During pregnancy, your baby’s brain is developing at lightning speed—and what you eat can make a big difference. Among all the nutrients that support a growing baby, omega-3 fatty acids, especially DHA (docosahexaenoic acid)and EPA (eicosapentaenoic acid), play a starring role.
If you’ve ever heard someone say, “Eat more fish for a smarter baby,” this is what they’re talking about.
But what are DHA and EPA exactly? How much do you need during pregnancy? And what’s the best—and safest—way to get them? This post will walk you through everything you need to know.
🧠 Why DHA and EPA Matter for Your Baby
DHA and EPA are types of omega-3 fatty acids that are essential for many aspects of health—but they’re especially important during pregnancy.
✅ DHA: The Brain Builder
DHA is a major building block of your baby’s brain, eyes, and nervous system. It helps form the structure of the brain and is involved in cognitive development from the very beginning.
Studies show that babies whose mothers consumed enough DHA during pregnancy had better problem-solving and visual acuity in infancy.

✅ EPA: The Helper
EPA supports DHA’s transfer from mom to baby and plays a role in reducing inflammation and improving circulation during pregnancy. It also supports heart health and immune function.
📊 How Much DHA & EPA Do You Need?
Experts recommend 200–300 mg of DHA per day during pregnancy, although many prenatal vitamins don’t include enough on their own.
A study published in The American Journal of Clinical Nutrition suggests that consistent omega-3 intake during pregnancy may reduce the risk of preterm birth and low birth weight.

🤔 Common Questions
❓ Can I get enough omega-3s from food alone?
It depends. Many people fall short unless they eat fish regularly. A high-quality supplement can help fill in the gaps.
❓ Are omega-3s only good for the baby?
Not at all! Omega-3s also:
- Reduce mom’s risk of postpartum depression

💬 A Final Thought
Giving your baby a head start begins with what you nourish yourself with. DHA and EPA aren’t just nutrients—they’re part of the story you’re writing for your child’s development. By choosing foods rich in omega-3s or taking a quality supplement, you’re supporting your baby’s ability to think, see, and thrive—even before they’re born.
