Wax ester is the natural molecular form of omega-3 in Ruby of the Sea. A wax ester is digested more slowly than other omega-3 molecules (like triglycerides from fish oil and phospholipids from krill oil) and will therefore reach, and activate, important receptors in the distal intestine.These receptors regulate sugar- and fat handling as well as several inflammation processes in the body. Wax esters are considered to be very potent omega-3 molecules.
