Brief Summary
Participants in this study will be randomized to receive either oral vitamin D pills OR ultraviolet light treatment. The investigators will compare how these two methods of raising vitamin D levels will affect cholesterol levels.

Study Arms (2)
Oral Vitamin D3
ACTIVE COMPARATORParticipants will receive oral vitamin D3 50,000 units weekly for 8 weeks. If 25(OH)D levels remain \<35 ng/ml, subjects will receive additional doses of oral vitamin D.
Ultraviolet Light
ACTIVE COMPARATORSubjects will receive 16 treatments with ultraviolet light (narrow band UVB) over 8 weeks. If 25(OH)D levels remain \<35 ng/ml, subjects will receive additional doses of narrow band UVB.
Interventions
50,000 units orally, each week x8 weeks; supplemental doses of 50,000 units orally, each month thereafter as needed
16 treatments, 2-3 times weekly over 8 weeks; initial dose 45-75 seconds, whole-body exposure except face and groin, increasing by 10% as tolerated, to a maximum of 4.5 minutes
Eligibility Criteria
You may qualify if:
- Age \> 18 years
- Vitamin D 25-OH level \< 20 ng/ml
You may not qualify if:
- Serum calcium \> 10.5 mg/dl
- Serum phosphorus \> 5.5 mg/dl
- Serum parathyroid hormone (PTH) level \< 12 pg/ml
- LDL cholesterol \> 190 mg/dl
- History of recent acute infection (within 1 month)
- Glomerular filtration rate(GFR) \< 60 mL/min
- Liver Function tests indicative of liver disease (aspartate aminotransferase (AST) or alanine transferase (ALT) \> 3x ULN)
- Current use of Vitamin D \> 400 IU/day
- Current use of any statins, fibrates, niacin, or ezetimibe
- Current use of any medications affecting sensitivity to UV light
- Pregnancy (self-reported)
- Intentional UV exposure (e.g. tanning bed use) in the last 2 weeks or planned use while participating in the study
- history of malignancy not in remission (\> 6 months)
- History of malignant melanoma
- Participation in an investigational drug study within 30 days of the screening visit
- +2 more criteria
