This study, conducted by research centers and universities from Germany, Switzerland, and the USA, investigated the associations between vitamin D deficiency and multiple sclerosis (MS). In MS, the body mistakenly attacks the protective layer around the nerves in the brain and spinal cord. These damaged areas are called lesions. 53 MS patients were involved in the study. Vitamin D levels were evaluated at the start of the study, and patients were split into different groups based on their vitamin D levels. The results showed that higher vitamin D levels were significantly associated with fewer lesions and improved disability status. You can find more details in the study.
