HMB is a metabolite of the essential amino acid leucine, known for its role in promoting muscle protein synthesis and reducing muscle breakdown. It is naturally produced in the body in small amounts and is popular in the supplement industry for its muscle-preserving effects.
Athletes and individuals involved in resistance or endurance training often use HMB to support muscle mass retention, especially during periods of intense training or caloric restriction.
It has been studied for its ability to reduce muscle damage, enhance recovery, and possibly increase strength and performance. HMB is most effective when combined with consistent resistance training and adequate protein intake.
Synonyms:
β-Hydroxy β-Methylbutyrate
Benefits:
- Reduces muscle protein breakdown
- Aids in muscle preservation during intense training
- May enhance strength and lean body mass
- Supports faster recovery after exercise
Sources:
Synthesized in the body from leucine; available as a supplement in free acid or calcium salt forms.
Observations:
Commonly found in capsules and powders. Generally well tolerated; high doses may cause minor digestive discomfort.
