Did you know that glutathione is not only great for liver health, but it also promotes beautiful, radiant skin?Glutathione (GSH), often considered as an amino acid but actually a tripeptide, is an antioxidant primarily synthesized in the liver. Composed of cysteine, glutamic acid, and glycine, it plays a crucial role in the synthesis and repair of DNA and protein, as well as the synthesis of prostaglandins. With its involvement in various functions like amino acid transport, toxin and carcinogen metabolism, immune system function, prevention of oxidative cell damage, and activation of enzymes, it is undoubtedly the most important tripeptide in the body. While the benefits of supplementing with glutathione are numerous, two particularly compelling reasons are its positive impact on liver health and beautiful skin, which are the key focus of this article. However, before diving into the specifics of liver health and skin benefits, it's important to review the data on glutathione depletion and absorption. GSH depletion can occur due to various oxidative stressors such as radiation, v.infections, enviro toxins, household chemicals, heavy metals, surgery, inflammation, burns, septic shock, and dietary deficiencies of GSH precursors and enzyme cofactors. Additionally, research suggests that GSH levels tend to decline with age. The bioavailability of glutathione as a dietary supplement has encountered challenges in the past. Studies in the 1990s suggested that oral GSH might be inactivated by peptidases in the gut, as the levels of glutathione in the body did not seem to correlate with dietary intake, despite its presence in fruits, vegetables, and meats. Moreover, previous studies showed no significant increase in blood GSH levels when subjects were given high doses of 1,000-3,000 mg. As a result, alternative strategies like supplementation with NAC were used to boost GSH levels. In 2014, something interesting happened that changed the way we look at the bioavailability of GSH. A groundbreaking study published in the Journal of Agricultural and Food Chemistry shed new light on the old research. This study showed that GSH, when taken in its intact form as OPITAC, a yeast-derived glutathione by Kohjin/Mitsubishi, can actually be rapidly transported across intestinal epithelial cells. Once inside, it gets rapidly converted into oxidized glutathione (GSSG) and accumulates in red blood cells and the liver, with only a small presence in plasma. So, although the GSH was indeed absorbed, it didn't show up in blood plasma because it transformed into GSSG and stored in the red blood cells and the liver. The bottom line is, supplementing with GSH is an effective way to boost GSH levels in the body. This finding was further confirmed in another study that described how OPITAC, as a yeast-derived glutathione by Kohjin/Mitsubishi, is directly absorbed in its electrochemically reduced form in the intestine, then transported in the blood in bound forms, and eventually deposited into the liver in its reduced form. But here's where it gets even more significant. A six-month randomized, double-blinded, placebo-controlled trial involving 54 adults was conducted to investigate the effects of oral GSH supplementation (250 or 1,000 mg/day, as OPITAC glutathione, Kohjin/Mitsubishi) on GSH levels in various parts of the body, including blood, erythrocytes, plasma, lymphocytes, and exfoliated buccal mucosal cells. The results were astounding. After one, three, and six months, GSH levels in blood increased significantly compared to baseline in both dosage groups. At the six-month mark, GSH levels skyrocketed 30-35 percent in erythrocytes, plasma, and lymphocytes, and a mind-boggling 260 percent in buccal cells in the 1,000 mg group (P < 0.05). Even in the low-dose group, GSH levels in blood and erythrocytes increased by 17 and 29 percent, respectively (P < 0.05). This research clearly demonstrates that supplementation with GSH is not only effective for increasing GSH levels in the body but also for maintaining them. So, to sum it all up, the evidence speaks volumes - supplementing with GSH can have a profound impact on your body's GSH levels, and trust me, that's definitely a good thing! Liver HealthWhen it comes to our well-being, the liver is a true superhero. Let's dive into some fascinating details about this essential organ. Did you know that the liver is not only the largest reservoir of GSH (glutathione) but also a major site of GSH manufacture in the body? Pretty impressive, right? Special cells in the liver work tirelessly to synthesize GSH, which plays a crucial role in detoxification. Speaking of detoxification, the liver is a champion in this field. Its cells have sophisticated mechanisms to break down toxic substances, be it internal or external compounds. During the detoxification process, the liver attaches or conjugates the toxins to water-soluble substances. This attachment makes the toxic molecules more water-soluble, less harmful, and easier to eliminate via urine or bile. In fact, glutathione conjugation produces water-soluble mercaptates that are excreted via the kidneys, effectively detoxifying acetaminophen and nicotine. Isn't it amazing how this process helps our bodies get rid of harmful substances? But that's not all. Adequate levels of glutathione are crucial for the elimination of fat-soluble compounds, particularly heavy metals like mercury and lead. What's more, GSH serves as a cofactor for various peroxidase enzymes, aiding in the detoxification of peroxides generated from oxygen radical attacks on biological molecules. It also assists transhydrogenase enzymes in reducing oxidized centers on DNA, proteins, and other biomolecules. Talk about a multitasker! The practical significance of this liver superhero was demonstrated in a study involving workers exposed to lead. A group of five workers received GSH at 200 mg/day for 30 days, while five others served as the control group. The results were striking. The group receiving GSH showed a significant increase in ALA dehydratase activity (which is inhibited by lead) compared to the control group (p < 0.05). This indicates that GSH could be a valuable solution for treating patients with lead poisoning. So, let's take a moment to appreciate the remarkable liver and its incredible role in maintaining our health and well-being! Alcohol IntoxicationAlcohol consumption is widely recognized for its capability to induce hepatic steatosis, also known as fatty liver disease, and disrupt biomembranes due to hepatic lipid peroxidation. This can lead to various lifestyle-related diseases and even hepatic cirrhosis by diminishing hepatic physiological function. Nevertheless, animal studies have shown that hepatic damage caused by alcohol intoxication can be mitigated by glutathione (GSH), a powerful antioxidant found in cells. To further investigate the impact of GSH supplementation on the effects of alcohol intake, a human crossover comparative study was conducted. The study involved twenty healthy men and women who were grouped into three categories: placebo, 100 mg GSH (as OPITAC glutathione, Kohjin/Mitsubishi), and 30 mg curcumin. The study evaluated laboratory parameters, including breath alcohol concentration at different time intervals (20, 60, 120, and 180 minutes post-alcohol consumption) as measured by an alcohol checker. Additionally, subjective feelings were assessed through a questionnaire. During the study, all participants consumed whiskey in a quantity equal to their body weight multiplied by 1.25 mL, and were instructed to drink the entire sample within 10 minutes. The results revealed that the breath alcohol concentration in the group supplemented with GSH significantly decreased compared to the placebo and curcumin groups at 20 (p<0.01), 60 (p<0.01), 120 (p<0.05), and 180 (p<0.08) minutes post-consumption. Furthermore, the GSH group reported lower levels of "sleepiness," "headache," and "upset stomach" in the subjective feeling questionnaire. Importantly, the concentration of aspartate aminotransferase (AST), an indicator of alcohol-induced organ damage, was significantly lower in the GSH group after two months compared to the placebo group. The oral intake of GSH has demonstrated its effectiveness in reducing alcohol consumption-related stress and improving long-term hepatic function. These findings highlight the potential benefits of GSH supplementation in alleviating the detrimental effects of alcohol intoxication on the liver. Nonalcoholic fatty liver diseaseNonalcoholic fatty liver disease (NAFLD) is a condition characterized by the build-up of fat in the liver of individuals who consume little or no alcohol. Unfortunately, NAFLD is quite common, affecting nearly one-third of all American adults. Interestingly, it often presents without readily apparent signs or symptoms, sometimes resulting in complications, and can lead to liver inflammation and scarring as the fat accumulates. Additionally, NAFLD is typically associated with conditions such as insulin resistance, central obesity, reduced glucose tolerance, type-2 diabetes, and elevated triglyceride levels. Recognizing the substantial role glutathione (GSH) plays in phase 2 liver detoxification, a pilot trial was conducted to examine the therapeutic effects of GSH supplementation in patients with NAFLD. The trial included 29 individuals, and the patients were provided with daily oral supplementation of GSH at a dose of 300 mg (in the form of OPITAC glutathione, from Kohjin/Mitsubishi). The patients' clinical parameters were assessed before and after the GSH supplementation, and liver fat and fibrosis were quantified as well. The primary goal of the study was to determine any changes in alanine aminotransferase (ALT) levels. The results indicated a significant decrease in ALT levels following the GSH supplementation. Furthermore, triglycerides, non-esterified fatty acids, and ferritin levels also showed a reduction. This pilot study provides promising evidence for the potential therapeutic effects of oral glutathione administration, even at practical doses, in patients diagnosed with NAFLD. However, further investigation through large-scale clinical trials is necessary to validate its efficacy. In summary, NAFLD is a prevalent condition with potential serious consequences, but studies like the aforementioned pilot trial shed light on potential treatment options such as GSH supplementation. The findings demonstrate the need for continued research in order to provide more conclusive evidence and expand our understanding of NAFLD management. Beautiful SkinBy activating melanocytes in the skin, there is a notable increase in melanin formation, resulting in various blemishes such as freckles, pigmentation, and UV-induced skin spots, commonly known as age spots or liver spots. This is especially prominent after prolonged sun exposure and tanning. Age spots appear when melanin becomes concentrated or "clumped" in areas that have had years of frequent sun exposure. Luckily, there are materials like glutathione that can prevent or improve such pigmentation-related skin conditions. Another aspect to consider is skin pigmentation, wrinkles, and pores. In a study conducted with eight women in their 30s or early 40s, each supplemented with 100 mg/day of GSH (as OPITAC glutathione, Kohjin/Mitsubishi) for two months, their skin conditions were evaluated using the Robo Skin Analyzer. Several parameters were analyzed, including skin brightness, the amount and area of skin pigmentation, number of pores, and number of wrinkles under the eyes. It was observed that all subjects' skin brightness improved when measured on the second day of the study. Additionally, over the course of the two months, both the amount and area of skin pigmentation decreased, leading to an improvement in blemishes and pigmentation. Not only did glutathione exhibit a whitening effect, but it also reduced the number of wrinkles under the eyes and minimized pores. Furthermore, a randomized, double-blind, two-arm, placebo-controlled study was conducted with 60 otherwise healthy medical students. The purpose was to investigate whether supplementing with 500 mg of glutathione daily for four weeks would affect the skin melanin index compared to a placebo. Melanin inDices were measured at six different sites on the body. The results demonstrated that melanin inDices consistently decreased at all six sites in subjects who received glutathione after four weeks. The reductions were statistically significant compared to those who received the placebo at two sites: the right side of the face and the sun-exposed left forearm (p = 0.021 and 0.036, respectively). This improvement was likewise reflected in the reduction of UV spots. Importantly, both glutathione and placebo were well-tolerated. In conclusion, oral administration of glutathione leads to a lightening of skin color in the tested subjects. Skin LighteningSkin lightening is a process that is of interest to many individuals who seek to achieve a more even and radiant complexion. In recent studies, the use of a lozenge containing GSH 500 mg was explored as a means of skin lightening through an open-label, single-arm trial. The focus of this trial was to evaluate the buccal mucosa as a route for GSH administration and its potential in relation to skin lightening. It is worth noting that substances absorbed through the buccal route have the advantage of entering directly into the systemic circulation, effectively bypassing the gastrointestinal tract. The trial involved thirty Filipino females with Fitzpatrick skin types IV or V who received a daily glutathione-containing lozenge for eight weeks. The results from this trial demonstrated a significant decrease in melanin inDices from baseline to endpoint. What is fascinating is that this visible change became evident in as little as two weeks. It is important to highlight that during this trial, there were no recorded serious adverse events, and the laboratory examination findings remained normal. Based on these findings, the researchers concluded that the lozenge containing glutathione was deemed safe and effective in lightening the skin of Filipino women. In addition to the aforementioned buccal route administration, another interesting approach that emerged from the studies is the topical application of GSH. A double-blind randomized clinical trial35 conducted in Yogyakarta, Indonesia, involved 74 healthy Indonesian women, with an average age of 33.3 ± 5.9 years, to explore the potential benefits of topical GSH. The trial subjects received supervised applications of facial wash twice a day, along with day cream containing sunscreen and night cream. The subjects were divided into three groups based on the active ingredients of the tested products, which included GSH (as OPITAC glutathione, Kohjin/Mitsubishi) at concentrations of 0.1 percent and 0.5 percent, and a control group without GSH. Throughout the trial, the effects of the tested products on skin color and pigmentation were measured using colorimetry with Chromameter Minolta for L. Compared to the baseline measurements, there were significant increases in lightness (L) detected as early as week 2 for the group using GSH at 0.1 percent concentration. Interestingly, this increase was significantly higher compared to the group using GSH at the higher concentration of 0.5 percent, as well as the group without GSH. It is important to note that hyperpigmented lesions also showed improvement, particularly in the group using GSH at 0.5 percent concentration, which displayed superiority compared to the other groups at week 8. In conclusion, the skin care products containing GSH at 0.1 percent and 0.5 percent concentrations were found to be effective in lightening facial skin. The findings from these studies shed light on the potential benefits of GSH in achieving skin lightening, either through buccal administration or topical application. It is worth noting that these studies focused on specific populations and more research is necessary to explore its effectiveness and safety across different skin types and ethnicities.

Date:
July 29, 2015 05:11 PM
Stevia is a natural sweetener that originates in South America – Paraguay and Brazil, mostly – with no calories and is remarkably much sweeter than sugar. The stevia plant Stevia Rebaudiana derives its sweetness from steviol glycocides. The extract is then processed for sale in the form of Truvia and PureVia around North America. It is not yet approved as an additive due to possible side effects of male infertility and genetic mutations.
Benefits of Stevia over Sugar
The yeast we hear about being in our bodies is called Candida albicans and it can ferment sugar in the body, causing the candidiasis infection with treatment involving cutting sugar out of your diet. Stevia does not react with the yeast and can also keep your food sweet. Stevia is a safer and healthier option to sugar. It is natural and sweeter than sugar making it a great option to combat obesity and sugar level problems the world is constantly facing.

Date:
September 19, 2008 09:25 AM
Ginkgo biloba, also known as the maidenhair tree, grows naturally in two small areas of Eastern China. It is believed that even these sources are artificial, and planted and maintained by monks over many centuries, and that there are no true natural sources of the tree left. Other than these, all living ginkgo trees are now artificially farmed. The ginkgo seeds contain nuts that are a traditional food in China, served at Chinese New Year, and on other special occasions such as weddings, and is also used in traditional Chinese medicine. The seeds have been used in the treatment of coughs and asthma, and during the late 1970s and 80s, the uses of ginkgo biloba in medicine was extensively investigated with a view to determine the range of conditions that the tree could be used to treat. Given that many ancient Chinese remedies have found to be effective, and with a relevant scientific basis, this was a logical step. It has been established that ginkgo biloba could have three possible effects on the body. These are:
* Improvement in circulation including that in the small capillaries. The last of these has been responsible for many cardiovascular conditions, and disorders of the kidneys, lungs and central nervous system, and is due to the effect of the platelet-activating factor (PAF) that ginkgo appears to inhibit. Before delving deeper into the possible beneficial effects of Ginkgo, let us first examine the active ingredients believed to be involved in the perceived beneficial effects. Ginkgo leaf extract contains terpenoids (bilobalides and ginkgolides) and flavonoid glycosides. Flavones can reduce the fragility of capillaries, and protect the body from blood loss through damaged capillaries, particularly in the brain. The Ginkgolides, particularly ginkgolide B, inhibit the platelet-activating factor and so increase the fluidity of the blood that improves circulation, again particularly in the micro-capillaries of the brain. This is also why it is believed to reduce the incidence of cerebral thrombosis and resultant strokes. The antioxidant effect of ginkgo biloba extract (GBE) has been widely studied, and by scavenging free radicals the extract can help to prevent cell membrane damage, and so prevent cells from being destroyed. It has been established that pretreatment of cells with GBE can prevent such damage in rats. The anti-inflammatory properties of ginkgo biloba, as seen in some asthma patients for example, is thought to be due to the inhibition of the platelet-activating factor (PAF) by ginkgolide B, PAF playing a significant part in the inflammatory response to allergens, and PAF is now believed to be responsible for conditions such as asthma, renal diseases, central nervous system disorders and ischemia, a restriction in the blood supply, particularly to the brain. It follows, therefore, that the effect of GBE on these conditions is likely to be due to PAF inhibition, and a reduction in the inflammatory response to a number of conditions. What evidence is there for this? In fact, results of the trials carried out have been inconclusive one way or the other. Hence, a trial published by the Journal of the American Medical Association reported no effects after a 6 week trial of Ginkgo on Alzheimer’s and memory disorders. However, other trials have indicated positive effects after 6 weeks, and it could be that the GBE has to be taken for more than 6 weeks for any effects to be noticed. It is certainly believed to be a longer term treatment rather than have instant results, although some tests have shown improvement in concentration for up to 2.5 hours after treatment. The bulk of the evidence is favorable on the effect of GBE on memory disorders. Test on rats, in which the blood flow to the brain was mechanically blocked by carotid compression, indicated that ginkgo biloba promoted an increase in the glucose and ATP levels in the brain neurons. Other trials have indicated that neurological damage in mice subjected to neurotoxins was reduced by the administration of GBE, and while not conclusive with respect to humans, the effect of GBE on the brain appears to be more than just opinion. To sum up, ginkgo biloba is believed to be effective in treating the following disorders by virtue of its effect in improving the fluidity of the blood, protecting fragile capillaries from damage, exerting an antioxidant effect on free raDices, and so prevent damage to cell membranes, and its inhibiting effect on platelet-activating factor: Circulation Problems Circulation problems in the arteries can lead to blood clots that in turn cause strokes and cardiac problems. By preventing blood clots through the inhibition of PAF, ginkgolide B can help to maintain a healthy circulation system that also help to maintain circulation in the very small capillaries that feed the brain. Atherosclerosis This is caused by hardening and blockage of the arteries, and one of the effects of ginkgo biloba is to soften the arteries, help to unblock them and to prevent plaque formation by its antioxidant effect on the free radicals that cause the plaque by oxidation of LDL lipids. This is particularly true of the cerebral arteries. Memory Impairment The increased blood flow to the brain that GBE promotes can help to improve memory, although test are indicating that treatment has to continue for 6 weeks or more for it to be effective. Reduced blood flow to the brain is a common cause of memory impairment. Alzheimer’s disease Ginkgo biloba has been used in the treatment of the symptoms of this condition, although it cannot be cured. It is thought that the improved circulation in the brain makes best use of the unaffected brain cells, improving memory and cognitive thought. Reynard’s Disease This is a condition where the extremities fail to warm up after being exposed to cold, and is caused by poor circulation in the small capillaries in which the blood pressure is very low. They symptoms are numbness and pins and needles, and GBE helps to overcome this condition due to improvement in the circulation and protection of the capillaries by rendering them less fragile. Vertigo GBE can help to reduce the symptoms of vertigo such as nausea and dizziness. This is believed, once again, to be due to an improvement in blood circulation.
There are few doubts that ginkgo biloba extract improves the circulation, particularly in the micro-capillaries in the brain and extremities of the body, and also possesses antioxidant properties, both of which help to maintain and improve the memory, and that combined with its effect on the platelet-activating factor, most of the properties of GBE is due to its capacity to maintain and improve circulation, particularly through those blood vessels closest to the blood-brain barrier.

Date:
April 10, 2007 11:57 AM
Supports normal heart function*
A significant amount of in vitro, animal and human research suggests benefits of ribose on heart function.* Studies have shown that ribose supplementation can enhance cardiac energy levels and support cardiovascular metabolism.* Ribose has been shown in clinical trials to enhance the recovery of heart muscle ATP levels and improve myocardial function following exercise.
Studies suggest that ribose supplementation can increase the tolerability of the cardiovascular system to exercise-induced fatigue.1 In one study, twenty men underwent treadmill exercise tests on two consecutive days to confirm the onset of fatigue secondary to exercise. The participants were then randomized to the treatment group or a placebo group. The groups received either four doses of 15 grams of D-ribose (60 grams/day total) or the same amount of placebo each day. After three days of treatment, another treadmill test was performed. The time it took to reach the specified level of fatigue was significantly greater in the ribose group than in the placebo group.
Another study investigated the ability of ribose to support healthy heart function and quality of life.2 In a randomized, crossover design study, fifteen individuals were given 5 grams three times a day of either D-ribose or placebo. Each treatment period lasted three weeks. In patients receiving ribose, echocardiography demonstrated enhancement of heart function, reflecting a “more efficient relaxation phase of the heart”. Participants also had a significant improvement in their subjective quality of life scores compared to placebo.
Scientists suggest that suboptimal heart function is a result of the heart requiring more energy to function properly. Ribose supports the heart’s enhanced energy requirements, promoting optimal heart function. It does so by enhancing the stores of high-energy phosphates in heart tissue. These intermediates are necessary for the production and resynthesis of ATP. A double-blind crossover study in which 12 individuals were randomized to receive either ribose or dextrose (both administered as 5 grams three times daily for three weeks, followed by a 1-week washout period and crossover of treatments for three additional weeks) suggested significant enhancements in normal cardiac function during the period of ribose supplementation.3
Perhaps one of the more useful illustrations of the potential for ribose to support heart function comes from a study in which 20 rats received a continuous infusion of ribose for 24 hours (control rats received an infusion of saline). The hearts were then explanted (as they would be for heart transplants) and placed in preservation solution that was enriched with ribose for 4 hours. ATP levels were measured from tissue biopsies and revealed that 10 of the ribose-treated hearts had ATP levels higher than 12.3 micromoles per gram whereas saline-treated hearts (controls) had lower ATP levels, with 20% showing levels below 10 micromoles per gram of tissue. This provides support for the hypothesis that ribose may enhance the preservation of ATP levels in cardiac tissue, promoting normal heart function.4
Further animal studies have shown that ribose significantly enhances heart function after experimentally induced cardiac depression. Rats were injected with isoproterenol (a drug that stimulates sympathetic nervous system function) and had their abdominal aorta constricted to induce depression of heart function and reduce cardiac ATP levels. The decrease in ATP was primarily responsible for the depression of heart function. Continuous infusion of ribose for 24 hours replenished ATP concentrations to normal levels and normalized heart function in these animals.5
Ribose may strengthen and support the body’s crucial antioxidant defenses*
Ribose may support the body’s innate antioxidant mechanisms while promoting an antioxidant effect of its own. Intense exercise and other strenuous activity can induce the production of free radicals. Preliminary studies suggest that ribose can attenuate some of the effects of oxidation seen after performance of intensive exercise.
One small human study indicated that ribose administered at a dose of seven grams before and after a bout of cycling exercise may reduce free radical production.6 Seven volunteers ingested either ribose or placebo both before and after intense exercise. Markers of lipid peroxidation, including malondialdehyde, significantly decreased in the ribose-supplemented group, while increasing in the control group. The results of this study indicate a possible effect of ribose in supporting antioxidant activity.
Supports healthy energy levels in heart and muscle tissue*
After bouts of intense exercise, ATP levels have been shown to decrease by an average of 15 to 20%.7 The amount of ATP stored in the muscle is limited and so the body must have the potential to rebuild ATP stores. ATP is the fuel necessary for the integrity and function of a cell. In addition, several studies have found correlations between ATP content and heart function.1 Research that was also alluded to above suggests that ribose stimulates ATP synthesis and supports heart and muscle function by enhancing ATP levels in cardiac and muscle tissue. D-ribose is an essential building block for the synthesis of ATP through the pentose phosphate pathway.
The results of ribose supplementation enhancing ATP levels in muscle are evidenced by studies suggesting beneficial effects on anaerobic performance. In a randomized, placebo-controlled crossover study assessing the effects of acute ribose supplementation, participants receiving the ribose supplement had increases in mean power (a measure of average overall muscular strength output during the sprint) and peak power (a measure of the highest muscular strength output during the sprint) when undergoing a series of cycle sprints.8 While this effect was not noted in all of the six short cycling sprints that the participants underwent, the study does illustrate the potential benefits of ribose on ATP production and, secondarily, on enhancing exercise performance.
A second placebo-controlled trial investigated the effects of four weeks of ribose-supplementation (10 grams /day) on male bodybuilders. Of the 20 participants who were recruited, twelve completed the study. Each subject participated in a heavy-resistance training program designed to increase skeletal muscle mass. The effects of ribose on body composition (body weight, body fat, lean body mass, fat mass, and bone mineral content) were also assessed. The results suggested that ribose increased total work capacity and bench press strength compared to placebo, without altering body composition.9
Supports energy recovery after exercise*
Animal studies have suggested that the administration of ribose after exercise increases the rate of adenine salvage by five to seven-fold in muscle tissue7, supporting energy recovery after exercise. When ATP is utilized by muscle tissue, the degradation products include adenine nucleotides (Adenine is one of two purine bases that is a component of DNA). Adenine is recycled to synthesize DNA, and the salvage of adenine within the muscle tissue is crucial to energy recovery. Studies have shown that the presence of adequate ribose concentrations is the rate-limiting step in the purine salvage pathway. Therefore, increased adenine salvage could potentially help in the recovery and regeneration of ATP after intense bouts of activity.
A study investigated the effect of oral intake of ribose on the synthesis of AMP, a precursor to ATP.10 Participants performed intense cycle training for seven days. They then received either ribose (at a concentration of 200 mg/kg body weight, which is equivalent to 14 grams per day for an average 70 kilogram male) or placebo three times a day for the following three days. Exercise tests were performed again on day 4. Muscle biopsy samples were taken before the first training session, immediately after, and again five hours, 24 hours, and 72 hours after the last training session. No differences were seen in exercise performance between the groups. The intense exercise caused the ATP levels in muscle to decrease in both groups. However, at 72 hours post-exercise, the ribose group exhibited a much higher ATP level than the placebo group. The muscle levels of critical building blocks for ATP, including total adenine nucleotides (TAN) and inosine 5’-monophosphate (IMP), were also significantly higher in the ribose group compared to the placebo group at 24 hours after exercise. Ribose-supplementation was shown to enhance the resynthesis of ATP after intense exercise.

Carnitine CreatinateNeil E. Levin, CCN, DANLA 6/30/05LIKELY USERS: Athletes, Bodybuilders, Dieters, People who consume a lot of fat, People needing cardiovascular support (energy for the heart), People who need quick energy, especially for fast muscle response, People with muscle wasting problems (including the elderly), Weightlifters KEY INGREDIENTS: L-Carnitine and Creatine Monohydrate MAIN PRODUCT FEATURES: Carnitine Creatinate Monohydrate is a specialized form of Creatine bonded to L-Carnitine. Creatine is a compound natural to the human body that aids in the regeneration of ATP, the chemical energy used by muscle tissue. During exercise, large quantities of creatine are irreversibly consumed. Clinical studies have shown that oral supplementation with Creatine can increase the amount of Creatine available in muscles for ATP production. L-Carnitine is an amino acid that is necessary for the transfer of fatty acids into the fat-burning parts of the cell, facilitating energy production from fat. The combination of these two compounds can produce a synergistic effect, making NOW® Carnitine Creatinate an ideal energy supplement.

Date:
June 13, 2005 10:06 AM
Recognizing the Signs: Roadmap to a Healthy Heart by Louis McKinley Energy Times, January 2, 2004 From time immemorial, people have tuned into life's lessons that come from the heart. Sadly, times are changing: If you're like most inhabitants of today's harried world, you may be too distracted to detect important clues about your cardiovascular circumstances. And while heart lessons may be more complicated than simply connecting the physiological dots, understanding those heart messages are imperative for improving and maintaining your heart health. Every cell in your body relies on heart-powered blood flow to keep it supplied with nutrients, oxygen, hormones and other natural chemicals necessary for survival. Without that supply of life-giving substances, few cells in the body-including those within the heart itself-can survive very long. And just as damage to a major roadway can cause mayhem with traffic patterns, damage to blood vessels and the heart can wreak a lumpy cardiovascular havoc that blocks the passage of blood and endangers your heart's well-being. Your Heart Disease Chances Within the last ten years, scientific research performed by investigators around the world has focused on the specific factors that most strongly influence your chances of developing heart disease and suffering either a heart attack or a stroke. While much of your risk depends on your genetic inheritance and family history, several factors that determine your heart health are within your control. The most important factors you can do something about include: * Smoking: free radicals generated by burning tobacco causes significant damage to blood vessels and other cells * Lack of exercise: the human body is designed for consistent, moderate physical activity; without exercise, the body slacks off in creating antioxidant protection for arteries * Diabetes: when excess blood sugar persists, physiological processes begin that endanger the heart and arteries * Cholesterol: when oxidized (a chemical process that has been compared to a kind of internal rusting), cholesterol can form artery-blocking plaque; antioxidant nutrients like vitamin C and natural vitamin E may help the body limit this process * High blood pressure: excessive pressure within the blood vessels raises the risk of damage to the heart and arteries; a program of weight loss and exercise can help control blood pressure * Being overweight: the extra body fat carried around your middle is linked to a greater risk of heart problems Heart Attack Signs Do you think you know what a heart attack feels like? Well, if you think it feels like a dramatic pain somewhere in your chest that knocks you to the floor, you're probably wrong. "Most heart attacks do not look at all like what one of my colleagues calls the 'Hollywood' attack-the heart attack you see on television or in the movies," warns Julie Zerwic, MD, professor of surgical nursing who has studied what happens when people develop heart disease and suffer damage to their hearts. "The symptoms [of heart problems] are not necessarily dramatic. People don't fall down on the floor. They don't always experience a knife-like, very sharp pain. In fact, many people describe the sensation as heaviness and tightness in the chest rather than pain," she says. And, if you're a woman experiencing a heart attack, you may not even feel discomfort specifically in your chest. Instead you may experience a severe shortness of breath. The apparent ambiguity of the discomforts caused by a heart attack lead many people to either ignore them or take hours to realize they need to go to the emergency room at the hospital. Consequently, much fewer than half of all individuals undergoing a heart attack actually go to a hospital within an hour of the start of the attack. That delay can be a fatal mistake. "Timing is absolutely critical," laments Dr. Zerwic. "If treatment starts within a hour after the onset of symptoms, drugs that reestablish blood flow through the blocked coronary artery can reduce mortality by as much as 50%. That number drops to 23% if treatment begins three hours later. The goal is to introduce therapy within two hours." However, in Dr. Zerwic's research, only 35% of non-Hispanic whites go to the hospital within an hour of the start of a heart attack. And among African-Americans, the number of people going to the hospital right away drops to a frighteningly low 13%. Often, people will lie down or use a heating pad to relieve the tightness they feel in the chest," says Dr. Zerwic. "They may take some medicine and wait to see if that works. All these steps postpone needed treatment." Signs of a possible heart attack include: * Chest discomfort: Heart attacks most frequently cause discomfort in the center of the chest that can either go away after a couple of minutes (and come back) or persist. The discomfort may feel like strong pressure, fullness or pain. * Upper body discomfort: An attack may set off pain or discomfort in either or both arms, and/or the back, neck, jaw or stomach. * Shortness of breath: Chest discomfort is frequently accompanied by shortness of breath. But it's important to note that shortness of breath can take place even in the absence of chest discomfort. * Other signs: You can also break out in a cold sweat, or feel nauseated or light-headed. A Woman's Sleep Signs If you are a woman who suddenly experiences a marked increase in insomnia and puzzling, intense fatigue, you may be in danger of an imminent heart attack. In an attempt to understand how women's symptoms of heart problems differ from those of men, researchers talked to more than 500 women in Arkansas, North Carolina and Ohio who had suffered heart attacks. (Technically, what they had experienced is referred to as acute myocardial infarction.) They found that chest pain prior to a heart attack was only reported by about 30% of the women surveyed. More common were unusual fatigue, sleep disturbances and shortness of breath (Circulation Rapid Access, 11/3/01). "Since women reported experiencing early warning signs more than a month prior to the heart attack, this [fatigue and sleep problems] could allow time to treat these symptoms and to possibly delay or prevent the heart attack," says researcher Jean C. McSweeney, PhD, RN, nursing professor at the University of Arkansas for Medical Sciences in Little Rock. In Dr. McSweeney's study, more than nine out of ten women who had heart attacks reported that they had had new, disturbing physical problems more than a month before they had infarctions. Almost three in four suffered from unusual fatigue, about half had sleep disturbances, while two in five found themselves short of breath. Other common signs included indigestion and anxiety. "Women need to be educated that the appearance of new symptoms may be associated with heart disease and that they need to seek medical care to determine the cause of the symptoms, especially if they have known cardiovascular risks such as smoking, high blood pressure, high cholesterol, diabetes, overweight or a family history of heart diseases," says Dr. McSweeney. Dr. McSweeney warns that, until now, little has been known about signs that women are having heart trouble or heart attacks. The fact that most of Western medicine's past attention has been on heart problems in men has obscured the warning signs in women. As part of Dr. McSweeney's studies, she and her fellow researchers have discovered that more than 40% of all women who suffer a heart attack never feel any chest discomfort before or during the attack. "Lack of significant chest pain may be a major reason why women have more unrecognized heart attacks than men or are mistakenly diagnosed and discharged from emergency departments," she notes. "Many clinicians still consider chest pain as the primary symptom of a heart attack." Vitamins for Diabetes and Heart Disease Having diabetes significantly raises your chance of heart disease, which means that keeping your blood sugar levels under control can reduce your chances of suffering a heart attack. Today, 17 million Americans have diabetes and, as the country's population in general gains weight and fails to exercise, the number of people suffering this problem continues to grow. The first line of defense against diabetes consists of exercise and weight control. All you have to do is take a brisk walk for 30 minutes a day to drop your chances of diabetes (American Journal of Epidemiology 10/1/03). "We have found that men and women who incorporate activity into their lifestyles are less likely to develop type 2 diabetes than those who are sedentary. This finding holds no matter what their initial weight," said Andrea Kriska, PhD, professor of epidemiology at University of Pittsburgh Graduate School of Public Health. To help your body fight the development of diabetes, researchers also recommend vitamin C and natural vitamin E. Researchers working with lab animals at the University of California at Irvine have found that these antioxidant vitamins can help insulin (the hormone-like substance secreted by the pancreas) reduce harmful blood sugar. In addition, these vitamins shrink the chances of organ damage that can be caused by diabetes (Kidney International 1/03). In this investigation, these vitamins also helped reduce blood pressure, another risk factor that raises heart disease risk. "Blood pressure was lowered to normal, and free radicals were not in sufficient numbers to degrade the sugars, proteins and nitric oxide," notes Nick Vaziri, MD, professor of medicine at the University of California. "We think this shows that a diet rich in antioxidants may help diabetics prevent the devastating cardiovascular, kidney, neurological and other damage that are common complications of diabetes." Free Radical Blues Dr. Vaziri and his group of researchers found that untreated diabetes raised blood pressure and increased the production of free radicals, caustic molecules that can damage arteries and the heart. Free radicals can change blood sugar and other proteins into harmful substances, boosting tissue and heart destruction. In Dr. Vaziri's work with lab animals, he found that treating diabetes with insulin lowered blood pressure and helped keep sugar and protein from changing into dangerous chemicals, but allowed the free radicals to subvert nitric oxide, a chemical the body uses to protect itself from free radicals. In this investigation, adding vitamins C and E to insulin insulated the body's sugars, proteins and nitric oxide from oxidative assault. This produces a double advantage: Lowering the risk of heart disease and other damage to the body from diabetes. Maitake, an Oriental mushroom that has been shown to have many health benefits, can also be useful for people with diabetes who are trying to avoid cardiovascular complications. Laboratory studies in Japan demonstrate that maitake may help lower blood pressure while reducing cholesterol (Biological & Pharmaceutical Bulletin 1997; 20(7):781-5). In producing these effects, the mushroom may also help the body reduce blood sugar levels and decrease the risk of tissue damage. No Smoking! Tobacco smoke is one of the most notorious causes of heart problems. In the same way a hard frost exerts a death grip on a highway, the smoke from cigarettes can freeze up arteries and hamper their proper function. A healthy artery must stay flexible to comfortably allow adequate circulation. But "...when blood vessels are exposed to cigarette smoke it causes the vessels to behave like a rigid pipe rather than a flexible tube, thus the vessels can't dilate in response to increased blood flow," says David J. Bouchier-Hayes, MD, professor of surgery at the Royal College of Surgeons in Ireland, who has studied the deleterious effects of tobacco. This rigidity is called endothelial dysfunction. When arteries are rigid, blockages gum up vessels, clots and other impediments to blood flow appear, and your risk of heart attack and stroke increases (Circulation 2001 Nov 27; 104(22):2673). This condition can also cause chest pain (angina) similar to that caused by a heart attack, and should be evaluated by a knowledgeable health practitioner. Although all experts recommend you stop smoking to lower your heart disease risk, some studies have found that Pycnogenol(r), a pine bark extract that helps the body fight inflammation, may ease some of smoking's ill effects. In a study of platelets, special cells in the blood that can form dangerous blood clots, researchers found that Pycnogenol(r) discouraged platelets from sticking together (American Society for Biochemical and Molecular Biology 5/19/98). By keeping platelets flowing freely, this supplement may alleviate some of the heart-threatening clots that tobacco smoke can cause. In Ayurvedic medicine, a traditional therapy from India, an herb called guggul has also been used to lower the risk of blockages in arteries. This herb, derived from the resin of the mukul tree, has been shown to reduce cholesterol by about 25%. People taking this herb have also reduced their triglycerides (harmful blood fats) by the same amount (Journal Postgraduate Medicine 1991 37(3):132). The Female Version of Heart Disease
For one thing, women often don't suffer from the crushing chest pain that for most people characterizes a heart attack; instead, many women experience back pain, sweating, extreme fatigue, lightheadedness, anxiety or indigestion, signs that can be easily misread as digestive troubles, menopausal symptoms or indicators of aging. The genders also differ in how heart disease poses a threat. While men seem most endangered by the buildup of blockages in arteries, women apparently are more at risk from endothelial dysfunction. But more study needs to be done since, in many cases, researchers have been unable to pin down the precise mechanism that causes many women to die of heart disease. Scientists have found that the number of women in their 30s and 40s who are dying from sudden cardiac arrest is growing much faster than the number of men of the same age who die of this cause. But research by the Oregon Health & Sciences University and Jesse E. Edwards Cardiovascular Registry in St. Paul, Minnesota, shows that while doctors can pinpoint the coronary blockages that kill men, they can't find specific blockages in half of the female fatalities they have studied (American Heart Journal 10/03). "This was an unexpected finding. However, the study underscores the need to focus on what is causing these younger women to die unexpectedly because the number of deaths continues to increase," says Sumeet Chugh, MD, a medical professor at Oregon. Since the failure of arteries to relax probably contributes to heart disease in many women, eating red berries, or consuming supplements from berries such as chokeberry, bilberry or elderberry, may be important in lowering women's heart disease risk. These fruits help arteries expand and allow blood to flow freely. Red berries are rich sources of flavonoids, polyphenols and anthocynanins. The anthocyanins are strong antioxidants that give the berries their color. Research at the Indiana University School of Medicine have found that these chemicals can interact with nitrous oxide, a chemical produced by the body, to relax blood vessels (Experimental Biology conference 5/20/02). Working Out As researchers work to devise lifestyle roadmaps that can steer you around the perils of heart disease, they are finding that exercise is a key path to avoiding cardiovascular complications. A 17-year study of about 10,000 Americans found that those who exercised and kept their weight down (or took weight off and kept it off) experienced a significantly lower risk of heart problems (Preventive Medicine 11/03). "The fact is that those who both exercised more and ate more nevertheless had low cardiovascular mortality," says Jing Fang, MD, of the Albert Einstein College of Medicine in the Bronx, New York. Burning calories in physical activity may be the secret to reducing heart disease risk and living longer, she says. Dr. Fang's research used information collected from the First National Health and Nutrition Examination Survey in 1975 and then computed how much people exercised, how their body mass inDices varied and which of these folks died of heart disease during the next two decades. In the study, more than 1,500 people died of heart disease. Those who worked out and consumed more calories cut their risk of heart disease death in half. Exercise Is Essential "Subjects with the lowest caloric intake, least physical activity, and who were overweight or obese had significantly higher cardiovascular mortality rates than those with high caloric intake, most physical activity, and normal weight," Dr. Fang notes. The individuals in the study who were overweight and didn't exercise had a bigger risk of heart disease even if they tried (and succeeded) at eating less. "This suggests that heart disease outcome was not determined by a single factor, but rather by a compound of behavioral, socioeconomic, genetic and clinical characteristics," according to Dr. Fang. According to researchers, if your job requires a great deal of physical activity, your health will be better if you get another job. Exercise on the job not only doesn't decrease your risk of heart disease, it may actually raise it. The reason: On-the-job activity is linked to heart-endangering increases in job stress. Research into this subject, performed at the Keck School of Medicine of the University of Southern California, found that while recreational exercise slowed hardening of the arteries, workers who had to exert themselves during the workday had arteries that were blocked at a younger age (American Journal of Medicine 7/03). In this study, researchers examined about 500 middle-aged employees as part of what is called the Los Angeles Atherosclerosis Study. "We found that atherosclerosis progressed significantly faster in people with greater stress, and people who were under more stress also were the ones who exercised more in their jobs," says James Dwyer, PhD, professor of preventive medicine at the Keck School. According to Dr. Dwyer, "This suggests that the apparent harmful effect of physical activity at work on atherosclerosis-and heart disease risk-may be due to the tendency of high-activity jobs to be more stressful in modern workplaces. "It appears from our findings that the psychological stresses associated with physically active jobs overcomes any biological benefit of the activity itself." Playful Workouts On the other hand, the scientists found that heart disease drops dramatically among those who exercise the most in their spare time. In the study, people who vigorously worked out at least three times a week had the lowest risk. But even those who just took walks enjoyed better heart health than people whose most strenuous activity was working the TV remote. Dr. Dwyer says, "These results are important because they demonstrate the very substantial and almost immediate-within one or two years-cardiovascular benefit of greater physical activity."
