Questions about this ingredient

  • QIs it the same as anemia medication?

    Folic acid is also used to treat anemia caused by folate deficiency, but iron supplements are necessary for one of the common types of anemia, iron deficiency anemia, so they are not the same medication. If you have been diagnosed with anemia, please discuss with a doctor or pharmacist to determine the appropriate medication based on the cause.

  • QIs it too late to start taking it after confirming pregnancy?

    Folic acid is particularly important during the early stages of pregnancy when the fetal neural tube is forming, so it is generally recommended to start taking it from the planning stage of pregnancy. If you have already confirmed your pregnancy, it is advisable to start taking it now, but please discuss the dosage and duration with an obstetrician.
