Role of folic acid (folate)
Folate supports cell division and growth. WHO and ACOG emphasize folic acid before and during early pregnancy to reduce risks related to neural tube development. Many people start supplements when planning pregnancy; if pregnancy is unexpected, ask your clinician about dose early.
Role of iron
Pregnancy increases blood volume and iron needs rise by trimester. Low iron can cause fatigue, anemia, and affect mother–baby health. WHO recommends daily iron supplementation for pregnant people in many areas with deficiency risk.
Food sources
Rich in folate: spinach, amaranth greens (rau dền), lentils, mung beans, oranges, folic-acid–fortified cereals.
Rich in iron: beef, liver (moderate amounts, well cooked), eggs, fish, tofu, black beans. Plant iron absorbs less than animal iron; vitamin C improves absorption.
Meal combination tips
- Pair leafy greens with orange or guava (ổi) at lunch.
- Avoid tea/coffee right after iron-rich meals (may reduce absorption).
- If prescribed iron tablets, some take them at night or away from morning milk to reduce stomach upset — follow personal instructions.
Supplements — what to know
- Do not self-increase folic acid or iron doses.
- Prenatal vitamins often combine several nutrients; bring them to prenatal visits to avoid duplication.
- Constipation from iron: drink water, increase fruit and vegetables, move gently; tell your clinician if discomfort persists.
When to test or follow up
Unusual tiredness, pale skin, breathlessness on stairs, dizziness — may relate to anemia. Routine blood tests during prenatal care help adjust early.
