Folic Acid is used to prevent or treat folate deficiency anemia and to help prevent birth defects in early pregnancy. It's also used in people with certain chronic conditions like malabsorption disorders.
Folic Acid is a type of B vitamin, specifically B9, that helps your body make new cells. It's especially important for pregnant women as it supports the healthy development of the baby. It also ensures cells replicate correctly, promoting healthy growth and development.
For adults, the usual dose of folic acid is 400 to 800 mcg daily. Pregnant women may be prescribed higher doses. For treating deficiency, doses can range from 1 to 5 mg per day depending on the severity. Folic acid is usually taken as a tablet, with or without food, at the same time every day.
Common side effects of folic acid include mild gastrointestinal upset such as nausea or bloating. High doses can mask symptoms of vitamin B12 deficiency. In rare cases, allergic reactions may occur.
People allergic to folic acid or any of its components should avoid it. Individuals with B12 deficiency should be careful since large doses of folic acid can hide symptoms of this condition. It's also important to note that folic acid can interact with certain medications like methotrexate, anticonvulsants, and sulfasalazine.
