The short answer

**Do** evidence-based folate habits; **don't** build your identity around common SNPs. See [myths debunked](https://healthcanon.com/hormones-and-genes/best-mthfr-myths-debunked-2026) and [nutrition actions](https://healthcanon.com/hormones-and-genes/best-mthfr-nutrition-actions-2026).

Common MTHFR variants are frequent; rare severe deficiency is not what DTC ads usually sell.
