BioStacksHow HMB supports muscle
HMB plays a supporting role in muscle. Meta-analyses (Nissen & Sharp 2003, Wu et al. 2015) demonstrate benefits for lean mass preservation, particularly in untrained individuals and older adults. In clinical studies, hmb supports lean muscle mass preservation (meta-analysis).
Effective dosing
Most evidence supports 1000–1500 mg of hmb daily. Per-dose range: 1–1.5 g (daily total 3 g split across 3 doses). Most capsule products deliver 1 g/serving. Both calcium HMB and free acid forms studied; free acid may have faster absorption. Products below this range may not deliver meaningful results.
Clinical research
HMB has moderate clinical evidence for muscle benefits. Meta-analyses demonstrate lean mass preservation benefits, especially in untrained and older adults Learn more
