Vitamin D’s importance is well established, playing a vital role in bone and dental health. Your body requires a sufficient amount of Vitamin D, in order to absorb calcium efficiently and to prevent the occurrence of high serum parathyroid hormone concentration, which stimulates the transportation of calcium from the bones, thus diminishing bone mass and preventing the development of healthy, strong, new bone. Although vitamin D is required for optimal bone formation, it is much more effective when calcium intake is adequate.

Vitamin D3, as previously stated is the form of vitamin D produced by the skin. D2 (Ergocalciferol), is produced by fungi and is used in many supplements and to fortify foods. After formation of vitamin D by the body, it is stored as one of two different metabolites; 25-hydroxyvitamin D (calcidiol) and 1, 25-dihydroxyvitamin D (calcitriol). The body’s main storage of vitamin D, calcidiol is activated to make calcitriol when needed by the body, thus requiring a healthy liver and kidneys are essential for optimal vitamin D serum levels.*
