Which vitamin is said to be helpful in reducing the risk of diabetes?

Vitamin D has been extensively studied for its role in insulin sensitivity and glucose metabolism. Research suggests that adequate Vitamin D levels may improve pancreatic beta-cell function and reduce insulin resistance, thereby potentially lowering the risk of developing type 2 diabetes. While Vitamins A, B, and C are essential for various bodily functions, they are not specifically linked to diabetes risk reduction in the same way as Vitamin D.
