Is there any proof that vitamin D supplements can prevent MS or keep symptoms of MS from worsening?
Several high-profile studies have suggested that high levels of vitamin D lower the risk of developing multiple sclerosis (MS), but more research is needed to assess these findings. When a person has multiple sclerosis, the immune system attacks the coating that protects the nerve cells. Initial research suggests that a connection between vitamin D and MS could be tied to the positive effects vitamin D has on the immune system. The possible link between vitamin D and MS is strengthened by the association between sunlight and the risk of MS. The farther away from the equator a person lives, the higher the risk of MS — suggesting that exposure to sunlight may offer protection from MS. Whether this is related to ultraviolet radiation or because active vitamin D levels increase with sun exposure remains unclear. Until researchers clarify the possible relationship between vitamin D and MS, there isn’t enough evidence to recommend vitamin D as a way to treat or prevent MS. Still, vitamin D r
