The American Pregnancy Association recommends that pregnant women consume at least 200-300 milligrams of DHA per day. This can be achieved through incorporating DHA-rich foods into their diet or by taking DHA supplements. It is important for pregnant women to meet their recommended daily intake of DHA to support their own health as well as the healthy development of their baby.

Recommended Daily Intake of DHA for Pregnant Women

During pregnancy, it is important for women to ensure they are getting enough DHA, or docosahexaenoic acid, in their diet. DHA is an omega-3 fatty acid that plays a crucial role in the development of the baby’s brain and eyes. The recommended daily intake of DHA for pregnant women is essential for the overall health and well-being of both the mother and the baby.

According to healthcare professionals, pregnant women should aim to consume at least 200-300 milligrams of DHA per day. This can be achieved through a combination of dietary sources and supplements. It is important to note that these recommendations may vary depending on individual circumstances, so it is best to consult with a healthcare provider to determine the specific needs for each pregnant woman.

To help pregnant women achieve the recommended daily intake of DHA, here are some examples of foods rich in this essential fatty acid:

Sources of DHA for Pregnant Women

Fatty Fish

Fatty fish such as salmon, trout, and sardines are excellent sources of DHA. These fish are not only rich in DHA but also omega-3 fatty acids, which play a crucial role in the development of the baby’s brain and eyes. It is recommended that pregnant women consume at least two servings of fatty fish per week to meet their DHA requirements.

Algal Oil Supplements

For pregnant women who cannot or do not consume fish, algal oil supplements are a great alternative source of DHA. Algal oil is derived from algae, which is where fish obtain their DHA from. These supplements provide a concentrated source of DHA and are suitable for individuals following a vegetarian or vegan diet.

Fortified Foods

Many food products such as milk, yogurt, eggs, and juices are now fortified with DHA. When shopping for groceries, look for labels that indicate “fortified with DHA” to increase your intake of this essential nutrient during pregnancy. However, it is important to note that these fortified foods may not provide as much DHA as natural food sources or supplements.

Incorporating these sources of DHA into a pregnant woman’s diet can help ensure that both the mother and her baby receive adequate levels of this important nutrient for optimal health and development.

Potential Risks of DHA Deficiency During Pregnancy

During pregnancy, it is crucial for women to ensure they are getting an adequate amount of DHA, as deficiency can lead to potential risks for both the mother and the baby. DHA, or docosahexaenoic acid, is an omega-3 fatty acid that plays a critical role in the development of the baby’s brain and eyes. Without enough DHA, there can be serious implications for both the pregnancy and the long-term health of the child.



1. Impaired Cognitive Development: DHA is essential for the development of the baby’s brain. Studies have shown that a lack of DHA during pregnancy can lead to impaired cognitive and motor function in children.

2. Preterm Birth: Research suggests that low levels of DHA in pregnant women may be associated with an increased risk of preterm birth. Premature babies are at higher risk for a range of health problems and developmental delays.

3. Postpartum Depression: There is evidence to suggest that lower levels of DHA during pregnancy may increase the risk of postpartum depression in new mothers. Adequate intake of DHA has been linked to a reduced risk of developing postpartum depression.

To mitigate these potential risks, it is important for pregnant women to focus on incorporating sources of DHA into their diet and consider supplementation if necessary.
