Supplement Brand Analysis: What Our Evidence Covers
Last updated:
A directory is not the same thing as a completed evidence review. This page shows the coverage of the reviewed records we can publish and the conclusions those records cannot support.
Current coverage
Brands in the directory
Brands with reviewed product records
Reviewed product-certification records
Brands eligible for an evidence score
A product may have more than one record, and a record may describe a specific flavor or market. The record count is not necessarily a count of unique products. The figures are a snapshot of this site’s review, not an estimate for the entire supplement industry.
Regulatory count coverage
| Record type | Brands with a reviewed count | Not yet established |
|---|---|---|
| FDA recalls | 0 | 7882 |
| FDA warning letters | 0 | 7882 |
| FDA adverse-event reports | 0 | 7882 |
| Health Canada recalls | 0 | 7882 |
A reviewed count needs the source search, date and scope that produced it. Unreviewed counters do not enter this table as confirmed incidents or confirmed zeroes. Warning letters, recalls and adverse-event reports remain distinct record types.
What these numbers do not show
- How many brands never test: absence of a reviewed certification cannot establish absence of testing.
- A clean safety history: missing incidents or incomplete searches do not establish one.
- Population-wide safety: our directory is not a representative sample designed for that inference.
- Clinical risk: an editorial evidence score is not a medically validated risk estimate.
- Whether price predicts quality: that would require a separate, defined price and product study.
Why we withhold scores
Specific product records can be checked while broader brand coverage remains incomplete. Publishing an average or grade distribution from historical unchecked scores would hide that difference. We publish a score only when both certification and regulatory review requirements are met; remaining brands stay unrated.
How the review becomes more useful
Each accepted record should make a narrower, traceable claim: a source, observation date, brand identity and product or search scope. Review can then expand to additional products, programs and regulators without making an old boolean flag look like a new verification.
Corrections and new evidence can change a record without proving that the underlying product itself changed. When comparing snapshots, inspect the documented source and reason for the revision rather than treating every score movement as an improvement or deterioration in manufacturing.
