Folic acid is a water-soluble B vitamin, which is mainly absorbed in the proximal jejunum. Therefore, taking folic acid before or after meals does not have a particularly great impact on its effect. At present, there is no scientific basis to prove whether folic acid is taken before meals or after meals. If it is a single folic acid tablet, the taking time depends entirely on personal preferences and habits. Take it on time every day, in the morning, at noon and at night.
If it is compound folic acid, it is suitable to be taken with meals or according to the drug instructions. Relevant pharmacological studies show that when folic acid is deficient in human body, it will inhibit epithelial proliferation of human digestive tract and cause diarrhea and other symptoms. Folic acid is contained in many common foods, so the phenomenon of folic acid deficiency in human body is rare. For individuals, due to physical differences, if the gastrointestinal function is poor and taking folic acid is easy to cause vomiting, such people can take folic acid half an hour after meals, so as not to affect the gastrointestinal function.
Folic acid has an important effect on pregnancy. At 4- 12 weeks of pregnancy, the nervous system of the embryo and fetus begins to develop. If folic acid is lacking, the development of the nervous system will be affected, which will lead to the appearance of deformed children. In the first three months of pregnancy, taking proper folic acid regularly can effectively reduce the appearance of deformed children.
About the dosage of folic acid: the daily requirement of folic acid for adults is between 180 and 200μg, and pregnant women should take it twice.
