Shoppers
Check a label before you buy.
Paste the label from the pack or the product page, or type a single ingredient. See which claims the research backs before you spend.
- A plain verdict for every claim on the label, from “Likely to work” to “Unlikely to work”.
- The ingredient behind each answer, with the trials and reviews it rests on.
- What users say: the doses people report, how it went and the side effects they mention, labelled as self-reported.
- Whether the dose on the label is below, inside or above the range people report.
Brands and retailers
Check label claims against the research before you publish.
Paste draft label copy or a product description. Each claim is tied to its ingredients and checked, so weak or untestable wording shows up before customers see it.
- Each claim matched to the ingredients it is about, and checked for each one.
- Wording that names nothing measurable is marked “Too vague to check”.
- The kinds of study behind each answer: reviews that combine studies, trials in people, observational and lab studies.
- Quotes from the studies we read, shown only when they match the paper word for word.
Pharmacists, nutritionists and coaches
A quick evidence summary to share with a client.
Type an ingredient to open its profile: what it is studied for most, how much research there is, and how strong that research is.
- Research totals for each ingredient, with clinical trials in people and reviews that combine studies.
- What each ingredient is studied for most, ranked by strong findings rather than by how many papers exist.
- Plain verdicts a client can follow without a science background.
- A clear line between published research and what users report.
