The Significance of Vitamin D Storage in Adipose Tissue
- Registration Number
- NCT01728987
- Lead Sponsor
- University of Tromso
- Brief Summary
- The study will examine the role of adipose tissue in vitamin D physiology, particularly its role as a depot. the study is randomized double blind and placebo controlled. 
- Detailed Description
- vitamin d versus placebo will be given for 12 months. Biopsies will be taken at baseline and every 6 month for 2 years. Blood samples will be collected every 6th month. the study will thus give information on storage during vitamin d supplementation as well as use of vitamin d fat stores after stopping vitamin D supplementation
