Highlights From Clinical Trial
Consumption of 3 g/day krill oil for 4 weeks increases plasma and RBC concentrations of total omega-3 PUFA, EPA, and the sum of EPA and DHA compared to fish and corn oil in healthy humans. Krill oil consumption also resulted in a significant decrease in omega-6:omega-3 ratio compared to fish oil and control treatments.
Krill oil consumption resulted in an elevated omega-3 index compared to consumption of fish oil and control oil treatments, emphasizing the efficiency and higher bioavailability of krill oil over fish oil.
Results indicate that the bioavailability of krill oil omega-3 PUFA might be more pronounced compared with that of fish oil, likely due to the structural differences between these two marine oils.
