Despite some supplement labels claiming zero calories, branched-chain amino acids (BCAAs) do contain caloric energy, typically around 4 calories per gram. This can be a source of confusion for fitness enthusiasts, especially those strictly monitoring their intake or practicing intermittent fasting.

Despite some labels claiming zero calories, all amino acids—including branched-chain amino acids (BCAAs)—are a source of energy for the human body. A typical gram of amino acids contains approximately 4 calories, a fact often obscured by supplement manufacturers. This often leads to confusion for those tracking their caloric intake, particularly athletes and individuals on a calorie-restricted diet.
