Creatine Supplementation Creatine supplementation is claimed to increase muscle power by playing a role in the transfer of energy to help the muscle contract. Supplement labels state that "creatine is converted to phosphocreatine, which is important for short energy bursts such as sprinting and weight lifting" and that "depletion of phosphocreatine can result in muscle fatigue and fading muscle power." Claims are also made that supplementation increases muscle body mass. Creatine is not subjected to FDA testing, and the purity and hygienic condition of commercial creatine products may be questionable [21]. www.quackwatch.org /01QuackeryRelatedTopics/DSH/creatine.html   (1832 words)

Creatine kinase - Wikipedia, the free encyclopedia Creatine kinase (CK), also known as phosphocreatine kinase or creatine phosphokinase (CPK) is an enzyme (EC 2.7.3.2) expressed by various tissue types. Its function is the catalysis of the conversion of creatine to phosphocreatine, consuming adenosine triphosphate (ATP) and generating adenosine diphosphate (ADP) and the reverse reaction. In tissues that consume ATP rapidly, especially skeletal muscle, but also brain and smooth muscle, creatine phosphate serves as an energy reservoir for the rapid regeneration of ATP, the major source of energy in biochemical reactions. en.wikipedia.org /wiki/Creatine_kinase   (406 words)

Creatine Monohydrate : Creatine Supplement Facts, Side Effects and Benefits Creatine is a natural substance found in our muscle cells, especially around the skeletal muscle with about 95% of the body's creatine supply, and the remaining 5% is stored in other parts of the body. Creatine is a metabolite produced in the body which mainly consists of three amino acids namely - methionine, arginine, and glycine. Creatine monohydrate, is a dietary supplement that athletes and many bodybuilders use to increase high intensity exercise performance, increased strength, have fuller looking muscles, increase body mass and faster post workout muscle recovery. www.creatine-monohydrate.org   (497 words)

Creatine Studies have shown that ingesting creatine mono hydrate raises the level of creatine phosphate in muscles thereby increasing strength and the ability to sustain intense exercise. Creatine is an amino acid used in muscles to supply energy to the muscle cell. Creatine is no stranger to athletes because it appears to provide an edge in competition. www.unm.edu /~shc1/creatine.html   (506 words)

Absolute Creatine Creatine is a compound that can be made in our bodies or taken as a dietary supplement. Creatine is made up of three amino acids - Arginine, Glycine and Methionine.

Creatine Creatine supplementation has been likened to carbo-hydrate-loading, except that the latter boosts performance in endurance (aerobic) events such as marathons, while creatine is used for high-intensity (anaerobic) activities lasting less than one minute, such as sprinting, jumping, and weight lifting. Creatine is an amino acid, but unlike most amino acids it is not incorporated into protein. Taking creatine supplements may depress the body's own synthesis of the substance, which may not return to normal once you stop taking the supplements. www.berkeleywellness.com /html/ds/dsCreatine.php   (576 words)

Brawny Brains: Creatine pills may aid memory and cognition: Science News Online, Aug. 16, 2003   (Site not responding. Last check: 2007-10-26) Creatine's popularity among athletes and body builders fuels a market of more than $200 million per year for the pills in the United States. To see whether extra creatine could help meet the brain's demands during quick thinking, Caroline Rae of the University of Sydney and her colleagues gave a daily pill to each of 45 university students who were vegetarians. Creatine can cause bad breath, flatulence, and weight gain from excess water retention—cues that might have encouraged volunteers to unconsciously push harder on the tests, he suggests. www.sciencenews.org /20030816/fob4.asp   (616 words)

Sportscience Creatine Review Creatine supplementation for a month or two during training has been reported to promote further gains in sprint performance (5-8%), as well as gains in strength (5-15%) and lean body mass (1-3%). Creatine in the form of phosphocreatine (creatine phosphate) is an important store of energy in muscle cells. Furthermore, creatine and phosphocreatine have been used medically to reduce muscle wasting after surgery and to improve heart function and exercise capacity in people with ischemic heart disease (Pauletto and Strumia, 1996; Gordon et al., 1995). www.sportsci.org /traintech/creatine/rbk.html   (4283 words)

Alternative Medicine - Herbs, Yoga and Nutritional Supplements - Health And Age In addition, there is concern about athletes taking pure creatine supplements because of the potential for serious side effects such as damage to the kidneys in otherwise healthy people and the risk of inhibiting the body's natural formation of creatine. Given that some studies suggest that creatine supplements may improve exercise performance in athletes, researchers have asked the question of whether this benefit may be conferred to people with neuromuscular disorders as well. Creatine may increase the likelihood of damage to the kidneys if taken with cimetidine (a medication for used for heartburn and to prevent ulcers), diuretics, probenecid (used for gout), or non-steroidal anti-inflammatory (NSAID) medications (such as ibuprofen). www.healthandage.com /html/res/com/ConsSupplements/Creatinecs.html   (2281 words)

BBC NEWS | Health | Creatine 'boosts brain power' Creatine is a natural compound found in muscle tissue, and has been popular with athletes looking for ways to increase fitness. Vegetarians were used for the tests, mainly because meat in the diet is in itself a source of creatine, and it would be difficult to gauge exactly how much an individual had consumed. Dr Rae believes that the creatine increases the amount of energy available to the brain for computational tasks, improving general mental ability. news.bbc.co.uk /2/hi/health/3145223.stm   (421 words)

Bodybuilding.com - Creatine Monohydrate Information and Product Listing! Creatine Monohydrate FAQ! A: Creatine is not totally stable in solution, so it's definitely not a good idea to keep it mixed with liquid for days, but there shouldn't be a problem mixing it six to eight hours before it's consumed. Creatine, which is present naturally in the body, works by increasing the muscle's ability to refuel quickly. Creatine can help athletes get in some extra lifts in training, or some extra force in a game, but the effect is not so powerful that athletes "can exceed breaking points for muscle tendons and fibers," he said. www.bodybuilding.com /store/creatine.html   (1990 words)

Creatine Supplement - Buy Online - Creatine Monohydrate Supplement Here Has powdered creatine upset your stomach, given you diarrhea, etc? The most likely reson for this is that stomach acid destroys creatine, it has been estimated that as much as 66% of the creatine you take is never absorbed. Next people mixed their creatine with grape juice to try to get better results, but since juice is also acidic it destroys some of the creatine. The problem is that all creatine powders and even liquids must pass through stomach acid and lose most of their potency and lead to unwanted side affects, stomach aches, etc. Plus some of them have as much as 75 grams of sugar per dose, that much sugar can lead to health problems and getting fat. www.trulyhuge.com /creatine.htm   (1407 words)

Creatine Monohydrate: by Ray Sahelian, M.D., Honest Creatine Research Update, Benefits and Side Effects Creatine seems to work well for most people no matter when they take it, but it would seem logical that taking it right before, during, or after a workout may be a better option than taking it at a sedentary time. Creatine should not influence blood sugar to any significant extent, but since very high doses may harm the kidneys over the long run, someone who is diabetic should not take more than 1 gram of creatine a day. Diagnosis is established by measurement of guanidinoacetate and creatine in biologic fluids and in vivo proton magnetic resonance spectroscopy by the total lack of intra-cerebral creatine/phosphocreatine demonstrating. www.raysahelian.com /creatine.html   (7300 words)

Creatine | Creatine Information | Creatine Monohydrate | Creatine Loading | Creatine Serum | Creatine Ester | Creatine ... Creatine is often taken by humans as a supplement for those wishing to gain muscle mass (bodybuilding). After all creatine’s undeniable presence in professional (and amateur) sports sends a strong message to the masses especially young aspiring athletes who (by the mere pressure to excel at their respective sports) are often impelled to emulate the professional ranks. Because researchers concluded that creatine was efficiently absorbed even when combined with caffeine it does not appear from the results of this study that caffeine exerts a negative effect on the uptake of creatine into muscle tissue. www.creatineworld.com   (3544 words)
