HMB (Beta-Hydroxy Beta-Methylbutyrate)

Definition

HMB is a compound that helps to prevent the breakdown of muscle proteins, often used as a supplement to enhance physical performance.

Scientific / Technical Definition

Beta-Hydroxy Beta-Methylbutyrate (HMB) is a metabolite of the amino acid leucine and is known for its role in reducing muscle protein breakdown and promoting muscle growth and repair. It can aid in muscle recovery and improve athletic performance, particularly in resistance training.

Benefits

• Reduces muscle breakdown
• Enhances muscle growth
• Improves recovery time
• Aids in muscle repair
• Potentially enhances endurance performance

Examples

• HMB supplements in capsule or powder form
• HMB can also be synthesized from leucine, found in foods like meat, fish, and eggs

Additional Information

• effects: HMB aids in reducing muscle damage from intense exercise and might also boost strength gains during resistance training.

Related Terms

• Leucine
• Amino acids
• Muscle protein synthesis
• Creatine
