Fish oils are fats found in fish, particularly fish which live in deep, cold water fish such as sardines, salmon, mackerel, cod, and tuna. Fish oil is thought to be healthful because it is composed of rich sources of long-chain polyunsaturated fatty acids of the omega-3 type. The two most heavily researched fish oils are eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA). Salmon oil would be considered fish oil although some companies choose to market it differently.
Flax seed oil comes from the Flax seed. This natural oil (also known as Linseed Oil) is highly recommended for the general well being and whole body nutrition and is considered to be nature's richest source of omega-3 fatty acids that are required for the health of almost all body systems.
Flax Seed Oil contains omega-6 and omega-9 essential fatty acids, B vitamins, potassium, lecithin, magnesium, fiber, protein, and zinc and also provides approximately 50% more omega-3 oils than what you could get from taking fish oil.
