If you've started comparing vegan omega-3 supplements, you've probably noticed that every label leads with DHA, most add EPA — and almost none mention DPA. That's not because DPA doesn't matter. It's because DPA is hard to source from plants, so most brands simply leave it out and hope you don't ask.
This guide explains what DPA actually does, why so few vegan formulas include it, and compares the top algae-based omega-3 supplements that contain DPA — ranked on completeness of the omega-3 profile, dosage, capsule quality, and price per day.
In a hurry? Quick answer: Among algae omega-3s that include DPA, Tahiro Algae Omega 3 is the only one in our comparison that delivers all three long-chain omega-3s with a meaningful EPA dose — 300mg DHA + 150mg EPA + 30mg DPA per serving — in a carrageenan-free softgel for $22.95/month. The runners-up each omit or underdose at least one of the three.
What Is DPA — and Why Is It Called the "Forgotten Omega-3"?
There are three long-chain omega-3 fatty acids that matter for human health:
-
DHA (docosahexaenoic acid) — the structural omega-3. It makes up a significant portion of brain and retinal tissue and is the headline ingredient in every omega-3 product.
-
EPA (eicosapentaenoic acid) — the anti-inflammatory omega-3, most studied for cardiovascular and mood support.
-
DPA (docosapentaenoic acid) — the intermediate omega-3, and the one most supplements skip.
DPA sits metabolically between EPA and DHA. Research suggests it functions as a reservoir: your body can convert DPA into either EPA or DHA depending on what it needs at the moment. DPA has also been studied for its own roles in vascular health and supporting healthy blood vessel function, and it appears to help the body retain omega-3 stores more efficiently — one reason DPA-containing formulas are described as improving how long your omega-3s "last" in tissue.
Here's the catch: DPA barely exists in the typical food supply. The richest natural sources are seal oil and certain fatty fish — neither of which helps if you're plant-based. Flax, chia, and walnuts contain only ALA, which converts to long-chain omega-3s at rates of roughly 5–15%. The only practical vegan source of preformed DPA is algal oil from specific algae strains — and growing those strains costs more, which is why most brands quietly leave DPA off the label.
Bottom line: if a vegan omega-3 includes DPA, it signals the brand chose a more complete (and more expensive) algae oil profile rather than the cheapest available DHA concentrate.

How We Compared These Supplements
Every product on this list is vegan, algae-based, and contains DPA — that was the entry requirement, and it eliminated the vast majority of the market. From there we ranked on four factors:
-
Completeness: does it deliver all three omega-3s (DHA + EPA + DPA), or only two?
-
Dosage: total long-chain omega-3s per serving, with attention to EPA (the one most often missing)
-
Capsule quality: carrageenan-free formulas scored higher
-
Value: cost per day at standard serving
All ingredient amounts below were verified against current manufacturer labels and listings (June 2026).
1. Tahiro Algae Omega 3 — Best Overall (Complete DHA + EPA + DPA)
Per serving (2 softgels, 1,000mg algal oil): 300mg DHA · 150mg EPA · 30mg DPA Capsule: tapioca-based, carrageenan-free Supply: 60 softgels / 30 days — $22.95 with free US shipping
Tahiro's formula is the reason this category deserves its own guide: it's the only product in our comparison that delivers a complete trio with a substantial EPA dose. That matters because EPA is the omega-3 most associated with inflammatory balance and cardiovascular support — and as you'll see below, the other DPA-containing vegan formulas either skip EPA entirely or include it at half this level.
The 480mg of combined long-chain omega-3s per serving comes from a single Schizochytrium sp. algae source, in softgels that use tapioca starch instead of carrageenan. No fish anywhere in the supply chain means no mercury or PCB exposure risk and no fishy aftertaste.
At $22.95 for a month's supply (about $0.77/day), it's also the most affordable complete-trio option we found — most premium vegan omega-3s run $30–45/month for two omega-3s, not three.
Pros:
- Only formula here with all three omega-3s at meaningful doses
- Highest EPA in the comparison (150mg)
- Carrageenan-free tapioca softgels
- Lowest cost per day in our lineup
- Free US shipping; subscription saves 15% on the first order
Cons:
- DPA dose (30mg) is solid but not the highest on this list
- Available direct, on Amazon, and Walmart — but the subscription discount is direct-only

2. New Chapter Vegan Omega-3 Complex — Best One-a-Day Trio
Per softgel (835mg algal oil): 250mg DHA · 125mg EPA · 25mg DPA Capsule: modified tapioca starch (carrageenan-free) Supply: 30 softgels / 30 days
New Chapter deserves real credit: it's the other brand that delivers the full DHA + EPA + DPA trio, and it does so in a single daily softgel — convenient if you dislike taking two capsules. The algae is fermented and grown in the USA, and the capsule is also tapioca-based.
The trade-off is dose: at 400mg total long-chain omega-3s, every number is a step below Tahiro's serving (250 vs 300 DHA, 125 vs 150 EPA, 25 vs 30 DPA), and the per-day cost is typically higher. A strong choice if one-capsule convenience is your priority.
Pros: complete trio; one softgel per day; carrageenan-free; US-grown algae Cons: lower dose across all three omega-3s; usually pricier per day
3. Freshfield Vegan Omega 3 DHA + DPA — Best Budget DHA/DPA (No EPA)
Per capsule: 225mg DHA · 35mg DPA — no EPA listed Capsule: carrageenan-free Supply: 1–2 capsules daily.
Freshfield is one of the most-reviewed plant-based omega-3s online, and the brand's sustainability story is genuinely impressive: third-party tested batches, hexane-free enzymatic extraction, carbon-neutral and plastic-negative certification, even a compostable plant-based bottle. Its DPA content (35mg) is slightly higher than Tahiro's.
The significant gap: there is no EPA on the label. Freshfield's own marketing leans on DHA + DPA, with DPA positioned as helping the body store omega-3s. If EPA's inflammatory and cardiovascular benefits are part of why you're supplementing — and for most people they are — this formula leaves a hole that you'd need to fill elsewhere.
Pros: strong sustainability credentials; third-party tested; highest DPA per capsule here; flexible 1–2 capsule dosing Cons: no EPA — an incomplete profile despite the DPA
4. Micro Ingredients Vegan Omega 3 — Highest DHA + DPA Dose (No EPA)
Per serving: 500mg DHA · 100mg DPA (plus flaxseed ALA) — no EPA listed Supply: 240 softgels, lemon flavored.
If raw DHA and DPA numbers are your only criteria, Micro Ingredients delivers the biggest doses on this list, in a carrageenan-free, lemon-flavored softgel, at a bulk-friendly count. The added flaxseed contributes ALA, though remember the 5–15% conversion limitation — ALA is a bonus, not a substitute for preformed EPA.
Like Freshfield, the formula lists no EPA. It's a high-dose DHA/DPA product rather than a complete omega-3, best suited to someone who specifically wants to push DHA intake.
Pros: highest DHA (500mg) and DPA (100mg) per serving; large bottle; lemon flavor masks any oil taste Cons: no EPA; ALA add-on has limited conversion value

The pattern is clear: only two products deliver all three omega-3s, and only one does it with 150mg of EPA at an entry-level price. That's why Tahiro takes the top spot — not on any single number, but on being the formula with no missing piece.
Who Should Prioritize DPA in Their Omega-3?
-
Vegans and vegetarians — you get zero preformed DPA from diet; an algae formula with DPA is the only practical source
-
Anyone switching from fish oil — quality fish oils naturally contain trace DPA; a DHA-only algae product is a downgrade in profile, while a trio formula is a like-for-like (or better) swap
-
People focused on long-term brain and heart maintenance — DPA's reservoir role supports steady tissue omega-3 levels between doses
-
Pregnant women (with physician guidance) — DHA needs rise in pregnancy, and contaminant-free algae sources avoid the concerns attached to some fish products
If brain health is your primary goal, omega-3s pair naturally with omega-5 (punicic acid) — they work on different mechanisms: omega-3s are structural, omega-5 targets oxidative stress. We cover the distinction in Omega-5 vs Omega-3, and our Best Omega 5 Supplements in 2026 guide covers that category in depth.
