Beta-hydroxy-beta-methylbutyrate (HMB) is a natural metabolite of the amino acid leucine that helps stimulate muscle protein synthesis and reduce muscle breakdown.
Key Benefits of HMB
Reduces Muscle Breakdown: Blocks the ubiquitin-proteasome pathway to stop muscle protein degradation during stress, fasting, or intense exercise.
Boosts Muscle Synthesis: Activates the mTOR pathway to encourage new muscle tissue growth.
Supports Older Adults and Sarcopenia: Helps older adults and individuals facing age-related muscle loss maintain lean body mass and strength.
Improves Recovery: Lowers markers of exercise induced muscle damage and speeds up recovery times after hard workouts.
Enhances Exercise Adaptation: May increase strength performance and fat free mass, particularly in untrained individuals or when combined with resistance training.
