When it comes to muscle maintenance, BCAAs are literally essential. This group of amino acids cannot be synthesized within our body; they must be obtained from high-protein foods and supplements. R1 BCAA delivers the three critical amino acids in a 2: 1: 1 ratio of leucine to isoleucine and valine. Our BCAA formula is also flavorless and micronized for easy mixing with your shake or beverage of choice. * * How to use: Mix one (1) scoop with 8-10 oz. of cold water and consume before, during or after training.
