Role of Fat Tissue in Vitamin D Metabolism
NCT00033826 · Status: COMPLETED · Type: OBSERVATIONAL · Enrollment: 41
Last updated 2013-05-24
Summary
Vitamin D is a fat soluble vitamin that has important effects on calcium (including absorption of calcium from the diet) and bone metabolism. Vitamin D is known to be stored in fat tissue, and it is also present in the circulation. The purpose of this study is to investigate the relationship between levels of vitamin D in fat tissue and in blood.
