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.
"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."
