Vitamin D Supplementation in Healthy Adolescents
Vitamin D Supplementation in Healthy Adolescents
This double blind, randomized controlled trial compares two supplemental doses of vitamin D
 in health adolescents.
Vitamin D deficiency is a common problem. Currently, data do not support a recommended
 vitamin D supplementation dose for health adolescents to maintain normal vitamin D levels.
 This double blind, randomized controlled 12 week trial compares the use of two supplemental
 doses of vitamin D in this population.
