What is docosapentaenoic acid (DPA)?

Docosapentaenoic acid (DPA) is a long-chain omega-3 polyunsaturated fatty acid found in marine foods and fish oils. It is often described as an intermediary between EPA and DHA and may have its own biological effects.

What are the potential benefits of DPA?

DPA is associated with cardiovascular support and may help modulate inflammation. It may also support brain health, though much of the evidence is indirect or from non-human studies.

What foods contain DPA?

DPA is found in fatty fish and other marine foods, and it can be present in fish oil supplements. Amounts vary by species and product.

How much DPA should I take?

Common supplemental amounts are about 100–300 mg per day, depending on diet and goals. If you use omega-3 products, check labels because DPA is often listed separately from EPA and DHA.

Is DPA the same as EPA or DHA?

No—DPA is a distinct omega-3 fatty acid. The body can convert some EPA to DPA and some DPA to DHA, but conversion is limited and varies between individuals.

Moderate study situation·7/10

A higher score indicates better study conditions, but not necessarily effectiveness.

Docosapentaenoic acid (DPA) is an omega-3 fatty acid supporting cardiovascular, anti-inflammatory, and cognitive health, found in fish oil and marine foods.

Anti-inflammatory Cardiovascular Support Cognitive Enhancement Essential Nutrient Neuroprotective

dose range

100–300 mg

once daily with a meal containing fat

Consumption

Take DPA with a fat-containing meal for optimal absorption, usually as part of a fish oil blend.

Fat-soluble: take with fat.

Best time

Taking with first or second meal is preferred due to improved absorption with dietary fat.

Description

DPA is a long-chain omega-3 polyunsaturated fatty acid present in fatty fish and fish oils. It acts as an intermediary between EPA and DHA, contributing independently to health benefits such as reducing inflammation and supporting heart and brain function.

Note on evidence

Growing research links DPA with cardiovascular and anti-inflammatory benefits, but studies are less numerous compared to EPA and DHA.

Supports Cardiovascular Health

Moderate

Higher blood levels of DPA are associated with decreased risk of coronary heart disease and improved arterial function.

Safety & Information

Important safety information & known risks

For educational purposes only • not medical advice

DPA is generally well tolerated, with main safety concerns related to bleeding risk at high doses and in combination with blood-thinners or in people with bleeding disorders.

warning notices

May increase bleeding risk at high doses or with use of anticoagulants or antiplatelet drugs.
Do not use if allergic to fish or seafood.
Gastrointestinal symptoms (e.g., fishy aftertaste, mild nausea) may occur.
Avoid use if you have a fish or seafood allergy.
Do not use DPA supplements if you are taking anticoagulant or antiplatelet medications without clinician approval, due to increased bleeding risk.
Monitor for unusual bleeding or bruising if using high doses of DPA, particularly if you have a bleeding disorder.

CautionModerate

Why

Omega-3s, including DPA, can reduce platelet aggregation and prolong bleeding time.

recommendation

Consult a clinician before combining DPA supplements with blood-thinning medications; increased monitoring for bleeding may be necessary.

mechanisms of action

Brief explanations of how it works

Inhibition of Pro-inflammatory Mediators

DPA reduces pro-inflammatory cytokine production and supports the synthesis of specialized pro-resolving mediators involved in resolving inflammation.
