DPA is the quiet third member of the omega-3 family — most shoppers know EPA and DHA, yet DPA is the one many top-rated blends quietly leave out. You feel it in the dosage: a true DPA supplement carries a real amount on the label, not a token sprinkle. This guide compares 9 fish- and algae-based options, looking at DPA strength, DHA pairing, and the everyday reality of capsules that don’t repeat on you.
I’m Mohammad Maruf — the founder and writer behind Gardening Beyond. This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
Find the right dpa supplement for your budget and diet by comparing DPA milligram counts, capsule sizes, and the cleanest tested formulas side by side.
Our Picks at a Glance
How To Choose The Best DPA Supplement
DPA, or docosapentaenoic acid, is a long-chain omega-3 that your body can use directly or convert into EPA and DHA as needed. Because it is not always listed on fish oil labels, the first thing to check is the actual milligram count per serving. If DPA is absent or unlisted, you are likely buying plain EPA and DHA rather than a true DPA supplement.
Check the DPA milligram dose, not just the omega-3 total
Many premium fish oils announce a big total omega-3 number like 2000mg, but DPA can sit at a tiny fraction of that. Look for the specific “DPA 50mg” or “DPA 100mg” line in the supplement facts panel. A higher DPA count matters most if you are choosing DPA deliberately for its role in supporting EPA and DHA tissue levels and healthy cell function.
Match the source to your diet
Fish-sourced DPA from wild-caught tuna or anchovy suits most people, while algae-sourced DPA gives vegans and vegetarians a fish-free route to the same fatty acid. Algae oil also tends to sidestep the fishy aftertaste that bothers many owners of standard fish oil pills. Your dietary preference should narrow the field before you compare capsule sizes.
Gauge the absorption form and your tolerance
Re-esterified triglyceride (rTG) is a form of omega-3 that is more easily absorbed by your body than the standard ethyl ester found in cheaper oils. If fishy burps have ruined past attempts, look for a burpless formula or a lemon- or orange-flavored softgel. Swallowability is a real factor — some concentrated DHA capsules run large, and easy-swallow reports vary by brand.

In-Depth Reviews
1. Viva Naturals Omega 3 Fish Oil
Our pick — over 4.5★ from 14,000+ verified ratings; the strongest balance of quality and price.
The triple-strength fish oil that wins over 14,000 owners with clean, burp-free daily dosing.
You get more from each softgel with this crowd-favorite DPA and omega-3 pick, backed by 4.7 stars from more than 14,000 ratings. It delivers high-potency 2500mg fish oil per serving in a re-esterified triglyceride (rTG) form, which your body absorbs more easily than standard ethyl ester oils, so you retain more of the nutrients instead of passing them through.
Owners keep coming back because it skips the fishy aftertaste, burping, and heartburn that plague cheaper oils. Reviews lean hard on quality as the most-praised aspect — over 1,200 buyers single out the purity — and the taste earns the second-most praise at 552 mentions. Buyers report, “I have been taking this triple-strength fish oil supplement for a few weeks, and the quality is outstanding,” which sums up the general mood.
The formula is IFOS Certified, Labdoor Quality Certified, and Labdoor Sport Certified, so third-party labs verify purity and potency before the bottle reaches you. Owners mention joint and inflammation support, and the formula is gluten-free, Non-GMO, and pescatarian-friendly. The only mixed note is odor — a minority find the bottle itself smells fishy even if the capsules don’t taste that way.
What wins people over
- High-potency 2500mg serving in an easy-to-absorb triglyceride form
- Triple-certified quality from IFOS and Labdoor, so purity is verified
- No fishy aftertaste, burping, or heartburn for most daily users
The trade-offs
- Some owners find the capsules themselves carry a fishy odor
- Pescatarian-friendly rather than fully vegan, so plant-based buyers should look elsewhere
Who it suits: Anyone wanting a high-potency, third-party-tested fish oil that most people can take without fishy burps.
Reality check: Vegans need to skip this one and move down to the algae options where the DPA lives.
2. Freshfield Omega 3 Algae DHA
The vegan algae softgel that finally hits a real 500mg DHA and 50mg DPA in just two capsules.
If you are tracking the actually-quantified DPA numbers, this is the bottle that shows its work: 500mg of DHA and 50mg of DPA per capsule, derived entirely from algae oil. Customers note, “The nutritionists I read say we should take 2 capsules a day,” and this formula is engineered around that exact advice — the correct dose lands in two softgels, not a handful.
Being algae-based means it skips the fish entirely, which matters for vegetarians and for anyone who cannot stand the taste of fish. The switch also solves the classic fish-oil burp problem — reviewers describe trading nasty fishy-flavored burps for these veggie-based capsules, though a few still detect a slight fish-like flavor. The eco angle is real too, with carrageenan-free capsules and a compostable bio-plastic bottle.
At 2.4 ounces packaged, this is the lightest bottle in this lineup — the Viva Naturals jar above runs 4.94 ounces, a 2.1x gap that mostly reflects the smaller, more concentrated pill count. Every batch is third-party tested and made in North America to pharmaceutical standards, which is reassuring at this budget-friendly price point.
Why it earns its place: You get a clearly-labeled DPA dose, a real DHA punch, and a vegan source that avoids the burp problem — all at a price that undercuts most competitors.
The honest caveat: Not every palate finds it flavor-free, and the eco packaging may vary by country.
3. Garden of Life Dr. Formulated DHA 1,000mg
A single 1000mg DHA softgel a day, designed by a doctor for high-concentration brain support.
This one goes big on DHA concentration — a full 1g (1000mg) of DHA per softgel, with DPA alongside it in triglyceride form. The name “Dr. Formulated” comes from David Perlmutter, MD, and the oil is sustainably sourced from PureSeaOmega3 Tuna for traceable purity. Reviewers point out mental clarity benefits and describe feeling “mellow” after taking it.
It is a once-daily, citrus-flavored softgel, which removes the whole mental load of remembering multiple pills. Reviewers repeatedly note no fishy aftertaste, no heartburn, and no fishy burps — the three taboos of fish oil — while the Marine Stewardship Council certification backs the sustainability claim. The formula also includes SPMs, specialized pro-resolving mediators that support a healthy inflammatory response.
The catch is that this formula is DHA-heavy and does not list an EPA amount, so it is tune for brain and eye support rather than an even EPA-to-DHA split. One reviewer who tracks such things suggests 1 capsule with a meal roughly 4 times a week rather than daily, which could stretch your 30-softgel container much further. The package is compact at 2.38 x 2.38 x 4.24 inches and 2.08 ounces.
Reach for this if: You want a single, small-ish softgel packing a heavyweight DHA dose without fishy side effects.
Look elsewhere if: You need a balanced EPA profile alongside your DHA — the label here does not list EPA.
4. TAHIRO Vegan Omega-3 Softgels
A small, swallow-friendly vegan softgel that puts 30mg DPA, EPA, and 300mg DHA into one balanced serving.
TAHIRO pairs a modest 30mg of DPA with EPA (also 30mg) and 300mg of DHA per serving, creating a nutrient-rich mix aimed at brain clarity and physical vitality. Because it is plant-based algae oil, there is zero fishy taste or smell, and the softgels are genuinely small — a running theme in owner feedback. The taste is the single most-discussed positive, with 52 buyers calling it out, and quality follows close behind at 46 mentions.
The algae oil is sourced from acceptable and renewable sources, and the brand is a Plastic Negative company with a scholarship program funded by each sale. Vegan reviewers have switched from fish-oil brands that tasted rancid or inedible to these, describing them as fresh and clean. The formula is also non-GMO and gluten-free, and serves as a proper alternative for anyone with a fish allergy or dietary restriction.
There is a real difference from the Freshfield bottle above: TAHIRO serves 300mg DHA while Freshfield carries 500mg per capsule, so you take more softgels here for a similar total. But this brand’s oil freshness gets repeated praise, which matters when the alternative is a rancid-tasting bottle. Odor reviews are split, with some finding it pleasant and a minority reporting a bad smell.
Why buyers stay loyal: Consistent freshness, easy swallowing, and a genuinely vegan DPA and DHA source that does not taste like fish.
Who should pass: Anyone who wants the highest DHA-per-pill count — you will need more capsules here than with the 500mg bottles.
5. Micro Ingredients Vegan Omega 3 Algae Oil
The 240-count pouch that stacks 100mg DPA and 500mg DHA with a pleasant lemon finish and no fishy burps.
You get the highest clearly-stated DPA count in this list: 100mg of DPA per 3-softgel serving, paired with 500mg of DHA, 80mg of flaxseed oil, and 40mg of ALA (a plant-based omega-3). The 240 veggie softgels work out to roughly 80 servings, so it is among the most economical ways to get a serious DPA dose. Buyers rave most about the sweet lemon flavor, which leads the positive aspect counts.
Being algae-based, it is fish-free and carrageenan-free, and the formula is made without soy, dairy, gluten, preservatives, colors, or tree nuts. Owners consistently report no fishy burps, no aftertaste, and easy swallowing, even on a nearly empty stomach — the lemon masks any oil taste.
One reviewer warns the softgels are strong and potent, dissolving in the mouth with a powerful lemon taste, and advises not taking more than one at a time. Another received a single melted pill during shipment, which left an oily residue — an occasional shipping hiccup rather than a pattern. Digestibility gets mixed feedback in the review data, so if you have a sensitive stomach, start slow.
What stands out
- Highest stated DPA here at 100mg per serving, alongside 500mg DHA
- 240 softgels stretch to roughly 80 servings, great long-term value
- Lemon flavor wins the top praise, eliminating fishy taste and burps
What to know
- Three-capsule serving is more pills than once-daily rivals
- Potency is high — take one at a time and mind the lemon intensity
Best for: Plant-based buyers who want a specifically-stated 100mg DPA and do not mind a three-pill daily routine.
Think twice if: You prefer a single daily capsule — the 2- or 1-pill options above fit that better.
6. Naturalis Ultra rTG Omega 3 Fish Oil
A wild New Zealand tuna oil boosted with astaxanthin that claims 3.5x higher cell absorption than standard forms.
This premium fish oil leans hard into absorption science: it uses re-formed triglyceride (rTG), the most absorbable omega-3 form, which the maker claims raises omega-3 levels in cells 3.5x higher than standard triglyceride. The oil comes from a single source — wild New Zealand tuna — and carries both Marine Stewardship Council certification and IFOS 5-star rating for traceable purity.
There is a caveat with the burp profile. While many users report no aftertaste, a minority say it causes burping because it lacks an enteric coating (a special layer that helps the capsule survive the stomach). Freezing the softgels helps for that group. It is pescatarian-friendly, non-GMO, hexane-free, and gluten-free, holding up well against the Viva Naturals bottle above on purity claims — though it trails on overall review volume.
Why it sits in the premium tier: MSC-certified single-source tuna plus the rTG form and antioxidant protection for a fresher, higher-absorption oil.
The honest caveat: The no-burp guarantee is not universal — a minority need to freeze the softgels to avoid burping.
7. Oceanblue Professional Omega-3 2100 with CoQ10
A triple-strength fish oil that folds 150mg of CoQ10 into every serving for heart and energy support in one bottle.
This is the combination play for heart support: 1g EPA and 650mg DHA per serving, plus 150mg of CoQ10 (a molecule that supports cellular energy production). The maker claims the formula is 3x more potent than standard retail fish oil and 85% pure, and it includes DPA—the “missing link”—for comprehensive heart support. The whole thing carries Friend of the Sea sustainability certification.
The orange-flavored softgels use proprietary “burpless” technology, and quality leads the positive aspects while effectiveness follows. Shoppers say real joint benefits — one takes it daily with collagen and describes freedom of movement, while another confirms no fishy taste at all. The CoQ10 addition simplifies a routine that might otherwise require a second bottle, which is the main reason someone would pick this over the Viva Naturals above.
Not everything is smooth: the flavor feedback splits, with some finding it clean and a minority calling it horrible, and the burp-free promise does not hold for every user. The serving also runs to more capsules than some rivals, which one owner flags as a lot to swallow daily. It is non-GMO, gluten-free, and major allergen-free, so it suits most diets.
Who it beats: Anyone juggling a separate CoQ10 pill and an omega-3 bottle — this merges both into one orange-flavored routine.
Who it does not fit: Capsule-averse users, since this formula needs multiple softgels and the flavor is not universally loved.
8. Aqua Biome by Enzymedica Maximum Strength
A 2000mg fish oil engineered for your gut microbiome, with targeted delivery to aid absorption where it matters.
Aqua Biome goes a different direction: this fish oil is designed to help your gut microbiome flourish, using targeted delivery to support omega-3 absorption in the gut rather than just the brain. The maximum-strength formula delivers 2000mg of essential fatty acids per serving and names DPA as a key inclusion—something “most fish oils leave out,” per the maker—because your body can use DPA directly or convert it into EPA or DHA as needed.
The formula keeps things clean: purified fish oil, a lemon hint, and easy-to-swallow softgels with no fishy aftertaste or burps. Quality is the most-praised aspect by far, and taste follows. Owners describe “the very best I have found by far” with no fishy burps all day, plus peripheral benefits like thicker hair and stronger nails. The gut angle is what separates this from the Viva Naturals pick — if your goal is digestive and microbiome support over pure brain focus, this is the targeted choice.
The softgels are not small, and one former user admits they now struggle to swallow them, suggesting you may need to cut one open and mix it into food. The price sits at the premium end of this list, yet the 120-softgel count delivers a solid 2-per-day supply. It earns its label as a source of DPA, EPA, and DHA in one clean bottle.
Best for: Buyers who want omega-3 support aimed at gut health and microbiome diversity, not just heart and brain.
Expect a trade-off: The capsules run large — if you have trouble with bigger pills, this one may frustrate you.
9. Microbiome Labs Omega Ultra SPM
The gut-specific fish oil that flips the ratio toward higher EPA than DHA, built for immune and gut barrier support.
This is the specialist’s pick: a full-spectrum fish oil scientifically framed around gut health, with a higher EPA content than DHA—the inverse of most brain-focused blends. The maker cites a Journal of Scientific Reports study showing omega-3s increase microbial diversity, supporting beneficial bacteria like Bifidobacterium and Akkermansia muciniphila, plus intestinal alkaline phosphatase (IAP) production that balances gut microbiota.
DPA is highlighted as the “forgotten fatty acid,” uniquely supporting DHA and EPA tissue status while also supporting a healthy gut. The formula is suitable for ages 8 and up, taken twice daily with a meal, which broadens its reach beyond typical adult-only supplements. Buyers report no fishy aftertaste, no stomach upset, and clean ingredients, with some noting a visible mood improvement when they keep up their daily dose.
This is the most expensive bottle in this lineup, and its 60-softgel count means a twice-daily serving will empty it in a month. The pills are also described as large and potentially hard to swallow. But for anyone specifically seeking a gut-targeted EPA-DHA-DPA ratio rather than a general-purpose oil, this is the precisely-formulated answer — there is no other bottle here with this gut-first design philosophy.
Why specialists choose it: The higher-EPA-than-DHA ratio is deliberately built for gut and immune barrier support, with SPMs added for inflammation response.
The price reality: You pay a premium for the targeted formula, and the large capsules plus 60-count supply mean frequent reordering.
Understanding the Specs
DPA Milligrams per Serving
DPA is the “forgotten fatty acid” because so many labels omit it. A genuine DPA supplement shows its milligram count clearly, like 50mg or 100mg per serving. More DPA matters if you want its unique role in supporting EPA and DHA tissue levels and healthy cell function — not just the total omega-3 headline number.
EPA and DHA Balance
The ratio of EPA to DHA changes what the oil is tune for. Higher DHA favors brain and eye support, while higher EPA leans toward inflammation and gut health. The Microbiome Labs pick flips toward EPA for gut barrier support, while Garden of Life goes DHA-heavy — pick the balance that matches your goal.
rTG and Absorption Forms
Re-esterified triglyceride (rTG) is the form your body absorbs most easily. It costs more to produce than standard ethyl ester, which is why budget oils skip it. If absorption matters to you, look for “triglyceride form” on the label — the Viva Naturals and Naturalis picks both use it.
Third-Party Certifications
IFOS (International Fish Oil Standards) and Marine Stewardship Council (MSC) certifications verify purity, potency, and sustainable sourcing. These are the markers of a trustworthy oil, tested by an outside lab rather than the brand itself. Weight them heavily when comparing brands at similar price points.
