Curious about BCAAs? Our expert explains what they’re good for — and how to right-size your intake.
Your body requires three branched-chain amino acids, or BCAAs: leucine, isoleucine, and valine. Leucine typically gets most of the attention because of its ability to stimulate muscle growth, but each offers key benefits. Isoleucine helps regulate blood sugar and create hemoglobin (proteins that carry oxygen within your body), while valine acts as a mild stimulant.
