Is a Vegetarian Mum Getting Enough Nutrition? 🌱

Written By Kelly Mak

Many mums-to-be choose a vegetarian diet for personal, cultural or ethical reasons. The good news? With thoughtful planning, a vegetarian diet can provide all the nutrients you and your baby need — before, during and after pregnancy.

However, there are a few nutrients that deserve extra attention, including protein, iron, calcium, vitamin B12, iodine and omega-3 fatty acids. Let’s break it down.

Protein: The Building Block of Growth

Protein is essential for your baby’s growth and development, as well as maintaining your own muscle and tissue health during pregnancy and breastfeeding.

Vegetarian mums can meet their needs by including:

  • Legumes like lentils, chickpeas, tofu and edamame

  • Nuts and seeds such as almonds, chia, and pumpkin seeds

  • Whole grains like quinoa, oats and brown rice

Tip: Incorporate different plant proteins throughout the day to achieve a balanced mix of essential amino acids.

Iron: Keeping Energy Levels Up

Iron helps carry oxygen through your blood, and during pregnancy, your needs almost double! Plant-based iron (non-heme iron) isn’t absorbed as efficiently as animal sources, so pairing it with vitamin C-rich foods can boost absorption.

Iron-rich vegetarian foods include:

  • Dried beans, lentils, tofu

  • Iron-fortified cereals

  • Leafy greens like spinach, bok choy, and kale

  • Nuts and seeds

👉 Pair with: oranges, strawberries, capsicum, or tomatoes for an iron-boosting combo.

Calcium: For Strong Bones and Teeth

Calcium helps build your baby’s bones and teeth, and also supports your own bone health.

Vegetarian sources include:

  • Dairy foods like milk, yoghurt, and cheese

  • Calcium-fortified soy milk or tofu

  • Almonds, tahini and sesame seeds

  • Dark leafy greens like broccoli and kale

If you follow a vegan diet, check that your plant milks and tofu are fortified with calcium.

Vitamin B12: The One You Can’t Miss

Vitamin B12 supports red blood cell formation and brain development — but it’s found only in animal products.

For vegan or dairy-free mums, this is one supplement you can’t skip.
Look for:

  • Vitamin B12-fortified plant milks, cereals or nutritional yeast

  • A vitamin B12 supplement, ideally discussed with your dietitian or GP

Iodine: Tiny Nutrient but Big Role!

Iodine helps your baby’s brain and nervous system develop. Even in a balanced diet, it’s hard to meet your needs without a supplement.

That’s why pregnancy and breastfeeding supplements containing iodine are recommended for all mums, including vegetarians.

Omega-3 Fats: Brain and Vision Support

Omega-3 fatty acids (especially DHA) play a key role in your baby’s brain and eye development.
While fish is the richest source, vegetarian mums can include:

  • Flaxseeds, chia seeds and walnuts

  • Algae-based omega-3 supplements (a great plant-based alternative to fish oil)

The Bottom Line

A well-planned vegetarian diet can absolutely support a healthy pregnancy and breastfeeding journey. Focus on variety, include fortified foods where possible, and don’t hesitate to use supplements for nutrients like vitamin B12, iodine and omega-3.

Every mum’s needs are unique, especially during pregnancy.
