BCAAs

Branched-chain amino acids (leucine, isoleucine, and valine) are essential amino acids that play a key role in muscle protein synthesis and energy metabolism. They are commonly supplemented by athletes and fitness enthusiasts to support muscle growth, reduce fatigue, and aid recovery during intense training.

Research Summary

Clinical studies demonstrate that BCAAs support muscle protein synthesis and reduce muscle soreness, particularly following resistance training. However, evidence suggests they are most beneficial when total protein intake is adequate; consuming whole protein sources may be equally effective. Research on endurance and fatigue reduction shows modest benefits, with greater effects observed in individuals with insufficient dietary protein.
