Vitamin D in the light of current knowledge
Vitamin D, i.e. 1,25(OH) 2D, is an essential factor, not only of homeostasis of calcium and phosphorus, but also of cell proliferation, differentiation and apoptosis, immune and hormonal regulation, as well as other body processes. Thus, its optimal presence in the body is of exceptional signifi...
