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 pure Canadian harp seal oil sourced from the waters of Newfoundland and Labrador. Provides a complete spectrum of marine omega-3 fatty acids: EPA (eicosapentaenoic acid), DHA (docosahexaenoic acid), and DPA (docosapentaenoic acid). Harp seal oil contains approximately 10 times more DPA than fish oil. The mammalian fat structure of seal oil closely resembles human fat, supporting superior absorption compared to fish oil. Supports cardiovascular health, healthy inflammation response, joint health, and brain function. Health Canada licensed NPN 80045660. Sustainably harvested. No fishy aftertaste. 300 softgels. Not suitable for vegans or vegetarians.
This harp seal oil is sourced exclusively from harp seals (Pagophilus groenlandicus) harvested in the cold waters of Newfoundland and Labrador, Canada. The Canadian harp seal harvest is one of the most closely monitored and regulated wildlife harvests in the world, conducted under strict federal quotas based on scientific population assessments by Fisheries and Oceans Canada. The harp seal population in Canadian Atlantic waters is abundant. The oil is extracted from the blubber of the seal, molecularly distilled to remove impurities, and tested for heavy metals, PCBs, oxidation, and potency before encapsulation. Vitamin E (tocopherol) is added as a natural antioxidant to protect the oil from oxidation.
DPA (docosapentaenoic acid, n-3) is a long-chain omega-3 fatty acid that is structurally intermediate between EPA and DHA. It is found in significant concentrations in marine mammals but is present only in trace amounts in most fish oils. Harp seal oil contains approximately 10 times more DPA than conventional fish oil. DPA serves as a metabolic reservoir for both EPA and DHA in the body: it can be retroconverted to EPA or elongated to DHA as needed, helping maintain stable omega-3 levels over time. DPA has also been studied independently for cardiovascular and anti-inflammatory properties. The combination of EPA, DHA, and DPA in meaningful amounts is unique to marine mammal oils and is not replicated by fish oil or plant-based omega-3 sources.
The molecular structure of fats determines how efficiently they are absorbed and incorporated into cell membranes. Fish oil omega-3s are predominantly in the ethyl ester or triglyceride form with a fat structure typical of fish. Harp seal oil is a mammalian fat with a phospholipid-rich structure more similar to human cell membranes. This structural similarity supports more efficient absorption across the intestinal wall and more effective incorporation into human tissues. Research comparing seal oil and fish oil at equivalent omega-3 doses has shown superior bioavailability for seal oil omega-3s, particularly for DPA.
Non-medicinal ingredients: Gelatin (softgel shell), glycerin, purified water, vitamin E (tocopherol, antioxidant). Contains fish gelatin or bovine gelatin. Not suitable for vegans or vegetarians.
Adults seeking a complete marine omega-3 supplement with EPA, DHA, and meaningful DPA from a Canadian harp seal oil source. A good fit for those who want the DPA advantage not available in fish oil, superior mammalian bioavailability, no fishy aftertaste, and a Health Canada licensed, sustainably harvested Canadian product. Not suitable for vegans or vegetarians. Consult a healthcare practitioner before use if taking blood-thinning medications, scheduled for surgery, have a bleeding disorder, or are pregnant or breastfeeding.
Adults: Take 2 to 4 softgels per day with meals. Dividing doses between meals supports optimal absorption. At 2 softgels per day, 300 softgels provides a 150 day supply. At 4 softgels per day, 300 softgels provides a 75 day supply. Consult your healthcare provider to determine the appropriate dose for your individual needs.
Store in a cool, dry place away from direct sunlight and heat. Refrigeration after opening is optional but may extend freshness. Keep the bottle tightly sealed after each use. Keep out of reach of children.
Consult a healthcare practitioner before use if you are taking blood-thinning medications (warfarin, aspirin, clopidogrel), are scheduled for surgery (discontinue 2 weeks prior), have a bleeding disorder, or are pregnant or breastfeeding. Not suitable for vegans or vegetarians. Keep out of reach of children.
