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.

How we read this product

Source: Supplement facts
Supplement Facts panel for Green Superfood Original
  1. 01
    We read the label.

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

  2. 02
    Every active, separately.

    All 6 actives checked against the clinical evidence: dose, form, and what the research actually shows.

  3. 03
    Then the formula as a whole.

    Doses, ratios, and how the ingredients work together. That assessment is the verdict above: "Backed by human trials".

  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.

Read by the engine against 2.1 million data points from clinical trials, PubMed and more than a hundred vetted sources. No individual reviewer is named or implied.

General timing

How each ingredient usually behaves over time.

Six ingredients, from each one's own page.

  • Green Food Blend

    There's no acute effect. It contributes nutrients day by day, and the fibre and vitamin K1 side shows up in regularity and on a panel across a few weeks.

    Its own page, the plain answer on timing

  • Antioxidant Blend

    There's no acute effect here. The antioxidant and vascular markers followed in studies shift over roughly four to eight weeks of daily use, which is where the change shows up.

    Its own page, the plain answer on timing

  • Fiber Blend

    The fibre side acts on the meal it's taken with, so fullness can shift the same day. Regularity settles over two to three weeks, and lipid markers over about a month.

    Its own page, the plain answer on timing

  • EFA Fiber BlendWithin two to three days

    Stool bulk and regularity usually shift within two to three days. Blood lipid and glucose markers move on a slower clock, over roughly four to twelve weeks of daily use.

    Its own page, the plain answer on timing

  • Digestive Enzyme Blend

    They act on the meal they arrive with, so comfort after that meal is the first thing you notice, usually within an hour or two.

    Its own page, the plain answer on timing

  • Probiotic BlendAbout two to four weeks

    Give it two to four weeks of daily use. Adaptogen trials read their stress and fatigue measures at four to eight weeks, not on day one.
