Calcium β-hydroxy-β-methylbutyrate (HMB)

Calcium β-hydroxy-β-methylbutyrate (HMB-Ca) is the active metabolite of leucine. It inhibits muscle protein breakdown and promotes muscle protein synthesis. Widely used in sports nutrition and for supporting muscle health in older adults, HMB helps reduce post-exercise muscle damage and slows sarcopenia.

Market Outlook

The global HMB supplement market was valued at approximately 2.5 billion USD in 2026, with a CAGR of about 8.2%. While HMB is already well-established in sports nutrition, demand is surging in the senior health category as sarcopenia gains attention. Clinical studies show that daily intake of 3g HMB significantly improves muscle mass and strength in older adults.
