Wherever growth and development take place, including during pregnancy, the need for vitamins increases accordingly. This is especially true for the B-group vitamins. Which vitamins are particularly important in pregnancy can be found here.
Folic acid in pregnancy
A special position among the vitamins is the folic acid. Even with non-pregnant young women, there is a critical supply situation. In the case of pregnancy, the need for folic acid increases twice, which is why only 10 percent of pregnant women can meet the additional needs of food intake.
Since a deficiency of this vitamin can promote the development of many severe malformations (neural tube defect = open back, as well as in the area of the skull of the unborn child), a substitution is indicated.
However, this must be done before a planned pregnancy. At the time of pregnancy, the embryo is already several weeks old. The sensitive phase of neural tube formation is already well advanced, which is why folic acid administration at this stage of development has little effect.
Vitamin requirement in pregnancy
|vitamins||Percentage additional need during pregnancy||Recommended total intake|
|folic acid||100%||0.8 mg|
|Vitamin D||100%||10 μg|
|Vitamin B6||63%||2.6 mg|
|Vitamin A||38%||1.1 mg|
|vitamin C||33%||100 mg|
|Vitamin B1||25%||1.5 mg|
|Vitamin B2||20%||1.8 mg|
|Vitamin E||17%||14 mg|
|Vitamin B12||17%||3.5 μg|
In principle, in the context of pregnancy, the preventive intake of iron, magnesium and folic acid is appropriate. The substitution of calcium, iodine, vitamin D and vitamins of the B group is recommended, but should take place in a controlled manner.
