What you eat before pregnancy sets the foundation for a healthy baby. Start nourishing your body now.
Why Pre-Pregnancy Nutrition Matters
Your nutritional status at conception affects:
- Fertility and conception chances
- Early fetal development
- Pregnancy health
- Birth outcomes
- Baby’s long-term health
The first few weeks of pregnancy are critical – often before you know you’re pregnant. Starting supplements and healthy eating now ensures your baby gets what they need from day one.
Essential Supplements: Start 3 Months Before
Folic Acid (Most Important!)
Dosage: 400-800 mcg daily
Start: At least 3 months before conception
Why it’s critical:
- Prevents neural tube defects (spina bifida)
- 50-70% reduction in birth defects
- Needed in first 28 days (often before you know you’re pregnant)
- Supports rapid cell division
Higher dose (4-5 mg) if:
- You or partner has neural tube defect
- Previous baby with neural tube defect
- You take anti-epileptic medication
- You have diabetes
Food sources: Leafy greens, fortified cereals, beans, citrus fruits (but supplements are essential – you can’t get enough from food alone)
Iron
Why you need it:
- Builds blood volume for pregnancy
- Prevents anemia
- Reduces preterm birth risk
- Supports baby’s brain development
Dosage: 18-27 mg daily
Best absorbed with vitamin C – take with orange juice or citrus fruit.
Iron-rich foods: Red meat, spinach, lentils, fortified cereals, beans
Vitamin D
Why it matters:
- Supports fertility
- Reduces pregnancy complications
- Important for baby’s bone development
- Immune system support
Dosage: 600-1000 IU daily (some need more)
Get tested – many women are deficient.
Sources: Sunlight (15 minutes daily), fatty fish, fortified milk, supplements
Calcium
Why you need it:
- Baby’s bone and teeth development
- Prevents bone loss in mother
- Supports muscle and nerve function
Dosage: 1000 mg daily
Sources: Dairy products, fortified plant milk, leafy greens, almonds, sardines
Omega-3 Fatty Acids (DHA/EPA)
Why it matters:
- Baby’s brain development
- Reduces preterm birth risk
- Supports eye development
- May reduce postpartum depression
Dosage: 200-300 mg DHA daily
Sources: Fatty fish (salmon, sardines), walnuts, flaxseeds, omega-3 supplements
Choose low-mercury fish.
Choosing a Prenatal Vitamin
What to look for:
- 400-800 mcg folic acid (minimum)
- 18-27 mg iron
- 600-1000 IU vitamin D
- 1000 mg calcium (may need separate supplement)
- 200 mg DHA
- B vitamins
- Zinc and iodine
Start taking NOW – don’t wait until you’re pregnant.
Tips:
- Take with food to reduce nausea
- If constipated from iron, increase fiber and water
- If one brand bothers you, try another

Achieving Ideal Weight
Target BMI: 18.5-24.9
Why weight matters:
- Underweight (BMI < 18.5): May not ovulate regularly, higher preterm birth risk
- Overweight (BMI 25-29.9): Reduced fertility, higher pregnancy complications
- Obese (BMI ≥ 30): Significantly reduced fertility, increased risks
If You Need to Lose Weight
Safe strategies:
- Lose 0.5-1 kg per week
