Antarctic Krill Oil · Euphausia superba · Neptune Krill Oil
Krill Oil is extracted from Antarctic krill (Euphausia superba) - small shrimp-like crustaceans that form one of the largest biomass species on Earth. Krill oil contains omega-3 fatty acids (EPA + DHA) attached to phospholipids (mainly phosphatidylcholine) rather than triglycerides as in fish oil. This phospholipid structure is theorized to provide better bioavailability and tissue distribution, and is often cited by manufacturers as making krill oil 'more potent than fish oil.' Krill oil also naturally contains astaxanthin (the red pigment that gives krill its color), choline, and trace amounts of vitamins A and E.
Starting dose. 1g — 2 softgels typically
Take with a meal containing fat (improves absorption). 1-3g/day for general support; higher (3-4g/day) for therapeutic cardiovascular use. Look for MSC certified, third-party tested products. Krill oil typically doesn't cause fish burps (a common complaint with fish oil).
Start here. Every protocol below is ordered lowest-first. Begin at the smallest effective dose, hold about a week to assess tolerance, and step up only if needed.
Krill oil's primary mechanism is delivery of omega-3 fatty acids (EPA and DHA) bound to phospholipids - particularly phosphatidylcholine. The phospholipid-bound omega-3s are theorized to integrate more efficiently into cell membranes (especially brain and cardiovascular tissues) compared to triglyceride-bound omega-3s in fish oil. EPA and DHA produce their effects through multiple mechanisms: incorporation into membrane phospholipids (improving fluidity and receptor function), production of anti-inflammatory eicosanoids (resolvins, protectins, maresins), modulation of inflammatory gene expression (NF-kB inhibition), and effects on lipid metabolism (PPAR-alpha activation reducing triglyceride synthesis).
The astaxanthin component (a powerful carotenoid antioxidant) provides additional benefits beyond omega-3 content. Astaxanthin crosses the blood-brain barrier and blood-retinal barrier, providing antioxidant protection in CNS and ocular tissues. It also has anti-inflammatory effects through different pathways than omega-3s, and protects mitochondrial membranes. The astaxanthin content (~150mcg/gram krill oil) contributes to krill oil's joint health and skin protection profiles.
The phosphatidylcholine component provides choline (~30-50mg/gram krill oil), which supports acetylcholine synthesis, phosphatidylcholine biosynthesis for neuronal membranes, and methylation cycle (TMG/betaine formation). For users not getting adequate choline through diet (eggs, organ meats), krill oil's choline content provides supplementary support. The combined nutrients (omega-3 + astaxanthin + choline) make krill oil's effects somewhat broader than pure omega-3 supplementation.

Each reference below was re-fetched from its PubMed record, and the quoted sentence was confirmed to appear in that abstract and to support the claim it sits under. Follow any of them to read the source.

Evidence scope. This entry supports only the exact statement quoted from the live abstract; it does not independently verify OnePin's displayed dose, route, frequency, formulation, population, or broader mechanism.
Claims we could not support
No abstract we checked supports these for this molecule at this route. That is not the same as saying they are false — it marks where the evidence is missing.
Dose/route: 1g (2 softgels typically); Oral; Daily. No checked live PubMed abstract verified this exact displayed dose, route, and frequency for the same molecule/formulation and relevant population.
Primary safety claim: Less fishy burps than fish oil (a key user-preference advantage). No checked live PubMed abstract directly verified this source-JSON safety claim at the displayed formulation, route, and regimen.
Two different questions: what is documented about running these together, and what is documented about drawing them into the same syringe. A good pharmacological partner can still have to be pinned separately.
Check any specific pair in the Stack & Interaction Checker, which answers both questions separately. Absence of a documented conflict is not evidence of safety.
EPA/DHA: ~37-90 hours (cellular incorporation); astaxanthin: ~16 hours
Oral
Days to weeks (cellular incorporation)
Higher than fish oil per matched dose (10-50% improvement). Phospholipid form integrates into cell membranes more efficiently.
Acute anti-inflammatory effects within hours; chronic membrane incorporation builds over weeks to months.
Cellular incorporation, eicosanoid production, eventual oxidation. Astaxanthin metabolized via cytochromes.
Storage. Store in original bottle in a cool, dry place. Refrigeration extends shelf life and maintains potency. Krill oil capsules are sensitive to oxidation - keep tightly sealed. Shelf-stable for 18-24 months in original packaging.
Classified as a dietary supplement in the US. Available widely over the counter. Multiple commercial brands - look for MSC certified (Marine Stewardship Council) for sustainability assurance and third-party testing for purity.
