Compare Liquid Omega-3 Oils by Label Facts
Serving size, oil source, total omega-3, EPA, DHA, DPA, and combined EPA and DHA can all vary by product. These label facts are the clearest way to compare liquid omega-3 oils serving by serving.
Marine omega-3 sources
Fish oil, cod liver oil, and algae oil are all marine-derived omega-3 sources.
Serving size matters
Compare omega-3 amounts by serving, not by bottle size.
EPA and DHA
EPA and DHA are two long-chain marine omega-3 fatty acids listed on many labels.
Total omega-3
Total omega-3 may include EPA, DHA, DPA, and other omega-3 fatty acids.
Combined EPA and DHA
Combined EPA and DHA shows the two main marine omega-3 fatty acids added together.
Product source
Fish-based and vegan oils can have different EPA and DHA profiles.

What Is Liquid Omega-3 Oil?
Compare the serving, not the bottle
Liquid omega-3 oil is an omega-3 supplement taken by a measured spoon serving instead of capsules. This format can help shoppers compare the amount of omega-3 per serving without calculating capsule counts.
Liquid omega-3 oils can come from different marine-derived sources. Fish oil and cod liver oil are fish-based marine omega-3 sources, while algae oil is a non-fish marine omega-3 source commonly used in vegan omega-3 products.
How to read the label
- Check the serving size in mL or teaspoons.
- Check total omega-3 per serving.
- Compare EPA and DHA separately.
- Check DPA if the label includes it.
- Review combined EPA and DHA per serving.
- Compare products serving by serving, not by bottle size.
MARINE OMEGA-3 SOURCES
Compare Liquid Omega-3 Oils by Source
Fish oil, cod liver oil, and vegan algae oil can all provide marine omega-3 fatty acids. The clearest comparison starts with the source, then looks at serving size, total omega-3, EPA, DHA, DPA, and combined EPA and DHA per serving.
Fish Oil
Fish oil is a fish-based marine omega-3 source. Liquid fish oil products usually provide EPA and DHA in the same serving, but the exact balance can vary by formula.
Cod Liver Oil
Cod liver oil is also fish-based, but it comes from cod liver rather than standard fish oil sources. Cod liver oil may have a different EPA and DHA profile than standard fish oil.
Vegan Algae Oil
Vegan algae oil is a non-fish marine omega-3 source. Algae oil is commonly used in vegan omega-3 products and can provide EPA, DHA, or both, depending on the formula.
What Do EPA and DHA Mean?
EPA and DHA are two long-chain marine omega-3 fatty acids, but they are not the same fatty acid. EPA stands for eicosapentaenoic acid, and DHA stands for docosahexaenoic acid. Both are found in marine foods and marine-based omega-3 supplements, including fish oil and algae oil.
How EPA and DHA differ
EPA and DHA work together, but they are commonly discussed for different focus areas in the body. EPA is often discussed in relation to cardiovascular health and inflammatory processes. DHA is highly concentrated in the brain and retina and is often discussed in relation to brain and eye health.²
The practical label-reading difference is the amount of EPA and DHA listed per serving. Some liquid omega-3 oils provide more EPA than DHA, while others provide more DHA than EPA.
EPA and DHA on the label
- EPA: eicosapentaenoic acid, one of the main marine omega-3 fatty acids listed on many supplement labels.
- DHA: docosahexaenoic acid, the other main marine omega-3 fatty acid listed on many supplement labels.
- EPA and DHA together: the two numbers many shoppers compare when reviewing omega-3 products.
- Amount per serving: the most useful way to compare EPA and DHA across liquid omega-3 oils.
- Formula balance: some products provide more EPA, while others provide more DHA.
What Is the Difference Between Total Omega-3 and Combined EPA and DHA?
Total omega-3 is the full omega-3 amount listed on the product label, while combined EPA and DHA is the EPA amount plus the DHA amount per serving. These numbers are related, but they are not the same number.
What total omega-3 means
Total omega-3 may include EPA, DHA, DPA, and other omega-3 fatty acids. This number shows the full omega-3 amount listed on the label, but it does not always show how much EPA and DHA the product provides.
Why combined EPA and DHA matters
Combined EPA and DHA is useful for side-by-side label comparison because it shows the two main marine omega-3 fatty acids shoppers usually review. Two products may both list 2,000 mg total omega-3 per serving, but one may contain more EPA while the other contains more DHA.

Frequently Asked Questions About Liquid Omega-3 Oils
What is liquid omega-3 oil?
Liquid omega-3 oil is an omega-3 supplement taken by a measured spoon serving instead of capsules. Liquid omega-3 oils may come from fish oil, cod liver oil, or vegan algae oil. The most useful comparison points are serving size, total omega-3, EPA, DHA, DPA, and combined EPA and DHA per serving.
What is the difference between EPA and DHA?
EPA and DHA are two long-chain marine omega-3 fatty acids, but they are not the same fatty acid. EPA stands for eicosapentaenoic acid, and DHA stands for docosahexaenoic acid. EPA is commonly discussed in relation to cardiovascular health and inflammatory processes, while DHA is highly concentrated in the brain and retina and is commonly discussed in relation to brain and eye health.
Should I compare total omega-3 or combined EPA and DHA?
Compare both numbers because total omega-3 and combined EPA and DHA answer different label-reading questions. Total omega-3 shows the full omega-3 amount listed on the label. Combined EPA and DHA shows the amount of the two main marine omega-3 fatty acids shoppers usually compare.
What is the difference between fish oil and vegan omega-3 oil?
Fish oil products are fish-based marine omega-3 products, while vegan omega-3 oil products are usually algae-based marine omega-3 products. Both can provide EPA and DHA, but the exact amounts depend on the formula. The clearest comparison is serving size, total omega-3, EPA, DHA, DPA, and combined EPA and DHA per serving.
Is cod liver oil the same as fish oil?
Cod liver oil is fish-based, but it is usually compared separately from standard fish oil because it comes from cod liver. A cod liver oil may have a different EPA and DHA profile than a standard fish oil. The most reliable comparison is the product label.
How do I compare liquid omega-3 oils with different serving sizes?
Compare liquid omega-3 oils with different serving sizes by starting with the amount of oil taken per serving. A product with a larger serving size may list more omega-3 per serving, so the serving size should be reviewed before comparing total omega-3, EPA, DHA, DPA, and combined EPA and DHA.
Is more EPA or more DHA always better?
More EPA or more DHA is not automatically better. Some liquid omega-3 oils provide more EPA, while others provide more DHA. A sufficient comparison should review the full label rather than one number alone.
