A 16-Week Randomized Clinical Trial of 2000 International Units Daily Vitamin D₃Supplementation in Black Youth: 25-Hydroxyvitamin D, Adiposity, and Arterial Stiffness

Abstract

Daily 2000 IU vitamin D supplementation may be effective in optimizing vitamin D status and counteracting the progression of aortic stiffness in black youth. Plasma 25(OH)D concentrations in response to the 2000 IU/d supplementation are negatively modulated by adiposity.
