthocyanidins extracted from the bark of the Maritime Pine. Proanthocyanidins are a special class of highly bioavailable, water-soluble bioflavonoids with unparalleled free radical scavenging activity. They readily cross the Blood-Brain Barrier to provide antioxidant protection to the central nervous system, and stay in the bloodstream for approximately 72 hours. Thirty years of sound European research shows that proanthocyanidins from Pycnogenol® are highly beneficial with no evidence of adverse effects, even after more than ten years of use. They also show no loss in potency after 12 years of storage.

Better health for an active life

As a potent antioxidant, Pycnogenol® is valuable for protecting the liver from free radical attack. Since the liver is the main detoxifying, nutrient-assimilating, and energy-generating organ of the body, this may mean more potential for activity in your life. Pycnogenol® may also aid recovery for athletes on strenuous workout regimes and in competition.

Healthy capillaries through healthy collagen

A major beneficiary of the protective actions of Pycnogenol® is collagen, the most abundant protein in the body. Collagen is responsible for maintaining the integrity of “ground substance,” the basic material in functional fluids, mucus linings, and connective tissue such as tendons, ligaments, cartilage, and most importantly, blood vessels linings. It is highly vulnerable to free radical attack, and a number of discomforting and depreciating processes are associated with its destruction. There is evidence showing that Pycnogenol® can provide remarkable support for the prevention of collagen destruction, and it has received much attention for its special affinity for capillaries, the smallest blood vessels. Pycnogenol® helps strengthen capillary linings in three key ways. First, Pycnogenol® functions to scavenge the free radicals that may compromise the integrity of collagen. Second, Pycnogenol® contains catechin, which is thought to stabilize collagen by forming hydrogen bonds and cross-linking collagen. Third, Pycnogenol® is Vitamin C-sparing, meaning it can fill in for C in a number of functions; this frees some Vitamin C – required for the synthesis of hydroxproline, a major structural amino acid of collagen – for use in building collagen. People who smoke and women who take oral contraceptives can reduce their heightened risk of Vitamin C depletion by taking advantage of Pycnogenol®’s Vitamin C-sparing activity.

Subject: Inflama Rest - Natural COX-2 Inhibitor for Joint Comfort

It happens. You reach for something and feel a sudden discomfort. Your joints and muscles may feel tender from overuse. Inside, your cellular systems are out of alignment, resulting in lessened mobility. Source Naturals understands how difficult joint discomfort can be to live with. We are deeply committed to developing well-researched formulas that address the root cause of joint distress. Our Bio-Aligned Formulas™ bring alignment to multiple interdependent body systems. Only this type of indepth formulation can provide the long-term relief you are looking for. Regain your comfort with Source Naturals INFLAMA-REST. Unlike many products that contain just a few ingredients to offer temporary relief, INFLAMA-REST is a Bio-Aligned Formula™, scientifically designed to address aches. INFLAMA-REST goes deep to the underlying cause of joint discomfort. These systems include: inhibition of pathways involved in joint discomfort, joint and muscle function, DNA protection and antioxidant defense.

Addressing Joint Comfort on a Deep Cellular Level

Discomfort can come from many places. From your head to your toes there are many tissues that can become uncomfortable from everyday use. Joint discomfort starts when stress, such as tissue damage, causes an imbalance of the biochemical pathways on a deep cellular level. The body has its own “innate intelligence” encompassing more than just the thoughts in the brain. It consists of ongoing and complex chemical reactions regulated by a wide variety of enzymes and chemical messengers. These reactions can sometimes get out of balance – but you can control and inhibit key body chemicals that would otherwise lead to cellular irritation. For example, certain types of prostaglandins that regulate normal physiological functions such as blood flow, are maintained at low levels in all our cells under everyday conditions. In response to stress, a message is sent to the outer membranes of certain cells to convert their fatty acids into arachidonic acid, the raw material for prostaglandins. This stress also directs cells to produce Cyclooxygenase enzyme- 2 or COX-2. This enzyme converts arachidonic acid into Prostaglandin E2, a particular type of prostaglandin specifically responsible for irritation on a cellular level. The result: joint discomfort. But that doesn’t have to happen. By supporting inhibition of the culprit COX-2, you can decrease Prostaglandin E2 production to bring your joint tissues back into a healthy and comfortable balance.

Support COX-2 Inhibition

INFLAMA-REST includes herbs that support inhibition of COX-2 in a variety of pathways. Ginger, turmeric and green tea all support direct COX-2 inhibition. But there are other places in our biochemical communication system where COX-2 production can be inhibited. Two additional factors that lead to COX-2 production are nitric oxide and the enzyme that produces it, nitric oxide synthase (iNOS). Nitric oxide is a free radical associated with cell growth and regeneration, blood vessel elasticity and COX-2 enzyme production. Resveratrol, rosemary and turmeric support iNOS inhibition, thus inhibiting your body’s over-production of nitric oxide and the COX-2 enzyme. A related irritation factor is also one of the latest scientific discoveries in cellular health - Nuclear Factor kappa-B (NF-kappa-B). NF-kappa-B works at the DNA level – at the blueprints of cells. When activated, this factor controls the genes that regulate cell growth, differentiation and regeneration. And blocking this factor is also associated with inhibition of both COX-2 and iNOS enzymes. Stinging nettle, milk thistle and Chinese Skullcap all block unhealthy NF-kappa-B activation in your body and thereby help support COX-2 inhibition.

Cytokine Inhibition

Compounds called cytokines, or interleukins, can also stimulate biochemical pathways leading to joint discomfort. Cytokines are chemical messengers produced by the immune system to regulate defensive activity when they are stimulated. For example, cytokines are released by macrophages in response to stimuli such as tissue damage. This results in rapid escalation and amplification of cell number and response. Constant stress can shift this system out of balance, resulting in tissue discomfort. Bringing these compounds back into balance can preserve your short-term comfort and longterm health. INFLAMA-REST contains curcumin from the spice turmeric. Curcumin assists the body’s inhibition of cytokine activity to support reduced cellular irritation. And Bioperine®, which is derived from black peppercorns, is added to assist curcumin assimilation.

Stress Response: Joints and Muscle Support

Inhibition of chemical messengers involved in joint discomfort is just part of a Bio-Aligned strategy for relieving discomfort. Research has shown that emotional stress, particularly long-term, can directly affect the body and set in motion mechanisms that cause physical discomfort. Ashwaganda and Chinese Skullcap (S. baicalensis) are herbs that help modulate the body’s response to stress and may help ease aches and discomfort. Boswellia, ginger, quercetin, milk thistle, feverfew, Oregon grape root and bromelain (an enzyme found in pineapples) provide additional soothing relief to your cells and tissues. Essential nutrients are also vital to maintaining your joint comfort. The tocotrienol forms of vitamin E, along with selenium, protect cell membranes from lipid-based free radicals. Magnesium aids energy metabolism in muscles and can reduce tenderness as well as muscle spasms. Zinc is essential for normal cellular repair mechanisms such as wound healing and is important for the growth and maintenance of connective tissue. And manganese works to protect cells from oxidation and to build healthy connective tissue as well, an essential component of healthy joints and muscles.

Protecting Your DNA

To reduce cellular irritation, you need to protect the DNA in your cells. DNA is the blueprint for all of the molecules in the body. If your DNA is altered or damaged, then needed molecules may not be produced, leading to short-term and eventually long-term damage. Curcumin, from turmeric, has been shown in in-vitro studies to protect DNA against strand breakage. Quercetin has also been shown to directly protect DNA against strand breakage and base oxidation from free radicals and damaging chemicals, according to recent in-vitro research.

Providing Powerful Antioxidant Cellular Protection

Antioxidants are selfless bodyguards of your cells. They donate their own electrons to stabilize free radicals in your body. Thus, antioxidants absorb the damage that would have been done to your tissues. Some regulatory chemicals, such as Nitric oxide, are powerful free radicals and oxidants. Oxidants also activate NF-kappa-B. Tissues, lipids, proteins and DNA are extremely sensitive to oxidation. Quercetin, milk thistle, turmeric, ginger, rosemary, vitamin E and resveratrol are all antioxidants that help modulate the activity of these compounds as well as protect cells and tissues from damage. Plus, Superoxide Dismutase (SOD), one of the most important enzyme antioxidants found in your body, has been added in a new cutting-edge form. The vegetarian SOD used in INFLAMA-REST is attached to Gliadin, a wheat protein, that has demonstrated significantly better absorption than SOD alone.

Six Lifestyle Strategies for Fewer Aches

1. Try Yoga or Tai Chi. Low-impact exercise based on slow fluid movements can improve mobility and flexibility as well as greatly reduce stress.
2. Get in the pool. Exercising while in the pool reduces strain on the joints in addition to strengthening muscles.
3. Maintain a healthy weight. Excess weight adds pressure to joints and connective tissues.
4. Eat omega-3s. Omega-3 fatty acids found in salmon, flax seeds, or in supplement form support healthy joints and tissues.
5. Stay hydrated. Water is the basis of lubrication in connective tissues such as joints and skin and also supports detoxification.
6. Supplement with glucosamine, chondroitin, MSM and hyaluronic acid. These supplements can help maintain healthy connective tissues. Source Naturals is pleased to partner with your local health food store to provide INFLAMA-REST as a comprehensive Bio- Aligned Formula for relieving joint discomfort by protecting, nourishing and soothing irritated cells. Make INFLAMA-REST part of your health plan to live without joint discomfort.

Garlic Inhibits Free Radical Generation and Augments Antioxidant Enzyme Activity in Vascular Endothelial Cells

Author:
Wei Z, Lau BHS

Source:
Nutrition Research. 1998; 18(1):61-70.

Abstract:
Oxygen free radicals have been implicated in mediating various pathological processes such as ischemia, inflammatory diseases, diabetes, and atherosclerosis. The antioxidant enzymes - Superoxide dismutase (SOD), catalase (CAT) and glutathione peroxidase (GPX) - play an important role in scavenging oxidants and preventing cell injury. Aged Garlic Extract (AGE) has been shown to prevent oxidant-induced injury of endothelial cells. The present study determined the effects of AGE on the generation of hydrogen peroxide (H2O2) and Superoxide anion (O2-) and the activity of three antioxidant enzymes in bovine pulmonary artery endothelial cells (PAEC). Confluent monolayers of PAEC were incubated with AGE, and oxidative stress was triggered by hypoxanthine and xanthine oxidase or H2O2. AGE exhibited both concentration- and time-dependent suppression of H2O2 and O2- generation, and it also significantly increased the activities of SOD, CAT and GPX The results suggest that AGE may be an effective antioxidant in preventing or treating disorders related to endothelial cell injury associated with free radicals.

Subject: Guggul – New Benefits for Heart Health

Gum Guggul–New Benefits for Heart Health from an Age-Old Herb

The 1990's have seen a growing interest in herbs from India's ancient Ayurvedic tradition. One Ayurvedic herb in particular, "gum guggul," stands at the forefront, thanks to its rather remarkable benefits for the heart and cardiovascular health. A relative of myrrh and frankincense, gum guggul is a resin tapped from India's Commiphora mukul tree. Known more commonly in the Far East as simply "guggul," the herb has proven to be one of the most effective natural cholesterol-lowering agents ever discovered. Cholesterol reductions with guggul can be twenty percent or higher, and the herb also raises HDL, the more beneficial form of cholesterol. Studies also show guggul may help prevent atherosclerosis, by retarding the formation of fatty, cholesterol-laden deposits in blood vessel tissues.

Recent research on guggul has revealed that guggul also blocks the oxidation of LDL cholesterol, by acting as an antioxidant. LDL, which carries cholesterol from the liver to the rest of the body, is generally regarded as a key element in the development of atherosclerosis. But only when it is oxidized by free radicals does LDL accumulate in arteries. It its unoxidized or "native" state, LDL is more or less benign. Checking LDL oxidation is vital to keeping blood vessels free of plaque.1 (This is one of the major reasons why antioxidants are so important.) Guggul, by both lowering blood cholesterol and acting against LDL oxidation, now stands out as one of the world's most valuable herbs for heart health.

Guggul first caught the attention of the scientific world in1966, thanks to an Indian medical researcher who submitted a doctoral thesis on gum guggul.2 Her interest had been kindled by references to the herb in a centuries-old Ayurvedic text. Apparently, poor cardiovascular health and atherosclerosis were a problem back then just as they are today. Translated from Sanskrit, this text describes, in elegant detail, a condition called "coating and obstruction of channels." The cause, according to the ancient writers? Faulty metabolism due to overeating of fatty foods and lack of exercise. Death was said to be the end result of leaving this condition uncorrected. The recommended treatment plan emphasized diet and herbs, chiefly gum guggul.3

References to guggul in ancient literature actually go back even farther. The herb is mentioned in the Vedas, the holy scriptures of India believed to be anywhere from 3,000 to 10,000 years old. One stanza is translated as follows: "Disease (consumption) does not afflict and the curse never affects whom the delicious odor of the healing Guggul penetrates (spreads). The diseases also flee away in all directions from him like horses and deer, O Gugulu! Either born from Sindhu or from the sea. I chant your name for the removal of diseases."3

Struck by the obvious similarity between "coating and obstruction of channels" and atherosclerosis, the Indian researcher decided to study gum guggul's effect on blood fats in rabbits. Over a two-year period, the animals were fed hydrogenated vegetable oil to artificially raise their cholesterol levels. Guggul was administered to one group of rabbits, while the rest served as controls. At the end of the study the rabbits given guggul had normal cholesterol and blood lipid levels. Their arteries showed no fatty streaks or plague deposits. This caught the attention of the Indian scientific community, and numerous clinical trials ensued, both on animals and humans. In study after study, guggul consistently produced substantial reductions in cholesterol and triglyceride levels, while raising HDL.

The active ingredients in guggul are a group of natural plant sterols. Among these, substances called "guggulsterones" are the most important ingredients for the cholesterol and blood fat lowering properties of guggul, with the other sterols acting as a synergistic supporting cast.4 A number of mechanisms are suggested, although not definitely proven, for how the herb works; these include reducing the synthesis of cholesterol in the liver, enhancing cholesterol removal from the gut, stimulating thyroid function and increasing the number of receptors in the liver for uptake of LDL.3,5

Guggul extracts are now standardized for guggulsterone content. The herb naturally contains about 2 percent guggulsterones. Quality extracts contain a minimum of 2.5 percent, which assures the user is getting a product potent enough to produce results. Since the late 1980's clinical trials have used the standardized extract.6,7,8 The product is readily available in the U.S.

The ability of guggulsterones to prevent oxidation of LDL was discovered in a 1997 study done by scientists at the Central Drug Research Institute in Lucknow, India.9 This study sheds light on how guggul works against "coating and obstruction of channels." Remember that oxidized LDL forms the plaque that coats and eventually obstructs blood vessels. The researchers mixed LDL from human blood with a free radical promoting agent, either alone or in combination with guggulsterones. Samples were then analyzed for the presence LDL oxidation byproducts. The results showed that guggulsterones strongly protect LDL from being oxidized. Guggulsterones block the formation of hydroxyl radicals, a potent type of free-radical that attacks cell membranes.

Guggulsterones may also help keep the heart muscle itself healthy. When the heart muscle is deprived of oxygen, a condition known as "myocardial ischemia," it can be severely damaged by free radicals. The body tries to counter this with SOD, a key enzyme present in cells that neutralizes free radicals. SOD levels are significantly reduced in damaged heart tissues. Guggulsterones have been found to reverse this decrease by more than two-fold.10

Like the writer of that age-old verse found in the Vedas, contemporary herbalists hold gum guggul in the highest regard. Backed as it is by scientific research linked to centuries of traditional use, gum guggul has a bright future as a natural resource for maintaining normal cholesterol and blood fats, and for protecting heart health.
