How are Homocystein and menopause related?

Homocysteine and menopause are linked via estrogen decline. Estrogen supports the activity of enzymes (e.g., CBS, MTHFR) that metabolize homocysteine. After menopause, estrogen drops, often leading to increased homocysteine levels. Elevated homocysteine is an independent risk factor for cardiovascular disease, which rises postmenopause. Studies show moderate associations but not strong causality. Supplementation with folate, B12, and B6 lowers homocysteine but, in randomized trials, does not significantly reduce cardiovascular events. Genetic variants (e.g., MTHFR C677T) influence homocysteine levels, but clinical relevance for menopause is limited. MyBody-X DNA tests may analyze such variants, but the utility for individual therapy is unclear. A homocysteine test after menopause can be useful but should always be interpreted in a medical context. Evidence: human-moderate. Caveat: No randomized trials show that lowering homocysteine via supplements reduces cardiovascular mortality.
