Effects of an Antioxidant Supplement on Blood Vessel Health

Description

Cardiovascular disease (CVD) is a leading cause of morbidity and mortality worldwide, and the non-Hispanic Black (NHB) population is disproportionately affected. Our research has previously demonstrated that oxidative stress may contribute to reduced vascular function in otherwise healthy NHB adults, potentially predisposing them to the development of hypertension and CVD. This study is designed to examine whether the mitochondria are an important source of oxidative stress-induced vascular dysfunction in healthy NHB adults.
