The phospholipid form is more water-soluble and is absorbed directly into the cells of the intestinal wall, bypassing the need for emulsification by bile salts. Understanding the Source and Molecular Structure The most basic distinction between krill and fish oil lies in their origin.
Understanding Fish Oil Sustainability and Environmental Impact
While many fish oil products utilize smaller, fast-reproducing species like anchovies and sardifies, making them a generally sustainable choice, krill’s role as a foundational species in the Antarctic food web demands a more cautious and regulated approach to harvesting. Krill, being lower on the food chain, naturally accumulates fewer heavy metals, offering a cleaner profile.
Krill oil, sourced from Antarctic krill, is unique because its omega-3s are bound to phospholipids, specifically phosphatidylcholine. Most fish oil supplements do not contain this natural preservative, relying instead on synthetic antioxidants like ascorbyl palmitate to prevent spoilage, which some consumers prefer to avoid.
Understanding Fish Oil Sustainability and Environmental Impact
This difference means that krill oil may deliver a higher concentration of active EPA and DHA per milligram consumed. Sustainability and Environmental Impact For the environmentally conscious consumer, the sourcing of these supplements is a critical consideration.
