Is FOXO3 useful for menopause?

Whether FOXO3 is useful for menopause currently lacks strong clinical evidence. FOXO3 is a transcription factor linked to longevity and oxidative stress. Genome-wide association studies (GWAS) have found variants in FOXO3 associated with age at natural menopause – carriers of certain alleles tend to experience menopause later. However, effect sizes are small, and predictive value for an individual is limited. A consumer DNA test can detect these variants, but no direct actionable advice follows. Menopause timing is polygenic and influenced by hormones, lifestyle, and environment. FOXO3 alone is not a clinically actionable biomarker. For understanding menopause timing, rely on established factors like family history, smoking, and BMI. Evidence: GWAS, but insufficient for individual guidance. No safety concerns, but caution against overhyped claims from genetic tests.
