Every batch of oil used in Nordic Naturals' products is third-party tested for environmental toxins including heavy metals, dioxins, and PCBs, ensuring that every product exceeds international quality standards and is at least 750 times purer than fish. Nordic Naturals was ranked #1 out of the top 10 fish oil brands in Norway for freshness, purity, and highest concentration. The key objections to taking fish oils are taste and aftertaste. Nordic Naturals utilizes proprietary enzymatic and oxygen-free processing technologies to ensure no fishy smell, taste, or aftertaste. Our encapsulation process also adds natural fruit essences into both the soft gel and liquid oil for a light, fruity taste. Years of feedback from health professionals and customers alike indicates that children, teenagers, and adults of all ages enjoy the clean, light taste of Nordic Naturals fish oils.
