The importance of vitamin D in the prevention and treatment of diabetes and cardiovascular disease has gained increased attention in recent years. There is a need to determine what forms of vitamin D may be supplemented to correct vitamin D insufficiency and to elucidate possible mechanisms by which vitamin D sufficiency may decrease risk for developing diabetes. This randomized clinical trail will compare the effects of three different vitamin D supplements to correct insufficiency and will determine the effects of vitamin D repletion on the expression of the Klotho protein.
