The Importance of Docosahexaenoic Acid (DHA) During Pregnancy

September 1st, 2023

Proper nutrition during pregnancy is vital for the well-being of the mother and the developing baby. Expecting mothers can benefit greatly from following a well-balanced diet that emphasizes nutrients that help the overall pregnancy and long-term development of the child.

Among these essential nutrients, there is a particular emphasis on Omega3s, such as Docosahexaenoic Acid (DHA). Understanding the significance of these nutrients and including them in the maternal diet can help expecting mothers improve their health and contribute to the growth and development of their babies.

Read on to learn more about the importance of DHA during pregnancy and how to incorporate it into a well-rounded diet.

What is DHA?

Docosahexaenoic acid, or DHA, is a major omega-3 fatty acid. Omega-3s are polyunsaturated fats that support eye, heart, and brain health. While omega-3 fatty acids are essential to our health, our bodies cannot produce them, meaning we must obtain them from dietary sources.

DHA is primarily found in fatty fish, such as salmon, mackerel, sardines and tuna, along with certain algae. It is a vital structural component of cell membranes in the brain, retina, and sperm cells. DHA, in particular, also plays a crucial role in brain development and function.

Additionally, there are two other omega-3 fatty acids: EPA (Eicosapentaenoic Acid) and ALA (Alpha-Linolenic Acid). EPA primarily supports heart health by reducing inflammation and improving blood vessel function. 

ALA is a plant-based omega-3 fatty acid that primarily focuses on reducing the risk of heart disease and supporting overall well-being; however, its conversion into the more biologically active forms is limited in humans.

The Importance of Sufficient DHA During Pregnancy

DHA is critical to fetal brain development and cognitive function. During pregnancy, the mother transfers DHA to the developing fetus, contributing to the formation of the baby's brain and nervous system. Adequate DHA intake during pregnancy and breastfeeding can improve cognitive outcomes in children, enhancing attention and learning abilities.

DHA is also essential for the structural integrity of brain cells and fosters the development of neural connections and the production of neurotransmitters (chemical messengers in the brain that facilitate communication between brain cells). Ensuring sufficient DHA during pregnancy through maternal diet or supplementation is essential for promoting healthy cognitive function in children.

Brain Development

DHA plays a critical role in supporting brain development and cognitive function. Research shows that DHA is essential for the structural integrity of brain cells and for forming neural connections. Getting enough DHA during pregnancy and early childhood is linked to better cognitive function, memory, and problem-solving skills.

Eye Health

DHA is also crucial for supporting eye health and babies' visual development, as the retina contains high levels of DHA. Studies demonstrate that one of the effects of DHA intake during pregnancy is improved infant visual acuity. Adequate DHA intake contributes to the retina's development and helps protect against age-related macular degeneration, a leading cause of vision loss among older adults.

Full-Term Pregnancies

Additionally, research suggests that DHA supplementation plays a role in reducing preterm birth rates. Studies find that pregnant women who consume higher amounts of DHA have a decreased risk of premature delivery. Scientists believe that DHA's anti-inflammatory properties, influence on uterine blood flow, and impact on prostaglandins contribute to preventing preterm labor, although more research is needed.

Maternal Health Benefits

In addition to its effects on fetal development, DHA supplementation during pregnancy can potentially benefit mothers. Research suggests that DHA may reduce the risk of postpartum depression. It has also been associated with improved cognitive function in mothers and a potential protective effect against age-related cognitive decline. DHA supplementation is also linked to maternal well-being, including improved cardiovascular health and reduced inflammation.

How Much DHA Do You Need During Pregnancy?

We recommend taking a supplement with at least 200 mg of DHA daily during pregnancy. Another way to achieve this is to eat between 1 to 2 servings of fatty fish per week, which are rich in DHA.

What Can Result From a DHA Deficiency?

While research in this area is limited, some evidence suggests insufficient DHA during pregnancy can compromise fetal development; however, the long-term implications are not yet fully understood.

Taking Prenatals with DHA

DHA supplementation is invaluable for expecting mothers to meet their nutritional goals during pregnancy. Prenatal vitamins with added omega-3s can help ensure an adequate intake of DHA.

When choosing prenatal vitamins with DHA, consider the quality and purity of the DHA source to ensure the safety and effectiveness of the supplement. Look for reputable brands that prioritize sourcing from reliable and sustainable fish or algae sources. Third-party testing and certifications can provide additional assurance of product quality.

Many professionals recommend taking prenatals with DHA as soon as you begin planning for pregnancy or find out you are pregnant. This early initiation helps ensure that your body has sufficient levels of DHA from the earliest stages of fetal development, supporting your baby's overall growth and well-being.

Remember to consult your healthcare provider for personalized recommendations based on your specific health needs and circumstances.

How to Incorporate DHA into Your Diet

Various dietary sources of DHA can be incorporated into your meals during pregnancy. Some options include:

1. Fatty Fish and Seafood

Incorporating fatty fish such as salmon, mackerel, sardines, and tuna into your diet can provide significant amounts of DHA. Shoot for 2-3 servings per week to meet your DHA requirements. 

2. Supplements

DHA supplements, such as fish oil or algae oil capsules, are available for those who may not consume enough DHA in their diet. These supplements can benefit individuals who don't eat fish or have specific dietary restrictions. Always consult with your healthcare provider beforehand for personalized recommendations on dosage and brand. 

3. Vegan and Vegetarian Sources

For mothers following vegetarian or vegan diets, many plant-based sources of omega-3 fatty acids can provide ALA, which the body can partially convert to DHA. 

Good sources include flaxseeds, chia seeds, hemp seeds and walnuts. However, it's important to note that the conversion rate of ALA to DHA is limited, so considering DHA supplementation may be beneficial.
