Our 100% Norwegian Salmon Oil comes from comes from the clean, pure waters of Norway. Salmon oil is a natural source for Omega-3 essential fatty acids, which are important nutrients for the skin and coat - and for overall health. Many holistic veterinarians feed salmon oil to his dogs and cats every day, and recommends it to all of his patients. More potency without the smell, even though humans can barely smell the scent of Salmon, the dogs and cats go crazy for it. We added more filtration to take out the fishy smell and our oils are Human Pharmaceutical Grade. NOT JUST A COOL BOTTLE: Plastics can contaminate oils as is evidenced by the plastic bottles of oil you see caving in on themselves. We at Iceland Pure are concerned about your pet's health, so we housed our Pure Icelandic oils in brushed aluminum bottles with a micro-thin epoxy coating. This not only prevents cross contamination with the container, but it also prevents any light degradation that may occur in white or clear containers. And they are recyclable! Bottles include handy pumps for accurate dispensing. The important EPA and DHA Omega-3 essential fatty acids are plentiful in salmon oil. And unlike plant-based Omega-3 supplements (such as flax seed), fish oil is readily processed by the digestive system, resulting in more available essential fatty acids per serving. A daily supplement of salmon oil is a must for any dog or cat with skin or coat issues, including those caused by allergies - but it will make a noticeable improvement in the coat of any animal, young or old. During the bottling process in Iceland, our salmon oil goes through a detoxification process that removes virtually all toxins and heavy metals - to the point where they are below detectable levels so that the oil can be called "toxin-free." .
