Summary

This study looked at whether tiny cell parts called mitochondria contribute to higher blood pressure and worse blood vessel health in Black adults. Researchers gave 31 middle-aged and older adults a supplement called MitoQ or a placebo for 8 weeks. The goal was to understand the role of mitochondria in racial health differences, not to treat or cure any disease.
