DPA

Also known as Docosapentaenoic acid, 22:5 n-3

DPA (docosapentaenoic acid) is a long-chain omega-3 fat that sits between EPA and DHA in the body's omega-3 pathway. It is found in fish and some meats and appears to share the heart and anti-inflammatory benefits of the better-known omega-3s.

Why it matters

What it does in your body

  • Intermediate between EPA and DHA in the body
  • Acts as a reserve that can convert to EPA
  • Supports heart and blood vessel health
  • Involved in tissue repair and inflammation resolution

Intake guidance

How much you need

There is no separate intake target for DPA. It is part of the long-chain omega-3 group and comes along with EPA and DHA in fish, so meeting general omega-3 guidance covers it.

What affects it

What affects your intake

Comes with other omega-3s

DPA is found alongside EPA and DHA in oily fish, so a fish-inclusive diet supplies it naturally.

Also in some meats

Unlike EPA and DHA, DPA is present in modest amounts in red meat, a minor source for meat eaters.

Emerging research

DPA is less studied than EPA and DHA but appears to offer similar cardiovascular benefits.

In practice

Good to know

Good to know: DPA is the quiet middle child of the omega-3 family, overshadowed by EPA and DHA but present in the same foods. Research suggests it carries similar benefits, and it can act as a reserve the body converts back to EPA. There is no need to seek it out separately; a diet with fish supplies it.

Where to get it

Best food sources

Salmon and oily fish, 3 ozmodest amount alongside EPA and DHA
Herring, 3 ozmodest amount
Fish oil supplementsmall amount in many products
Red meat, 3 ozsmall amount
Seal oil (traditional diets)notably high

The bottom line

DPA is a long-chain omega-3 that rides along with EPA and DHA in fish. Meeting your general omega-3 intake covers it, with no separate target.
