If you are pregnant, trying to conceive, or planning ahead, you have probably heard omega-3 fatty acids mentioned in conversations about prenatal nutrition. But what exactly are they, why do they matter, and how do fish oil, DHA, EPA, and algae-based options fit into the picture?

This article breaks down what to know about omega-3 during pregnancy, common food sources, supplement considerations, and questions to discuss with your healthcare provider.

Why Omega-3 Fatty Acids Are Important During Pregnancy

Omega-3s are a type of polyunsaturated fatty acid. Because the body does not make enough of certain omega-3s on its own, they usually need to come from food or supplements.

During pregnancy, two commonly discussed forms are DHA, or docosahexaenoic acid, and EPA, or eicosapentaenoic acid. DHA is found in high amounts in the brain and retina, which is why it is often included in conversations about normal fetal brain and eye development.

Omega-3s are one part of a broader prenatal nutrition plan. They should not be presented as a guarantee of any specific pregnancy, birth, postpartum, or developmental outcome.

DHA and EPA: What Each One Does

When people talk about omega-3 during pregnancy, they are often referring to DHA and EPA.

DHA is commonly discussed because it contributes to normal fetal brain and eye development. It is found in the brain and retina and is often included in prenatal nutrition recommendations.

EPA is another omega-3 fatty acid that is often found alongside DHA in fish oil and other marine-based supplements. EPA and DHA may be included together in some supplement formulas, while other products focus mainly on DHA.

The right balance for you may depend on your diet, supplement routine, health history, and provider recommendations.

What the Research Says About Omega-3 and Pregnancy

Omega-3 intake during pregnancy has been widely studied in relation to maternal nutrition, fetal development, and pregnancy outcomes. Some research has explored whether omega-3 status may be associated with certain pregnancy-related outcomes, but findings can vary depending on the study design, dosage, timing, baseline nutrient status, and individual health factors.

For compliance purposes, it is important to avoid saying or implying that omega-3 supplements can prevent preterm birth, improve birth weight, treat inflammation, reduce postpartum depression, or guarantee better outcomes for the baby.

A balanced way to describe the research is this: omega-3 fatty acids, especially DHA, are important nutrients during pregnancy, and many healthcare providers discuss them as part of prenatal nutrition. Any supplement decision should be made with professional guidance.

How Much Omega-3 Do You Need During Pregnancy?

Omega-3 needs can vary depending on your diet, pregnancy stage, health history, and provider guidance. Many prenatal nutrition conversations focus on DHA because of its role in normal fetal brain and eye development.

Instead of relying on a general number alone, check your prenatal vitamin or omega-3 supplement label and ask your healthcare provider whether the amount is appropriate for you.

This is especially important if you:

• Do not eat fish or seafood
• Follow a vegetarian or vegan diet
• Take multiple supplements
• Have a bleeding disorder or take blood-thinning medication
• Have food allergies
• Are you pregnant, breastfeeding, or postpartum
• Have been given specific nutrition recommendations by your provider

Your provider can help you decide whether omega-3s should come from food, a prenatal vitamin, a separate DHA supplement, fish oil, or an algae-based option.

Food Sources of Omega-3 During Pregnancy

Omega-3s can come from both animal-based and plant-based foods. However, the type of omega-3 matters.

DHA and EPA are found mainly in fish and seafood. Common lower-mercury options may include salmon, sardines, trout, herring, and anchovies. If you eat fish during pregnancy, ask your healthcare provider which types and amounts are appropriate.

ALA, or alpha-linolenic acid, is a plant-based omega-3 found in foods such as:

• Flaxseeds
• Chia seeds
• Walnuts
• Hemp seeds
• Flaxseed oil
• Canola oil

ALA is not the same as DHA or EPA. The body can convert some ALA into longer-chain omega-3s, but the conversion may be limited. If you do not eat fish, ask your provider whether an algae-based DHA supplement may be appropriate.

Fish Oil During Pregnancy: What to Know

Fish oil supplements are one common way people add DHA and EPA to their prenatal routine. However, not every fish oil supplement is the same.

When evaluating a fish oil supplement, consider asking your healthcare provider about:

• The amount of DHA and EPA per serving
• Whether the product is third-party tested
• Whether it has been screened for contaminants
• Whether it fits with your current prenatal vitamin
• Whether it is appropriate for your health history or medications
• Whether the taste, smell, or capsule size is realistic for you

Avoid making assumptions based only on front-label claims. The supplement facts panel and quality testing details matter.

Getting Enough Omega-3 If You Do Not Eat Fish

Not everyone eats fish or seafood. Some people avoid it because of taste preferences, allergies, dietary restrictions, vegan or vegetarian eating patterns, food aversions, or mercury concerns.

For people who do not eat fish, algae-based DHA supplements may be worth discussing with a healthcare provider. Algae-based DHA can provide a non-fish source of DHA and may be suitable for some vegetarian or vegan routines.

Plant foods such as walnuts, chia seeds, and flaxseeds can still be part of a balanced diet, but they mainly provide ALA rather than DHA or EPA. Your provider can help you decide whether food sources alone are enough or whether a supplement should be considered.

What to Look for in a Prenatal Supplement

Many prenatal vitamins do not include DHA or EPA, while others include them in varying amounts. That is why it is important to review the supplement facts panel carefully.

When comparing prenatal or omega-3 supplements, look at:

• Whether DHA is included
• Whether EPA is included
• The amount per serving
• The source, such as fish oil or algae
• Third-party testing or purity information
• Allergen information
• Added flavors, sweeteners, or fillers
• Serving size and frequency
• Whether the format is something you can take consistently

A supplement is only useful if it fits your provider’s recommendations and your real-life routine.

Format Matters, Especially If Pills Are Hard to Take

Prenatal supplements come in many forms, including capsules, softgels, gummies, liquids, and powders. Each format has trade-offs.

Fish oil capsules may work well for some people, while others may find the smell, taste, or capsule size difficult. Gummies may be easier to take, but they may not include the same nutrients or amounts as other formats. Powders and drink mixes may feel more manageable for people who prefer not to swallow pills.

Storkling’s prenatal drink supplement may be worth considering if you prefer a drink-based format as part of your prenatal routine. It was designed with real pregnancy experiences in mind, including pill fatigue and changing food preferences.

As with any supplement, review the full ingredient list and supplement facts panel with your healthcare provider to make sure it fits your individual needs.

Frequently Asked Questions

When should I start thinking about omega-3 during pregnancy?

Many people discuss prenatal nutrition before pregnancy or as early as possible in pregnancy. If you are trying to conceive, pregnant, breastfeeding, or postpartum, ask your provider whether DHA or other omega-3s should be part of your routine.

Can I get enough omega-3 from food alone?

Some people may get enough omega-3s from food, especially if they regularly eat provider-approved, lower-mercury fish. Others may need to discuss supplementation because of dietary restrictions, food aversions, allergies, or limited seafood intake.

Are there risks and benefits I should discuss with my healthcare provider?

Yes. Omega-3 supplements may not be appropriate for everyone, especially at higher doses or for people taking certain medications. Ask your healthcare provider before starting or changing your supplement routine.

Does omega-3 help with postpartum mood?

Omega-3s have been studied in relation to maternal nutrition and mood, but they should not be described as a treatment or prevention strategy for postpartum depression or other mood disorders. If you are experiencing mood changes, anxiety, depression, or thoughts of harming yourself, contact a healthcare professional right away.

What if my prenatal vitamin does not include DHA?

If your prenatal vitamin does not include DHA, ask your provider whether you should add DHA through food, a separate supplement, or another prenatal formula. Do not add multiple overlapping supplements without professional guidance.

Questions to Ask Your Healthcare Provider

Before choosing or changing an omega-3 supplement, consider asking:

• Does my current prenatal vitamin include DHA or EPA?
• How much DHA should I aim for during pregnancy or breastfeeding?
• Can I get enough omega-3 from food?
• Should I consider fish oil or algae-based DHA?
• Are there any fish or seafood options I should avoid?
• Are omega-3 supplements safe with my medications or health history?
• Is a drink-based prenatal supplement a good fit for my routine?

These questions can help you make an informed decision based on your specific needs rather than relying on general supplement claims.

Conclusion

Omega-3 fatty acids are important nutrients often discussed during pregnancy, especially DHA, because it contributes to normal fetal brain and eye development. Food sources such as lower-mercury fatty fish can provide DHA and EPA, while algae-based options may be considered for people who avoid fish.

If your current prenatal routine does not include omega-3s, talk with your healthcare provider about whether food sources, fish oil, algae-based DHA, or another supplement format may be appropriate. A drink-based prenatal option like Storkling may be worth discussing if traditional pills are difficult to take, but it should be used as part of a broader prenatal care plan guided by a licensed professional.
