According to a new study supplementation of Vitamin D may improve fasting glucose levels as well as insulin resistance in healthy adults.
96 healthy adults were randomly determined to receive either a placebo or a Vitamin D3 supplement (420 IU) daily. The study lasted 1 year. Results showed increases in serum blood levels of Vitamin D at the end of the study period for participants supplementing with the Vitamin D3 compared to the placebo group. Decreases of 3.0 mg/dL in mean glucose concentrations were seen in the Vitamin D3 group while no changes were seen in the placebo group. Also insulin resistance (measured with the homeostasis model HOMA-IR) decreased significantly in the Vitamin D group and again no changes were seen in the placebo group.
Vitamin D is an essential nutrient involved in the maintenance of bone density and strength. It is best known for it’s ability to move calcium through the intestinal wall into the bloodstream. Even though the human body can manufacture Vitamin D under ideal circumstances there is strong evidence that many people may suffer from a deficiency of this nutrient making supplementation important. Cholecalciferol (D3) is a natural, highly bio- available form of Vitamin D.
