The glimmer-of-hope reasons include: to improve physical appearance or physique, increase muscle mass, optimize general health, and help meet physical demands on their bodies. Unfortunately, most supplements don\u2019t work.

Case in point, the popular <\/span><span style=\"font-weight: 400;\">branch-chain amino acids (BCAAs),<\/span> <span style=\"font-weight: 400;\">specifically the BCAA leucine, which is known to activate the muscle-building process. Unfortunately, <\/span><span style=\"font-weight: 400;\">simply activating the process is not enough to promote muscle growth.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">BCAA research<\/span><span style=\"font-weight: 400;\"> indicates they do not provide any benefits above and beyond the amino acids athletes normally consume when eating protein-rich food at meals and snacks. To see any meaningful muscle-building effect, you actually need to have many other amino acids present (as happens when you eat real food, as opposed to an isolated amino acid), as well as enough calories\u2014and of course, a good strength training program plus adequate sleep.\u00a0<\/span><\/p>\n<h4><b>Varied responses<\/b><\/h4>\n<p><span style=\"font-weight: 400;\">Even among supplements that \u201cwork,\u201d the response varies greatly from person to person. Case in point, beta-alanine, a supplement used by athletes such as sprinters, rowers, and wrestlers to reduce muscular fatigue and improve endurance during high-intensity exercise that lasts for 1 to 4 minutes. The varied responses can be related to not only genetics and biological factors, but also to the power of the mind, the placebo effect, adequate fuel, and enough sleep. Hence, when a supplement does \u201cwork\u201d for some athletes, the response may be due not to the supplement\u2014but rather to the athletes getting serious about taking better care of their bodies, eating wisely and getting enough sleep (4).\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Enhancing sports performance may not need rocket science, after all?<\/span><\/p>\n<hr \/>\n<p><em><span style=\"font-weight: 400;\">Sports Nutritionist Nancy Clark, MS, RD counsels both casual and competitive athletes in the Boston-area (Newton; 617-795-1875).
