The choline content in krill also supports liver and brain function, adding another layer of benefit beyond basic omega-3s. In fish oil, EPA and DHA exist primarily as triglycerides, where three fatty acids are attached to a glycerol backbone.
Clinical Evidence: Fish Oil for Heart Health
The phospholipid structure in krill oil is similar to the membranes of human cells, which may facilitate smoother integration and faster action. While high-quality fish oil is well-absorbed, especially when consumed with a meal containing fats, some studies suggest that the phospholipid form in krill may lead to higher concentrations of EPA and DHA in tissues more efficiently for certain individuals.
Krill is harvested from Antarctic waters under strict international quotas designed to protect whale and penguin populations. Look for certifications like the Marine Stewardship Council (MSC) label on both products.

Krill oil, however, binds these fatty acids to phospholipids, forming phospholipid-bound omega-3s. Fish oil sourcing varies widely; choosing brands that use small, short-lived fish like anchovies and sardines, or that carry third-party sustainability certifications, is the most responsible approach.
