We all need omega-3 fatty acids for optimal health throughout our lives, and our need for them increases significantly during pregnancy and breastfeeding. These nutrients are crucial for the development of the fetal brain, eyes, and nervous system. After the baby is born, omega-3s continue to support brain development and immune function, while also promoting a healthy postpartum mood and overall well-being for mothers. Keep reading to discover more about these nutritional powerhouses!
What Are Omega-3 Essential Fatty Acids?
Omega-3s are a group of long-chain polyunsaturated fatty acids that are essential for health and development, similar to certain vitamins and minerals. However, our bodies cannot produce them, which means we must obtain omega-3s through our diet or supplements. Unfortunately, omega-3s are significantly lacking in the American food supply. In fact, the average American has one of the lowest intakes of omega-3s among developed nations, leading to widespread deficiency, especially among women. That’s why it’s often recommended for all women to take an omega-3 supplement derived from fish oil (or algae oil) during pregnancy.
Research indicates that the two most beneficial omega-3 fatty acids are EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). While EPA and DHA occur together and work in tandem within the body, studies reveal that each fatty acid has unique advantages. Documented health benefits of EPA and DHA include support for heart health, cognitive function, joint mobility, and healthy skin and hair, as well as a robust immune response.
During pregnancy and lactation, the research-backed benefits of omega-3s, particularly EPA and DHA, include aiding the healthy development of the fetal brain, eyes, and nervous system, promoting healthy birth weight and gestation duration, fostering a healthy immune system, and enhancing maternal mood and well-being. Additionally, these fatty acids can improve attention and concentration in infants and children.
Foods Rich in Omega-3 (EPA and DHA)
The best sources of EPA and DHA include cold-water fish such as salmon, tuna, sardines, anchovies, and herring. Many individuals are understandably concerned about mercury and other toxins found in fish, particularly during pregnancy. For this reason, purified fish oil supplements are often considered the safest source of EPA and DHA.
A high-quality fish oil supplement from a reputable manufacturer provides the health benefits of EPA and DHA without the risk of toxicity. Some people might think that flaxseed or flaxseed oil is a source of omega-3s, but flaxseed contains the shorter-chain omega-3, ALA (alpha-linolenic acid), which is different from the long-chain EPA and DHA. While it was once believed that the human body could convert ALA into the EPA and DHA we need, current research shows that this conversion is rare and inefficient. Fish oil or algae oil is a more reliable source of the essential EPA and DHA for optimal health.
Why Are Omega-3 Fatty Acids Important?
Adequate intake of omega-3 fatty acids is vital for maintaining the balance of hormone-like substances known as prostaglandins. Prostaglandins help regulate many important physiological functions, including blood pressure, blood clotting, nerve transmission, inflammatory and allergic responses, kidney functions, and gastrointestinal processes, as well as hormone production.
Depending on the type and amount of fatty acids we consume, certain prostaglandins can be produced in excess, while others may not be produced at all. This imbalance can lead to negative health consequences. The role of omega-3s in producing beneficial prostaglandins may explain their numerous health benefits, including promoting cardiovascular health, cognitive function, and immune response. Ongoing studies continue to identify more benefits of omega-3s for a wide range of health issues.
Why Are Omega-3s Especially Important During Pregnancy?
DHA omega-3 is generally recognized as the most crucial omega-3 during pregnancy, as it serves as a fundamental building block for the brain, retina, and nervous system. An increasing number of studies conducted on both human and animal infants show a correlation between omega-3 fatty acid consumption, particularly DHA, and cognitive and visual function, as well as overall brain development.
In humans, brain development experiences its most rapid and complex growth during the last trimester of pregnancy and the first two years after birth. Furthermore, studies indicate that infants whose mothers supplemented with DHA during pregnancy had healthier immune functions.

Summary
Omega-3 fatty acids are essential for health throughout life, with an increased need during pregnancy and breastfeeding. They support fetal development and maternal well-being. It’s crucial to obtain adequate omega-3s through diet or supplements, especially EPA and DHA, to reap the benefits for both mother and baby.
