BCAAs show up on plenty of drink and supplement labels. Here's what the letters stand for and what they are.
BCAA stands for branched-chain amino acids
Amino acids are the building blocks of protein. Three of them, leucine, isoleucine and valine, have a branched shape in their chemical structure, which gives the group its name.
They're "essential" amino acids
Your body uses 20 amino acids. Nine are called essential because your body can't make them, so they have to come from what you eat and drink. All three BCAAs are on that list.
Where do BCAAs come from in food?
Most people get BCAAs from protein-rich foods such as meat, fish, eggs, dairy, soy, beans and lentils. A drink with added BCAAs is simply another source.
Why are they popular with active people?
BCAAs are a common ingredient in sports nutrition, and researchers continue to study their role around exercise. The evidence is still developing, and results vary between studies, so we don't make promises about what they'll do for you. We include them because they're a familiar part of an active routine, alongside the electrolytes and vitamins in every can.
