Risk factors[edit]
RA is a systemic (whole body) autoimmune disease. Some genetic and environmental factors affect the risk for RA.

Vitamin D Deficiency
There are claims that patients that have lower vitamin D levels by 8-10 ng/mL are at risk for rheumatoid arthritis.

Prevention[edit]
There is no known prevention for the condition other than the reduction of risk factors.

Supplementation
Evidence suggests that increasing vitamin D levels to the range of  40–60 ng/mL could reduce the risk of rheumatoid arthritis.
