Neptune Krill Oil (NKO) is known for its unique fatty acid (FA) profile, as well as for its rich antioxidant content. NKO's balanced fatty acid content includes not only EPA and DHA, the crucial Omega-3 FA's, but Omega-9 FA's and phospholipids, as well. NKO is a rich source of Astaxanthin, a powerful immune-supporting antioxidant. Clinical studies have shown that NKO can support joint comfort, healthy blood lipid levels, and may reduce symptoms of pre-menstrual syndrome.
