You can take either folic acid or Aleve during pregnancy preparation, but you cannot take them at the same time, just choose one of them. Because folic acid is also contained in Aleve, if taken at the same time, it will cause folic acid poisoning. No matter which one you take, you need to take it according to the instruction or under the guidance of your doctor to avoid overdose. Folic acid and Aleve contain different nutrients. Folic acid is high in folic acid, while Aleve contains a small amount of folic acid, as well as vitamins and minerals to supplement the nutrients required by the fetus during pregnancy. Both can be taken during pregnancy preparation, and it is important to choose the right one to take according to the specific situation. Folic acid supplementation during pregnancy preparation can prevent fetal neural tube abnormalities and also replenish blood to prevent anemia during pregnancy. To enhance nutrition, you need to have regular medical checkups during the preparation period, and you should not smoke or drink alcohol to avoid affecting fetal development after pregnancy.
