Can BDNF help with Wechseljahre?

BDNF (Brain-Derived Neurotrophic Factor) is a protein crucial for neuronal survival and plasticity. During menopause, declining estrogen can reduce BDNF levels, potentially contributing to mood swings, sleep disturbances, and cognitive fog. However, no approved BDNF supplement exists; the molecule cannot cross the blood-brain barrier effectively. Some supplements (e.g., curcumin, omega-3s) and lifestyle factors (aerobic exercise) are claimed to boost endogenous BDNF, but evidence is mostly mechanistic or from animal studies. Human trials directly linking BDNF elevation to menopause symptom relief are lacking. Therefore, while the biological rationale is plausible, the evidence for using BDNF-targeted interventions in menopause is weak and largely speculative. A more evidence-based approach includes regular physical activity, stress management, and a balanced diet. Always consult a healthcare provider before starting any new regimen.
