What role does FADS1 play in menopause?

FADS1 encodes delta-5 desaturase, a key enzyme in polyunsaturated fatty acid (PUFA) metabolism, converting ALA to EPA and further to DHA. During menopause, declining estrogen alters lipid metabolism and inflammatory pathways. Some research suggests that FADS1 variants influence omega-3 levels, which could theoretically affect menopausal symptoms like hot flashes, bone density, or cardiovascular risk. However, the evidence is limited: most studies are GWAS linking FADS1 to blood lipid profiles, not directly to menopause-specific outcomes. No robust clinical trials confirm a causal role of FADS1 in menopause. Consumer DNA tests often overstate such single-gene effects. Therefore, FADS1 genotyping alone is not a reliable tool for menopause management. A comprehensive approach including hormone panels, inflammatory markers, and lifestyle assessment is more informative. The role of FADS1 in menopause remains an area of preliminary research, not clinical practice.
