Folic acid is necessary for a person for normal hematopoiesis, cell division, assimilation of sugar and amino acids, the formation of nucleic acids (RNA and DNA) involved in the transmission of hereditary traits, and so on.
To get this vitamin from nature, you need to consume greens and vegetables with a dark green tops. But it is very important to eat them raw, as during the heat treatment 90% of the vitamin is destroyed. In addition, rich in folic acid and products such as yeast, liver, egg yolk, cheese, melon, apricots, pumpkin, avocado, beans, whole wheat and dark rye flour. In a day a person needs 400 micrograms of "foliage", and during pregnancy this need is doubled. Taking folic acid preparations when planning a pregnancy, it is necessary to strictly follow the doctor's recommendations or follow the instructions.
There are a number of folic acid preparations on the pharmaceutical market, one of which we'll talk about.
One Folacin tablet contains 5 mg (5000 ?g) of folic acid. This dose of the drug exceeds the body's need (400 mcg) many times (provided that the body does not experience deficiency of this vitamin). Since this drug contains not a preventive but a therapeutic dose of folic acid, its purpose should be based on a pronounced vitamin B9 deficiency. During pregnancy planning, when it is necessary to replenish the stores of vitamins and prepare a healthy "soil" for the development of a new life, a woman is prescribed 1 tablet a day. This is quite convenient, since a smaller number of receptions (not 3-4, as is usually prescribed when using drugs with a lower content of folic acid) excludes the possibility that a woman will forget about another appointment.
Why is it important to take folacin even at the planning stage? Yes, because, in the case of pregnancy, a lack of folic acid can affect the formation of the neural tube in the embryo and cause its defects. This occurs on the sixteenth, twenty-eighth day after conception. This will not happen if before the pregnancy the woman took care of replenishment of folic acid stores. Besides, if a woman took oral contraceptive, the doctor will also prescribe folacin or its analogues.
Are there any side effects from the drug? The instructions say that allergic reactions (skin rashes, itching, erythema, bronchospasm) are possible, reactions from the gastrointestinal tract in the form of anorexia, nausea, bloating, bitterness in the mouth are also possible.
The maximum concentration of the drug in the blood is observed 30-60 minutes after admission. In case of an overdose, the excess of the substance is removed from the body. But this does not mean that you can drink it in tons, because there's no use in it.
