Type the name on the label, the chemical name, the abbreviation, or whatever people call it at the gym. They all lead to the same record.
16,099 substances · seven public registers · 100 graded so far
Names are a mess. One substance can carry a chemical name, a brand name, an abbreviation and half a dozen nicknames. Type any of them and you land on the same record, with a source for why that name was accepted.
Every record says which of seven public registers list the substance — among them the US Food and Drug Administration, the Drug Enforcement Administration and the European Medicines Agency — and whether it is controlled. Listed nowhere is an answer too.
For 100 substances so far, the published research has been read and summarised in plain words. Where the studies stated an amount, the record also shows how that amount compares with what is actually declared on the products for sale. The other 15,999 are listed as a record of the register entry and nothing more.
Two different numbers, and nobody usually prints them next to each other. Counted for 12 substances against 18,611 product labels currently on sale in the United States.
Amounts from the NIH Dietary Supplement Label Database, retrieved 2026-08-09. Counted the way most generous to the product, taking the largest daily serving each label itself suggests. No product is named, and none of this is a recommendation to take any amount.
Every grade here is provisional and carries a methodology version. Records get regraded when the evidence moves, and the reviewer who will sign them has not been appointed yet. If you want to be told when either happens, leave an address.
