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 a taste that is pleasing to both children and adults. ArcticPure™ DHA is a concentrated source of the essential brain nutrient DHA. DHA, an omega-3 fatty acid found in fish oil, provides nutritional support for the brain and nervous system. Stabilizing antioxidants (ascorbyl palmitate, mixed tocopherols, and rosemary extract) are added for freshness.
