Vitamin D Dose Finding Study

Optimal vitamin D (vit D) concentration and metabolism are essential for normal immune function, growth, muscle, bone, and inflammatory status in children, adolescents and adults with HIV/AIDS. The impact of vit D supplementation will be evaluated for safety and efficacy using clinically important outcomes, and this will overcome the critical barrier for use of vit D supplementation in research and clinical care. Inexpensive and easy to administer, vit D supplementation may prove to be an effective and feasible treatment for symptoms and prevention of side effects for people of all ages living with HIV/AIDS in the US and around the world.
