Grizzly Krill Oil does not contain omega-3 fatty acids like other fish oils, but instead contains omega-3 lipids (phospholipids). Due to their chemical structure, phospholipids act much like an emulsifier that assists your dog in absorbing nutrients. Lipids are very important elements in all cell membrane structures; providing a variety of phospholipids in your dog’s diet helps maintain healthy membranes in the digestive tract, further benefitting overall nutrition absorption.
