Our amino acid capsules offer a full range of natural amino acids as well as micronized amino acid blends derived from isolated, concentrated and hydrolyzed protein sources. Increase your intake of essential amino acids that may be lacking in your diet. This dietary supplement is a blend of essential and non-essential amino acids that support cell function and the production of enzymes and neurotransmitters. Simply put, amino acids are the building blocks of life. When you eat protein, your body breaks it down into its individual amino acids, rearranges them, refolds them and converts them into whatever it needs at the time. The group of amino acids of greatest concern to athletes are leucine, isoleucine, and valine, known as branched-chain amino acids (BCAA). As the name suggests, these amino acids have a special shape that allows them to be used in ways that other amino acids can only dream of.
