There is more research coming out that shows the connection that vitamin D has to our immune system. Specifically, vitamin D deficiency seems to be more prevalent in those with autoimmune disorders like rheumatoid arthritis (RA).
A new study compared those with RA to a control group to see if there would be a difference in vitamin D status. They found that the RA group had significantly lower levels of vitamin D, further confirmation that vitamin D plays a role in RA and possibly other autoimmune disorders.
