Bodybuilding supplements are substances taken by athletes involved in weight training or other sports to aid in the building of lean muscle mass or to cause fat loss. Bodybuilding supplements may also be used to improve sports performance and improve recovery from events and training. One important distinction exists in many weight training groups between supplements and anabolic steroids. There is a common misconception among non-supplement-users that supplementation for muscle-building purposes is the same as steroid use or, at the very least, leads to steroid use.[citation needed] However, this charge is often challenged by supplement users on the grounds that supplements

A gainer is a bodybuilding supplement usually comprised of both high and low glycemic carbohydrates and protein (usually in the form of calcium caseinate, milk and whey protein) and often other nutrients such as certain vitamins and minerals. Gainers are used by bodybuilding and strength athletes, both amateur and professional alike. When performing intensive exercise the stress can cause the release of hormones such as cortisol in order to quickly make available energy to the body. Cortisol forces breakdown of glycogen, protein (muscle) and fat deposits which are used in gluconeogenesis. Gainers seek to combat this effect after (and sometimes during)

Metabolife was founded in the early 1990's by Michael Ellis, a former police officer on probation for charges relating to his involvement with a methamphetamine lab.[3][4] Ellis and a boyhood friend, Michael Blevins, were arrested in 1989 for producing and distributing methamphetamine. Both Ellis and Blevins cooperated with federal authorities in return for lighter sentences. Following Blevins' release from prison, the two formed Metabolife to market ephedra, an herbal supplement containing compounds chemically related to methamphetamine.[4] Metabolife's ephedra supplement was initially marketed as a bodybuilding supplement, but in 1995 was rebranded as an aid for dieting. The product became highly successful

Glutamine is the most abundant amino acid found in human muscle and is supplemented because supplement manufacturers claim the body's natural glutamine levels are depleted during anaerobic exercise. It is argued that bodybuilders should supplement with glutamine, as deficiency may lead to a weakened immune system and wasting of muscle tissue.[citation needed] It is sold as a micronized, instantly soluble powder. Some studies [2] [3] have shown there to be no significant effect of glutamine on bench press strength, knee-extension torque or lean muscle mass when compared to controls taking a placebo, though another study found that glutamine is beneficial

A thermogenic is a broad term for any supplement that the manufacturer claims will cause thermogenesis, resulting in an increased metabolic rate, increased body temperature and consequently an increased rate in the burning of body fat. Until recently almost every product found in this supplement category comprised the "ECA stack": ephedrine, caffeine and aspirin. However, on February 6, 2004 the Food and Drug Administration (FDA) banned the sale of ephedra and its alkaloid, ephedrine, for use in weight loss formulas. Several manufacturers replaced the ephedra component of the "ECA" stack with bitter orange or citrus aurantium (containing synephrine) instead of

Amino acids are the building blocks of protein; the body breaks consumed protein into amino acids in the stomach and intestines. There are three branched chain amino acids (BCAAs): leucine, isoleucine, and valine. Each has numerous benefits on various biological processes in the body. Unlike other amino acids, BCAAs are metabolised in the muscle and have an anabolic/anti-catabolic effect on it. [5]

There are several naturally occurring plants and vitamins as well as synthetic chemicals that supplement companies claim may produce an increase in testosterone levels. However, the validity of many of these products is questionable due to a lack of valid scientific research showing their effectiveness at this time. Some commonly taken supplements of this type are ZMA and Tribulus terrestris. The relatively new drug 4-androstene-3,6,17-trione may increase the testosterone-estrogen ratio.[citation needed] Excess testosterone can cause undesirable side effects, such as hair loss and acne,[citation needed] and may be converted into estrogens,[11] which can have undesirable effects on males.[12]

In addition to being consumed in milk, casein is used in the manufacture of adhesives, binders, protective coatings, plastics (such as for knife handles and knitting needles), fabrics, food additives and many other products. It is commonly used by bodybuilders as a slow-digesting source of amino acids as opposed to the fast-digesting whey protein, and also as an extremely high source of glutamine (post-workout). Another reason it is used in bodybuilding is because of its anti-catabolic effect, meaning that casein consumption inhibits protein breakdown in the body. Casein is frequently found in otherwise nondairy cheese substitutes to improve consistency, especially

Meal Replacement Products (MRPs) are either pre-packaged powdered drink mixes or edible bars. Both are consumed in the place of a whole-food meal. Generally MRPs are high in protein, low in fat, have a low to moderate amount of carbohydrates, and contain a wide array of vitamins and minerals. The majority of MRPs use whey protein, calcium caseinate or micellar casein, soy protein, and egg albumin as the protein source. Carbohydrates are typically derived from maltodextrin, oat fiber, brown rice, or wheat flour. Some also contain flax oil powder as a source of essential fatty acids. MRPs can also contain other ingredients

The activity of boldenone is mainly anabolic, with a low androgenic potency. It has a very long half-life, and can show up on a steroid test for up to 1.5 years, due to the long undecylenate ester attached to the parent steroid. Boldenone will increase nitrogen retention, protein synthesis, increases appetite and stimulates the release of erythropoietin in the kidneys. The drug is commonly used in doping within bodybuilding, even though this use is illegal. If intended to assist in bodybuilding, the drug is taken as part of a steroid stack of other anabolic steroids, usually with a potent androgen like

-HTP, which is found in minute amounts in certain foods like cheese and the white meat of poultry,[citation needed] is often sold as an over-the-counter therapeutic supplement. In this case, it is usually sourced from the seeds of Griffonia simplicifolia. 5-HTP in supplement form is typically sold in 50 mg or 100 mg gelatin or vegetarian capsules.

A dietary supplement, also known as food supplement or nutritional supplement, is a preparation intended to supply nutrients, such as vitamins, minerals, fatty acids or amino acids, that are missing or are not consumed in sufficient quantity in a person's diet. Some countries define dietary supplements as foods, while in others they are defined as drugs. Supplements containing vitamins or dietary minerals are recognised by the Codex Alimentarius Commission, the United Nations' highest authority on food standards, as a category of food.[1]

A clinical trial found that patients taking an L-arginine supplement following a heart attack didn't improve in their vascular tone or their hearts' ability to pump. In fact, more patients died who were taking L-arginine than placebo and the study was stopped early with the recommendation the supplement not be used by heart attack patients. The supplement still is widely marketed.[6][7][8]

Calorad is a liquid protein weight loss supplement which was first introduced to the US and Canadian marketplace in 1984. It has been advertised on both television and radio. Calorad is manufactured by NutriDiem and is marketed by several companies including Essentially Yours Industries and Nysante, all of which are headquartered in Canada.
