1. A method of production of polar krill oil from Euphausia superba comprising:

  • a) treating the Euphausia superba to denature lipases and phospholipases to provide a denatured krill product;

    b) contacting the denatured krill product with a polar solvent to extract a polar krill oil comprising phospholipids, said polar krill oil comprises greater than about 3% ether phospholipids w/w of said polar krill oil;

    from about 27% to 50% non-ether phospholipids w/w of said polar krill oil so that the amount of total phospholipids is from about 30% to 60% w/w of said polar krill oil;

    from about 20% to 50% triglycerides w/w of said polar krill oil, and astaxanthin esters in amount of greater than about 100 mg/kg of said polar krill oil; and

    c) formulating said polar krill oil with a carrier for oral consumption.
