The Supplement Ratings

About The Supplement Ratings

An independent project that scores 116,409+ supplement labels. No sponsors. No pay-to-play. Just public data.

Why This Exists

I started this project because I was frustrated. Every time I tried to find a good supplement, I'd end up on a "Top 10 Best" list that was clearly paid placement. Reviews felt fake. Labels were confusing. Proprietary blends hid ingredient amounts behind marketing jargon.

So I built something different: an algorithm that scores supplements based entirely on their label data — no opinions, no sponsorships, no brand deals. The data comes from the NIH Dietary Supplement Label Database (DSLD), a public government database with label information for over 116,000 dietary supplements sold in the US.

How It Works

Every product gets a SupplementScore from 0 to 100, calculated across four categories:

Dosage Transparency 35 pts

Does the label disclose individual ingredient amounts, or hide behind proprietary blends?

Label Completeness 25 pts

Are all required fields present — serving size, daily values, allergen warnings?

Formulation Cleanliness 25 pts

How many fillers, artificial colors, and unnecessary additives are in the "Other Ingredients"?

Ingredient Profile 15 pts

Are the active ingredients backed by published research? What evidence level exists?

The score evaluates label quality — not clinical efficacy. A high score means a transparent, clean, well-documented product. It does not mean the product will work for you. Read the full methodology
