All About Vitamin D3

What is Vitamin D3

Vitamin D3 is not technically a vitamin. It is a fat-soluble pro-hormone which is vital because it influences your entire body. Receptors that respond to the vitamin D3 have been found in almost every type of human cells, from your brain to your bones.
As a study by the Toronto group revealed, Vitamin D deficiency is present in 22% of individuals of European ancestry, 78% of East Asian ancestry and 77% of South Asian ancestry. 5 Possible ethnic differences in physiological pathways for ingested vitamin D may confound across the board recommendations for vitamin D levels. Even a suggested 5000 IU/day by more conservative experts seems to mark an existing recommended daily allowance of 400 IU per day as “Just Enough Not To Die”.

How Do We Get Vitamin D3?

Vitamin D is commonly obtained either from the skin when it is exposed to ultraviolet radiation or through a few dietary sources ( mainly fatty fish, cod-liver oil, and fortified margarine or butter). Experts recommend taking vitamin D3 supplements on a regular basis because food sources are extremely limited as well as our natural production. It is noteworthy that a precursor of vitamin D3 in skin can be generated only when exposure to the sun happens when the sun is at the highest point. This fact has never been explicit in official recommendations because of a general concern about a risk of skin cancer development. In humans, the precursor to this hormon is produced in the skin when cholesterol (7-dehydrocholesterol) is exposed to sunlight (UV B radiation). Next, this precursor is carried further to your liver (to become 25-hydroxyvitamin D) and then to your kidneys where it gets transformed into active vitamin D3 (or 1,25 dihydroxyvitamin D).

Importance of Vitamin D3

Forms of Vitamin D

Vitamin D3 (or Cholecalciferol) is one of two forms of Vitamin D. Another form is Vitamin D2 (or Ergocalciferol). It is important to stress that 90% of all Vitamin D circulating in our body is Vitamin D3 because it is made by the skin after exposure to sunlight. Vitamin D2 can only be acquired from a few plant sources (e.g mushrooms).Vitamin D deficiency is quite a common problem, which only increases as we age.
