A paper published in the European Journal of Clinical Investigation showed that vitamin D levels may help lower lupus disease activity.

Conducted at Ajou University in Korea, the study evaluated lupus disease activity levels among participants during winter and summer.  They found that in both seasons, the percentage of people who had low lupus disease activity was highest among those who had sufficient levels of vitamin D and lowest among those who were deficient in vitamin D.

Investigators concluded that “physicians should pay attention to the adequacy of vitamin D levels and consider recommending vitamin D supplementation for patients with vitamin D insufficiency.”
