Amino acids are the building blocks of all proteins - muscle, skin, hormones, enzymes, antibodies and many more.
The most important aspect of a supplement is its amino acid profile. Having high potency is not enough - the amino acids must be present in the right ratio.
Free form amino acids consist of single amino acids on their own. Peptide-bound means a few joined together in a short chain. This supplement contains both and includes all the essential and branched chain amino acids which cannot be made by the body. Contains no synthetic Tryptophan.
