Chronic Supplementation With a Mitochondrial Antioxidant (MitoQ) Improves Vascular Function in Healthy Older Adults
This randomized, double-blind, placebo-controlled crossover trial examined the impact of 6 weeks of MitoQ (20 mg/day) supplementation on vascular function in 20 healthy older adults aged 60–79 years with baseline endothelial dysfunction. MitoQ significantly enhanced brachial artery flow-mediated dilation (FMD) by 42% relative to placebo, indicating improved endothelial function. Among
