Can FADS1 help with Wechseljahre?

Whether FADS1 can help with menopause symptoms is not well established. FADS1 encodes delta-5 desaturase, a key enzyme in the conversion of omega-3 and omega-6 fatty acids. Genetic variants in FADS1 can alter the efficiency of producing long-chain polyunsaturated fatty acids like EPA and DHA from plant-based precursors. Since omega-3s have anti-inflammatory properties and may influence hormone regulation, a mechanistic link to menopausal issues such as hot flashes and mood changes is plausible. However, direct clinical evidence linking FADS1 genotyping to menopause relief is lacking. The evidence is therefore mechanistic at best. A diet rich in omega-3s (fatty fish, flaxseed) or supplementation under medical guidance may be beneficial for general health during menopause, but this advice does not depend on FADS1 status. Caveat: genetic testing for FADS1 is not clinically validated for menopause management; lifestyle and hormone therapy have stronger evidence.
