Why this scored 61/100
Standalone MSM SKU. Kim 2006 and Debbi 2011 support MSM at 1500-6000 mg/day for modest OA symptomatic relief. Generic Swanson sourcing, no OptiMSM callout, and no per-cap dose in title. Held below Verified by lack of purity certification. Would move to Verified 70+ with named-source (OptiMSM) and third-party COA.

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.
Frequently asked questions
Auto-generated from Vyvata's scoring data for this product. For general questions about the store (shipping, returns, wholesale), see the site FAQ.
What is MSM?
MSM, categorized under Joint, bone & connective tissue health in the Supplements vertical. It is scored on the Vyvata Scoring Framework — an independent 6-dimension rubric applied uniformly to every product Vyvata lists.
How does MSM score on the Vyvata rubric?
61/100 overall — Standard tier (50–69 band). Per-dimension breakdown: Safety 68, Evidence 63, Formulation 62, Manufacturing 60, Transparency 58, Sustainability 52. Scored as of 2026-08-24.
Why did MSM score in the Standard tier?
Standalone MSM SKU. Kim 2006 and Debbi 2011 support MSM at 1500-6000 mg/day for modest OA symptomatic relief. Generic Swanson sourcing, no OptiMSM callout, and no per-cap dose in title. Held below Verified by lack of purity certification. Would move to Verified 70+ with named-source (OptiMSM) and third-party COA.
What are the strongest and weakest aspects of this product?
Strongest: Safety at 68/100 (adverse-event profile, interaction risk, and dose ceiling) and Evidence at 63/100 (quality of published RCT support for the active ingredients at the label dose). Weakest: Transparency at 58/100 (dose disclosure vs proprietary blends, and honesty of marketing claims) and Sustainability at 52/100 (sourcing practices, packaging, and corporate practice). All six dimensions feed the overall Vyvata score; a weakness on any one dimension pulls the overall down proportionally.
Is MSM third-party tested?
No third-party certifications (NSF, USP, ConsumerLab, or equivalent) were on record at the time of scoring. This affects the Manufacturing dimension score. The manufacturer may test internally or have obtained certification more recently — check the current product label for the most up-to-date information.
