Your DNA changes what your body needs from food and supplements. We write about the genes we test, the nutrients they affect, and where the science is solid versus where it's still messy. No hype, no miracle claims.
Nutrigenomics
Every label lists a dose calculated for someone with average absorption and average genetics. That person doesn't exist. Here's what your variants actually change.
Nutrigenomics
Around 40% of people carry a variant that slows how they turn folic acid into usable folate. Here's why the form on your label matters more than the dose.
Trust & standards
DNA diet tests are everywhere and the rules haven't caught up. A 2025 review named five markers of a credible programme. Here's the checklist.
Nutrigenomics
One gene — CYP1A2 — determines whether caffeine clears in 3 hours or stays in your system until midnight. Your tolerance isn't weak. It's genetic.
Nutrigenomics
Deficiency despite supplementing is often a VDR receptor problem, not a dose problem. Reduced-function variants need 2–3× as much to achieve the same cellular effect.
Nutrigenomics
Red wine headaches. Bloating after aged cheese. Flushing after fermented food. The DAO gene determines how fast your gut clears histamine — and whether it builds up.
Performance
ACTN3 encodes the only protein found exclusively in fast-twitch muscle fibres. One variant determines whether you make it at all — and tilts your physiology toward power or distance.
Nutrigenomics
FTO, ADRB2 and PPARG shape hunger signalling, fat mobilisation and where your body stores fat. They explain why identical diets produce completely different results.
