PolarPower is the world’s only truly unrefined whole food fish oil made from wild sockeye salmon heads. This is what the grizzlies eat, so you know it is good for you: omega 3s plus naturally occurring vitamins A & D. In fact, PolarPower is the superior source of naturally occurring vitamis A & D, rarely seen together in any other fish oil supplement. It is a also a dense source of the potent antioxidant, astaxanthin. Use PolarPower to support your daily nutritional needs and to also to support a healthy whole body hormonal system, cardiovascular system, and heart health, along with supporting the health of all the mucous membranes throughout the body. You need whole food (not synthetic) vitamin A to make secretory IgA, and that’s the immunoglobulin that protects the tissue linings from attack.
