When is the best time to eat folic acid? When is the best time to eat folic acid

It should be eaten after meals. The daily dosage should be strictly controlled, and high-dose "folic acid tablets" (each tablet contains 5 mg of folic acid) should not be used to avoid adverse effects on pregnant women and fetuses.

The main effects of folic acid tablets:

1. Prevention of fetal neural tube malformations (anencephaly, spina bifida), up to 85.

2. Prevention of fetal cleft lip and palate, with a rate of 50.

3. Prevent birth defects such as fetal congenital heart disease and other body surface malformations.

4. Prevent anemia in pregnant women, lactating mothers and fetuses.

5. Promote the development of fetal nervous system.

6. Reduce infant mortality.

7. Reduce pregnancy reactions.

Other functions] 1. It can prevent chronic cardiovascular diseases such as coronary heart disease.

2. It can prevent Alzheimer's disease and other cancers and reduce the incidence.

3. Reduce and prevent the incidence of breast cancer and cervical cancer in women.

4. Prevention and drug-induced megaloblastic anemia.

What is the difference between milligram low-dose folic acid tablets and 5mg folic acid tablets?

Milligram low-dose folic acid tablets are clearly defined as "preventive drugs" in the dosage of the 2000 edition of the pharmacopoeia, and are mainly used for prevention.

initial and recurrent neural tube defects; Moreover, it can prevent anemia in pregnant women, severe pregnancy reactions, spontaneous abortion and promote it.

The normal development of the fetal central nervous system and the prevention of intrauterine growth retardation of the fetus.

5 mg folic acid tablets, which is the "first drug", is mainly used for megaloblastic anemia caused by vitamin B12 deficiency.

5 mg folic acid tablets should not be used as a substitute for small dose folic acid tablets.

How long does it take to take milligram folic acid tablets?

Folic acid supplementation is most effective in preventing neural tube defects in women from one month before pregnancy to the end of the third trimester after pregnancy, when the pregnancy is in the womb.

The period of development of the central nervous system in children. Due to the fact that the level of folic acid in the body of women of childbearing age in China is generally low, and the body of women after pregnancy.

Folic acid levels will gradually decrease as pregnancy increases, so women start taking it when they are married or planning to become pregnant until after pregnancy.

The end of the third month is more appropriate, and it is also beneficial for the woman to start taking it earlier and for a longer period of time. The multiparous woman conceived again.

During pregnancy, it should also be taken from 1-3 months before pregnancy to prevent the occurrence of neural tube defects, and pregnant women with conditions can be used throughout pregnancy.

During the period of lactation and lactation, it is necessary to take it consistently to facilitate the health of the mother, the growth and development of the fetus and newborn.

Studies have shown that folic acid supplementation after pregnancy is known to be clear will not help prevent the development of neural tube defects in fetuses and neonates. Folic acid (folic

ACID) as a coenzyme of one-carbon unit (mainly methyl)transferase, participates in the metabolism of amino acids and nucleotides in the body, and is an indispensable nutrient for cell proliferation, tissue growth and body development. Animal experiments and population epidemiological studies have shown that folate deficiency or use of folate antagonists (eg, abortifacients, antiepileptic drugs) in the first trimester of pregnancy can cause stillbirth, miscarriage, fetal brain and neural tube defects. Human folic acid intervention trials have confirmed that folic acid supplementation in the first trimester, i.e., during embryonic neural tube differentiation, can effectively reduce the occurrence of fetal neural tube defects.

Another study, which supplemented mothers who had had had babies with neural tube defects with milligram-days of folic acid, showed that the supplementation reduced the birth rate of babies with neural tube defects by 70% in the next pregnancy.

However, a considerable number of pregnant women do not go to folic acid supplementation until they know they are pregnant, which loses its preventive effect. Because the neural tube differentiation of embryos mostly occurs 2 to 4 weeks after fertilization, that is, 4 to 6 weeks of gestation, most women do not know that they are pregnant, and often ignore folic acid supplementation. According to studies, it takes 4 weeks for a woman to take folic acid before the state of folic acid deficiency in the body can be corrected.

Therefore, women should start taking folic acid from one month before pregnancy to maintain a certain level of folic acid in the body to ensure that the embryo has a better nutritional status of folic acid in the early stage. In this way, during the sensitive period of fetal neural tube formation in early pregnancy, there can be enough folic acid to meet the needs of nervous system development, and it should be taken consistently during the sensitive period of the first three months of pregnancy to have the best preventive effect.

When to take folic acid when pregnant?

Generally speaking, for female friends who are preparing for pregnancy, they should start taking folic acid tablets three months before they are trying to get pregnant, because after taking folic acid tablets before pregnancy, they can regulate the physique of pregnant mothers. Especially in the first trimester of pregnancy, an appropriate amount of folic acid supplementation is also needed, which can promote the development of the fetal nervous system and has a significant effect on preventing miscarriage and malformation. Folic acid tablets are more effective when taken half an hour before or after dinner or before breakfast.

Because the stomach is emptying at this time, taking it half an hour before meals is the best time for folic acid to be absorbed. In addition to taking folic acid during pregnancy, it is also necessary to take a moderate amount of foods and fruits with high vitamin content, and secondly, foods containing folic acid should also be eaten. For example, leeks, carrots, beef, etc. are rich in folic acid.

When is the best time to take folic acid? It is recommended to take an appropriate amount of folic acid in the first trimester and first trimester during pregnancy, which can prevent premature birth, miscarriage and malformations during fetal development. Secondly, it has a very good effect on preventing fetal malformations and promoting the development of the nervous system.
