Is this trial a fit for you?
✓Likely a good fit
Ideal candidates are healthy non-Hispanic Black or non-Hispanic White adults aged 18-75 with normal blood pressure and cholesterol levels.
✕Probably not a fit
Patients with existing cardiovascular or metabolic diseases, skin disorders, or those on certain medications may not benefit from this study.

What this trial studies
This study investigates the impact of an antioxidant supplement on vascular function in healthy non-Hispanic Black adults, who are at higher risk for cardiovascular disease. It aims to determine if oxidative stress from mitochondria contributes to vascular dysfunction, potentially leading to hypertension and cardiovascular issues. Participants will receive either the antioxidant supplement MitoQ, MitoTempo, Tempol, or a placebo to assess changes in blood vessel health. The study focuses on understanding the role of oxidative stress in maintaining cardiovascular health.
Why it matters
Potential benefit: If successful, this study could lead to new preventative strategies for cardiovascular disease in at-risk populations.
How similar studies have gone: While there have been studies on antioxidants and vascular health, this specific focus on the non-Hispanic Black population and mitochondrial oxidative stress is relatively novel.
