Common brands of folic acid tablets include Silien, Thomson, Nature’s Best and so on. The efficacy of folic acid has nothing to do with the brand. Folic acid tablets can effectively prevent fetal malformations, can enhance the body resistance of pregnant women, and can also supplement vitamins. If the body has abnormal folic acid metabolism and serious deficiency of folic acid, it is easy to cause serious anemia symptoms. There are still very many brands of folic acid tablets. For women with normal pregnancy, one tablet of folic acid per day is sufficient. For women with severe abnormalities in folic acid metabolism, the daily dose of folic acid tablets needs to be increased, preferably under the guidance of a doctor.
