Vitamin D

Usage of Vitamin D

Vitamin D has to be one of science’s most misunderstood vitamins.

For a start, it is not actually a vitamin, but a prohormone, which means that it is converted into a hormone by our body. It is also not just one substance, but five different substances, of which two have been identified as being the most important to humans. These are:

  • Vitamin D2 (ergoCalciferol)
  • Vitamin D3 (cholecalciferol).

    • In addition, research has discovered that vitamin D is not only vital for calcium absorption and bone growth and remodeling, but several other important processes as well, such as modulating cell growth and immune system function.

    Vitamin D acts on our bones, intestines, kidneys and parathyroid glands to keep calcium in balance throughout our body. Vitamin D receptors are also located within our cardiovascular system, lungs, pancreas, skeletal muscle, skin, and reproductive organs. In summary, vitamin D is a prohormone that is essential for good health.

    Only 10% of the vitamin D our body needs is obtained from food. The rest is made by our bodies when our skin is exposed to sunlight.
