Product Description. Highly refined, pharmaceutical grade seal oil omega-3 capsules. Unlike most fish oil and flax oil products, DPA GOLD Omega-3 Capsules contain naturally balanced levels of eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA) and docosapentaenoic acid (DPA) omega-3 essential fatty acids.
What is omega-3 DPA? Docosapentaenoic acid (DPA) is a dietary omega-3 fatty acid mainly found in fish, fish oil, seal oil and red meat. Its biological properties have not been thoroughly studied. Unlike, the other popular omega-3 fatty acids (EPA and DHA), DPA has not been extensively subjected to research due to the limited availability of the pure compound.
