Vitamin D Binding Protein (Gc) Allele Variation Effects Response to Vitamin D Treatment

Completed

Conditions studied: Vitamin D Status

In brief

We have just completed a randomized, clinical trial of 100,000 IU Vitamin D3 given as a single dose at the beginning of winter. We found a wide range of responses to the dose. This study proposes that genetic differences account for some of the variation in response of 25(OH)D levels after treatment with oral Vitamin D.
