Vitamin D
Vitamin D is very beneficial for the body but also plays an important role in protecting the body’s immune system. When a person is deficient with vitamin D, then his or her chances of developing multiple sclerosis also increases substantially. As we know that the biggest source of vitamin D is sunlight, so that people who have less exposure to sun and outdoors are more likely to develop vitamin D deficiency, which ultimately leads to the development of multiple sclerosis.
