What it is
HMB (Beta-Hydroxy Methylbutyrate) is a metabolite of the amino acid leucine. It is utilized to support muscle protein synthesis and reduce muscle protein breakdown, particularly relevant during periods of intense physical training.

How it works
HMB functions by inhibiting the muscle protein breakdown pathway (ubiquitin-proteasome pathway) and stimulating the muscle protein synthesis pathway (mTOR pathway). This dual action helps preserve muscle mass and promote muscle repair.
Who should take it
Adults looking to address joint stiffness, muscle weakness, joint pain. Particularly relevant for people who prefer a targeted single ingredient and who have ruled out an underlying condition that needs medical care first.
Avoid / careful
Pregnant or nursing women without clinician oversight. People on prescription medication affecting the same pathway should consult a doctor before combining. Side effects are uncommon at recommended doses but mild GI upset can occur when starting.

FAQs
Frequently asked
What is the primary benefit of HMB?
HMB's primary benefit is its ability to reduce muscle protein breakdown, which aids in muscle recovery and preservation of lean muscle mass.
How long does it take to see results from HMB?
Visible benefits, such as reduced muscle soreness and improved strength, typically emerge after 4-12 weeks of consistent daily use.
Can HMB be taken with other supplements?
Yes, HMB can be effectively combined with other supplements like creatine, whey protein, and BCAAs to enhance its muscle-supporting effects.

About HMB (Beta-Hydroxy Methylbutyrate)
HMB (Beta-Hydroxy Methylbutyrate) is a athletic recovery & performance supplement used to support joint and musculoskeletal health. Leucine metabolite to reduce muscle breakdown. It is available in capsule form and dosed for adults in India and internationally. As a western-tradition entry in the SacredBod catalog, it is positioned as a single-ingredient option that can be used on its own or layered into a broader protocol. HMB (Beta-Hydroxy Methylbutyrate) works through the mechanisms characteristic of its class — see the mechanism and research sections for detail. It primarily acts on the joints, muscles, bones, and effects are dose-dependent, typically becoming measurable within 4-12 weeks for joint comfort. Consistency matters more than dose size for this category.
Evidence
HMB (Beta-Hydroxy Methylbutyrate) carries an evidence grade of B in the SacredBod catalog, reflecting good-but-limited human evidence for joint and musculoskeletal health. Leucine metabolite to reduce muscle breakdown. Benefits are cumulative rather than immediate, typically becoming noticeable within 4-12 weeks for joint comfort, and individual response varies.
Dosing
A typical dose is 1000 mg, taken with food, usually in the morning. Start at the lower end, assess tolerance, and stay consistent; more is not automatically better.
Cautions
Pregnant or nursing women without clinician oversight. People on prescription medication affecting the same pathway should consult a doctor before combining. Side effects are uncommon at recommended doses but mild GI upset can occur when starting.
