Folic acid is usually not required for those without fertility requirements. It is only required for treatment of conditions such as folic acid deficiency anemia. Folic acid is an important participant in cellular life activities in the body. The reason why women need to take folic acid supplements during pregnancy is to prevent the occurrence of fetal neurological malformations. For people without reproductive requirements, folic acid in food is usually sufficient to meet the body’s needs, and there is usually no need to use the drug to supplement, so as to avoid overdose. However, if there is folic acid deficiency caused by megaloblastic anemia, chronic hemolytic anemia combined with folic acid deficiency, etc., the drug can be used under the guidance of the clinician for the treatment of anemia. It should be noted that if adverse reactions such as loss of appetite, nausea, abdominal discomfort occur during the use of the drug, it is recommended to go to the hospital for consultation.
