Is BDNF useful for menopause?

BDNF (Brain-Derived Neurotrophic Factor) is a protein crucial for neuronal plasticity and survival. During menopause, declining estrogen levels may influence BDNF expression, potentially contributing to cognitive changes or mood symptoms. Some observational studies show lower BDNF in menopausal women, but evidence is limited and not causal. There is no strong clinical trial data proving that boosting BDNF (via supplements, exercise, or diet) reliably alleviates menopause-specific symptoms. Lifestyle factors like aerobic exercise and a Mediterranean diet can modestly increase BDNF, but these effects are general, not menopause-specific. Direct-to-consumer genetic tests claiming to predict menopause-related BDNF decline lack robust validation. Evidence grade: human-observational/mechanistic. Caution: Do not self-supplement based on BDNF tests; consult a healthcare provider for personalized menopause management.
