ArcticPure uses oil from fish caught in the cleanest and coldest body of water, the Arctic Ocean. A series of advanced distillation processes concentrates and extracts beneficial fatty acids, while guaranteeing the absence of heavy metals and PCB's. Natural flavors give our ArcticPure oils an aroma and taste that is pleasing to both children and adults. Studies show that EPA may provide cardiovascular and joint support, and ArcticPure EPA has one of the highest levels available. In addition, ArcticPure EPA contains protective antioxidants (ascorbyl palmitate, mixed tocopherols, and rosemary extract) for enhanced stability.
