The Influence of Mitochondrial-Derived Reactive Oxygen Species on Racial Disparities in Neurovascular Function

This study is investigating whether racial differences in how blood vessels function might be linked to a type of cellular stress called mitochondrial reactive oxygen species. Researchers want to understand the biology behind known racial disparities in blood vessel health and the risk of conditions like high blood pressure and stroke. **You may be eligible if...** - You are between 19 and 75 years old - Your blood pressure is no higher than 150/90 mmHg - Your BMI is below 35 kg/m² - You are free from diabetes, kidney disease, lung disease, and cardiovascular disease - You have not smoked or used tobacco in the past 12 months - You are physically able to exercise and give blood samples **You may NOT be eligible if...** - You have a history of heart disease, stroke, cancer, diabetes, or kidney disease - You have high or low blood pressure outside the stated range - You have a BMI of 30 or above (considered obese) - You smoke or use tobacco - You are pregnant or breastfeeding - You are allergic to MitoQ (the supplement being studied) Talk to your doctor to see if this trial is right for you.
