Why this scored 62/100
Nutrex Research HMB 1000 delivers 1000 mg calcium HMB (beta-hydroxy-beta-methylbutyrate) per serving in vegetable capsules, 60 servings per bottle. HMB is a metabolite of leucine with real ingredient-level evidence for reducing exercise-induced muscle protein breakdown, supporting recovery, and preserving lean mass during caloric deficit. Meta-analyses (Wilson 2013, Rowlands 2009) show consistent modest effects on lean mass preservation particularly in untrained subjects and older adults. The classic studied protocol is 3 g/day (typically split as 3x1g), so 1000 mg per serving matches one dose of the studied 3x1g protocol. Nutrex is a real US sports-nutrition brand with mass-retail distribution. Class-level evidence and disclosure profile are Standard-tier. Held from Verified by absence of Informed Sport / NSF Sport certification and by product-level marketing being reasonable rather than exceptional. Solid entry.

Evidence & sources
The Vyvata score's Evidence dimension measures the quality of published RCT support for a product's active ingredients at the label dose. Our source hierarchy: double-blind RCTs in MEDLINE-indexed journals > single-blind RCTs > open-label trials > observational studies > mechanism papers > N=1 case studies (anecdotes). Predatory journals and manufacturer-authored studies without independent replication are weighted down.
Product-specific evidence citations for this item are embedded in the analysis text on the "Analysis" tab. For the full framework and evidence hierarchy, see the methodology page.
How to read the Evidence dimension
- 80–100: Multiple double-blind RCTs in indexed journals directly testing this product OR the exact ingredients at the exact dose.
- 60–79: Single double-blind RCT + supporting ingredient literature at the studied dose.
- 40–59: Open-label trials + ingredient literature; no product-specific double-blind evidence.
- 20–39: Ingredient literature only; no product-specific trials or trials in predatory venues.
- 0–19: No credible evidence base or unverifiable claims.
