Superior bioavailability? Study backs krill oil over fish oil but not because of phospholipids
Just missing out on top spot is the story that krill oil’s better bioavailability of essential omega-3 fatty acids EPA and DHA compared to fish oil, was not because of differences between phospholipids and triglycerides, as previously thought.
Writing in the journal Lipids in Health and Disease, researchers found that eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) had a higher bioavailability in krill oil than krill meal or fish oil.
“Profiles of EPA and DHA were measured in fatty acids of plasma phospholipids and triglycerides,” explained the team. “We found a larger incremental area under the curve for EPA and DHA in plasma phospholipid fatty acids (primary endpoint) after krill oil, as compared to the other two sources of EPA and DHA."
