Best Krill Oil 2026: Ranked by EPA+DHA per Serving & Astaxanthin
Informational summary — not medical advice. This page ranks product value at a given disclosed dose; on whether krill oil works, see the hub and the fish-oil comparison. Krill is a crustacean — a real shellfish-allergy risk. This statement has not been evaluated by the FDA. This product is not intended to diagnose, treat, cure, or prevent any disease.
Only 3 of the 6 krill oil products checked here disclose EPA+DHA mg — the other 3 (NOW Foods, Schiff MegaRed, BulkSupplements.com) don't, anywhere reachable. That's ranked as a real penalty, not filled in with a guess. Among the disclosed group, the cheapest per 250mg EPA+DHA is Sports Research Antarctic Krill Oil, 1000mg (Superba2) ($0.54/250mg), and the densest is Sports Research Antarctic Krill Oil, 1000mg (Superba2) (240mg EPA+DHA/gram). Viva Naturals is the only one disclosing astaxanthin content (1.6mg astaxanthin/serving (disclosed)).

The one-line takeaway Half the products checked here (3 of 6) don't disclose the number that actually matters — EPA+DHA mg — so a real cost-per-omega-3 comparison is only possible for 3 of them. Among those, the cheapest per 250mg EPA+DHA isn't the cheapest bottle — it's the densest one. Buy by disclosed mg, never by softgel weight or total "krill oil mg."
Every product compared: disclosed EPA+DHA & cost
Sorted disclosed products first (cheapest cost per 250mg EPA+DHA), undisclosed products after. Read the EPA+DHA/serving and Density columns before the price — they tell you what you're actually buying. Full data is a public CC BY JSON file.

Prices are live Amazon buy-box figures, verified 2026-07-19; they move. Cost per 250mg EPA+DHA = (price ÷ (servings × disclosed EPA+DHA mg)) × 250, using Kori's own 250mg serving as the reference dose. Density = disclosed EPA+DHA mg ÷ (krill oil mg per serving ÷ 1000).
Third-party testing and the IKOS standard
The International Krill Oil Standard (IKOS) and other third-party purity/freshness certifications are a real thing to look for in this category — krill oil is more prone to oxidation than fish oil, and a certification is one honest signal a brand tests for it. Reported plainly: none of the six products in this comparison state an IKOS or other third-party certification on their current retail listing or manufacturer page that we could verify for this pack, so certification isn't a usable ranking axis here yet. That's a real gap in this category, not something to paper over with an assumed "probably tested" credit — if a certification matters to you, verify it directly on the product's current packaging or COA before buying, since claims can change between our price-verification passes.
Why NOW Foods, MegaRed, and BulkSupplements aren't ranked by cost per mg
These three products are real, buyable krill oil supplements with live prices, and they're included in the table above so you can compare sticker cost — but none of them can be ranked by cost per mg of actual omega-3, for one honest reason:
- No disclosed EPA+DHA breakdown. Each lists a total krill oil mg on the front of the label (500mg, 750mg, and 1000mg respectively), but none states how much of that is EPA+DHA — not on the label, not on the brand's own site, and not on major retailer listings checked for this comparison. BulkSupplements.com is the starkest example: even the manufacturer's own product page, which lists total krill oil mg and other ingredients, skips the EPA/DHA split entirely.
This isn't proof these products contain less omega-3 than the disclosed ones — it's proof you can't verify how much they contain. Treat the missing number as a real strike against buying confidently, not a technicality.
Frequently asked questions
What is the best krill oil supplement?
Of 6 products checked, only 3 disclose EPA+DHA mg. Cheapest per 250mg among those: Sports Research Antarctic Krill Oil, 1000mg (Superba2) (~$0.54/250mg). The other 3 don't disclose EPA+DHA at all — a real ranking penalty.
Why do 3 products not disclose EPA+DHA?
Unknown — they simply don't state it anywhere reachable, including BulkSupplements' own manufacturer page. No number is guessed or estimated to fill the gap; they're ranked below the disclosed group on that basis.
Why does the cheapest sticker price rank lower?
Cost per 250mg disclosed EPA+DHA — not cost per bottle — is the honest comparison. The highest-density product here is cheapest per 250mg despite not having the lowest sticker price.
Which krill oil discloses astaxanthin content?
Only Viva Naturals (1.6mg astaxanthin/serving (disclosed)). Real but small; not a reason by itself to accept lower EPA+DHA density.
