Depending on the flavor, Keto Chow uses either milk protein isolate or beef protein and beef bone broth. You can find the amino acid profiles for those on the Keto Chow nutrition page.

There are nine “essential” amino acids. Meaning, your body can’t synthesize them: phenylalanine, valine, threonine, tryptophan, methionine, leucine, isoleucine, lysine, and histidine. You can find all nine in both protein-types of Keto Chow.
