Vitamin D deficiency is associated with the incidence and prevalence of various neurologic disorders, including multiple sclerosis. This Turkish study aimed to assess the relationship of vitamin D deficiency with health-related quality of life and fatigue in MS patients. Therefore, vitamin D3 levels were measured in 149 MS patients. Patients with a vitamin D deficiency were administered a vitamin D supplement. The results showed that 90% of the patients were vitamin D deficient. After vitamin D supplementation, health-related quality of life and fatigue improved significantly. Additionally, there was a direct association between the quality of life and the absence of fatigue and vitamin D levels at the end of the study. The researchers suggest that vitamin D supplementation should be considered a potential therapy in MS patients. More details can be found in the study.
