Carlson Elite Omega-3 Gems® is a professional-strength fish oil concentrate. A single serving provides 1,600 mg of omega-3s, including the important omega-3s EPA and DHA, which promote heart, brain, vision, and joint health. To ensure maximum freshness, Elite Omega-3 Gems® is closely managed from sea to store. We source the highest quality, deep, cold-water fish using traditional, sustainable methods. And like all Carlson omega-3s, they're tested by an FDA-registered laboratory for freshness, potency, and purity.
