Research Study Summary

The Effect of Oral Vitamin D vs. Narrow-Band UV-B Exposure on the Lipid Profile


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. If you join the research study, you will take part for about 6 months.

The study involves:

  • Taking oral Vitamin D or receiving ultraviolet light treatment
  • Up to 20 study visits at our Outpatient Research Center
  • Blood draws
  • Skin biopsies (optional)

Patient Inclusion Criteria:

  • Age 18-70
  • Have low Vitamin D
  • Generally healthy
  • Not taking Vitamin D

Patient Exclusion Criteria:

  • Pregnant
  • History of Melanoma
  • History of other cancers not in remission >6mo
