Grizzly Salmon Oil is derived only from wild Alaskan Salmon that have spent their entire lives foraging on a natural, nutrient rich diet. The resulting oil contains a balanced blend of valuable fatty acids, inherent antioxidants and traces of vitamins that naturally occur in the salmon, which will not interfere with your dog's intake of vitamins from other sources. Grizzly Salmon Oil supplies a daily supplement rich in EPA and DHA the right Omega 3 fatty acids. Your dog's metabolism uses these nutrients immediately without any prior conversion. Plant based omega 3 fatty acids, such as those found in flax seed, must be converted by your dog's body prior to use an inefficient process that may result in as little as 5 % 15 % of the fatty acids being actually metabolized. Grizzly Salmon Oil is a sustainable Omega 3 solution: no fish is caught for the purpose of making oil. Instead, our Omega 3 oils are a co product of the production of high quality seafood products for humans. This enables more of the fish to be utilized in a better way for the benefit of our pets.
