The question of whether AMH (anti-Müllerian hormone) can help with longevity is not supported by strong evidence. AMH is a well-established marker of ovarian reserve used in fertility medicine. Some observational studies suggest that higher AMH levels are associated with later menopause, which in turn is linked to lower all-cause mortality and potentially longer lifespan. However, this is an indirect association, not a proven causal mechanism. There are no clinical trials demonstrating that increasing AMH levels (e.g., via supplements) extends lifespan. Direct-to-consumer tests that market AMH as a 'longevity biomarker' overstate its predictive value. AMH is not a validated longevity marker; factors like caloric restriction, exercise, and genetic background have far stronger evidence. Caveat: AMH naturally declines with age; interventions to raise it are not recommended. Evidence: unclear/mechanistic.
