Nutrigenomics¶
Not a medical test — for research and educational use only
Yeliztli analyses consumer genotyping-array data (23andMe / AncestryDNA), which is not a clinical-grade test. Results are not diagnostic, are not clinically validated, and must not be used to make medical decisions. Array data is especially unreliable for rare, disease-causing variants. Always confirm any finding with an accredited clinical laboratory and discuss it with a qualified clinician or genetic counsellor before acting on it. See the Intended use & disclaimers page for the details and the evidence behind this warning.
Nutrigenomics gives a categorical read on a handful of nutrient-metabolism pathways. It reports tendencies, never numeric risk scores or dietary prescriptions.
What it looks at¶
17 curated SNPs across seven pathways:
- Folate metabolism (MTHFR C677T/A1298C, MTRR)
- Vitamin D (GC, CYP2R1)
- Vitamin B12 (FUT2)
- Vitamin B6 (ALPL)
- Omega-3 (FADS1, FADS2)
- Iron metabolism (HFE C282Y/H63D)
- Lactose tolerance (MCM6/LCT)
What you'll see¶
A level per pathway — Elevated need, Moderate need, or Standard — with a per-SNP breakdown showing your genotype, the effect, an evidence rating, and supporting citations.
Good to know¶
- Elevated requires at least 2-star evidence plus a meaningful genotype; weaker (1-star) variants are capped at Moderate.
- Some markers are population-specific (e.g. the lactose-tolerance variant is informative mainly in European and South-Asian ancestries) and carry an ancestry caveat.
- These are tendencies, not deficiencies — a blood test is the way to actually measure a nutrient level.
