Vitamin D Supplementation on Adolescent Girls

Clinical Study Title:
The effect of conventional vitamin D(2) supplementation on serum 25(OH)D concentration is weak among peripubertal Finnish girls: a 3-y prospective study.

Plain English Summary:

This study looked at the use of a vitamin D supplementation during non summer months on the vitamin D levels in the body of adolescent girls. The participants were interviewed and labs were done to determine intake levels and levels in the blood. During the summer months, there were no instances of a deficiency of vitamin D. During the nonsummer months however, there were several cases of deficiencies. A vitamin D supplement was able to correct this. This suggests that a daily supplement to vitamin D should be considered for all adolescent girls, but especially during the winter to compensate for the lack of sunlight.
