R1 BCAAs

When it comes to muscle maintenance, BCAAs are literally essential. This group of aminos cannot be synthesized within our body; they must be obtained from high protein foods and supplements. R1 BCAAs delivers all three critical amino acids in a 2:1:1 ratio of leucine to isoleucine and valine. Our BCAA formula is micronized to easily mix into water or your beverage of choice.*
