Summary
This Iranian study aimed to assess the safety and efficacy of high-dose oral vitamin D3 in pregnant women with multiple sclerosis (MS). To this end, 15 pregnant women with MS and low vitamin D levels received either 50000 IU (1250 µg) of vitamin D3 per week or only routine care from the 12th to 16th week of gestation until delivery. In conclusion, this study showed that high-dose vitamin D3 supplementation during pregnancy positively affected the vitamin D levels, disability status, and the number of relapse events in pregnant women with MS. You can find more details in the study.
