Our clinical omega-3 supplements contain EPA and DHA concentrations of 70-90% - that's 2 to 3 times more concentrated than standard fish oil. Higher actives mean higher doses of EPA and DHA, in fewer capsules. Our sustainably-sourced omega-3 supplements pass legal limits for PCBs, mercury and dioxins, even before they undergo molecular distillation purification to produce an ultra-pure finished product. We independently test our omega-3 fish oil supplements, guaranteeing the freshest, cleanest oils for the duration of the shelf life.
