Judge supplements by the numbers

Enter price, servings and dose — see real cost per serving, per year, and per gram of active, and compare up to three products. The cheapest sticker isn’t always the cheapest dose.

Pick an ingredient, enter what your product delivers per serving, and see whether it’s below, within, or above the dose studies actually used — with a visual scale and safety-limit flags.

Answer six questions off the Supplement Facts panel and get a transparency score, the specific green flags and red flags, and what they mean — before you pay. A label check, not a substitute for a full review.

Enter a blend’s total weight and how many ingredients it lists, and see the most any single one could contain — and how little. The math a proprietary blend hopes you never do.
