You pick an EPA DHA supplement to feel better, not to taste fish for the next three hours.

Here, 9 leading softgels are compared on the specs that decide your experience — EPA and DHA per serving, softgel size, and purity safeguards.

To find the epa dha supplement that fits your routine, focus on the per-serving EPA and DHA totals, the softgel count, and how each brand prevents fishy aftertaste.
Our Picks at a Glance
How To Choose The Best EPA DHA Supplement
Start with the EPA and DHA numbers on the label, not the total fish oil weight. A softgel can say “1000 mg fish oil” but only deliver a fraction of that as the active EPA and DHA you actually absorb.
Check the EPA and DHA per Serving
EPA and DHA are the omega-3 fatty acids that support heart, brain, and joint health. Look for the exact milligrams of each on the supplement facts panel. A serving with 500 mg EPA and 250 mg DHA gives you a 2:1 ratio that many brands aim for.
Look for Purity and Distillation Methods
Quality brands use molecular distillation to strip out heavy metals like mercury and other contaminants. Some go further with third-party testing for oxidation and active potency, which means the oils stay fresh and effective from bottle to bottle.
Consider Softgel Size and Daily Count
A high-potency formula may let you take just one softgel a day, while lower-dose options need two or more. Bigger softgels can be harder to swallow, so balance the daily pill count against the softgel size that feels comfortable for you.

In‑Depth Reviews
1. NOW Foods Ultra Omega-3
Our pick — over 4.5★ from 750+ verified ratings; the strongest balance of quality and price.
The crowd favorite that pairs a 500 mg EPA punch with a coating that kills fishy burps.
You get 500 mg EPA and 250 mg DHA per serving, a 2:1 ratio that owners call the best they have tried. The enteric coating (a protective layer that resists stomach acid) is why buyers report no fishy burps. — one said, “Thanks to the enteric coating, you don’t get those annoying fishy burps.” That coating holds the softgel together until it reaches your intestine, so the oil does not come back up on you.
The 180-count bottle means a two-softgel daily serving lasts you three months. Quality gets the most praise in reviews, with effectiveness close behind — owners say they notice a difference in their joints when they skip a day. The fish gelatin softgel is note if you avoid bovine or porcine gelatin.
Swallowing gets mixed feedback, so the softgel size is the one thing to weigh before you buy. If you struggle with larger pills, you may want to test with water first.
What wins people over
- 500 mg EPA and 250 mg DHA per serving means fewer softgels daily
- Enteric coating stops fishy burps and aftertaste
- Keto-friendly and soy-free formulation
What to weigh first
- Some owners find the softgels hard to swallow
- Quality concerns from a single review about freshness
Reach for this if: you want a high EPA dose with proven burp protection and a trusted, family-owned brand.
Look elsewhere if: you have trouble swallowing larger softgels and prefer a smaller pill.
2. Webber Naturals Ultra Omega 3
A two-per-day formula packing 1800 mg of combined EPA and DHA into each serving.
Each 2850 mg serving of fish oil delivers 1800 mg of omega-3 EPA and DHA combined, which makes this one of the higher-total options on this list. The clear enteric softgel technology is designed to boost absorption and block fishy aftertaste, and owners confirm there is no fishy taste or strong smell.
The value angle is strong — a 120-softgel bottle gives you 60 days at two per day, and the formula is free of dairy, sugar, wheat, gluten, yeast, soy, corn, egg, shellfish, salt, tree nuts, and GMOs. Owners specifically praise this for easing arthritis pain in the thumb, and one notes it is the only brand their picky partner will use.
The honest catch is freshness: “Good value, but they will go rancid before bottle finished unless refrigerated” is a recurring warning in reviews. Plan to store this one in the fridge.
Why it earns its spot
- 1800 mg combined EPA and DHA per serving is a high total
- Clear enteric softgels prevent fishy aftertaste
- Free of the top 14 common allergens and GMOs
The trade-off
- Must be refrigerated to avoid rancidity before the bottle is done
- Swallowability is mixed in reviews
Grab this for: a budget-friendly, high-total omega-3 that stays fresh when chilled.
Think twice if: you cannot commit to refrigerating a supplement every day.
3. Micro Ingredients Omega-3
A lemon-flavored 300-count pouch that makes daily omega-3 easy on the wallet.
This pouch delivers 180 mg EPA and 120 mg DHA per two-softgel serving, sourced from Norwegian deep sea fish. The 300-softgel count is the biggest on this list — a 2.5x gap over the 120-count Webber Naturals bottle, so this lasts far longer for roughly the same money.
Owners praise the easy swallowability and the complete lack of fishy burps, with one noting “My bp is lower and no heart issues” after switching. The sweet lemon flavor masks any fishiness, and the formula is non-GMO with no soy, dairy, or gluten.
The lower EPA and DHA numbers mean you take more softgels to match a high-dose brand — 500 mg EPA would take roughly three servings here versus one NOW softgel. That is the main reason this sits at budget tier despite its huge bottle.
What stands out
- 300 softgels is the best volume-to-price ratio here
- Lemon flavor and small size make swallowing easy
- Purified to remove heavy metals like mercury
The catch
- Only 180 mg EPA per serving, so you need more softgels daily
- Texture gets a rare negative mention
Pick this if: you want the lowest cost per softgel and an easy-to-swallow daily habit.
skip it if: you need a high EPA dose in as few pills as possible.
4. Natural Factors RxOmega-3
Pharmaceutical-grade fish oil with 800 mg EPA, third-party tested for over 800 contaminants.
This is the highest EPA dose on the list at 800 mg per two-softgel serving, with 400 mg DHA alongside it. Every batch is third-party tested by ISURA for over 800 contaminants including pesticides, solvents, and heavy metals — a purity standard that justifies the premium positioning.
Owners mention real lab-verified results, with one seeing HDL rise from 52 to 76 in six months. The enteric-coated softgels have no artificial flavoring, and customers note reduced dry eyes after about a month of daily use. The formula is free of dairy, sugar, wheat, gluten, yeast, soy, egg, shellfish, salt, tree nuts, and GMOs.
The softgels run large, so owners advise taking them after a full meal to avoid any fishy burp. At 120 softgels for a two-per-day routine, this is a 60-day supply from a family-owned company with over 60 years in supplements.
What justifies the price
- 800 mg EPA and 400 mg DHA is the strongest dose here
- ISURA tests every batch for 800+ contaminants
- Enteric-coated to prevent fishy aftertaste
What to expect
- Larger softgels are easier to swallow with water after a meal
- Premium price reflects the higher potency
Choose this for: the highest purity standard and strongest EPA dose in one bottle.
Consider elsewhere if: you prefer a smaller softgel or a lower price per bottle.
5. Nature Made Fish Oil
A pharmacist-recommended staple with 2000 mg fish oil and a 125-day supply.
This is the supplement you already know from pharmacy shelves: United States Pharmacopeia (USP) Verified with 500 mg of combined EPA and DHA per serving. The 250-count bottle is a 125-day supply, which makes it the longest-lasting option here at two softgels daily.
Reviewers point out cholesterol management as the standout benefit, with one saying they have “little to no problem with my cholesterol” after years of use. The formula is gluten-free, dairy-free, with no color added and no artificial flavors. Odor and taste get consistent positive mentions — no fishy smell or taste.
The pill size draws the most negative feedback, with several owners calling the softgels too big. Refrigerating them reduces burps, according to reviewers, which is a workaround worth knowing.
Why it’s a staple
- USP Verified with 50+ years of brand expertise
- 125-day supply from a single 250-count bottle
- No fishy smell, taste, or aftertaste
Know before you buy
- Pill size is the most common complaint
- Refrigeration helps reduce burps
Best for: anyone who trusts pharmacist-recommended brands and wants a long-lasting supply.
Not ideal if: large softgels are a dealbreaker for your swallowing comfort.
6. Sports Research Omega-3
One softgel with 690 mg EPA from wild Alaska Pollock, backed by IFOS 5-Star ratings.
This is the one-a-day answer to high-dose omega-3: a single softgel delivers 1250 mg of fish oil with 690 mg EPA and 260 mg DHA in the triglyceride form your body absorbs best. The 10-step molecular distillation removes fishy aftertaste, burps, and lingering odor — and owners confirm it.
Sourced exclusively from wild-caught Alaska Pollock in the Bering Sea, this is Marine Stewardship Council (MSC) certified sustainable and IFOS 5-Star rated for purity and freshness. Shoppers say reduced morning knee stiffness within three weeks and improved eye comfort as daily-use benefits.
The trade-off is the premium price — buyers report this one “definitely hurts the wallet” compared to multi-softgel options. The softgels are on the larger side, but most owners find them easy to take with no stomach upset.
What makes it premium
- 690 mg EPA and 260 mg DHA in just one daily softgel
- MSC-certified sustainable wild Alaska Pollock source
- IFOS 5-Star rated for freshness and purity
The honest cost
- Premium price per bottle is the top complaint
- Softgels run large but are generally easy to swallow
Reach for it if: you want maximum potency with the convenience of a single daily pill.
Look past it if: budget is your priority and you do not mind multiple softgels.
7. THORNE Prenatal DHA
A DHA-forward formula with 650 mg per serving, built for pregnancy-related nausea.
This flips the usual EPA-to-DHA ratio for pregnancy: 650 mg DHA and 200 mg EPA per serving, which supports baby’s brain and nervous system development. The small gelcaps use rosemary, mint, and mixed tocopherols to reduce fishy burps and digestive symptoms for mothers dealing with pregnancy-related nausea — and owners confirm no nausea at all.
Third-party tested for over 250 contaminants, this is gluten-free, soy-free, and dairy-free with clean ingredients and no fillers. Owners describe it as flavorless and easy to take, even in the first trimester when swallowing anything can be a chore. The brand is trusted by 100+ professional sports teams and is a top clinical recommendation.
The 60-count bottle is a 60-day supply, and owners mention you still need a separate prenatal vitamin for other nutrients. The price draws mixed feedback — some call it well worth it, others find it expensive.
Why it leads for pregnancy
- 650 mg DHA per serving prioritizes baby’s brain development
- Rosemary and mint minimize fishy burps and nausea
- Third-party tested for 250+ contaminants
What to plan for
- You still need a separate prenatal vitamin
- Price is a point of debate among buyers
Choose this if: you are pregnant and want a nausea-friendly, DHA-focused supplement.
Pick something else if: you need a higher EPA dose or want to skip a separate prenatal vitamin.
8. Nordic Naturals Ultimate Omega
The best-selling omega-3 with a lemon taste that genuinely kills fishiness.
This is the #1 selling omega-3 brand in the U.S., and the 1280 mg omega-3 per serving (650 mg EPA and 450 mg DHA) explains why. The triglyceride molecular form — the same form naturally found in fish — is designed for optimal absorption, and the lemon flavor eliminates any fishy aftertaste.
Customers note reduced inflammation, improved joint pain, and no burping at all. The 90-count bottle at two softgels daily is a 45-serving supply. Quality draws over 3,600 mentions in reviews, making it the most-praised aspect by a wide margin.
The value debate is real: some call it worth the cost, others say the price stings. One practical note from buyers — if you need a high dose at two softgels twice daily, the bottle goes fast, making the value case weaker against higher-count options.
What earns the #1 spot
- 650 mg EPA and 450 mg DHA in triglyceride form
- Lemon flavor removes fishy taste and burps
- Non-GMO with purity guaranteed per batch
The value question
- Price is a point of debate in reviews
- Softgels are large but generally easy to swallow
Go with this if: you want a proven, best-selling formula with great taste and absorption.
Budget first? A higher-count bottle from a value brand will cost less per serving.
9. Nordic Naturals Ultimate Omega 2X
The most concentrated Nordic formula at 2150 mg EPA + DHA, plus Vitamin D3.
This is the highest-concentration omega-3 Nordic Naturals makes, delivering 2150 mg of combined EPA and DHA per serving with added Vitamin D3 for calcium absorption and immune support. The lemon taste carries over from the standard formula, and owners confirm no nasty aftertaste or burps.
Reviewers point out lowered triglycerides, improvements in dry eye, and reduced inflammation. The formula is non-GMO, gluten-free, and dairy-free with no artificial colors, flavors, or preservatives. One owner takes it daily for migraine and concussion recovery and notes it leaves no fishy echo.
The 60-count bottle at two softgels daily is a 30-day supply, which makes this the shortest-lasting and priciest option here. That concentrated dose is the point — you get more active omega-3 per softgel than anywhere else on this list.
The potency argument
- 2150 mg EPA + DHA per serving is the highest here
- Vitamin D3 adds calcium absorption and immune support
- Lemon taste with no fishy aftertaste or burps
What to know
- 60-count bottle lasts only 30 days at two softgels daily
- Highest price per bottle on this list
Buy this for: maximum omega-3 concentration with the bonus of Vitamin D3 in one daily habit.
Choose another if: you want a longer-lasting bottle or a lower cost per serving.
Understanding the Specs
EPA and DHA per Serving
EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are the two omega-3s your body relies on most. EPA supports heart and joint health, while DHA is key for brain and eye function. The ratio matters — a 2:1 EPA-to-DHA balance suits general wellness, while pregnancy formulas flip it to favor DHA for baby’s development.
Triglyceride Form
Fish oil naturally stores omega-3s as triglycerides, the form your body absorbs best. Some brands use ethyl ester forms that are cheaper to produce but less bioavailable. When a label says “triglyceride form,” it means the oil is closer to what you would get eating the fish directly.
Enteric Coating and Burpless Formulas
An enteric coating delays the softgel’s breakdown until it reaches the intestine, which stops fish oil from repeating on you. Burpless formulas add lemon flavoring or natural extracts like rosemary and mint to mask any residual fishiness. If you hate fishy burps, this is the spec to prioritize.
Molecular Distillation and Third-Party Testing
Molecular distillation removes heavy metals like mercury, PCBs, and other contaminants from the oil under vacuum and heat. Brands that add third-party testing, like ISURA or IFOS, verify each batch for oxidation, potency, and purity — so the label matches what is actually in the softgel.
