Optimum Nutrition BCAA
Anabolic & Anti-Catabolic Muscle Support
Used before endurance training, the Branched Chain Amino Acids (BCAAs) leucine, isoleucine and valine can help spare muscle. Used after strength training, they help kick-start protein synthesis which plays an important role in muscle building. ON’s BCAA 1000 Caps deliver 1000 mg of BCAAs per serving in the preferred 2:1:1 ratio of leucine to isoleucine and valine.
