Supplement test results
What public sources have printed about a supplement bottle, each figure linked to the document that printed it, and the gaps left in. We test nothing ourselves.
Records retrieved Oct 23, 2026 6,200 bottles 8 public sources
The short answer
1,798 bottles scored- Most supplements have no public lab numbers. Of 1,798 bottles in the scored release, 42 have a printed measurement; 1,746 are certification listings and nothing else.
- A listing means a certifier named the bottle. It is a status, not a result: no potency, no metals, no lot.
- Vitamin D: 4 of 77 bottles have a printed result or a recall, side by side with their documents.

Score against coverage
Each dot is a scored bottle. Coverage is how much of the rubric its public record let us score, so a high dot on the left is a thin record, not a winner.
