BCAA’s or branched chain amino acids are a group of 3 essential amino acids: leucine, iso-leucine, and valine. They are considered essential amino acids because they can’t be produced by the body. Instead they must be obtained from food. Our BCAA capsules come in a convenient capsule format and deliver the 3 essential amino acids leucine, isoleucine & valine in a 2:1:1 ratio.
