The SupplementData Center

What 202 products across 20 substances actually tell us.

Aggregated across every product in every dataset we maintain — the sponsored picks for our own products are excluded, so these are the independent market numbers. Each figure is computed live from the underlying per-product scores; nothing here is hand-entered.

Which categories you can actually trust.

Each substance ranked by the median Transparency Index™ of its products — third-party certification (0-50) + public batch COA (0-30) + dose honesty (0-20). The gap between the most and least transparent categories is the single biggest reason a buyer needs a map.

Best value vs priciest categories.

The real price of one clinical dose — not one marketed “serving” — by substance. Categories are ranked by median Cost-Per-Effective-Dose™; the dose each is measured against is shown beneath the name so a $0.20 dose and a $2 dose are read in context.

The full data table.

Every substance we maintain a dataset for, with the median of each proprietary index across its products. Sorted by median SAC Product Score™. Open any row for its full Market Report — the per-product leaderboard and methodology behind these medians.

Methodology. SAC Product Score™ blends our editorial rating (RCT quality, dose, safety, value) 50/50 with community ratings, on a 0-10 scale. The Transparency Index™ (0-100) = third-party certification (0-50) + public batch COA (0-30) + dose honesty (0-20). Cost-Per-Effective-Dose™ is the real price of one clinical dose, not one marketed serving. Each figure above is the median across that substance’s reviewed products.
