Fish oil is a good source of omega-3s. Krill oil is a better one. Onnit Krill Oil delivers EPA and DHA in phospholipid form - the structure that allows fatty acids to cross cell membranes more efficiently than the triglyceride-bound omega-3s found in standard fish oil. Sustainably harvested from Antarctic waters, tested for heavy metals, and naturally rich in astaxanthin. One 30-day supply (60 capsules, 2 per day).

Krill Oil vs Fish Oil - Why the Form Matters

Both krill and fish oil provide EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) - the two omega-3 fatty acids most associated with brain, heart and joint health. The difference is how they're packaged. In fish oil, EPA and DHA are bound to triglycerides. In krill oil, they're bound to phospholipids - the same structural form found in human cell membranes.

This matters because phospholipid-bound omega-3s are absorbed more efficiently and incorporated into brain, liver and lung tissue more rapidly than their triglyceride-bound equivalents. Research comparing the two forms found that krill oil raised plasma EPA levels more effectively than fish oil at equivalent doses.

Krill oil also contains phosphatidylcholine (PC) - a phospholipid that supports choline levels in the body, contributing to normal brain function and liver health. This is absent in standard fish oil.

Astaxanthin - The Built-In Antioxidant

Krill oil contains astaxanthin, a carotenoid antioxidant that gives krill their pink-red colour. Astaxanthin is fat-soluble and travels with the omega-3s through the body, helping to protect the fatty acids from oxidation and supporting antioxidant defence in tissues. Standard fish oil contains no astaxanthin.

Sustainably Sourced, Heavy Metal Tested

Onnit's krill is harvested from Antarctic waters under strictly regulated fishing quotas. Antarctic krill (Euphausia superba) sit at the base of the food chain, which means they accumulate far fewer heavy metals and environmental contaminants than larger fish like cod or salmon. Each batch is tested to confirm it is free of toxic heavy metals before it reaches you.

What Krill Oil Supports

• Brain health - DHA is a primary structural component of brain tissue; EPA supports healthy neurological function
• Heart health - EPA and DHA contribute to normal cardiac function and healthy triglyceride levels
• Joint comfort - omega-3 fatty acids support a normal inflammatory response in joints and connective tissue
• Mood and cognition - adequate omega-3 intake is associated with healthy cognitive function and mood regulation

Directions

Take 2 capsules daily with food. Best taken with a meal containing some dietary fat to support absorption.
