The Effect Of Vitamin D On Measures Of Bone Health And Gene Expression
Completed
Conditions studied: Vitamin D Deficiency
In brief
Vitamin D deficiency is now recognized as one of the most common vitamin deficiencies in adults in the United States. Vitamin D deficiency has been connected to many chronic health diseases. The goal of this innovative research is to identify how vitamin D is able to have such wide ranging health benefits. This study will determine which genes are turned on and turned off in adults who receive 2000 IU vitamin D3 per day compared to 400 IU vitamin D3 per day. Results should provide important new insights about the health benefits of vitamin D for adults.
