Normally in humans vitamin D is created in the epidermal layer of the skin. Skin exposed to ultra violet radiation reacts with 7-dehydrocholesterol to produce vitamin D3 (cholecalciferol). The vitamin D3 is then absorbed into the blood stream and metabolized by the body. So then how do animals that have fur or feathers covering their skin receive the necessary vitamin D?
The process of converting 7-dehydrocholesterol to vitamin D3 is the same. What is different is how it enters the animals’ blood stream. Animals produce the vitamin D3 on their fur and then lick the vitamin D3 from their fur and ingest it orally. Although the chemical is the same as require by humans, we are not suggesting you pick-up you cat and start licking it. We’re suggesting, if you’re Vitamin D deficient, start taking Vitamin D3 orally. You’re an animal, so start taking it like it like one.
Research shows that between 60 and 75 percent of Americans are Vitamin D deficient. This is a major health concern. Vitamin D is fundamental in the absorption of calcium, the immune system’s ability to fight pathogens and cancer prevention. Every day I read a new study connecting a disorder to Vitamin D deficiency.
