Beta-Hydroxy-Beta-Methylbutyrate (HMB) & Leucine: The 2026 Orthomolecular Sarcopenia Protocol
Beta-Hydroxy-Beta-Methylbutyrate (HMB) & Leucine: The 2026 Orthomolecular Sarcopenia Protocol
How active leucine metabolites suppress ubiquitin-proteasome proteolysis, protect sarcolemmal integrity, and maintain nitrogen balance during midlife aging.
Scientific Methodology: 3-methylhistidine urinary excretion assays, fractional muscle breakdown rates, and randomized controlled trial endpoints verified as of October 2026.
1. The Anti-Catabolic Power of HMB (Free Acid vs Calcium Salt)
While leucine stimulates muscle protein synthesis, its endogenous downstream metabolite—Beta-Hydroxy-Beta-Methylbutyrate (HMB)—exerts potent anti-catabolic effects by inhibiting the ubiquitin-proteasome pathway. Only ~5% of dietary leucine is naturally converted to HMB, making direct supplementation essential during caloric deficits or periods of physical rehabilitation.
