If you are trying to conceive or are already pregnant, you may have been informed by your doctor on the necessary supplements or medications that you need to take to ensure health and safety for you and the baby. Chances are you may have heard of DHA, but what is it exactly? What are its benefits and where can you purchase them?

What is prenatal DHA?
DHA stands for docosahexaenoic acid, which is an omega-3 fatty acid that is essential for brain development. Around 97% of the omega-3 fatty acids found in the brain are made up of DHA. DHA also makes up around 25% of the brain’s total fat content. As human beings, we naturally produce DHA in small quantities, which is insufficient for our daily requirements. Therefore, it is important to take in DHA through dietary sources, such as fish, meat or omega-3 rich eggs. DHA is also available as supplements, such as fish oil.
Prenatal refers to during or relating to pregnancy. When applied to supplements, this actually refers to a particular composition of the supplement, meaning that there is a difference between prenatal supplements, or vitamins, and regular ones. For instance, a prenatal vitamin may contain less vitamin A than the standard ones as high doses can be toxic to a developing fetus, but zinc levels and vitamin C levels are higher.
Therefore, a prenatal DHA is a dietary supplement specifically for pregnant women, and those trying to conceive, that contains DHA as its main component. But, despite this, it is still possible for women who are not pregnant to consume prenatal DHA or other prenatal vitamins.
Is prenatal DHA the same as a prenatal multivitamin?
The simple answer is no.
Prenatal DHA is a form of omega-3 polyunsaturated fatty acids while a prenatal multivitamin is a combination of a range of different vitamins that are typically found in foods and other natural sources. Minerals can also be contained in prenatal multivitamins. A prenatal multivitamin may also contain DHA as one of its components.
What are the health benefits of DHA?
The health benefits of DHA range from improved heart health, better vision, and reduced inflammatory response to enhanced neurodevelopment health and cognitive development.
Here are a few examples:
1. Brain health and eye health
Supplementing DHA during pregnancy is highly important as it ensures proper brain development in the baby. Several studies have been conducted to assess the impact of taking DHA and not taking DHA during pregnancy; what was found was that there are positive correlations between neurological development in infants and DHA supplementation.
For instance, in the journal Critical Reviews in Food Science and Nutrition, which was published in 2019, found that higher DHA levels resulted in better childhood neurodevelopmental health, while lower DHA levels linked to higher rates of autism spectrum disorders and attention-deficit/hyperactivity disorders.
Asides from reducing the chances of autism and ADHD, it also helps establish better problem-solving capabilities as well as better early visual acuity. This was found in separate studies by the American Journal of Clinical Nutrition on children of mothers who consumed DHA supplements or food during pregnancy versus mothers who did not.
As healthy brain development correlates with proper development of the nervous system, infants in the first six months of life require adequate amounts of DHA. Breastfeeding mothers may need to consume 200 mg to 300 mg of DHA a day, while infant formulas usually contain DHA already.
In a 2014 study published by the journal Nutrients, ensuring high levels of DHA is consumed during early childhood can lead to enhanced speed of performing mental tasks, memory retention and overall cognitive performance.
2. Mental health
DHA and EPA are both fats which support serotonin, a nerve messenger which helps balance one’s mood.
Based on a 2010 research review from Biological Psychiatry, people with depression were more likely to have low levels of DHA and EPA, concluding that DHA and EPA may help reduce depressive symptoms and act as a method of treatment towards depression. These fats also have anti-inflammatory effects on nerve cells, which may reduce depression risk as well.
3. Overall health
DHA provides a wide range of support to the body.
It promotes proper blood circulation and may help lower blood pressure, reducing the risk of heart attacks or stroke.
It assists in eye health – in a study, it was found that consuming 500 mg of DHA, as well as 1,000 mg of EPA, daily for three months decreased eye pressure by 8%, reducing the risk of glaucoma, which is an eye disease that gradually erodes vision. Furthermore, DHA can improve dry eyes and act as a form of treatment for retinopathy.
It helps reduce inflammation and balance out excessive inflammatory omega-6 fats, which are found in diets rich in soybean and corn oil. Due to its anti-inflammatory effects, this reduces the risk of chronic diseases that are common with age, such as heart disease; improve autoimmune conditions, such as rheumatoid arthritis, which causes joint pain; and help reduce muscle soreness and limitations in range of motion due to strenuous exercise.
Do you have to be pregnant or breastfeeding to take DHA? Can men take them too?
You do not have to be pregnant or breastfeeding to take DHA. Yes, men can take them too.
Consumption of DHA is allowed for anyone, as long as they are not allergic to omega-3 polyunsaturated fatty acids or soybeans, as they provide benefits during all stages of life. There are clear benefits to babies and children, as covered above, but also to teenagers, adults and seniors. For instance, numerous studies that have been conducted found that seniors with higher levels of omega-3’s, specifically DHA, have significantly less risk of developing diseases that affect the memory, such as dementia or Alzheimer’s.
However, this may differ for prenatal DHA, as it is not approved for use by anyone younger than 18 years old.
Before purchasing DHA supplements for yourself during or before pregnancy, be sure to consult with your doctor. Also inform your doctor if you have ever had or currently have:
- an allergy to fish or shellfish;
- liver disease;
- a heart rhythm disorder;
- a pancreas disorder; or
- an underactive thyroid.
Can you take too much prenatal DHA?
Firstly, the recommended minimum dose is mixed.
The American Pregnancy Association recommends pregnant women to take a daily prenatal DHA supplement that provides a minimum of 300 mg of DHA. The Food and Agriculture Organization of the United Nations (FAO) had released a paper in 2009 which contained recommendations of a minimum of 200-300 mg a day for pregnancy and lactation. On the other hand, some studies found that supplementation of less than 600 mg a day were not beneficial in preventing early preterm birth. To support this, at the 2018 International Congress on Vegetarian Nutrition (ICVN), evidence from recent studies were presented, showing that supplementation of 600 mg-1000 mg a day has correlated with lowered risk of pre-term delivery and higher birthweight, as well as a positive effect on brain development in the infant.
Therefore, it is highly crucial that you consult with your doctor beforehand to understand the right dosage for you, as consuming too much could lead to lesser benefit and potential harm to you and/or the baby.
If you think you or someone else may have overdosed on prenatal DHA, call your doctor or the Poison Control Center at (800) 222-1222 (for residents in the US only.)
What are the side effects from taking prenatal DHA?
There are side effects that may require immediate medical attention while others do not, meaning that they tend to go away on their own during treatment once the body adjusts to it. Although if the side effects continue or become bothersome, then check with a healthcare professional.
Side effects requiring immediate medical attention
- Bleeding gums;
- Consistent coughing and/or coughing up blood;
- Difficulty breathing and/or swallowing;
- Tightness in the chest;
- Dizziness and/or consistent headache;
- Irregular heartbeat;
- Hives, itching or skin rash in various parts or throughout the body;
- Sudden nosebleeds;
- Puffiness or swelling, particularly in the face area;
- Increased menstrual flow than usual or vaginal bleeding;
- Or red or dark brown urine.
Side effects not requiring immediate medical attention
- Loss of appetite;
- Nausea or vomiting;
- Bloated or passing of gas;
Which brand of prenatal DHA should I take?

Is algae-derived DHA superior to fish-derived DHA?
In the context of environmental sustainability, obtaining omega-3s, such as DHA, from algae-derived sources, is the best option. Our body absorbs in the same way, whether it is algae-derived or fish-derived.
Furthermore, it is somewhat safer to consume DHA from algae-based sources for its purity. For instance, a private supplement testing company named Labdoor had analyzed 54 of the best-selling fish oils on the market and found that every single product contained measurable levels of PCB, which are industrial contaminants that were widely banned in the 1980’s.
DHA is absolutely essential for brain development in infants and children, and can help maintain proper brain health in later years too. It is beneficial in many ways; not just for the brain, but for the whole body as it reduces the risk of various diseases that could affect different parts of the body, such as the heart. As a result, prenatal DHA is usually recommended for those trying to conceive or are already pregnant, to ensure that the baby grows optimally. Diet Standards prenatal DHA is, therefore, the perfect choice as it not only provides the necessary requirement of DHA, but is algae-derived, making it obtained in a clean, sustainable environment and 100% vegan.
