Primary Outcome Measures:
  • Bioavailability [ Time Frame: 1 month ]

Enrollment: 24
Study Start Date: May 2011
Study Completion Date: November 2012
Primary Completion Date: December 2011 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Krill Oil Dietary Supplement: Krill oil
Krill oil:Total omega-3 fatty acids: 560-660 mg and Astaxanthin: 1800 µg
Experimental: Fish Oil Dietary Supplement: Fish Oil
Fish oil: Total omega-3 fatty acids: 560-660 mg

Detailed Description:
The main purpose of the study is to evaluate the absorption of omega-3 fatty acids into the blood following consumption of krill oil compared with fish oil and placebo. An additional purpose is to evaluate the lipid-lowering efficacy and safety of consumption of Krill Oil and Fish Oil to a placebo product. It has been shown that the ingestion of Krill Oil leads to better absorption of omega-3 fatty acids compared to ingestion of Fish Oil. It was also shown that consumption of krill oil and fish oil result in a favorable modification of lipid profiles. Therefore, it is anticipated that consumption of these krill oil and fish oil will improve lipid profile, as well as other health-related markers and will be safe and well tolerated.
