Supplement Brand Rankings: Reviewed Evidence and Coverage

A useful brand ranking starts with enough reviewed evidence to compare the brands. We publish a score only after current certification and regulatory coverage meet our evidence requirements.

Can we publish a top 50?

Of 7882 brands in this directory, 0 currently qualify for a published evidence score. We show up to 50 eligible brands below. We do not fill missing places with historical scores or treat an unreviewed brand as a low-scoring brand.

No complete brand reviews currently qualify for a ranking. Product-level records remain available below. Those records answer narrower questions and do not establish a comprehensive brand rating.

What qualifies a brand for this comparison?

1. Source identity: evidence must belong to the correct brand and identify the source checked.
2. Product scope: certification records must identify the products and variants they cover.
3. Coverage: certification and regulatory reviews must both be complete under the documented method.
4. Freshness: accepted checks must be current at the evidence snapshot’s stated date.

When a review is incomplete, we show that limit rather than awarding points for assumed certifications or subtracting points for missing information. A recorded zero from a scoped source search is not a guarantee that no incident has ever occurred.

Retailer links may earn us a commission and may open a broad brand catalog. Match the chosen product to the reviewed name, formulation, flavor, region and listed lot before buying.

How to use a future ranking

Open the brand’s evidence record rather than relying on its position. Check which components contribute to the score, which facts are excluded and when the source searches took place. Two equal scores can result from different evidence, so the number should not replace the underlying comparison.

A certification on a sports powder may be useful for that purchase and irrelevant to the same brand’s vitamin or fish oil. Follow the category guides for creatine, protein powder and fish oil to keep the comparison within a product category.
