.Numerous studies show HMB improves muscle recovery after strenuous exercise. Researchers think HMB reduces inflammation and oxidative stress in muscle cells after exercise-induced muscle damage occurs. Increased cholesterol synthesis within muscle cells may also aid in recovery.
HMB plays a key nutritional role as it is considered the most important regulator of muscle protein anabolism, due to its ability to stimulate the mechanistic Target of Rapamycin (mTOR) signaling pathway, which increases protein synthesis, and attenuates the proteasome pathway, inducing muscle protein catabolism
