What to know first
The honest opening on krill oil is that it costs more than the fish oil sitting next to it on the shelf and gives you less of the omega-3s that actually do the work. Most 1,000mg krill softgels deliver only 120 to 165mg of combined EPA and DHA, and the clinical range is 1,000 to 4,000mg of krill oil a day to reach 150 to 600mg of them. So the marketing claim that carries this category, that phospholipid-bound omega-3s absorb better, is true in a narrow sense and misleading in a practical one: absorption is faster acutely, but chronic effects match fish oil once the absolute EPA+DHA dose is equal.
You are paying a premium for a delivery advantage that washes out, on a smaller dose. There are three situations where the premium is genuinely worth it, and they are specific: you get fishy burps from regular fish oil, you want krill's choline without raising the heart-related metabolite TMAO that some choline sources do, or you are specifically working on your cholesterol panel, where the lipid evidence is real.
Outside those, our fish oil guide is the better-value route to the same omega-3s. One hard contraindication before anything else: krill are crustaceans, so a shellfish allergy rules this category out entirely. The full krill oil scorecard carries the evidence grades by claim and the EPA+DHA panel for every product.
The Verdict
Sports Research Superba 2 is our Top Pick at $0.52 per dose, and it is the only product here carrying both IKOS purity certification and MSC sustainable-sourcing certification, which in a category built on a purity claim is the difference worth paying for. Bronson Antarctic is the Best Value at $0.50, and it is now the cheapest credible option because NOW Foods Neptune Krill Oil roughly doubled in price during 2026 to $0.73. Viva Naturals at $0.78 and Kori at $0.67 are reasonable mid-field choices.
At the top of the range, Dr. Mercola at $1.37 is nearly three times the Best Value pick without a corresponding jump in EPA+DHA yield, and Jarrow rose another 24% in August 2026 to $0.90. The larger point stands above all of these: for most people fish oil delivers the same omega-3s for less. Buy krill if fish oil repeats on you, if you want the choline, or if cholesterol is the goal. And skip the category entirely if you are allergic to shellfish.
What you are actually buying per dose
A 1,000mg krill softgel typically carries 120 to 165mg of combined EPA+DHA. The clinical range is 1,000 to 4,000mg of krill oil daily, which is how you reach the 150 to 600mg of EPA+DHA the research actually rests on. The osteoarthritis trials used 4g a day, so a single softgel is well short of what was studied.
Cost per dose across the products we score:
- Bronson Antarctic: $0.50. Our Best Value.
- Sports Research Superba 2: $0.52. Our Top Pick, IKOS and MSC certified.
- Kori: $0.67. NOW Foods: $0.73, after roughly doubling in 2026.
- Viva Naturals: $0.78. Jarrow: $0.90, up another 24% in August 2026.
- Dr. Mercola: $1.37, nearly 3x the Best Value pick.
Note that those are per single dose, not per clinical day. If you are chasing the 4g protocol the joint trials used, multiply accordingly, and at that point the cost gap against fish oil becomes very hard to justify. The scorecard lists each product's EPA+DHA panel so you can compare what you are actually getting rather than what the front label says.
When krill oil is genuinely worth the premium
Fishy burps. This is the most common real reason people switch, and it is a legitimate one. If standard fish oil repeats on you, adherence collapses, and a supplement you stop taking has no benefit at any price. Krill's phospholipid form is generally better tolerated.
Choline without the TMAO question. Krill oil carries choline in phosphatidylcholine form. Some choline sources raise TMAO, a metabolite linked to cardiovascular concern, and krill's form appears not to in the same way. If you want choline and that distinction matters to you, this is a real point of difference.
Cholesterol specifically. The lipid evidence for krill oil is the strongest part of its case and it is genuinely there, which is not something we can say for the joint or PMS claims the category also markets on.
What is NOT on that list is general omega-3 supplementation, which is what most people are buying it for. For that, the same EPA+DHA costs less from fish oil, and the absorption advantage does not close the gap because it is acute rather than chronic. Our fish oil guide covers that route. And to repeat the one hard rule: krill are crustaceans, so a shellfish allergy rules out this entire category regardless of which case applies to you.

What to Look For When Buying
- ✓Read the EPA+DHA panel, not the krill oil milligrams: a 1,000mg softgel typically delivers only 120-165mg of the actual omega-3s
- ✓The clinical range is 1,000-4,000mg krill oil daily, and the osteoarthritis trials used 4g, so a single softgel is rarely the studied dose
- ✓Prefer IKOS or MSC certification, which cover purity and sustainable sourcing respectively
- ✓The absorption advantage over fish oil is acute rather than chronic, so it does not compensate for a smaller EPA+DHA dose
- ✓Skip it entirely with a shellfish allergy, since krill are crustaceans
- ✓Do not buy krill oil for joint pain or PMS: the evidence for both is mixed at best

Krill Oil Supplement with EPA & DHA - 1000mg
Frequently Asked Questions
Is krill oil better than fish oil?
It depends on your priorities. Krill oil's phospholipid-bound omega-3s may be better absorbed per milligram, and it causes less fishy aftertaste. However, concentrated fish oil products deliver significantly more EPA and DHA per serving at a lower cost. For basic omega-3 supplementation at the best price per gram of EPA/DHA, fish oil wins. For tolerability and potentially better absorption, krill oil has advantages.
How much EPA and DHA does krill oil actually provide?
Most 1,000mg krill oil softgels provide only 120-165mg of combined EPA and DHA. This is substantially less than a typical fish oil capsule (300-500mg EPA/DHA per 1,000mg). You may need 2-3 krill oil softgels to match the EPA/DHA content of one concentrated fish oil capsule, though the phospholipid form may partially offset this through better absorption.
Can I take krill oil if I have a shellfish allergy?
This requires extreme caution. Krill are crustaceans, and while the allergenic proteins in shellfish are primarily in the flesh rather than the oil, there is potential for cross-contamination. Most allergists advise against krill oil for individuals with known shellfish allergies. Consult your allergist before use.
What is the astaxanthin in krill oil?
Astaxanthin is a naturally occurring carotenoid antioxidant that gives krill (and salmon, shrimp, and flamingos) their red-pink color. It serves a dual purpose in krill oil supplements: it helps prevent the omega-3s from oxidizing (extending shelf life and freshness) and may provide its own antioxidant benefits. Amounts vary significantly between products, from 17mcg to 1,600mcg per serving.
What does IKOS certification mean for krill oil?
IKOS (International Krill Oil Standards) is a third-party certification program that verifies the purity, potency, and freshness of krill oil products. Products with IKOS certification have been independently tested for heavy metals, oxidation levels, and accurate labeling of EPA/DHA content. It is one of the strongest quality indicators for krill oil.
