Registry check · HMB
Does anyone independently verify HMB supplements?
Not one of these 6 products is listed by NSF, USP or Informed Sport as a verified product. Yet 3 of them advertise “third-party testing” without naming the certifier that did it — wording no public registry can confirm or deny. A factory-level claim such as “cGMP” audits the plant, not the HMB bottle you would actually receive.
6 checked against all 5,317 US NSF, USP and Informed Sport listings, 2026-08-25. Full method and limitations.
What 6 HMB labels show
Priced per day, these HMB products run $0.28 to $1.50 — a 5.4× gap between the cheapest and dearest HMB here, across 5 brands.

What the published reviews of HMB concluded
- Ergogenic Benefits of β-Hydroxy-β-Methyl Butyrate (HMB) Supplementation on Body Composition and Muscle Strength: An Umbrella Review of Meta-Analyses. · Journal of cachexia, sarcopenia and muscle, 2025
“HMB supplementation may benefit individuals experiencing muscular atrophy due to physiological conditions, particularly enhancing muscle mass and strength without significant changes in fat mass or body weight.”
- The Role of HMB Supplementation in Enhancing the Effects of Resistance Training in Older Adults: A Systematic Review and Meta-Analysis on Muscle Quality, Body Composition, and Physical Function. · Nutrients, 2025
“HMB supplementation combined with RT may yield modest improvements in functional performance, particularly handgrip strength and overall physical function, without statically significant effects in body composition and MQ.”
- Effects of multicomponent training and HMB supplementation on disability, cognitive and physical function in institutionalized older adults aged over 70 years: a cluster-randomized controlled trial. · The journal of nutrition, health & aging, 2024
“The Vivifrail exercise program was effective in improving cognitive and physical function, and muscle power in nursing home residents, while HMB supplementation did not provide additional benefits when combined with exercise.”
- Effects of acute HMB-FA supplementation on antioxidant status and muscle damage in Elite Judoka: a randomized pilot trial. · Journal of the International Society of Sports Nutrition, 2026
“Acute post-exercise HMB-FA supplementation in elite judo athletes did not significantly influence muscle damage or oxidative stress markers but transiently increased antioxidant enzyme activities (CAT, GPX, and SOD).”
Method: PubMed searched in humans for systematic reviews, meta-analyses and randomised trials with HMB in the title; these 4 of the 7 that qualified are shown with the authors’ own conclusion quoted rather than summarised. What it cannot tell you: whether HMB will work for you — each of these reports an average across trials published 2024–2026, and null findings are shown here as readily as positive ones.
How these 6 HMB products were ranked
Not one of these 6 HMB products could be confirmed in the NSF, USP or Informed Sport registries, so verification separates none of them and the ranking falls to cost per day at the labelled serving. Commission does not enter it: the rate is the same whichever HMB you buy. Full methodology.
