Brief Summary of Protocol:
Low levels of Vitamin D (also known as vitamin D deficiency) is a common condition and is found in about 30% of the population. A vitamin D deficiency can occur when usual dietary intake is lower than recommended levels over time, or exposure to sunlight is limited. Low levels of vitamin D in the blood are associated with heart disease risk factors, including harmful cholesterol levels. A recent study at Rockefeller University showed that when people took oral vitamin D, it failed to improve their cholesterol level. This may be due to the route of Vitamin D administration.

For this study, we will compare the effect of oral vitamin D repletion to ultraviolet (UV) light exposure on blood cholesterol.



Detailed Description of Protocol:
If you join the research study, you will take part for about 6 months. The research study as a whole will last about 5 years. About 120 people will take part in the research study.

The study involves:
- A screening visit
- Taking oral Vitamin D or receiving ultraviolet light treatment
- Up to 20 study visits at our Outpatient Research Center
- Blood draws
- Skin biopsies (optional)



What specifically makes a person eligible for the study?
You may be eligible to enter this study:

- Have low Vitamin D
- Are generally healthy
- Are not taking Vitamin D or Cholesterol medication

Gender:
Both

Age(s):
18-70

Children permitted to participate:
No

Potential Benefits.....
The benefits you might expect from taking part in this research study are:
- You may benefit if your vitamin D level return to normal.
- You may find out during the research study that the vitamin D or UVB light therapy is helpful to you.
- You may benefit from what we learn in this research study whether vitamin D and/or UVB light therapy helps you or not.



Compensation:
Compensation is provided.
