Vitamin D deficiency is highly prevalent among women with gestational diabetes. This study, executed by Iranian researchers, aimed to assess the effect of vitamin D supplementation on this diabetes type. The trial was performed with 45 pregnant women diagnosed with gestational diabetes who did not take anti-diabetes medication. The participants were randomly assigned to consume either 50000 IU (1250 µg) of vitamin D (22 participants) or a placebo (23 participants). Blood samples were taken at the start of the study. Additionally, glucose tests and blood tests were performed. The study showed that taking vitamin D supplements for 6 weeks significantly improved pregnancy results compared with the placebo group. More details can be found in the study.
