Efficacy: The minimal research on DHEA's use to enhance exercise and athletic performance provides no evidence of benefit [129]. Efficacy: Numerous small studies have assessed quercetin in supplemental form as a potential ergogenic aid in young adult, mostly male, participants. The agency contended that there is no history of use or data offering sufficient assurance that this compound is not associated with "a significant or unreasonable risk of illness or injury" [204,205]. The FDA permits dietary supplements to contain only "dietary ingredients," such as vitamins, minerals, amino acids, herbs, and other botanicals. J Strength Cond Res 2007;21:348-53. Furthermore, arginine typically had no effect on nitric oxide concentration, blood flow, or exercise metabolites (e.g., lactate and ammonia), especially when well-trained athletesincluding cyclists, tennis players, and judo practitionerstook the supplement for 128 days [30]. In a position statement, AND, DoC, and ACSM do not recommend routine supplementation of iron except in response to a health care providers instruction, and note that such supplementation is only ergogenic if the individual has iron depletion [12].

Creatine supplementation enhances muscular performance during high-intensity resistance exercise. Elite and recreational athletes perform at their best and recover most quickly when they consume a nutritionally adequate diet with sufficient fluids and when they have appropriate physical conditioning and proper training. Some athletes use glutamine supplements in the hope that they will attenuate exercise-induced immune impairment and reduce their risk of developing upper respiratory tract infections. The supplement provided no benefits compared with placebo in increasing muscle strength, lean body mass, or testosterone concentrations [130]. Beta-alanine is produced in the liver, and relatively small amounts are present in animal-based foods such as meat, poultry, and fish. Pharmacogenetics 1993;3:302-11.

[, Oketch-Rabah HA, Roe AL, Gurley BJ, Griffiths JC, Giancaspro GI. The authors concluded that supplemental arginine (either alone or, more commonly, in combination with other ingredients, such as branched-chain amino acids [BCAAs] and lysine) provided little or no enhancement of athletic performance and did not improve recovery from exhaustion [33]. [. This regulatory change did not affect the rule on providing dietary supplements to student-athletes. Depending on the study (and therefore participants age, fitness level, and use of other supplements as well as the nature and duration of the exercise), extra arginine might either reduce HGH secretion [34] or raise HGH and IGF-1 secretion [35]. Effect of caffeine on sport-specific endurance performance: a systematic review. The use of drugs and nutritional supplements in top-level track and field athletes. Chicago, IL: Academy of Nutrition and Dietetics; 2012:36-57. L-arginine is an amino acid found in many protein-containing foods, especially animal products and nuts. The BCAAs might delay feelings of fatigue or help maintain mental focus by competing with the amino acid tryptophan (a precursor of the neurotransmitter serotonin that regulates mood and sleep) for entry into the brain, but this effect has not been well studied [72,74,75].

For a potential benefit to athletic performance, users should consume caffeine 15 to 60 minutes before exercise [13,85]. Supplement manufacturers are responsible for determining that their products are safe and their label claims are truthful and not misleading, although they are not required to provide this evidence to FDA before marketing their products. The reality is that the use of dietary supplements can be risky, and that awareness and caution must be exercised when considering their use.

Growth hormone, IGF-1 and insulin and their abuse in sport. High-protein diets (e.g., those providing two to three times the RDA of 0.8 g/kg/day for healthy adults and 0.85 g/kg/day for adolescents) do not appear to increase the risk of renal stones or dehydration; compromise renal function; reduce bone health; or, when consumed for several months, alter glomerular filtration rate or blood levels of lipids, glucose, creatine, or blood urea nitrogen [160-164].

The company was formed by Lebron James in partnership with Arnold Schwarzenegger, Cindy Crawford and Lindsey Vonn, and offers a variety of nutritional products for . Many study findings suggest that supplementation with sodium bicarbonate is most likely to improve the performance of trained athletes [181,182]. Caffeine supplementation is more likely to help with endurance-type activities (such as running) and activities of long duration with intermittent activity (such as soccer) than more anaerobic, short-term bouts of intense exercise (such as sprinting or lifting weights) [91]. Researchers have found that a creatine supplement that also contained caffeine, taurine, and amino acids helped athletes feel focused and increased the time that it took for them to feel exhausted. [. J Int Soc Sports Nutr 2015;12:39. [, Merry TL, Ristow M. Do antioxidant supplements interfere with skeletal muscle adaptation to exercise training? The American Academy of Pediatrics warns that caffeine-containing energy drinks in particular "have no place in the diets of children or adolescents" and are not suitable for use during routine physical activity [101].

Beta-alanine, a type of amino acid that the body does not incorporate into proteins, is the rate-limiting precursor to the synthesis of carnosinea dipeptide of histidine and beta-alaninein skeletal muscle. Human Performance Resource Center; Consortium for Health and Military Performance. Carnosine helps buffer changes in muscle pH from the anaerobic glycolysis that provides energy during high-intensity exercise but results in the buildup of hydrogen ions as lactic acid accumulates and dissociates to form lactate, leading to reduced force and to fatigue [51]. Nutrients 2014;6:5224-64. The National Collegiate Athletic Association and the World Anti-Doping Agency ban the use of DHEA [105,128]. Efficacy: Although studies have investigated HMB for two decades, they have used substantially different periods of supplementation (1 day to 6 weeks) and daily doses (1.5 to 6 g; most commonly 3 g based on evidence that this dose provides equivalent results to 6 g and better results than 1.5 g) [61,63,64].

Some governing organizations prohibit the use of hemp or CBD. [, Negro M, Giardina S, Marzani B, Marzatico F. Branched-chain amino acid supplementation does not enhance athletic performance but affects muscle recovery and the immune system. Dietary supplements that contain citrulline provide either citrulline or citrulline malate. Athletes following vegetarian and vegan diets may need to take particular care to ensure that they are obtaining enough of the above nutrients through their diet. About 80% of the body's citrulline is converted in the kidneys into arginine, another amino acid (see section on arginine) [30]. Vitamin C and E supplementation hampers cellular adaptation to endurance training in humans: a double-blind, randomised, controlled trial. Other, usually more expensive, forms of creatine (e.g., creatine ethyl ester, creatine alpha-ketoglutarate, and buffered forms of creatine) have not been proven to have superior ability to creatine monohydrate for enhancing muscle creatine levels, digestibility, product stability, or safety [73,112,123]. Also, use of antiinflammatories and pain medications can lead to some blood loss from the gastrointestinal tract, thereby decreasing iron stores. 11th ed. No ergogenic effets of ginseng (, Allen JD, McLung J, Nelson AG, Welsch M. Ginseng supplementation does not enhance healthy young adults' peak aerobic exercise performance. Most complete proteins (those that contain all EAAs) are composed of about 40% EAAs, so a meal or snack with 25 g total protein provides about 10 g EAAs. Another systematic review and meta-analysis compared the effects of iron supplementation with no supplementation on exercise performance in women of reproductive age [149]. Dietary supplements to enhance exercise and athletic performance come in a variety of forms, including tablets, capsules, liquids, powders, and bars.
