Alpha Lipoic Acid
December 11, 2008 11:19 AM
Alpha lipoic acid is the ideal antioxidant for five main reasons. It can scavenge free radicals of all kinds of both fat and water-based cell structures. It rapidly assimilates and absorbs into cells. Alpha lipoic acid boosts the action of other protective compounds. It Chelates free meal ions and it also promotes normal cell replication.
Alpha lipoic acid (ALA) is both fat and water soluble, which makes it a superior free-radical scavenger because it can protect lipid (fat) and aqueous (water) cell parts from free-radical damage. This ability allows ALA to offer excellent cellular protection because it can easily transport across cell membranes and give oxidant protection outside and inside cell structures. ALA has the ability to freely move throughout all cell parts, scavenging for free radicals in a way that is definitely more effective than other antioxidant compounds. Vitamin C, for example, is a good antioxidant but is strictly water soluble and only affects the interior of cells. On the other hand, vitamin E is only fat soluble, meaning that it affects only the lipid portion of cell structures or the membrane, which leaves other areas unprotected.
Cellular glutathione, which is produced in the body and works to neutralize free radicals, is very difficult to artificially boost. Although oral glutathione supplements are available, they have to go through the GI route before they enter the blood stream, leaving little glutathione which actually survives this process. Because of this, cellular levels are not significantly increase by oral supplementation. ALA has been found to help regenerate glutathione by providing extra cellular protection.
If the body becomes deficient in ALA, other antioxidant compounds may not work well. ALA plays an important role in boosting the activity of protective compounds such as vitamin E. ALA dramatically extends the life and effectiveness of other vital compounds.
ALA has been used for decades to treat diabetic conditions and complications including diabetic neuropathy, with ALA actually having the ability to initiate a reverse in the condition in some cases. Additionally, ALA helps to boost glucose uptake and results in less insulin dependency in some cases. Among its other properties, ALA can protect brain tissue on a cellular level, as well as protect brain cells from certain hazardous chemicals.
Research has shown that ALA may even play a role in the treatment of neurological disorders such as Huntington’s disease. As we are all aware, LDL cholesterol has a huge role in the development of cardiovascular disease. LDL cholesterol, which is particularly susceptible to free-radical damage, can be protected by ALA from free radical damage itself. Along with the above properties, ALA has been shown to help in strokes, cancer, cataracts, HIV, liver regeneration, and detoxification.
ALA can be purchased in tablet and capsule form and works well when it is orally ingested so that it can be easily assimilated through the walls of the gastrointestinal tract. Taking between 40 to 50 mg of ALA is recommended for best results. The primary applications of alpha lipoic acid are aging, aids, alcoholism, atherosclerosis, bell’s palsy, cataracts, cancer, cirrhosis, diabetes, diabetic neuropathy, multiple sclerosis, liver disease, radiation sickness or exposure, Alzheimer’s disease, senile dementia, stroke, Huntington’s disease, Parkinson’s disease, and heavy-metal poisoning.

Looking For A Calcium But Not Sure Which Is Best For You?
November 02, 2007 12:23 PM
Calcium is essential to good health, but if you are looking for calcium it can be confusing to decide in which form you take it. There are so many available and every one claims to be good for you, so why the difference? Why not just sell the best and let us all know what it is? Well, this same argument could be applied to all supplements that are sold in different forms, and also to many foodstuffs.
The supplement best for you might not be the best for the next person due to dietary requirements each persons diet is different, so it is better to learn about what is available then make your choice based upon knowledge rather than ignorance. It is not only the source of the calcium you have to bother about, but also the other vitamins that have be present to make sure that that the calcium is absorbed by the body in the way that you want it to be.
To understand that then you need to learn why the body needs calcium, other than just the bones and teeth that everybody knows about. After all, why else do we need calcium? It is only contained in bones and teeth – right? Wrong!
Although 99% of calcium is contained in your bones and teeth, 1% is contained in the blood, muscles and central nervous system. With out that 1% we would all die. Without teeth we would not. Calcium is essential for blood clotting and for the proper function of our muscles, brain and central nervous system. Calcium combines with phosphorus to create healthy bones and teeth, and is essential early in life to build up a strong skeleton. Note that phosphorus is also necessary so we also need an adequate supply of that mineral.
Calcium is essential to allow muscles to properly contract. Without that ability, muscles could not work, and a deficiency of calcium causes muscle cramps and spasms. The movement of the smooth muscles is regulated by a protein that is bound to calcium. This is just one of the uses of the calcium in the body that most people are unaware of.
Calcium also takes part in the binding process of the blood platelets during the coagulation of blood. Although most people are aware of the need for vitamin K and fibrin, in fact calcium is also essential in its interaction with the platelets in the coagulation cascade that eventually results in a blood clot that stops bleeding. Basically, without calcium, the blood could not form a clot. In addition to its effect on blood clotting, calcium also plays an essential part in the movement of ions through the membranes of nerve cells, and without it intercellular communication could not occur. Our nerve impulses would not occur and the body again would not be in a working condition.
However, the body has a way of modulating the calcium level in the blood past a minimum level needed for effective nerve cell communication, and below a certain level it can even use the calcium in the bones to divert to the more needy areas of the body. It is therefore not possible for the body to fail through a lack of calcium. The skeleton would disintegrate first. Nevertheless, nobody wants a disintegrating skeleton since that would be counterproductive to effective movement of the body, so a good source of calcium is essential for overall bodily health, not just that of the teeth and the bones.
There are many sources of calcium, but some are more suitable for absorption by the body than others. Chalk, or calcium carbonate, is an excellent source of calcium, but will fail to promote bone growth if your diet does not contain sufficient potassium, vitamin D, magnesium and strontium needed to make it work to build healthy bones. It is the most common on the shelves, and likely the cheapest, but not necessarily the best source. It is basically chalk or limestone, and only 10% of the supplement will actually become available for your body to use.
The bioavailability of a calcium supplement is a figure that indicates how much of the calcium is actually absorbed by the body during digestion. It is important that the supplement is digested and absorbed properly or the calcium will not be available for use. This availability is called the ‘bioavailability’. Calcium citrate has a bioavailabilty of 50%, but the size of the citrate part of the molecule is so large that only 10.5% of the molecule is available to the body as calcium. Not much more than the carbonate.
Calcium aspartate is highly soluble and produced by reacting calcium with aspartic acid to form the soluble salt. It is much easier to assimilate and be absorbed by the body than any of the forms above. The amino acid, aspartic acid, delivers the calcium exactly to where it is needed, where it is absorbed and used. Although a bioavailability figure is not available, it is not the amount of calcium that is significant here but the fact that it comes with its own transportation system and is immediately available where needed.
If you want to calculate the availability for yourself, find the molecular weight of the particular calcium product, and then the weight of the calcium contained within it. For example, in calcium carbonate, CaCO3, the molecular weight is 100 (40 + 12 + 3x16) and the atomic weigh of calcium is 40, so the amount of calcium present in 1000g calcium carbonate is 40% or 400g. Only 25% of calcium carbonate is absorbed, so only 10%, or 100g, of calcium is available for each 1000g supplement.
Calcium citrate on the hand (Ca3(C6H5O7)2.4H2O) has a molecular weight of 570, so the amount of calcium present is 3*40*100/570 = 21%. Since the bioavailability of calcium citrate is 50%, the amount of calcium available is only 10.5%, or 105g in 1000g citrate. You can carry out the same calculation on all the molecules if you know how much is absorbed by the body.
The bioavailability is calcium aspartate is 85%. Its molecular formula is [C4H6NO2]2Ca, and molecular weight 304. The calcium availability is therefore 40*100/304 = 13.16%. If 85% is absorbed, then 1000g provides 80% of 13.16 x 10 = 115.6g. The aspartate therefore wins it.
Amino acid Chelates can also be used as a source of calcium, and its bioavailability is improved tremendously by including vitamin D and magnesium in the supplement. The bioavailability of these calcium Chelates are not quoted, but is claimed to be high. Whether or not it is as high as the aspartame is debatable, though it is claimed to be.
Calcium is a very important mineral for human health, and there are several different supplements that can be used. The bioavailability of the calcium is different in each supplement, though the organic forms, calcium aspartate and amino acid calcium Chelates appear to be the highest. When looking for a calcium supplement look for one with additional minerals added as mentioned above to help improve absorption and usability by the body.
Which Calcium is Best?
October 17, 2006 03:52 PM
Customers walking into a health food store today are faced with a vast array of calcium supplements. They might ask: which one should I pick? Which one is best? Not easy questions to answer. All calcium forms will accomplish the same task: providing your body with a nutrient that it needs to build healthy bones and teeth; however, which form of calcium has the features that you want in a calcium supplement? Looking at shelves of calcium products is kind of like shopping for a car; there are many makes and many models—some are basic and others are more sophisticated.
Fortunately, there are many forms of calcium to satisfy your needs. Like the car lot, a health food store offers many options; therefore, you have to select a calcium product that consumers will feel confident in taking regularly and that will provide the most benefit.
Some consumers have done research and will come armed with information. They have already made choices based on advertising, word-of-mouth or an article they have read. They already know the form of calcium they want, be it a “Ferrari” or a “Ford.” If the client doesn’t have a specific preference: asking these basic questions will help in the selection process:
1. Do you prefer tablets, capsules, softgels, liquid or powder?
2. Do you have high or low stomach acid?
3. Do you have absorption issues?
What is calcium?
Calcium (Ca) is one of the most important minerals found in our bones and teeth—99 percent of body calcium is found there. But the calcium molecule does not like to travel alone and, in its more basic state, it comes bounded to carbon (C), Oxygen (O), and/or hydrogen (H) molecules or in more complex form, it is bonded to organic or amino acids that act as stabilizing carriers. On most labels, the amount of calcium listed actually indicates the pure or elemental calcium because it is that amount of the calcium that is deemed important to our daily supplementation, not the complex of the materials with which it is bonded.
Where does calcium come from?
Other than the calcium found in bone, the only natural form of calcium found in nature is calcium carbonate, a calcium molecule bonded to one molecule of carbon and three molecules of oxygen (CaCO3). One of the most common minerals on the face of the earth, calcium carbonate is called calcite, aragonite or vaterite by geologists. In its geological form, it constitutes approximately four percent, by weight, or the earth’s crust.
Commercial sources of calcium carbonate used to make supplements are: limestone, dolomite, oyster cell, egg shell, coral and sea water (have you ever seen that white deposit left by hard water? That’s mostly calcium carbonate). Calcium carbonate is the starting material for all other forms of calcium supplements. From this starting material, calcium can be reduced to more concentrated forms, such as oxide or hydroxide or it can be chelated (bonded) to organic acids and amino acids to help support enhanced absorption.
Lets look more closely at the different forms of calcium that are available as supplements.
Calcium Oxide (CaO): this form is 71 percent elemental calcium and is also called “lime” commercially. This is one of the oldest and most inexpensive forms of calcium used in a variety of commercial applications and it is occasionally used in supplements where space and price are a factor. It sometimes can be found in inexpensive mass market calcium/mineral combinations or multivitamin/mineral products and in a unique algal calcium from Japan. Unfortunately, CaO is a strong alkali that may cause stomach distress, which is why it isn’t often used in health food supplements.
Calcium Hydroxide (CaHO): at 54 percent elemental calcium, it is the next highest source of elemental calcium and is also known commercially as “slaked lime.” It is used where space is an issue. Although it is also a strong alkali, it is more stable than calcium oxide. It is most often used as a component of multi-mineral formulations or in addition to other forms of calcium (i.e., calcium citrate) to provide potency where space is an issue. It is not often used as a single ingredient in health food supplementation. This is for people who want a high dosage of calcium from a minimum amount of pills in multi-mineral formulas.
Calcium Carbonate (CaCO3): at 40 percent elemental calcium, it is the most widely used form of calcium in single ingredient calcium supplements as well as combination supplements. Inexpensive and an abundant source of elemental calcium, it is the only form of calcium found in nature outside of bone. It is the primary form of calcium used in the mass market and in antacid products. This is for people who have high stomach acid and who need a buffering type of calcium. Also for people who want a high dose of calcium in a minimum amount of pills.
Calcium Citrate: at 21 percent elemental calcium, it is one of the most popular forms of calcium supplements in the health food market as well as the mass market. This calcium salt does not lower stomach acid as much as calcium carbonate. This calcium salt is usually recommended for people who have low stomach acid, have had stomach surgery or who need a form of calcium that will not lower their stomach acid further.
Calcium Gluconate and Lactate: these two forms of calcium are high soluble. Since the amount of elemental calcium is much lower (9 percent and 13 percent respectively), they are used more often in powder form and mixed with liquids or food. When mixed in a beverage, the calcium is already dissolved and is ready to be absorbed. This is the best calcium salt for people who have overactive bowels, who have trouble swallowing pills or who don’t like the taste of pre-formed liquid calcium supplements. These calcium powders can be mixed in juices or smoothies or added to food as they are virtually tasteless.
Calcium Orotate and Asporotate: In the mid 20th century, Dr. Hans Nieper, a German scientist, advanced a theory that orotic and aspartic salt forms of calcium are transported directly to cell membranes for better absorption. The Solaray brand developed an asporotate formula, which combines three organic acids: aspartic acid (-Asp), orotic acid (-oro) and citric acid (-tate) into one product. The asporotate formula has become one of the most popular calcium formulas and is exclusive to the Solaray brand. This product is for customers who appreciate the idea of combining the enhanced absorbability of three organic acids into one. Aspartate and citrate are also part of the krebs (energy) cycle and are natural to the body’s metabolic systems and, according to Neiper, calcium Orotate and Aspartate are mineral transporters that enter into the cells to facilitate enzymatic actions rather than being extra-cellular. For people who believe that intracellular calcium is of importance, calcium Orotate and asporotate may be good choice.
Calcium Hydroxyapatite: this is another “natural form of calcium usually as a mineral ash form bovine source bone. Bone meal is also a form of calcium from bovine bone. These forms of animal derived calcium are for customers who want a source that is closest to their own bone matrix. Not for vegetarians.
Calcium Amino Acid Chelates (*HVP): this form is calcium carbonate bonded (Chelated) to a form of amino acid complex such as whole rice concentrate or other grain source. This form is for customers who want the additional bioavailability of amino acids.
Calcium AEP: Another form of calcium endorsed by Dr. Hans Nieper who theorized that calcium would cross the cell membranes more readily when it was combined with phosphatidyl ethanolamine or Amino Ethanol Phosphate (AEP), a nutrient found in nerve sheaths. This highly specialized form is for very educated customers who are proponets of Hans Niepers theory.
So, which form is best?
Calcium, like cars, comes in a variety of forms. Isn’t it wonderful that we have so many choices? The point is, there is no best one, there are only individual choices. Although we have our favorites, taking a calcium supplement, regardless of which one it is, should:
Our primary concern when choosing a calcium supplement should be to provide our body with the right amount of calcium daily so that our skeleton and teeth can maintain proper mineralization and strength as the cells continuously break down and rebuild. The type of calcium complex we prefer is entirely up to us.

Magnesium is a dietary mineral with a wide array of biological activities in the body. Magnesium participates in numerous life-essential processes that occur both inside and outside cells. Magnesium deficiency impacts normal physiologic function on many levels. Adequate magnesium is a fundamental requirement for optimum function of the cardiovascular system, the nervous system and skeletal muscle, as well as the uterus and GI tract. Magnesium deficiency can affect health of the heart, bones and blood vessels and alter blood sugar balance .
Magnesium–Important for Everyone, Deficient in Many The average person living in a modern country today very likely consumes less than the optimum amount of magnesium . An abundance of data collected over the last two decades shows a consistent pattern of low magnesium intake in the U.S. This pattern cuts a wide swath across various age-sex groups. The USDA’s Nationwide Food Consumption Survey found that a majority of Americans consumed less than the recommended daily magnesium intake . Twelve age-sex groups were studied and this low magnesium intake was true for all groups except 0 to 5 year olds.
An analysis of the nutrient content of the diets of 7,810 individuals age four and above included magnesium among several nutrients where the amounts supplied by the average diet "were not sufficient to meet recommended standards" . The FDA’s Total Diet study examined the intakes of eleven minerals, including magnesium, among eight age-sex groups. Data was collected four times yearly from 1982 to 1984. Levels of magnesium, calcium, iron, zinc and copper were low for most age-sex groups . Surveys conducted in Europe and in other parts of North America paint a similar picture. Loss of magnesium during food processing is one explanation for this global lack of adequate dietary magnesium .
In particular, the elderly may be susceptible to magnesium deficiency for a variety of reasons, including inadequate magnesium intake, poor absorption due to impaired gastrointestinal function and use of drugs such as diuretics that deplete magnesium from the body . It has recently been theorized that magnesium deficiency may contribute to accelerated aging, through effects on the cardiovascular and nervous systems, as well as muscles and the kidneys .
Women who take both synthetic estrogen and calcium supplements may be at risk for low blood levels of magnesium . Estrogen promotes the transfer of magnesium from blood to soft–tissues. Low blood magnesium may result if the ratio of calcium to magnesium intake exceeds 4 to 1. Magnesium supplementation is thus advisable for women taking estrogen and calcium.
Young adults are not immune to magnesium deficiency. The University of California’s Bogalusa Heart Study collected nutritional data from a cross-sectional sample of 504 young adults between age 19 and 28 . The reported intake of magnesium, along with several other minerals and vitamins, was below the RDA.
Glycine is a highly effective mineral chelator. This is because it is a low-molecular-weight amino acid, hence is easily transported across the intestinal membrane. A study conducted at Weber State University found this particular magnesium glycinate was absorbed up to four times more effectively than typical magnesium supplements.
Magnesium-the Versatile Mineral
The average adult body contains anywhere from about 21 to 28 grams of magnesium. Approximately 60 percent of the body’s magnesium supply is stored in bone. Soft tissue, such as skeletal muscle, contains 38%, leaving only about 1 to 2% of the total body magnesium content in blood plasma and red blood cells. Magnesium in the body may be bound either to proteins or "anions" (negatively charged substances.) About 55% of the body’s magnesium content is in the "ionic" form, which means it carries an electrical charge. Magnesium ions are "cations," ions that carry a positive charge. In its charged state, magnesium functions as one of the mineral "electrolytes."
Magnesium works as a "co-factor" for over 300 enzymatic reactions in the body. Metabolism uses a phosphate containing molecule called "ATP" as its energy source. Magnesium is required for all reactions involving ATP . ATP supplies the energy for physical activity, by releasing energy stored in "phosphate bonds".
Skeletal and heart muscle use up large amounts of ATP. The energy for muscle contraction is released when one of ATP’s phosphate bonds is broken, in a reaction that produces ADP. Phosphate is added back to ADP, re-forming ATP. ATP also powers the cellular "calcium pump" which allows muscle cells to relax. Because it participates in these ATP-controlled processes, magnesium is vitally important for muscle contraction and relaxation. By controlling the flow of sodium, potassium and calcium in and out of cells, magnesium regulates the function of nerves as well as muscles .
Magnesium’s importance for heart health is widely recognized. The heart is the only muscle in the body that generates its own electrical impulses. Through its influence on the heart’s electrical conduction system, magnesium is essential for maintenance of a smooth, regular heartbeat . Magnesium appears to help the heart resist the effects of systemic stress. Magnesium deficiency aggravates cardiac damage due to acute systemic stress (such as caused by infection or trauma), while magnesium supplementation protects the heart against stress . This has been found true even in the absence of an actual magnesium deficit in the body.
Evidence suggests that magnesium may help support mineral bone density in elderly women. In a two-year open, controlled trial, 22 out of a group of 31 postmenopausal women who took daily magnesium supplements showed gains in bone density. A control group of 23 women who declined taking the supplements had decreases in bone density . The dietary intakes of magnesium, potassium, fruit and vegetables are associated with increased bone density in elderly women and men . In an interesting animal study, rats were fed diets with either high or low levels of magnesium. Compared to the high magnesium-fed rats, bone strength and magnesium content of bone decreased in the low-magnesium rats, even though these rats showed no visible signs of magnesium deficiency . While this finding may or may not apply to humans, it raises the possibility that diets supplying low magnesium intakes may contribute to weakening of bone in the elderly.
Maximizing Absorption––Chelated Minerals Explained Mineral absorption occurs mainly in the small intestine. Like any mineral, magnesium may be absorbed as an "ion," a mineral in its elemental state that carries an electric charge. Mineral ions cross the intestinal membrane either through "active transport" by a protein carrier imbedded in the cells lining the membrane inner wall, or by simple diffusion. The magnesium in mineral salts is absorbed in ionic form. However, absorption of ionic minerals can be compromised by any number of factors, including: 1) Low solubility of the starting salt, which inhibits release of the mineral ion, and 2) Binding of the released ion to naturally occurring dietary factors such as phytates, fats and other minerals that form indigestible mineral complexes .
A second absorption mechanism has been discovered for minerals. Experiments have shown that minerals chemically bonded to amino acids (building blocks of protein) are absorbed differently from mineral ions. This has given rise to the introduction of "chelated" minerals as dietary supplements. Mineral amino acid Chelates consist of a single atom of elemental mineral that is surrounded by two or more amino acid molecules in a stable, ring-like structure.
Unlike mineral salts, which must be digested by stomach acid before the desired mineral portion can be released and absorbed, mineral Chelates are not broken down in the stomach or intestines. Instead, Chelates cross the intestinal wall intact, carrying the mineral tightly bound and hidden within the amino acid ring. The mineral is then released into the bloodstream for use by the body. Research by pioneers in the field of mineral chelation and human nutrition indicates that the best-absorbed Chelates consist of one mineral atom chelated with two amino acids. This form of chelate is called a "di-peptide." Compared to other Chelates, di-peptides have the ideal chemical attributes for optimum absorption . Dipeptide Chelates demonstrate superior absorption compared to mineral salts. For example, a magnesium di-peptide chelate was shown to be four times better absorbed than magnesium oxide .
Consumer Alert! Not all "amino acid Chelates" are true Chelates. In order for a mineral supplement to qualify as a genuine chelate, it must be carefully processed to ensure the mineral is chemically bonded to the amino acids in a stable molecule with the right characteristics. The magnesium bis-glycinate/lysinate in High Absorption Magnesium is a genuine di-peptide chelate ("bis" means "two"). It has a molecular weight of 324 daltons, considerably lower than the upper limit of 800 daltons stated in the definition of "mineral amino acid Chelates" adopted by the National Nutritional Foods Association in 1996 .
Bioperine® For Enhanced Absorption Bioperine® is a natural extract derived from black pepper that increases nutrient absorption.* Preliminary trials on humans have shown significant increases in the absorption of nutrients consumed along with Bioperine® .

Quercetin and Bromelain - for better health.
July 04, 2005 10:28 AM
Down-regulates the Body’s Response to Environmental Challenges Quercetin is a member of the flavonoid family, a diverse group of low molecular-weight compounds found throughout the plant kingdom. Flavonoids exhibit numerous biological activities, many of which are directly beneficial to human health. Quercetin, which belongs to the “flavonol” subgroup, is one of the most versatile and important flavonoids. Quercetin has a broad range of activity, much of which stems from its interaction with calmodulin, a calcium-regulatory protein.1 Calmodulin transports calcium ions across cellular membranes, initiating numerous cellular processes. Quercetin appears to act as a calmodulin antagonist.1 Through this mechanism, quercetin functions at the cell-membrane level with a membrane-stabilizing action.2 Quercetin inhibits calmodulin-dependent enzymes present at cell membranes such as ATPases and phospholipase, thereby influencing membrane permeability.3 Quercetin affects other calmodulin-dependent enzymes that control various cellular functions, including the secretion of histamine from mast cells.4 A number of investigations have corroborated quercetin’s ability to reduce histamine secretion from mast cells in various tissues, and also from basophils.5,6,7,8,9,10
Quercetin modifies the body’s response to antigenic substances.* Suppression of histamine secretion from mast cells is one of quercetin’s most clinically important effects. Quercetin acts on ATPase at the membranes of histamine-containing granules in mast cells.3 Mast-cell degranulation and subsequent release of histamine into the bloodstream is an integral part of the body’s response to environmental challenges.
Quercetin’s enzyme-inhibiting action extends to enzymes such as phospholipase, which catalyzes the release of arachidonic acid from phospholipids stored in cell membranes.4,10 Arachidonic acid serves as the key substrate for substances such as thromboxanes, inflammatory prostaglandins and leukotrienes. In addition, quercetin inhibits the enzymes cyclooxygenase and lipoxygenase, which catalyze the conversion of arachidonic acid into its metabolites.4,10,11,12 Reducing levels of these metabolites, as well as histamine levels, is beneficial in maintaining the normal comfort level of body tissues and structures.
Quercetin has also been shown to limit the function of adhesion molecules on endothelial cells.13 Adhesion molecules are involved in physiologic processes that influence tissue comfort.13
Bromelain is a complex substance derived from the pineapple stem largely composed of proteolytic (protein-digesting) enzymes. Bromelain acts by a variety of mechanisms to help maintain tissues in a normal state of comfort.14,15 Several investigators, including Taussig16 and Ako, et. al.,17 have presented evidence that bromelain is a fibrinolytic agent, i.e., it induces the breakdown of fibrin, a plasma protein that blocks tissue drainage. The generally accepted mechanisms involve direct proteolysis of fibrin by bromelain and activation of plasmin, a serum protease.16 Plasmin acts on fibrinogen (the precursor to fibrin), forming peptides which stimulate PGE1, a prostaglandin that helps maintain tissue comfort.16
Helps Maintain Health of Blood Vessels by Modifying Oxidation of LDL Cholesterol* — Quercetin’s Antioxidant Action Quercetin is a versatile and effective antioxidant that scavenges a variety of free-radicals such as hydroxyl and lipid peroxy radicals.18 Quercetin also Chelates ions of transition metals such as iron, which can initiate formation of oxygen free radicals.18 LDL cholesterol is vulnerable to oxidation by lipid peroxides. Oxidized LDL is absorbed by macrophages and arterial endothelial cells, leading to the formation of “foam cells,” and eventually plaque deposits, in arterial walls. Quercetin has been shown to protect LDL from oxidation, both by lipid peroxides and transition metal ions.19
Quercetin inhibits blood platelet aggregation (clumping), by potentiating PGI2, an anti-aggregatory prostaglandin, and by raising platelet cyclic AMP levels.20 Human studies have revealed that bromelain also reduces platelet aggregation.21 These properties qualify both quercetin and bromelain as valuable dietary ingredients for maintaining cardiovascular health.*
In addition to the actions described above that support the effects of quercetin, bromelain may also assist the absorption of quercetin in the G.I. tract. (Quercetin is generally believed to be poorly absorbed, although a recent study by Hollman et. al.,22 which concluded that humans do in fact absorb appreciable amounts of quercetin, contradicts this assumption.) Studies have shown that bromelain enhances absorption of antibiotics, presumably by increasing permeability of the gut wall.23, 24 Given that quercetin is a low molecular-weight compound, it is plausible that simultaneously ingested bromelain likewise enhances quercetin absorption.

Modified Citrus Pectin (MCP)...
June 21, 2005 05:21 PM
By Isaac Eliaz, M.D.
Modified citrus pectin (MCP) is an essential nutrient for cancer prevention and treatment. It directly attacks cancer, thereby reducing the disease, but also has properties that enhance overall health. A true super nutrient! Let me explain how it can do all this.
Characteristics of Cancer Cells
Cancer cells are different from normal cells in a number of ways. One difference is they way they "look." All cells have a variety of molecules on their surface, which allow them to communicate with each other and their environment:
Cancer cells have odd amounts or unusual molecular markers on their surface, which allow white blood cells to recognize the cells as cancerous and kill them. One type of molecule cancer cells have in excess is galectin-3. Galectin-3 molecules function as "hands" and help cancer spread. First, they are important in reaching out and stimulating growth of new blood vessels; this allows the cancer to obtain the blood flow and nutrients it needs to grow out of control. Second, galectins allow cells that break off from the primary tumor to clump together in the blood stream, enabling them to move to new sites. Third, the galectin hand can grab hold of the new location and complete the metastasis, or spread, of the cancer.
MCP Blocks the Spread and Growth of Cancer Cells
Modified citrus pectin is a natural substance that can bind to galectin molecules and block their spread and growth. Early research on prostate cancer showed that oral administration of MCP to rodents resulted in a dramatic reduction in prostate cancer metastasis to the lungs. More recent research by the same scientists extended MCP protection to breast and colon cancer, and showed that MCP blocks primary tumor growth and formation of new blood vessels.
Successful Clinical Trial
A commercially available form of modified citrus pectin was developed in response to the positive animal studies and tested in men with prostate cancer. A pilot trial using MCP at 15 grams a day and a subsequent phase II trial both showed that MCP slows prostate cancer progression, as evidenced by a reduction in the rate of PSA rise. PSA (prostate-specific antigen) is a protein made by the prostate gland; elevated PSA blood levels may indicate prostate cancer. The phase II trial, published in Prostate Cancer and Prostatic Diseases (Dec 2003), involved men who at first experienced successful primary conventional treatment; subsequently their PSA again began to climb, representing cancer recurrence. Seventy percent of these men showed a significant reduction in the rise of their PSA climb! Because of the mechanism of action, it is expected people with other cancers (leukemia, breast, colon, lung, nasopharyngeal, brain, lymphoma, melanoma and others that express galectin molecules) also would benefit from MCP.
MCP Chelates and Removes Toxic Metals
Heavy metals, in conjunction with environmental toxins and xenoestrogens, constitute a dangerous insult to the body through DNA damage, hormonal modulation, immune suppression, oxidative stress, and hyper inflammation. The metal chelation properties of MCP (Eliaz, U.S. patent #6,462,029) have been confirmed in a recent pilot trial. In healthy individuals, MCP increased urinary excretion of the toxic metals mercury, cadmium, arsenic and lead. In addition, longterm administration of MCP has been shown to reduce the body burden of heavy metals such as mercury, arsenic, lead, and nickel. MCP's ability to remove heavy metals and environmental toxins on an ongoing basis may significantly benefit people with cancer and other diseases involving immune dysfunction.
Clinically Validated MCP
Only one form of MCP has been validated in human clinical trials. This is important since no other MCP on the market matches the chemical specifications of the clinically validated product. If the molecular weight of MCP is too high it can't be absorbed into the bloodstream. If it is too low it won't effectively block galectin sites. Another property, the degree of esterification, must be below 5% for optimal binding. The most effective specifications were defined by cell culture studies and remain a trade secret. If you want the effects seen in the clinical studies, you must take the preparation used in those studies, at the recommended dose of 15grams/day.
The Use of Modified Citrus Pectin
MCP Application Use (Take on an empty stomach) Active Cancer 15 grams/day (5 grams, three times a day) Biopsy 15 grams/day (5 grams, three times a day) Take one week before procedure and two weeks after. Heavy Metal Chelation High body burden levels: 15 grams/day (5 grams, three times a day) Lower levels: 15 grams/day for 5 days a month, 5 grams/day the rest of the month Cancer Prevention 5 grams/day ongoing

Two billion people, including one in 10 American women, are lacking iron. Here's how veggies and other foods can supply you with enough of this vital mineral.
Back in the days of black and white television, a popular commercial cautioned viewers about the dangers of iron-poor blood. While those ads trumpeting the debilitating fatigue of iron deficiency have disappeared from our colorized video world, medical researchers now recognize that many of us, in fact, are hampered by an iron shortage. What those old ads missed: a lack of iron can slow you down mentally and physically even before it shows up in your blood.
A Woman's Dilemma: Hidden Deficiencies Experts estimate that one in 10 American women are low in iron but many haven't become so deficient that they are aware of their shortage. In other countries, up to eight in 10 women run short on iron. While researchers once believed that iron deficiency was only serious if it was drastic enough to cause anemia (what used to be called "tired blood"), studies now show that even mild deficiencies can compromise health.
Worldwide, public health experts believe that the lives of about 2 billion people are affected by iron deficiency. Most of these people are women, who lose blood on a monthly basis during their childbearing years. Men are generally not low in iron. Iron is necessary for the formation of red blood cells-particularly the creation of hemoglobin, the reddish pigment in these cells that enables them to deliver oxygen to muscles and other bodily tissues. If you are very low in iron, the resulting anemia leaves you feeling fatigued.
Your body stashes iron not only in your blood cells, but in your liver and other tissues as well. When you don't consume enough iron, first your liver stores decrease, then your tissue supplies disappear and, finally, your blood runs low and you develop anemia. Early on in the iron-depletion process, a low iron count won't make your daily activities more difficult. Cornell University researchers found, in experiments on women who were mildly depleted, that taking or not taking iron supplements had no effect on how these women felt while exercising.
" Supplementation makes no difference in exercise-training improvements in women with low iron storage who are not yet tissue-iron deficient or anemic," says Thomas Brownlie, one of the Cornell researchers.
Supplementing Your Supply
Even in the beginning stages of iron deficiency, however, experts still believe you should take supplements: an uncorrected iron shortage can mean serious problems lurk ahead (American Journal of Clinical Nutrition 5/04). For that reason, the next time you visit your healthcare practitioner you should request a serum transferrin receptor concentration test, which can detect an early iron shortage. (Don't start taking iron supplements without consulting a knowledgeable medical professional.)
" It would be useful for women who test low for iron but who are not yet anemic to have this test," notes Cornell's Brownlie. "Women found to be tissue-iron deficient will find exercise exceedingly difficult without improving their iron status-which could be achieved by increasing consumption of iron-rich foods or iron supplementation."
If you let your iron levels run down so low that it shows up as anemia, not only will you be tired but your thinking may be fogged as well. " Millions of women who are mildly iron deficient must work harder than necessary when exercising or working physically, and they can't reap the benefits of endurance training very easily," says Jere Haas, PhD, one of the researchers involved in these studies and a nutrition professor at Cornell. "As a result, exercise is more difficult so these women are more apt to lose their motivation to exercise."
Meanwhile, researchers at Wake Forest University in North Carolina report that, as you age, anemia can make you more vulnerable to disabilities while weakening your muscles and draining your strength (Journal of the American Geriatric Society 5/04). That type of anemia may be linked to shortages of both iron and vitamin B12.
" Our results suggest that anemia is a risk factor for disability, poor physical function and low muscle strength-all which can threaten the independence of older adults," says Brenda Penninx, PhD, lead researcher. If you are a woman who exercises frequently, cuts calories to lose weight or eats a mostly vegetarian diet, watch out-you may be at high risk for iron depletion.
To steer clear of iron shortages, the Cornell researchers recommend eating lean red meat. If you are a vegetarian, taking vitamin C with meals improves your iron absorption from iron-rich foods like peanuts, whole wheat, brown rice and leafy green vegetables, as does using iron cookware.
When it comes to absorbing supplemental minerals like iron, not all minerals may be created equal. In particular, minerals that are in chelated form are generally believed to be absorbed more efficiently in your digestive system. The word "chelate" comes from the Greek word for claw. Chelated minerals are chemically implanted into proteins known as peptides. This bound molecular structure mirrors the way minerals are contained in natural whole foods, which have been found to contain their own natural Chelates.
Chelated minerals are more well-suited to your digestive tract. A key advantage of chelated formulations is their stability after you swallow them. Many other forms of supplemental minerals-which are often combined with inorganic salts or organic acids-may be broken down prematurely in the digestive tract, leading to poor absorption and a stomachache.
Chelates, however, maintain their structure sufficiently to reach the spot in the digestive tract where they are most efficiently taken into the bloodstream. Once there, the body's digestive enzymes dismember the proteins and convert the minerals into absorbable form.
Getting enough iron and other minerals is not that difficult a task-it's just one that is too often overlooked. But if you pride yourself on your iron will or iron constitution, or just seek to iron out a few of the kinks in your health, you may need to significantly pump up your iron.
Minerals - Why take them?

Minerals, along with vitamins, amino acids and essential fatty acids, are one of the fundamental tiers of nutritional supplementation. Many essential minerals have been depleted from our soils due to modern farming practices, making mineral supplementation more critical than ever in today's world. Minerals are perhaps more susceptible to issues of bioavailability and absorption than any other class of nutrients. For this reason, Source Naturals has devoted a great deal of research to providing more bioavailable, absorbable forms of key nutritive minerals.
MINERALS: A MULTITUDE OF FUNCTIONS
Life on Earth began in the sea. Most scientists now believe that the ancient ocean was a 'primordial soup' of organic chemicals which contained all the necessary ingredients - amino acids, sugars, and nucleotide components, floating in a solution of water and minerals; for life to get started. Millions of years later, when the first creature crawled up on dry land, evolution had contrived a way for it to carry the ancient ocean along with it.
The composition of the fluid that bathes your cells and tissues is believed to be substantially the same as the ocean some 2 billion years ago. The body is extremely particular about the balance of dissolved minerals in this fluid&endash;so particular that it will sometimes sacrifice its own structure to maintain proper mineral balance in the fluids. For example, one mechanism for the homeostatic control of plasma calcium concentration is the flux of calcium into and out of the bones. If plasma calcium remains too low for extended periods the calcium reserve of the bones could be depleted. What functions do minerals serve, and why are they so important?
Aside from providing structure through the bones and teeth, one of the most important roles of minerals is that of electrolytes. The membranes of our cells are flexible and freely permeable to water. The interior of a cell contains an abundance of large and small organic molecules, most of which have an electric charge. These charged molecules will attract inorganic charged molecules called electrolytes, such as sodium and potassium, crowding water out of the cell interior. If the cell did nothing to counteract this phenomenon, the difference in water concentration across the cell membrane would cause more and more water to move into the cell by osmosis, eventually causing the cell to swell up and burst.
Minerals act as cofactors in over a thousand different reactions in the human body; magnesium alone is necessary for the functioning of over 300 enzymes.
A proper balance of minerals is essential to optimal health and vitality. Not only are they a crucial component of the internal environment and structure of the body, they are crucial to the enzymatic reactions that create energy, build tissues and protect the body. Minerals, unfortunately, are also one of the first casualties of the processed food revolution. Thanks to decades of "progress" in industrial farming methods, super-fertilizers and other methods have been developed for growing vegetables and grains that travel well and look healthy and pretty, but are depleted of much of the nutrient complexity required to optimally support human life. Many of the minerals that are left are stripped out when these grains and vegetables are processed to make packaged foods. These 'foods' are often preserved with chemical additives and fillers that can make the minerals they still contain impossible to digest.
What all this adds up to is the fact that mineral supplementation is extremely important. It is also important to ensure that the supplements you take are in forms that are absorbable and bioavailable. Unfortunately, there is no simple formula to follow in this regard, for the process of mineral absorption is complex and can be enhanced or hindered by a variety of factors. There is a great deal yet to be discovered about this aspect of human digestion and nutrition.
Because of the complexity of mineral metabolism Source Naturals offers a full series of major minerals and trace minerals in a variety of high quality, bioavailable forms to meet individual needs. In some cases we have gone further, basing our formulations on a knowledge of biochemical principles. For example, the absorption of many minerals seems to be enhanced by the presence of amino acids. Therefore, we offer amino acid Chelates, minerals which are specially chelated (bound) with amino acids from hydrolyzed vegetable protein. In addition, we provide Krebs cycle Chelates, minerals which are organically bound to metabolites of the body's cellular energy generation cycle.
