BCAA"s (Branched Chain Amino Acids) consist of the three amino acids Leucine, Isoleucine and Valine. BCAA"s cannot be produced in the body and must be supplied through the diet. BCAA"s have been shown to help with protein synthesis, helping your body cope with the stress of exercise. BCAA"s are required to maintain lean tissue and studies have shown they preserve your stores of glycogen (a stored form of carbohydrate that can be converted to energy). BCAA"s also prevent catabolism during training and therefore can improve lean growth. BCAA"s are not like other amino acids as they are not metabolised in the stomach, and are instead metabolised directly in the muscle. This unique quality means that they build lean tissue and stop catabolism. BCAA Plus has been independently tested for WADA banned substances by HFL Sport Science under the INFORMED-SPORT program. Each batch of BCAA Plus undergoes rigorous testing to provide the highest level of assurance that they are safe for athletes to use. HFL is the world"s largest sports drug surveillance and research laboratory and the INFORMED-SPORT program is supported by a number of recognized sports bodies, including UK Sport. Please note actual image may vary.
