When it comes to omega-3s, you’ve most likely heard of EPA and DHA. They’re those listed on most fish oil dietary supplements and typically talked about for coronary heart and mind well being. But just lately, I got here throughout one thing I hadn’t heard a lot about earlier than – DPA, typically known as the “lacking omega.”
I used to be curious. What is DPA? What does it really do? And extra importantly, do we actually want it? I began digging into the analysis, searching for actual solutions backed by science – not hype. Here’s what I discovered.
What DPA really is (and what it isn’t)
DPA stands for docosapentaenoic acid, however don’t fear, you don’t want to bear in mind the total identify. What’s useful to know is that DPA is without doubt one of the lesser-known omega-3 fatty acids, together with the extra well-known EPA and DHA.
These three are carefully linked. You can consider them as rungs on a ladder:
EPA → DPA → DHA
Your physique provides just a little piece to EPA to make DPA (with assist from a particular enzyme known as ELOVL2), then provides yet one more step to make DHA. And apparently, it may additionally go backwards – changing some DPA again into EPA when wanted.
This makes DPA a form of built-in reserve that your physique can faucet into to help coronary heart and immune well being.
Common misunderstandings about DPA
Now, let’s clear up just a few widespread mix-ups:
- DPA is an omega-3, not omega-6, omega-9, or the rest. It belongs to the identical household as EPA and DHA.
- It’s not a “weaker” or pointless omega-3. In truth, new analysis reveals that DPA might need its personal distinctive advantages, separate from the others. We’ll get into these within the subsequent part.
- Often left off labels, however nonetheless current. Many fish-oil merchandise include DPA even when it isn’t listed; an in depth lab report will normally present it.
And simply to be clear: DPA is of course discovered within the physique, particularly in blood vessels, breast milk, and sure components of the mind. It’s not artificial or man-made.
So whereas it’s not as well-known as EPA or DHA, DPA may be very a lot an actual, naturally occurring omega-3, and it might be enjoying a quiet however essential position in your well being.
Do we actually want it?
There’s no official “day by day dose” of DPA – but.
Health pointers haven’t set a selected DPA quantity but. In Australia, for instance, the NHMRC teams DPA along with EPA and DHA beneath ‘lengthy‑chain omega‑3s’, however it doesn’t give it its personal quantity.
Still, analysis is beginning to level towards a job for DPA, particularly when it comes to coronary heart well being.
A big 2024 examine involving over 300,000 adults discovered that folks with the best ranges of EPA, DPA and DHA of their blood had been about 45% much less doubtless to die instantly from heart-related causes than these with the bottom ranges.
Another examine checked out individuals with kidney failure who had simply began dialysis (a therapy that filters the blood when the kidneys can’t). In that high-risk group, these with extra DPA of their blood had been about one-third much less doubtless to die instantly from coronary heart issues inside their first yr of therapy – even after adjusting for age, food regimen and different well being elements.
These research don’t show DPA prevents coronary heart points by itself, however they do counsel it may be a useful a part of the combination, particularly alongside EPA and DHA.
DPA may act as a “back-up” for EPA
Your physique can convert some DPA again into EPA if it wants to. In one small human trial the place individuals took a pure DPA complement, not solely did their DPA ranges rise, however EPA ranges elevated too – which reveals your physique can draw on DPA when wanted.
Bottom line:
There’s no official goal for DPA but, however early analysis suggests it helps coronary heart well being – and could assist maintain your general omega-3 ranges balanced. Whether by way of meals or dietary supplements, getting some DPA in your food regimen seems to be like a wise transfer.
What are all the advantages of DPA?
We’ve already seen how DPA may help coronary heart well being – now let’s break down the total vary of doable advantages backed by analysis.
1. Supports coronary heart well being
Beyond its hyperlink to fewer cardiac occasions, DPA can be related to decrease triglycerides and ldl cholesterol – two forms of fats within the blood which can be linked to coronary heart illness.
It may additionally assist scale back irritation in blood vessels, and some research even join it to much less plaque build-up within the arteries (generally known as atherosclerosis), particularly in older adults.
2. Helps maintain blood stream in test

This might assist decrease the chance of blood clots and help healthy circulation.
3. May help blood sugar steadiness
In early animal research, DPA-rich oils helped decrease blood sugar and enhance how the physique processes fat and glucose. It’s nonetheless early days, however it factors to potential advantages for metabolic well being and circumstances like insulin resistance.
4. Might help mind well being as we age
In a U.S. examine of adults over 60, these with increased ranges of DPA of their blood scored higher on reminiscence and considering assessments, particularly after age 70.
Other analysis has discovered that folks with despair or different psychological well being points typically have decrease DPA ranges. Animal research counsel DPA could assist shield the mind from irritation, ageing, and mood-related adjustments.
5. May assist scale back continual irritation
DPA additionally performs a job in serving to the physique relax irritation. It’s been proven to help tissue restore, scale back inflammatory indicators, and assist make particular compounds that the physique makes use of to resolve irritation – not simply battle it.

The advantages are nonetheless being explored, however they’re undoubtedly price paying consideration to.
