The best supplements for menopause offer modest help at most. Soy isoflavones may slightly reduce hot flashes for some women, while black cohosh studies are inconsistent and rare liver problems have been reported. Calcium and vitamin D help protect bones after menopause. Hormone therapy and some non-hormonal prescription medicines are far more effective for hot flashes.
