Vitamin D exists naturally in two forms: vitamin D2 (ergocalciferol) of vegetable origin and vitamin D3 (cholecalciferol) of animal origin.
D3 Biane in drop allows to supplement the food contributions in vitamin D: a drop contains 100% of the recommended daily contributions in vitamin D3.
Acting in a large number of metabolisms, vitamin D acts on bone density by promoting the assimilation of calcium. It also plays a role on our immune defenses. Its contributions must be optimized for certain categories of population. In fact 80% of the population is deficient in vitamin D.
Vitamin D has the distinction of being both provided by our diet (for a third) and synthesized by our body by the exposure of our skin to the sun’s rays (for two thirds). This specificity explains the frequent deficits in vitamin D during the winter or for people exposed little to the sun.
