Most folic acid comes in tablets or capsules, so folic acid is swallowed with water and does not need to be chewed and eaten. The effect of swallowing is the same as that of chewing and will not affect the efficacy of folic acid. Folic acid is an essential nutrient during pregnancy and preparation for pregnancy, because it has a very obvious effect on promoting the development of the baby’s nervous system and preventing neural tube malformations. It is recommended to take it for three months during the preparation for pregnancy, and you need to continue taking it after you get pregnant. Around the third month of pregnancy, it is recommended to go to the hospital for a folic acid metabolism test. If folic acid metabolism is normal, there is no need for additional folic acid supplementation during pregnancy. The daily folic acid requirement can be achieved by eating vegetables and animal livers. However, if there is an obstacle in folic acid metabolism, it means that the body is still deficient in folic acid, and you need to extend the folic acid consumption time as appropriate.
