BCAAs pour Muscle Preservation During Weight Loss

B

Systematic review of 36 studies found BCAA supplementation during caloric restriction preserved lean body mass better than restriction alone. Observational study (n=4,429) found inverse association between BCAA intake and obesity (OR 0.66). Benefits are most pronounced when total protein intake is inadequate.
