Maintaining vitamin D status without sunlight exposure is difficult without supplementation.
This study was done to look at interrelationship between periodic vitamin D supplementation and immune function in Antarctic workers.
Two oral dose regimens of vitamin D supplementation on vitamin D status and immune function were evaluated in people in Antarctica with no UV light exposure for 6 months.
Participants were given either 2000U of vitamin D daily or 10,000 IU of vitamin D weekly for 6 months during a winter in Antarctica.
Study participants with higher serum vitamin D were less likely to shed Epstein-Barr virus in their saliva.
“This study provides a hint that vitamin D supplementation that results in higher blood vitamin D levels many suppress EBV within the body. Interesting? We think very interesting and trying to work out how EBV and vitamin D interact with each other. We need to know how risk factors for MS interact with each other.”
Nice post, it's great that you can publish this information online where the world can get access to it, I hope it raises more awareness of the importance of regular vitamin D and of course helps to get more focus on MS.
