Pregnant women have 10 micrograms of vitamin D per day, while about 3 micrograms daily via the diet. Vitamin D is needed to properly take calcium from food. Calcium provides the building and maintaining a strong skeleton.
The need for folate is increased during pregnancy. Research has shown that a deficiency of folic acid in the first weeks of pregnancy (when the pregnancy is often not yet been determined) the risk of spina bifida (spina bifida) in babies increases.

A slice of liver pate contains 350 micrograms of vitamin A.

The Food Consumption Survey 1998 shows that the average intake during pregnancy 829 micrograms of vitamin A per day. Also, a deficiency may be harmful: Vitamin A is essential for the proper development of the fetus. It is important not to be careful with the intake of vitamin A.
