Carlson Super D Omega-3 is a highly concentrated, balanced, professional-strength omega-3 supplement with a delicious, award-winning lemon flavor. It offers 2,000 IU (50 mcg) of vitamin D3 and 1,100 mg of omega-3s per teaspoon, including the most beneficial omega-3s EPA and DHA. To ensure maximum freshness, Super D Omega-3 is closely managed from sea to store. We source the highest quality, deep, cold water fish using traditional, sustainable methods. Our fish are then transported to a highly-regulated Norwegian facility for processing and purification. The fish oil is bottled with a touch of antioxidants and is given a nitrogen flush to remove oxygen and to help prevent oxidation. Like all Carlson omega-3s, freshness, potency, and purity are guaranteed.
