Myths vs facts: MTHFR and menopause

Myths vs. facts about MTHFR and menopause: Online claims suggest that MTHFR variants (e.g., rs1801133) worsen menopause symptoms like hot flashes or mood swings, or that special supplementation is required. The scientific evidence for these claims is weak. MTHFR is an enzyme in folate metabolism; reduced activity can affect homocysteine levels, but a direct causal link to menopausal symptoms is not supported by robust studies. Many so-called 'facts' stem from overinterpreted associations or marketing. The reality: MTHFR variants are common (about 30–40% of the population carry one) and typically have a small effect. Standard folate intake (400 µg/day) is usually sufficient; high-dose folic acid can mask vitamin B12 deficiency. For menopause symptoms, evidence-based approaches like hormone therapy or lifestyle changes are better studied. A DNA test alone should not drive treatment decisions. Consult a doctor before altering supplements.
