Beta-alanine is a precursor of the dipeptide carnosine. This tiny little protein prevents the acid level in working muscles from rising too fast. Carnosine works as a buffer, which enables muscles to keep working longer before they become fatigued. The effect of beta-alanine is similar to that of creatine, but it works in a different way. That’s why sports scientists suspect that a combination of creatine and beta-alanine could be a pretty effective mix.
