20 questions about how you eat and how you live, scored against 49 published risk factors drawn from 10 NIH reference sources. You get a ranking — and next to every line, the reason it is there and where that reason comes from.
We ask for your email first, so your result can be found again later. No account, and the mailing list is a separate tick-box you can leave alone.
Everything below is inferred from what you tell us about your diet, your sunlight and your medicines — the same reasoning a dietitian applies at a first appointment. Only a blood test can tell you your actual status, and where that matters we will say so rather than pretend otherwise.
Before we start
Your ranking is worked out from your answers and kept at a private link. We store your address with it so the result can be found again and so we can reach you about it. You will see the ranking as soon as you finish — nothing waits on an email arriving.
20 questions, about 3 minutes. No account, and nothing is charged.
Ten nutrients ordered by how much your answers argue for each one — not an alphabetical checklist.
Each reason links to the NIH fact sheet it rests on, so you can check us rather than trust us.
The foods that fix each gap come first. A supplement is what you reach for when food has not worked.
