BCAA’s: To Supplement Or Not To Supplement


Assuming that you have adequate protein intake from consuming animal proteins where all the essential amino acids are available there will be 0 benefit from supplementing with Branched Chain Amino Acids (Leucine, Valine, Isoleucine), and that supplementing with BCCA’s may even have a deleterious effect on protein synthesis. In theory when you take in an isolated form BCAA supplement (and other isolated forms of amino acids) you can promote a competition for assimilation with the other essential (and non-essential) amino acids that could possibly be ‘kicked-out’ of the amino pool negatively effecting a post exercise protein synthesis response.
