BCAA Post Workout Powder is a blend of 5000mg of branched-chain amino acids and Glutamine for lean muscle and recovery. It contains the ideal ratio of 2 parts Leucine to 1 part Isoleucine and Valine. These amino acids increase protein synthesis and nitrogen retention, both essential to building lean muscle. BCAAs are metabolized directly in the muscle and are considered essential because the body cannot produce them from other compounds. Instead, they must come from diet or supplementation.
