Summary
Multiple sclerosis, a chronic disease affecting the central nervous system, is characterized by impaired immune function and an imbalance of immune cells, which are involved in developing this disease. Vitamin A can correct this imbalance. This Iranian publication reports on the results of a clinical trial with 36 MS patients who received vitamin A (25000 IU = 3000 µg) or a placebo daily for 6 months. Immune cells were isolated from patients, and the expression of specific factors involved in immunological processes was measured at the beginning and end of the study. Vitamin A was found to have beneficial effects on these factors. Therefore, the researchers suggested that vitamin A supplementation could be considered a new MS prevention and treatment approach. More details can be found in the study.
