How the numbers are made
We read each product’s label – mostly from the NIH Dietary Supplement Label Database, matched by barcode – and work out what one fixed dose costs, for example 5 g of creatine or 1,000 mg of EPA + DHA. Prices come from the brands’ own US shops and US retailers and are checked again every week. The full method, and what we leave out, is on How we check.
We compare prices and label facts only. We don’t say what a supplement does for your health, and no brand or shop can pay for a better spot.
