Why this scored 55/100
Curcumin is the primary polyphenol in turmeric (Curcuma longa) with a substantial evidence base for anti-inflammatory effects at high doses. Meta-analyses show meaningful effects on inflammatory markers (Sahebkar 2016), knee osteoarthritis pain (Daily 2016 vs NSAIDs), depression (Ng 2017), and lipid parameters. The critical issue with plain curcumin capsules is bioavailability — free curcumin has <1% oral bioavailability without a delivery enhancer. Piperine (from black pepper) at 5-20mg increases curcumin bioavailability up to 20x (Shoba 1998); other enhanced forms include Meriva (phytosome), BCM-95, Longvida (nanoparticle), and Theracurmin. Plain turmeric powder or raw curcumin without a bioavailability enhancer will be largely unabsorbed. This SKU discloses 'curcumin turmeric powder' without piperine, bioavailability enhancer, or per-capsule mg. Standard 55/100: real ingredient with real evidence for high-dose use, held down by likely poor bioavailability (no enhancer disclosed), no dose, no 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.
