Nordic Naturals uses the same quality standards and the same oils to manufacture both our human and pet products. The result is Norwegian omega-3 fish oils of industry-leading purity and freshness for your dogs and cats. For centuries, canine and feline diets consisted of unprocessed foods rich in EPA and DHA, omega-3 fatty acids derived from algae, plants, and fish. However, most of today's pet foods contain primarily omega-6 fatty acids from vegetable oils. Even the highest quality pet diets rarely contain adequate amounts of EPA and DHA. This results in an unbalanced ratio of omega-3 to omega-6 that can negatively impact the health of our pets. Nordic Naturals offers two omega-3 fish oil products that are specifically formulated to maximize the health benefits for dog and cat companions.
