Abstract
Because there is widespread belief among athletes that special nutritional practices will enhance their achievements in competition, the use of supplements has become common. Accompanying the growth in supplementation by athletes has been a corresponding increase in exaggerated claims or misleading information. This article reviews several supplements currently popular among bodybuilders and other strength athletes in order to clarify which products can be expected to produce results. Included in the discussion are creatine monohydrate, beta-hydroxy beta-methylbutyrate, whey protein, phosphatidylserine, and selected amino acids and minerals. (Alt Med Rev 1997; 2(3):184-201)
