Multiple sclerosis (MS) is a chronic, neurodegenerative disease of the nerves in your brain and spinal column, caused by a demyelization process. In MS, your immune system mistakenly attacks the myelin, which is a protective coating around your nerve fibers.
This leads to disruptions in the messages sent around your brain and spinal cord, leading to symptoms such as trouble balancing, muscle weakness, tremors, pain, and fatigue.
Researchers have long been searching for a method to repair this damage to the myelin, and thereby slow, stop or even reverse the course of the disease.
While your body does have the ability to repair myelin naturally, this process tends to become less effective as you get older. Now, however, researchers have uncovered a natural option that might play a major role in boosting the repair of damaged myelin in people with MS: vitamin D.
