This Iranian study aimed to evaluate the effect of vitamin D supplementation on metabolic characteristics and inflammation levels (CRPs) in gestational diabetes patients. 76 pregnant women with gestational diabetes were assigned to receive either four oral treatments consisting of 50,000 IU (1250 µg) of vitamin D3 (38 women) or a placebo (38 women) once every 2 weeks for 2 months. The scientists measured fasting glucose levels, long-term glucose levels (HbA1c), inflammation, and vitamin D3 levels before and after treatment. Women in the vitamin D group had significantly increased vitamin D3 levels and significantly decreased fasting glucose and long-term glucose levels compared with women in the placebo group. More details can be found in the study.
