Personalized Vitamin D Supplementation in European and African Americans
Vitamin D deficiency is associated with many adverse health outcomes and is more prevalent in individuals of African ancestry than in those of European ancestry. Treatment of vitamin D deficiency in both clinical and research settings has focused on the administration of a fixed dose of vitamin D. This investigator-initiated, intramurally-funded, randomized, double-blind, controlled trial of >300 post-menopausal women of European and African descent aims to validate an algorithm for personalized vitamin D dose.
