One of the best-known roles of vitamin D (calciferol) is its function in calcium and phosphorus absorption. These two minerals are essential for bone growth, so it naturally follows that vitamin D is key to skeletal health.
However, vitamin D is also necessary for proper hormone function. In this role, it helps regulate immune response, insulin secretion, and blood calcium levels.
Two other important functions of vitamin D are carbohydrate metabolism and gene expression, which translates into embryonic growth.
