MitoQ supplement may boost brain artery health in postmenopausal women

This study tests whether taking MitoQ, a dietary supplement, for 3 months can improve blood flow in the brain's arteries in healthy women aged 60 and older who have gone through menopause. Participants will take either MitoQ or a placebo daily and have their brain artery function measured at the start, halfway, and end of the study. The goal is to see if MitoQ can reverse age- and menopause-related declines in cerebrovascular health.
