The investigators obtain vitamin D through our diet and sunlight, and its conversion to active vitamins in the liver and kidneys promotes the intestinal absorption of calcium and regulation of bone growth. Therefore, vitamin D deficiency has been known for years to lead to weakened bones (osteopenia and osteoporosis). However, more recently, studies show vitamin D deficiency is associated with a number of other diseases, including type 2 diabetes, muscle weakness, frailty, and the metabolic syndrome. It has also been associated with cognitive impairment. Diabetes affects multiple organ systems including the heart, kidneys, musculoskeletal and nervous system. The possibility that vitamin D deficiency is linked to the development of type 2 diabetes, metabolic syndrome, muscle weakness and wasting (sarcopenia) and osteopenia/osteoporosis, and that vitamin D supplementation decreases the risk for these diseases, provides a relatively easy/accessible and inexpensive model of preventive therapy to decrease the incidence of these diseases. In addition, it is likely that genetic (inherited) factors play a role, but the relationship of these genes to these metabolic abnormalities have not been elucidated. Understanding the role of Vitamin D in health will allow us to translate these findings into therapy.'}, 'eligibilityModule': {'sex': 'ALL', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'maximumAge': '85 Years', 'minimumAge': '40 Years', 'healthyVolunteers': True, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* 40-85 years of age\n* Women must be post menopausal (absence of menses for 12 months or greater)\n* 25-hydroxyvitamin D level below 20 ng/ml (50 nmol/L)\n* BMI 25-45 kg/m2\n* Non smoker ( non smoking for at least 12 months:cigarettes, cigars, pipes)\n\nExclusion Criteria:\n\n* Symptomatic heart disease, CAD, CHF, or uncontrolled hypertension (BP over 180 mm HG) unless medically stabilized\n* Currently being treated for active cancer\n* Type 1 diabetes;
