Hypovitaminosis D Clinical Trial
Official title:
A Randomized, Double-blind, Placebo-controlled Study on Oral Vitamin D Megadoses - 100 000 or 200 000 IU Vitamin D3 Every Three Months
The purpose of this study is to determine if infrequent administration of oral vitamin D megadoses is effective treatment to maintain serum 25-hydroxyvitamin D(3) above target levels of 50-75 nmol/L. The investigators hypothesize that 100 000 IU or at least 200 000 IU vitamin D3 in every three months would be effective and safe treatment to achieve the target levels.
