This trial, executed by three Indian research departments, aimed to assess the effects of vitamin D and calcium on metabolic factors and oxidative stress levels in women with gestational diabetes. The trial was conducted on 70 women diagnosed with gestational diabetes who received either 1000 IU (25 µg) of vitamin D and 1000 mg of calcium (group A: 34 women) or 250 IU (6,25 µg) of vitamin D and 500 mg of calcium (group B: 36 women) daily for 6 weeks. Vitamin D levels, fasting glucose (sugar) levels, insulin levels, and fasting lipid levels were analyzed before and after supplementation. The researchers found that group A had significantly lower fasting glucose levels, fasting insulin levels, and total cholesterol levels in their blood. Group B had a significant decrease in fasting glucose level after 6 weeks of supplementation. These results indicate that vitamin D and calcium at a dose of 1000 IU (25 µg) and 1000 mg, respectively, have a beneficial effect on glucose metabolism, lipid metabolism, and oxidative stress levels in gestational diabetes. More details can be found in the study.
