Abstract

Bodybuilding supplements are dietary supplements commonly employed by those involved in bodybuilding, weightlifting, mixed martial arts, and athletics for the aim of facilitating a rise in lean body mass. The intent is to extend muscle, increase weight, improve athletic performance, and for a few sports, to simultaneously decrease percent body fat so on create better muscle definition. Among the foremost widely used are high protein drinks, pre-workout blends, branchedchain amino acids (BCAA), glutamine, arginine, essential fatty acids, creatine, HMB, whey protein, ZMA and weight loss products. Supplements are sold either as single ingredient preparations or within the sort of “stacks” – proprietary blends of varied supplements marketed as offering synergistic advantages [1]. While many bodybuilding supplements also are consumed by the overall public the frequency of use will differ when used specifically by bodybuilders. One metaanalysis concluded that – for athletes participating in resistance exercise training and consuming protein supplements for a mean of 13 weeks – total protein intake up to 1.6 g/kg of weight per day would end in a rise in strength and fat-free mass, but that higher intakes wouldn’t further contribute.
