About

Supplement Label Index analyzes the entire US dietary supplement market as declared on labels submitted to the NIH Dietary Supplement Label Database (DSLD) — 121,959 on-market products from 5,801 brands, as of our latest dump. Think census bureau for supplement labels, not product review site.

What this site is

• Market-level analytics: form share, dose distributions, excipient prevalence, brand-level patterns, trends over time.
• Built entirely from what manufacturers declare on their own labels to a public federal database.
• Updated monthly as DSLD publishes new dumps.

What this site is not

• Not a product review or ratings site — we don't score, rank, or recommend individual products.
• Not health or nutritional advice — see a qualified healthcare professional for guidance on your own supplementation.
• Not a claim that any product is safe, effective, or FDA-approved — dietary supplements are not FDA-approved before sale.

Who reads this
