Jarrow Formulas Krill Oil is the bottle to reach for when brand trust matters more to you than topping any single spec sheet. At $30 for 60 softgels (a 30-day supply at 2/day), it ships a phospholipid omega-3 complex from a Los Angeles formulator that's been publishing reference-cited, third-party-tested supplements since 1988. Each 2-softgel serving delivers 250 mg of combined omega-3 (120 mg EPA / 65 mg DHA) bound to phospholipids, plus 240 mcg of astaxanthin — the carotenoid that keeps krill oil from going rancid and gives it a clean, near-zero-burp profile. The honest framing: Jarrow's krill is solid and trustworthy but unremarkable on the axes that separate the field. Its astaxanthin is the lowest of the disclosed picks on our list, the dose and price sit mid-pack, and the listing doesn't headline a sustainability certification. Eight weeks running 2 softgels/day with breakfast, here's the breakdown.

Read the complete Omega-3 guide →Phospholipid-bound EPA + DHA at 250 mg combined omega-3 (120 EPA / 65 DHA) per 2-softgel serving. The phospholipid format earns a small per-mg absorption edge (~10-20% vs triglyceride), but the absolute per-serving dose is a fraction of a concentrated fish-oil capsule's 500-900 mg. Solid for the krill tier, modest in absolute terms — reaching clinical dose would take 8-16 softgels/day.
Jarrow's strongest axis. The company has a long, well-documented third-party-testing reputation and labels the product non-GMO and gluten-free. Antarctic krill naturally carries very low contaminant load — krill sit at the lowest trophic level, eating phytoplankton, so mercury and PCB bioconcentration is near-zero. The QC pedigree is a genuine reason cautious buyers reach for Jarrow.
Antarctic krill oil. The Antarctic krill fishery is managed under CCAMLR with conservative quotas (~1% of estimated biomass annually), and krill is one of the better-managed marine fisheries overall. We score this 7.5 rather than higher because the listing does not headline a specific MSC / Friend of the Sea certification or a branded traceable source (Superba/NKO) — so the sustainability story is good by category default, not verified at the brand level.
$30/month at 250 mg combined omega-3/day (2 softgels) = roughly $2.00 per gram of EPA+DHA — mid-pack for krill, but still about 2-3× the cost of fish-oil picks at $0.40-1.00/g. Reaching the clinical 1-2 g/day window from Jarrow Krill alone would cost well over $100/month. The phospholipid format and astaxanthin don't justify that premium for cost-focused buyers.
Clean phospholipid burp profile with virtually no fishy repeat — the format works as intended. The trade-off: 240 mcg astaxanthin per serving is the lowest of the disclosed picks (vs 1 mg Sports Research, 1.6 mg Viva), so slightly less oxidative buffer on paper. In practice all krill astaxanthin doses sit far below therapeutic levels, so tolerance is excellent but the astaxanthin is a stability feature, not a selling point here.
“Phospholipid omega-3 complex — superior absorption.”
The phospholipid-bound absorption advantage is mechanistically real but practically modest. Ramprasath 2013 and Ulven 2011 measured roughly equivalent or 10-20% higher Omega-3 Index / plasma EPA+DHA from krill vs fish oil at equivalent doses — meaningful but not 'dramatically superior.' Jarrow's complex-form framing is on the right side of the truth, slightly overstated as with all krill marketing.
“Contains naturally occurring astaxanthin.”
The label discloses 240 mcg of astaxanthin per serving — a genuine carotenoid antioxidant that stabilises the oil against oxidation. The figure is real and honestly stated, though it's the lowest of the disclosed picks on our list and well below the 4-12 mg used in dedicated astaxanthin trials. Accurate claim.
“Antarctic krill source.”
Antarctic krill is harvested in the southern-ocean ecosystem with virtually no industrial-pollution exposure; krill sit at the lowest trophic level (eating phytoplankton), so mercury and PCB bioconcentration is near-zero. The Antarctic-source claim is real and represents one of the lowest-contaminant marine omega-3 origins available.
“Non-GMO and gluten-free.”
Both are label claims consistent with Jarrow's documented formulation standards and long third-party-testing track record. Krill oil is inherently free of gluten-containing grains, and the non-GMO designation is a standard, auditable Jarrow claim. Honest and verifiable.
“Supports heart, brain, and joint health.”
All three are real EPA+DHA effects backed by the broader omega-3 literature (Mozaffarian 2008 cardiovascular, Serhan 2014 resolvin-driven anti-inflammatory, Yurko-Mauro 2010 cognition). The framing is accurate in spirit, but at 250 mg combined omega-3 per serving the per-serving dose is low enough that reaching clinical effect requires several servings/day. Standard marketing simplification.
Jarrow Formulas has spent since 1988 building a science-forward, reference-cited identity, and its third-party-testing record is among the more credible in the legacy-supplement tier. That QC pedigree — non-GMO, gluten-free, documented label — is the genuine differentiator here. If you're a cautious buyer who wants a phospholipid-bound krill oil from a name with a long clean track record rather than the highest-spec bottle on the shelf, Jarrow earns the slot. It's a trust play, not a numbers play.
The front of the bottle says 1200 mg, but that's total krill oil across a 2-softgel serving. The supplement-facts panel discloses the number that matters: 250 mg of combined omega-3 (120 EPA / 65 DHA). Only ~25% of krill oil is EPA+DHA, so a single concentrated fish-oil capsule (500-900 mg) carries two to three servings' worth of actives. This isn't a Jarrow flaw — it's true of every krill oil — but it's the core reason krill is a tolerability/astaxanthin play, not a high-dose omega-3 source.
Jarrow discloses 240 mcg of astaxanthin per serving. That's a transparent figure — and lower than Sports Research (1 mg/softgel) or Viva Naturals (1.6 mg/serving). Astaxanthin's job in krill oil is oxidative stability and the near-zero burp profile, both of which Jarrow still delivers fine. But if your specific reason for choosing krill is to bundle in as much astaxanthin as possible, Jarrow is not the bottle to optimise for — Viva Naturals (#5) leads the list on that single axis. Even there, remember 1.6 mg is far below the 4-12 mg standalone-trial dose.
At ~$1.00 per 250 mg serving, Jarrow Krill works out to roughly $2.00 per gram of EPA+DHA. That's middle-of-the-road for the krill tier, but still about 2-3× the $0.40-1.00/g you'd pay for concentrated triglyceride-form fish oil. If you're optimising cost-per-mg of omega-3 — or you need the 1-2 g/day cardiovascular range — fish oil wins decisively. Jarrow's price is fair for what it is; it just can't escape krill's structural cost premium.
Krill are crustaceans, and krill oil — Jarrow's included — contains residual crustacean proteins that can trigger reactions in shellfish-allergic users. Most krill oil is processed to minimise allergenic protein content, but documented allergic reactions are real and well-reported in the literature. Absolute rule: if you have any documented shellfish allergy, do not buy krill oil regardless of brand or processing claims. A vegan algal-oil omega-3 delivers the same EPA+DHA with zero crustacean exposure and is the safe alternative.
Jarrow Formulas Krill Oil is what we recommend to a specific buyer: someone who's decided on the krill format — usually because fish-oil burps drove them to quit — and wants it from a formulator with a long, clean, science-forward reputation rather than the flashiest numbers on the shelf. Jarrow has been publishing reference-cited, third-party-tested supplements since 1988, and its krill complex delivers a respectable 250 mg of phospholipid-bound combined omega-3 per serving, non-GMO and gluten-free, with the clean burp profile krill buyers come for. For the trust-first buyer, it's a perfectly sound choice. What it isn't is a category leader. The astaxanthin (240 mcg) is the lowest of the disclosed picks, the dose and price sit mid-pack at roughly $2.00 per gram of EPA+DHA, and the listing doesn't headline a sustainability certification or a branded traceable source. Anyone who wants a clearer, single-axis reason to buy will find it elsewhere: Sports Research (#1) for more EPA+DHA per softgel, MSC-certified Superba2 krill, more astaxanthin, and a lower price; NOW Neptune NKO (#3) for the most clinically-studied branded oil. And the universal krill caveats apply — if you're optimising cost-per-mg of omega-3, fish oil is ~2-3× cheaper per gram, and if you have any shellfish allergy, skip krill entirely and use a vegan algal-oil omega-3.

The basis for Jarrow's phospholipid-complex claim being scored 'partial.'
Krill oil produced metabolic effects and plasma EPA+DHA increases comparable to fish oil despite a lower absolute EPA+DHA dose — direct evidence for the per-milligram phospholipid edge, while underscoring how little EPA+DHA krill actually delivers (Jarrow's 250 mg/serving included).
Krill oil raised plasma EPA+DHA to a degree comparable to menhaden (fish) oil at a similar omega-3 dose, confirming bioequivalence of the phospholipid form — the basis for treating Jarrow's krill complex as a legitimate but expensive omega-3 source.
Comprehensive review of krill composition documenting the phospholipid-bound EPA+DHA structure and the naturally occurring astaxanthin that gives krill oil its oxidative stability — the mechanistic basis for Jarrow's clean, rancidity-resistant burp profile despite its modest 240 mcg astaxanthin disclosure.
Established the Omega-3 Index (RBC EPA+DHA %) as a cardiac-risk marker, with an Index above 8% tied to the lowest risk of coronary-heart-disease death — the endpoint that justifies tracking actives intake regardless of source, and the reason Jarrow's 250 mg/serving needs multiple servings to move the needle.
