Vitamin D Status and Immune Function
Completed
- Conditions
- Vitamin D Deficiency
- Interventions
- Other: In vivo immunity model
- Registration Number
- NCT02416895
- Lead Sponsor
- Bangor University
- Brief Summary
The purpose of this study is to examine the relationship between Vitamin D status and immunity.
- Detailed Description
Vitamin D is mainly obtained from the sun and follows a seasonal pattern, with Vitamin D levels peaking in summer and reaching a trough during winter. Vitamin D deficiency is associated with impaired immunity. However, knowledge of Vitamin D deficiency with in vivo immunity is limited. This observational study aims to investigate the relationship between Vitamin D status and the in vivo immunity.
