For everyone, adults.
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.

    We read the label.

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

  2. 02
    Every active, separately.

    All 1 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.
