How DHA Supports Fertility, Pregnancy, and Healthy Childhood Development
Getting the right nutrients is important for many expectant mothers. If you take a prenatal vitamin, check whether it contains DHA, an essential omega-3 fatty acid.
DHA is important for fetal growth and development. Studies show that DHA supplements may lower the risk of preterm birth. DHA can also help mothers. A 2020 review found that it may improve mood during late pregnancy and the early postpartum period.
DHA and Fertility: Enhancing Reproductive Health
Role of DHA in Hormonal Balance
DHA helps maintain hormone balance, which is important for reproductive health. It supports the hormones needed for fertility. In women, DHA supports hormonal regulation of ovulation and regular cycles. In men, it supports hormones that affect sperm health and function.
Impact of DHA on Egg Quality
DHA has a big impact on egg quality. It becomes part of the cell membranes in egg cells, making them healthier and work better. Healthy cell membranes support ovulation and increase the likelihood of fertilization. Getting enough DHA can improve egg quality and fertility.
Support for Sperm Health with DHA
DHA is also important for male fertility because it affects sperm health. It helps sperm move well and keeps their shape. Studies show that higher DHA levels are linked to better sperm movement and quality, which can help with conception.
Why is DHA Important During Pregnancy?
Docosahexaenoic acid (DHA) is an omega-3 fatty acid that is vital for mDocosahexaenoic acid (DHA) is an omega-3 fatty acid that helps keep all your cells healthy, especially in the brain, skin, and eyes.
During pregnancy, DHA is important for your baby’s development and health. Getting it through dietary sources or supplements is highly recommended during pregnancy.
DHA's Role in Fetal Development
Dara Godfrey, MS, RD, a registered dietitian at Reproductive Medicine Associates of New York, says DHA is important for several parts of fetal development, including:
- Brain development
- Eye development
- Nervous system development
Moreover, adequate DHA intake can help:
- Prevent preterm labor
- Ensure a healthy birth weight.
- Support a mother’s mood during the postpartum period.
Sherry Ross, MD, an OB-GYN and women’s health expert at Providence Saint John’s Health Center, points out that omega-3s like DHA and EPA are good for your health. DHA is found in the brain and may help with cognitive development and attention span in babies.
DHA's Impact Throughout Pregnancy
The fetal brain begins to develop in the first trimester, around 5 weeks, and continues to develop throughout pregnancy. DHA supports crucial brain structures each trimester:
- Cerebrum: Responsible for thinking, remembering, and feeling
- Cerebellum: Responsible for motor control
- Brain stem: Responsible for vital bodily functions
Because the brain is composed of a lot of fat and many nerve connections, DHA supports these processes during pregnancy. Brain growth is fastest in the third trimester, so it’s especially important to get enough DHA from food or supplements at this time.
What Can Happen with a DHA Deficiency?
Although research on DHA deficiency is ongoing, we know that not getting enough DHA during pregnancy can affect fetal development.
Studies suggest that taking DHA supplements may lower the risk of preterm birth, but more research is needed to understand the long-term effects of not getting enough DHA.
How to Increase DHA Intake
Eating foods rich in DHA and taking supplements can help you get enough. DHA is found in microalgae, a plant-based and sustainable source, but most people do not eat much of it. Many can benefit from DHA supplements made from microalgae oil.
Recommended Sources of DHA
If you want to get more DHA from your diet, try these options:
- Microalgae Oil: A natural and plant-based source of DHA.
- Fortified Foods: You can also look for dairy products and omega-3-enriched eggs that have added DHA.
Do You Need a Supplement?
Many experts recommend taking a DHA supplement daily, especially if your diet does not provide enough. Good prenatal vitamins should have at least 500-1,000 mg of DHA. It’s best to start taking these vitamins at least 3 months before you try to get pregnant.
Consult with your healthcare provider to determine whether a DHA supplement is right for you and whether they recommend any specific brands.
