Who is suitable for taking folic acid?

Folic acid is suitable for women preparing for pregnancy, pregnant women, lactating women, anemia patients and middle-aged and elderly people. Folic acid is a type of B vitamin that plays an important role in cell division and DNA synthesis. Its deficiency may lead to anemia or fetal neural tube defects.

1. Women preparing for pregnancy

Women preparing for pregnancy should start supplementing with folic acid 3 months before pregnancy, and the recommended daily intake is 400 micrograms. Folic acid helps reduce the risk of neural tube defects in the fetus, such as spina bifida and anencephaly. Taking folic acid regularly during pregnancy preparation can optimize maternal nutritional reserves. It is recommended to choose active folic acid or multivitamin preparations.

2. Pregnant women

Pregnant women's demand for folic acid increases to 600 micrograms per day, and they need to continue to supplement until they are 3 months pregnant. Folic acid is involved in placenta formation and fetal organ development, and deficiency may cause premature birth or fetal growth restriction. In addition to supplements, pregnant women can obtain natural folic acid from dark green vegetables, animal liver and other foods.

3. Breastfeeding women

Breastfeeding women need 500 micrograms of folic acid daily to provide nutrition to their babies through breast milk. Folic acid deficiency may lead to maternal megaloblastic anemia and affect milk quality. Supplementing folic acid during lactation should continue until weaning. You can choose a special nutrition package for pregnant and postpartum women containing folic acid.

4. Anemia patients

Patients with megaloblastic anemia need to supplement with a therapeutic dose of 1-5 mg of folic acid daily, usually in combination with vitamin B12. People with long-term digestive tract diseases or alcohol abuse are prone to folic acid absorption disorders and need to take medication supplements under the guidance of a doctor and increase their intake of folic acid-rich foods such as red meat and beans.

5. Middle-aged and elderly people

People over 50 years old need 400 micrograms of folic acid daily to help reduce homocysteine ​​levels and prevent cardiovascular and cerebrovascular diseases. Decreased gastrointestinal function in the elderly may affect the absorption of folic acid. It is recommended to choose active forms such as methyl folate, combined with vitamins B6 and B12 for better synergistic supplementation.

During folic acid supplementation, you should avoid taking it with anti-epileptic drugs and sulfa drugs. Alcohol will interfere with folic acid metabolism. The daily upper limit of folic acid for ordinary adults is 1,000 micrograms. Long-term excess may mask symptoms of vitamin B12 deficiency. It is recommended that supplementation needs be assessed through serum folate testing, and dosage adjustments may be required in patients with renal insufficiency. You can eat more natural sources of folic acid such as spinach, asparagus, and eggs every day. When cooking, avoid heating at high temperatures for long periods of time to reduce nutrient loss.
