Prenatal Nutrition Guide: What to Eat and Which Supplements to Take During Pregnancy

Pregnancy is one of the most nutritionally demanding seasons of a woman's life. Your body is building an entirely new human — and what you eat, and what you supplement with, directly shapes that baby's development, your energy levels, your mood, and your recovery. At WellnessRX Pharmacy in Bradford, RHN Nancy Tran works with expecting mothers to create personalized prenatal nutrition plans tailored to each trimester.

Pregnancy nutrition isn’t about perfection — it’s about giving your body and your baby the building blocks they need to grow, develop, and thrive. 🤍 From protein and healthy fats to key nutrients like folate, iron, DHA, and magnesium, small daily choices can make a meaningful difference for energy, recovery, and long-term health for both mom and baby.

Why Prenatal Nutrition Matters More Than Most People Realize

The first trimester — often when nausea makes eating difficult — is also when the baby's neural tube, heart, and major organs are forming. The third trimester sees the most rapid weight gain and mineral depletion. And the nutrient stores you build throughout pregnancy directly affect your postpartum recovery too.

The Core Prenatal Supplements — Pharmacist & RHN Approved

At WellnessRX, pharmacist Phillip Kim and Nancy Tran RHN review prenatal supplements together — to ensure what you take is both nutritionally effective and safe with any medications you're on.

1. Folate (not folic acid) — Methylfolate is the active form most effectively used by your body. Critical for neural tube development in the first trimester. Most prenatal vitamins use synthetic folic acid — ask us about active-form options.

2. Iron — Blood volume nearly doubles during pregnancy, increasing iron demands significantly. Iron deficiency is the most common prenatal deficiency and can cause fatigue, poor fetal growth, and increased delivery risk.

3. Omega-3 (DHA) — DHA is essential for fetal brain and eye development, especially in the third trimester. Most pregnant women don't get enough from diet alone.

4. Vitamin D3 — Supports fetal bone development, immune function, and reduces risk of gestational diabetes. Over 40% of Canadians are deficient before supplementing.

5. Magnesium — Helps prevent leg cramps, supports sleep quality, and regulates blood pressure during pregnancy. Often deficient even with a good diet.

6. Probiotics — Support digestion, reduce risk of gestational diabetes, and may lower risk of infant eczema and allergies when taken during pregnancy.

What to Eat During Pregnancy: Key Food Priorities

• Protein at every meal — eggs, legumes, fish, poultry, Greek yogurt. Supports fetal tissue growth and helps manage blood sugar.

• Leafy greens daily — spinach, kale, Swiss chard. Rich in folate, iron, calcium, and magnesium.

• Healthy fats — avocado, olive oil, wild salmon, walnuts. Supports brain development and hormone production.

• Complex carbohydrates — sweet potato, oats, brown rice. Steady energy, fibre, and B vitamins.

• Calcium-rich foods — dairy or fortified alternatives, sardines with bones, almonds. Critical for fetal bone and tooth formation.

Foods to Limit or Avoid During Pregnancy

• High-mercury fish (swordfish, shark, king mackerel) — replace with wild salmon, trout, or sardines

• Raw or undercooked meat, eggs, and sushi — listeria and salmonella risk is higher during pregnancy

• Excessive caffeine — limit to under 200mg/day (roughly 1–2 small coffees)

• Alcohol — no safe amount during pregnancy
