Bioavailability of Fatty Acids from Krill Oil, Krill Meal and Fish Oil in Healthy Subjects
Krill oil had higher 72-hour EPA+DHA bioavailability than fish oil, but krill meal and fish oil had similar bioavailability, arguing against phospholipid superiority.
En crossoverstudie med 15 friska personer jämförde 72-timmars biotillgänglighet av EPA+DHA från krillolja och fiskolja. Krillolja hade högre biotillgänglighet. However, krill meal and fish oil were not significantly different, which argues against the interpretation that phospholipids are better absorbed than triglycerides. The authors noted large inter-individual variability and recommended longer-term studies using red blood cell EPA+DHA (the Omega-3 Index).
EPA and DHA in krill oil had a higher 72-hour bioavailability than in krill meal or fish oil. Our finding that bioavailabilities of EPA and DHA in krill meal and fish oil were not different argues against the interpretation that phospholipids are better absorbed than triglycerides.
Small sample (n=15), single-dose design, short follow-up (72h). A 2024 metaanalys of 26 studies found krill oil superior at doses under 2,000 mg but high-dose fish oil was more effective for raising the Omega-3 Index.
