Who we are and how our reports are built

Who we are

Fuel Your DNA is published by FuelYourDNA, an independent sole proprietorship based in Pornichet, France, registered since 2009. We are not a laboratory: we do not sell DNA kits and we never take samples. We read the file you downloaded from your provider (23andMe, AncestryDNA, MyHeritage, FamilyTreeDNA, LivingDNA and others). Full company details are in the legal notice.

How a report is built

• A fixed panel of 123 variants in 100 genes, each chosen because published studies link it to how people handle nutrients, caffeine, lactose, lipids, iron, vitamins or exercise.
• The same written rules turn each genotype into a result and practical advice, for every customer. Each notable result lists the scientific references behind it.
• One section of the reports is an overall interpretation written by an AI model (Claude, by Anthropic) from your results. It is labelled as such, and it never replaces the rule-based results.
• When a variant is missing from your file, the report says that the gene is not covered by your chip. It never guesses.

What we will never do

• Sell your genetic data.
• Give a diagnosis, or tell you to start, stop or change a medication.
• Promise weight loss or results that the evidence does not support.

The limits, honestly

A consumer chip reads common variants, not your whole genome, and most genetic effects on nutrition are modest compared with what you eat, how you sleep and how you move. Genes are most useful when they change the advice itself: lactose, caffeine, folate and B12, vitamin D. We explain how we read the evidence in our articles, including a guide to judging a nutrigenetics study.

Your data

The free test reads your file in your browser: it is never sent to us. For a paid report, the file is used to build the report and then deleted. Payments go through Stripe or PayPal, and we never see your card number. Everything is detailed in our privacy policy.
