Seal is one of the safest and freshest sources of Omega-3 PUFAs. The mammalian body of a seal is more complex than that of a fish. As a result, seals can “bio-filter” chemical impurities such as pollutants and dioxins with greater ease than fish. Omega-3 PUFAs yielded from seal blubber require less purification because the seal has already cleansed most impurities.
