Neptune Krill Oil (NKO) is known for its unique fatty acid (FA) profile, which includes EPA and DHA, plus phospholipids. In addition, NKO naturally has Astaxanthin, a powerful free radical scavenger and immune-supporting carotenoid. Clinical studies have shown that NKO can help to support joint comfort, healthy blood lipid levels already within normal range. It is tested to be free of potentially harmful levels of contaminants (i.e. mercury, heavy metals, PCB’s, dioxins, and other contaminants).
