Vitamin D3, or cholecalciferol, is the most bioavailable form of vitamin D.

It is usually extracted from fish, with cod and sardine oils, butter and egg yolk being good sources of vitamin D. Vegetables are low in vitamin D, with green leafy vegetables being the richest.
Vitamin D can also be produced through the action of Ultra-violet rays on the lanolin present in sheep's wool. Usually vitamin D3 supplements also contain vitamin A in their composition, and thus, in cases of need for vitamin A restriction, such as during pregnancy, vitamin D intake will be affected accordingly.

The knowledge that we must protect ourselves from sunburn and the effects of ultraviolet rays on our skin, resulted in a greater use of sunscreens, hats and clothing in order to protect ourselves from the sun, which came in turn , reduce the production of vitamin D by the skin. Deficit of this vitamin has become more common in general, with the elderly standing out because they are usually less exposed to sunlight.

Vitamin D is unique among essential nutrients, since it is a vitamin that has the ability to transform into a hormone. Once ingested, and already in the liver, vitamin D becomes a metabolite called 25-hydroxycholecalciferol [25-OH-D3], which in turn will be converted into its active form in the kidneys, in 1,25 dihydroxicolecalciferol [1,25 , 2- (OH) 3-DXNUMX].
It is in this active form that Vitamin D acts as a hormone, 10 times more potent than its precursor, and like other hormones, it functions as a chemical messenger responsible for the regulation of certain body functions.

Traditionally vitamin D is associated with calcium balance and bone health.

Since it is produced in the kidneys, the active form of Vitamin D works in different processes:
Mobilization of calcium and phosphorus into bone tissue is vital for absorption of calcium and phosphorus ingested through food and calcium reabsorption in the kidneys, acting on the thyroid and parathyroid, also playing a role in nervous and immune function.

There are several recent studies that highlight the importance of this vitamin, not only due to the role it plays in bone tissue, but also in terms of mental health and immunity. Vitamin D intake is associated with a lower rate of cancer risk, prevention of colds and flu, and a lower risk of depression and better mental acuity in the elderly.
Its ability to model cell proliferation and differentiation in the pancreas, colon and breast tissue has already been demonstrated.
