The beneficial effects of vitamin D

Why are summer and sunshine periods and factors that vitamin D?

Vitamin D has two origins:
– Vitamin D2 (ergocalciferol), produced by plants
– Vitamin D3 (cholecalciferol) of animal origin

The human organism transforms the Vitamin D2 in Vitamin D3. Vitamin D can be obtained from lanolin, which is obtained from sheep’s wool. It can also be found in plant form, from yeast exposed to ultraviolet rays.

We can synthesize vitamin D at the level of the epidermis under the action of UVB. This synthesis is mainly carried out from April to September (in France), the months when the sun is at its greatest. Theoretically, 15 to 20 minutes of sunshine in summer is enough to cover 70% of the demand.
