Vitamin D is a fat-soluble vitamin, that is, it is soluble in fats. It generally comes in 2 forms: vitamin D2 or ergocalciferol and vitamin D3 or cholecalciferol (the most assimilable form).
Vitamin D3 contributes to the maintenance of healthy bones and muscles, as well as to the maintenance of the proper functioning of the immune system.
This food supplement helps the body absorb calcium, one of the main substances needed for strong bones. Along with calcium, vitamin D helps prevent osteoporosis, a disease that causes bones to become thinner and weaker and more prone to fractures.
