How to prepare for MTHFR Alltag

Preparing for everyday life with an MTHFR variant requires a realistic perspective: Most MTHFR polymorphisms (e.g., C677T) have only a small effect on methylation and homocysteine levels. Direct-to-consumer tests often overstate their clinical significance. A balanced diet rich in green vegetables, B vitamins (folate, B6, B12), and possibly a blood test for homocysteine and vitamin levels is sensible. Supplementation with methylfolate is not automatically necessary – it may be indicated for high homocysteine or certain risk groups (e.g., pregnancy), but the evidence is mixed. Without medical guidance, high-dose supplements should be avoided. Lifestyle factors (exercise, stress, sleep) usually have a greater impact than genetics alone.
