This study aimed to determine the impact of vitamin A on disease progression in multiple sclerosis (MS) patients. 101 MS patients participated in this study, which lasted one year. The treatment group received a supplement containing 25000 IU (7500 µg) of vitamin A for 6 months daily, followed by 10000 IU (3000 µg) of vitamin A daily for another 6 months. Several tests and brain MRI scans were performed at the study’s beginning and end. The research group found that vitamin A supplementation significantly improved the general condition of the involved MS patients. More details can be found in the study.
