How are MTHFR and menopause related?

The relationship between MTHFR variants and menopause is not clearly established in the scientific literature. MTHFR is a key enzyme in folate and homocysteine metabolism; common variants like C677T can reduce enzyme activity and elevate homocysteine levels. After menopause, cardiovascular risk increases naturally, and elevated homocysteine is an independent risk factor. Some observational studies have suggested associations between MTHFR polymorphisms and earlier age at menopause or more severe vasomotor symptoms (hot flashes), but the evidence is weak and inconsistent. No strong clinical recommendations exist for using MTHFR genotyping to predict menopause timing or symptoms. A more evidence-based approach is to measure blood homocysteine and folate levels, especially in women with known MTHFR variants. Adequate folate intake (preferably as methylfolate) may help lower homocysteine, but this should be discussed with a healthcare provider. Overall, the link is plausible on a mechanistic level but lacks robust human data for clinical decision-making.
