Which nutrients is your diet actually short of?

19 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.

This estimates your intake. It does not measure you.

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.

About you

Requirements differ by age and life stage more than by anything else you will tell us.

How old are you?

Reference intakes are published in age bands, and two of them change what we may suggest at all.

Which reference intakes should we use?

Published reference intakes are split by sex assigned at birth — iron and calcium differ most. Nothing here is an assumption about your gender.

No account, and no email needed to see your result.

Ranked, not listed

Ten nutrients ordered by how much your answers argue for each one — not an alphabetical checklist.

Every line is sourced

Each reason links to the NIH fact sheet it rests on, so you can check us rather than trust us.

Food before pills

The foods that fix each gap come first. A supplement is what you reach for when food has not worked.
