Pregnancy is one of the most transformative journeys you'll ever experience. Your body is working incredible overtime, building another human from scratch. But here's something that might surprise you: what you eat during pregnancy doesn't just affect you, it's literally building your baby's brain, eyes, and nervous system. And one nutrient stands out as absolutely crucial for this developmental magic: Omega-3.
If you're plant-based, you've probably heard concerns about getting enough omega-3 during pregnancy. Let's cut through the noise and give you the science-backed facts you need.
Why Omega‑3 matters during pregnancy
Omega-3 is important for the development of baby's brain and eyes, especially during the latter stages of pregnancy. During the third trimester, your baby's brain is growing at an astonishing rate—accumulating around 70% of its structure during this critical period. The brain is made up of nearly 60% fat, and a significant portion of that is DHA, one of the key omega-3 fatty acids.
But the benefits don't stop at brain development. Research suggests that adequate omega-3 intake during pregnancy may support:
Visual development: DHA is a major structural component of the retina, and sufficient levels support healthy eye development
Nervous system formation: Omega-3s play a crucial role in the development of neurons and the protective myelin sheaths that surround them
Birth outcomes: Studies indicate that adequate omega-3 intake may support healthy birth weight and reduce the risk of premature birth
Maternal mental health: Some research suggests omega-3s may support mood regulation during pregnancy and postpartum
It is vitally important that mums-to-be get enough omega-3 essential fatty acids. Your baby will draw on your omega-3 stores regardless, which is why maintaining adequate levels benefits both of you.
Understanding fats, not all are created equal
Let's start with the basics. We consume three types of fats within our diets: saturated, monounsaturated, and polyunsaturated. Now, before your eyes glaze over at the chemistry lesson, stick with us—this matters more than you might think, especially if you're growing a tiny human.
Polyunsaturated fats are considered to be the good fats, and indeed are classed as "essential fatty acids" (PUFAs). The word "essential" isn't just marketing speak here—it means your body literally cannot make these fats on its own. You must get them from your diet. The key PUFAs are Omega-3 and Omega-6 (the 'omega' and the '3' or '6' relate to their chemical structures, but you don't need to worry about memorising that for the exam).
The forms of Omega‑3: ALA, EPA, and DHA explained
Here's where things get really important for plant-based mums. Not all omega-3s are the same, and understanding the difference is key to ensuring you're getting what you and your baby actually need.
ALA (Alpha-linolenic acid) is found in plant sources like flaxseeds, chia seeds, walnuts, and hemp seeds. While ALA is beneficial and an important part of a healthy diet, here's the challenge: your body needs to convert it into the more active forms—EPA and DHA. The catch? This conversion is remarkably inefficient, with only about 5-10% of ALA converting to EPA and less than 5% converting to DHA. During pregnancy, when your baby's demand for DHA is at its peak, relying solely on ALA conversion simply isn't enough.
EPA (Eicosapentaenoic acid) plays important roles in reducing inflammation and supporting cardiovascular health. During pregnancy, EPA also helps maintain your own health while your body works overtime.
DHA (Docosahexaenoic acid) is the star player for pregnancy. This is the form that makes up a significant portion of your baby's developing brain and retinal tissue. It's the omega-3 you absolutely need in adequate amounts during pregnancy and breastfeeding.
Practical ways to boost your Omega‑3 intake
High-quality algal Omega-3 supplements are the most effective and reliable way to meet your Omega-3 needs, especially during pregnancy. They provide the critical EPA and DHA forms directly, without relying on the body’s limited conversion process. A daily supplement ensures you meet recommended levels consistently, no matter what your meals look like.
Food can still play a supportive role. You can start your day with overnight oats topped with ground flaxseed and chopped walnuts. The slow-release energy from oats and the healthy fats offer a satisfying breakfast that supports steady blood sugar.
Lunch might include a quinoa salad with hemp hearts and sliced avocado over mixed greens. This combination delivers plant protein, fibre, and additional ALA to complement your supplement.
Smoothies remain an easy option for busy days. Blend fortified plant milk with berries, a tablespoon of ground flaxseed, and a handful of spinach for a nutrient-dense snack that tastes great while adding a little more ALA.
For dinner, consider tofu or tempeh stir-fries topped with chia seeds, or a warm soup finished with a swirl of flaxseed oil. These foods provide extra nutritional benefits, even though they cannot replace Omega-3 found in supplements.
Busting the myths about plant-based Omega‑3
Let's address the elephant in the room. You've probably been told that plant-based diets can't provide adequate omega-3 during pregnancy. This outdated information needs to be challenged. The truth is:
Myth: "You need fish for DHA."
Reality: Algae is the original source of DHA, and algal omega-3 supplements provide EPA and DHA directly—no conversion needed.
Myth: "Plant omega-3 isn't as good as fish oil."
Reality: Research shows that algal omega-3 is absorbed just as effectively as fish oil, and some studies suggest even better bioavailability.
Myth: "Flaxseeds are enough."
Reality: While flaxseeds are nutritious and a great source of ALA, the conversion rate to DHA is too low to meet pregnancy requirements. You need a direct source of DHA.
Beyond pregnancy, Omega‑3 for breastfeeding mums
The omega-3 story doesn't end at birth. If you're breastfeeding, your baby continues to rely on you for DHA. Breast milk DHA content directly reflects your dietary intake, so maintaining adequate omega-3 levels remains just as important during breastfeeding as it was during pregnancy.
Research suggests that adequate DHA in breast milk may support infant cognitive development, visual acuity, and immune function. Plus, maintaining your own omega-3 levels supports your recovery and wellbeing during those demanding early months of motherhood.
For breastfeeding mums, continuing with a high-quality algal omega-3 supplement ensures your baby receives optimal DHA while protecting your own stores from depletion.
