Met-Rx has unleashed BCAA 2200 - a potent blend of all three Branched Chain Amino Acids the bodybuilders and athletes demand to powder their workouts. BCAA 2200 employs state of the art NitroGel technolgoy to maximize delivery of BCAA's per softgel. BCAAs are especially important for bodybuilders since they comprise a large percentage of the amino acid composition of muscle. BCAAs are also the only aminos that are directly metabolized in the muscle as opposed to the liver. BCAAs also provide muscle nitrogen support for a variety of metabolic funtions, which can be especially important during heavy training.
