Vitamin D comes in several forms:

  1. Vitamin D2 ( ergocalciferol ) is found in plant foods such as mushrooms, avocado or soy.

  2. Vitamin D3 ( cholecalciferol ) is produced by skin exposed to the sun. It is also found in foods of animal origin such as fatty fish, egg yolk or certain dairy products.

We know what you are wondering: “ how can a vitamin appear thanks to the ultraviolet rays of the sun?

The sun's UV-B rays allow the skin to naturally synthesize vitamin D. Under the action of UV-B radiation, the cells of the epidermis are able to synthesize vitamin D3 from cholesterol. Fat-soluble, vitamin D is thus stored in the body.

In regions where the climate is cold and not very sunny, vitamin D reserves in the body decrease over the winter. The level of vitamin D in the body therefore becomes deficient, which can cause muscle discomfort. Stocking up on vitamin D in winter is essential for overall well-being. Follow us, we explain everything about the benefits of vitamin D on the body!
