Pregnancy

Your doctor will prescribe Vitamin D during the first 6 months of pregnancy only if it is strictly necessary, due to the risk of harmful effects on the fetus (see section 3).

An overdose of Vitamin D during pregnancy should be avoided, as prolonged hypercalcemia can cause physical and mental retardation, as well as congenital eye and heart diseases in the child.
