The Very Finest Fish Oil in Lemon flavor has received numerous awards for its taste and quality. To ensure maximum freshness, we closely manage our omega-3 fish oil supplements from sea to store. We source the highest quality, deep, cold-water fish using traditional, sustainable methods. The same day they're caught, our fish are transported to a highly-regulated rendering facility for initial processing and purification. Once completely purified and flavored in Norway, Carlson liquid fish oil is bottled with a touch of natural vitamin E to prevent oxidation. It's then delivered to us and tested by an FDA-registered laboratory for freshness, potency, and purity. Carlson Norwegian fish oil provides the important omega-3s EPA and DHA which support heart, brain, vision, and joint health.
