The Vitamin D Dose-Response Relationship

Vitamin D Production Depends on Ultraviolet-B Dose But Not on UV-intensity. A Randomized Controlled Trial

• Status: Completed
• Phase: N/A
• Study type: Interventional
• Enrollment: 55 (actual)
• Sponsor: Bispebjerg Hospital · Academic / Other
• Sex: All
• Age: 18 Years – 65 Years
• Healthy volunteers: Accepted

Summary

The purpose of the study is to determine the importance of the UV intensity and the UVB dose on the Vitamin D response after UVB.

Detailed description

The work is addressing vitamin D production after UVB exposure and explore the importance of UVB dose and UV intensity. Four different UVB doses and four different UV intensities are used to explore these relationships. Many assumptions have been made concerning the vitamin D production after UVB exposure but only few studies exist.
