How we verify

The brand submits the formula. We read the supplement facts panel and weigh dose, form and synergy against the clinical evidence. Labs test. IngredientMD verifies. The fee pays for review time, never for the outcome.

    The panel on the left is the one we evaluated, line by line.

    Every active, separately.

    All 2 actives checked against the clinical evidence: dose, form, and what the research actually shows.

    Then the formula as a whole.

    Doses, ratios, and how the ingredients work together. That assessment is the verdict above: "Strong evidence, strong dose".

  4. 04
    Earned, not bought.

    The verdict is public and identical whether or not a brand pays. A formula that does not clear the bar gets nothing.

What the trials show

What the trials show about timing.

Time-to-effect windows the engine read from the trial record. Each is a window a named study measured, cited and dated, never written by the brand.

  • Curcumin C3 Complexmore than ten weeks of daily useBuilds with daily use

    A meta-analysis of randomised trials pooled nine trials for C reactive protein and 23 for high sensitivity C reactive protein in proinflammatory conditions. Pooled CRP fell by a weighted mean of 3.67 mg/L against placebo, and the subgroup analysis placed that fall in interventions running longer than ten weeks, with the high sensitivity CRP effect appearing in trials of ten weeks or less and at doses at or under 1,000 mg a day. An earlier meta-analysis of 19 trials in chronic inflammatory disease, with follow up of 4 to 16 weeks, found no significant change in CRP, hsCRP, IL-6 or TNF alpha. Heterogeneity was high across both reviews, and the measure is a blood marker rather than a symptom.
