Krill Oil (Phospholipid Omega-3)

Evidence

Moderate
Evidence: 3 of 5 (Moderate)

What the evidence says

Oil from Antarctic krill (Euphausia superba) delivering EPA and DHA in phospholipid form plus natural astaxanthin. Network meta-analyses (26 studies) show higher omega-3 bioavailability than triglyceride/ethyl-ester fish oil — phospholipid-bound omega-3s integrate into cell membranes more efficiently.

Network meta-analyses show higher omega-3 bioavailability than fish oil; small/moderate RCTs for triglycerides, knee OA, skin, and PMS

About Krill Oil (Phospholipid Omega-3)

Oil from Antarctic krill (Euphausia superba) delivering EPA and DHA in phospholipid form plus natural astaxanthin. Network meta-analyses (26 studies) show higher omega-3 bioavailability than triglyceride/ethyl-ester fish oil — phospholipid-bound omega-3s integrate into cell membranes more efficiently. Small-to-moderate RCTs support triglyceride/cholesterol effects (though the early Bunea 2004 cardiovascular data reported implausibly large effects and is questioned), knee osteoarthritis (2022 multicenter RCT at 4 g/day), skin hydration, and PMS symptoms. Most benefits track its EPA/DHA content delivered more efficiently rather than a unique mechanism. Not an essential nutrient with its own RDA.

What Krill Oil (Phospholipid Omega-3) supports

  • Phospholipid omega-3 — better absorbed than standard fish oil (meta-analyses)
  • RCT support for triglycerides and knee osteoarthritis

How much Krill Oil (Phospholipid Omega-3) to take

The RDA prevents deficiency. The effective range is what clinical trials used to actually move the outcome.

Effective

10003000

mg

1–3 g/day common (knee OA RCT used 4 g). Krill oil is ~15–30% EPA+DHA by weight in phospholipid form, which is better absorbed — ~⅔ the omega-3 of fish oil gives equivalent uptake. Dose reflects total oil, not EPA/DHA content.

Clinical evidence

Moderate clinical evidence. Network meta-analyses show higher omega-3 bioavailability than fish oil; small/moderate RCTs for triglycerides, knee OA, skin, and PMS
