Branched-chain amino acids (BCAAs) are a popular sports supplement with bodybuilders and athletes. But you don’t need to look for them in a bottle as our diet naturally contains them as part of the amino acid building blocks of protein. With claims of increased muscle protein synthesis, decreased muscle protein breakdown, enhanced endurance and less muscle soreness, they seem to be an essential supplement that no athlete can do without. In this episode, I’ll look at those claims and explore the evidence. TL;DR – save your money on BCAA supplements and just eat a variety of high-protein foods which is what athletes pretty much do already.
