Food for Your Third Trimester

Nutrient demands peak in the third trimester as your baby's bones harden, brain develops, and body prepares for life outside the womb. Here's what's happening to your body, the vitamins to prioritise, and what to avoid as you approach delivery.

What Happens to Your Body in the Third Trimester

  • Preparing for labour: Expect Braxton Hicks contractions, increased fatigue, and backaches as your baby grows rapidly.
  • Increased vaginal discharge: This is normal; a sudden rush of fluid may indicate your water breaking — contact your doctor immediately.
  • Peak nutrient demands: Your baby's bones harden, brain develops, and body stores iron for the first months of life during this stage.

Essential Vitamins for the Final Weeks

  • Vitamin K: Supports blood clotting, which is critical as you approach delivery — find it in leafy greens like kale and spinach.
  • Vitamin A: Supports your baby's vision, skin tissue development, and immune system — sourced from milk, eggs, and carrots.
  • Vitamin B12: Helps produce red blood cells and supports nervous system function — found in fish, meats, eggs, and dairy.
  • Vitamin C: Boosts iron absorption and provides antioxidant protection to strengthen maternal immunity.

The Role of DHA in Baby's Brain Development

  • Why DHA matters: DHA (Docosahexaenoic Acid) is found abundantly in the brain and plays a key role in brain and eye development during the third trimester.
  • Food sources: Indian mackerel, salmon, and tuna are good sources — aim for 2–3 servings of oily fish per week.
  • If fish intake is limited: A fortified maternal milk containing DHA can help bridge the gap.

Foods and Habits to Avoid

  • Caffeine and alcohol: Limit caffeine to under 200 mg per day and avoid alcohol entirely throughout the third trimester.
  • Foodborne risk: Skip raw or undercooked seafood, unpasteurised dairy, and deli meats to reduce the risk of foodborne infections.
  • Excessive salt: Avoid high salt intake, which can worsen swelling and contribute to elevated blood pressure.
  • Meal pattern: Eat small, frequent meals to manage heartburn and maintain steady energy levels as your body copes with increased demands.

Supporting Your Nutrition With Fortified Maternal Milk

  • Complete nutrition: Nestlé MOM is scientifically formulated with 20 vitamins and minerals — including folic acid, calcium, iron, vitamin A, and vitamin C — to support third trimester needs.
  • DHA content: Contains DHA (125 mg per 100g powder) to support your baby's brain development when dietary fish intake may be insufficient.
  • Gut health support: Nestlé MOM includes BIFIDUS BL — two types of beneficial bacteria that support gut health, which plays a role in maternal immunity and nutrient absorption.
  • Daily serving: Just 2 glasses a day helps provide energy, protein, and essential micronutrients to support you and your baby through the final weeks of pregnancy.
