Fish Oil for Dogs and Cats Iceland Pure Unscented Sardine-Anchovy Oil offers many well-documented health benefits to people and their pets, and the list keeps growing. Iceland Pure Sardine-Anchovy oil provides a potent, highly digestible source of essential fatty acids (EFAs) and is loaded with the omega-3 fatty acids DHA and EPA, the EFAs most strongly linked to the health benefits of fish oil. This 100% pure Sardine Anchovy oil undergoes a molecular distillation process that takes only 45 seconds at 250 degrees C under high vacuum. This shortening of the "sit" or "residence" time for processing greatly improves the quality because it guarantees that no trans fats are created. This natural purification process also removes virtually all toxins and heavy metals to produce a level of purity so high that the oil can be labeled "toxin-free." Support your dog's health with Iceland Pure Sardine-Anchovy Oil.
