Vitamin D is one of the oldest compounds on earth.
Initially it was classified as a vitamin. Now we know it’s more than just a vitamin it’s a pre-hormone.
Plants create Vitamin D2 under ultraviolet light. Animals and humans create Vitamin D3 also known as Cholecalciferol.
When our skin is exposed to ultraviolet radiation B it produces Vitamin D3 from the body’s cholesterol. After that it’s delivered to the liver and that turns it to the active form. This is the form used by the body.
Initially it was believed that Vitamin D is only making our bones strong. As science advanced more links were found.
For example it helps regulate the mood. Someone with Vitamin D deficiency will be more likely to suffer from depression.
If somebody has a weak immune system it means that the D3 levels are low in their blood.
Vitamin D has been shown that it can control insulin release and insulin sensitivity. Besides all these if somebody suffers from bone pain (including the back) it might be the lack of this vitamin.
Many who suffer from hair loss are deficient in Vitamin D. To combat this many creams and lotions add D3 to their ingredients list.
As you can see Vitamin D plays a huge role in the body’s processes. You won’t probably notice it until you end up deficient in it.
For more information on this please check out this article. I go deeper and explain more uses of this vitamin / pre-hormone.
Scientists have shown that our cells have Vitamin D receptors. So we can expect the number of functions on which D3 has an effect on will increase in the future.
