Docosapentaenoic Acid (DPA) from Seal Oil Retroconversion to EPA and Elongation to DHA in Humans
Journal of Nutritional Biochemistry, 1999
Each softgel delivers 1000mg of wild Canadian harp seal oil (Phoca groenlandica), providing EPA 76mg, DHA 99mg, and DPA 48mg per softgel. A source of omega-3 fatty acids for the maintenance of good health. A source of EPA, DHA, and DPA for the maintenance of good health.
Harp seals (Phoca groenlandica) are wild marine mammals that live in the North Atlantic and Arctic Oceans, feeding on cold-water fish in Arctic waters and migrating south in winter. The oil is extracted from the blubber of wild-caught Canadian harp seals. The Canadian harp seal harvest is regulated by Fisheries and Oceans Canada under federal law, with annual catch limits set based on scientific population assessments. The harvest is conducted by Indigenous and coastal communities in Atlantic Canada and Quebec. The oil is processed in Canada in the natural triglyceride form, with d-alpha-tocopherol (vitamin E) added as a natural antioxidant to protect freshness.
EPA (eicosapentaenoic acid), DHA (docosahexaenoic acid), and DPA (docosapentaenoic acid) are long-chain omega-3 fatty acids found in marine sources. EPA plays a role in the body's inflammatory response and cardiovascular function. DHA is a primary structural component of the brain and retina, essential for cognitive function and vision. DPA is structurally intermediate between EPA and DHA and is found in significant concentrations in marine mammals but in only trace amounts in most fish oils. DPA is naturally present in human blood, heart muscle, brain, and breast milk. The body can convert DPA to EPA or DHA as needed, making it a metabolic reservoir for both.
Fish oil is derived from the flesh of fatty fish such as salmon, mackerel, and sardines. Fish contain EPA and DHA but very little DPA, typically less than 1% of total fatty acids. Harp seals are marine mammals that accumulate DPA in their blubber in meaningful concentrations. Harp seal oil provides all three long-chain omega-3s in one softgel in the natural triglyceride form, the same form found in whole fish and human body fat, which is generally well absorbed.
| Omega-3 | Per Softgel (1000mg) | Per 2 Softgels (2000mg) |
|---|---|---|
| EPA (Eicosapentaenoic acid) | 76mg | 152mg |
| DHA (Docosahexaenoic acid) | 99mg | 198mg |
| DPA (Docosapentaenoic acid) | 48mg | 96mg |
| Total EPA + DHA + DPA | 223mg | 446mg |
| Total Harp Seal Oil | 1000mg | 2000mg |
Adults, adolescents, and children seeking a daily source of omega-3 fatty acids for the maintenance of good health, including all three long-chain marine omega-3s: EPA, DHA, and DPA. A good fit for those who prefer a higher-concentration 1000mg softgel requiring only 1 to 2 capsules per day, omega-3s in the natural triglyceride form from a wild Canadian source, and a Health Canada licensed formula approved for the whole family. Not suitable for vegans or vegetarians. Consult a healthcare practitioner before use if taking blood thinners or other medications.
