During pregnancy you can take a multivitamin, which is a supplement of micronutrients and also folic acid. Folic acid is good for preventing neural tube malformations, so it is recommended to take a multivitamin during the preparation for pregnancy, and also during the first 3 months of pregnancy. Each multivitamin contains 0.8mg of folic acid, the amount of folic acid that prevents neural tube malformations in babies. Folic acid is also involved in the formation of hemoglobin, and taking a multivitamin is useful in preventing anemia. Most pregnant women can eat up to 3 months, but there are pregnant women who do folic acid metabolism suggesting folic acid deficiency, in which case the multivitamin can be taken for a few more months.
