Solgar’s Full Spectrum Omega Wild Alaskan Salmon Oil Softgels are carefully manufactured from Wild Alaskan Salmon that were sustainably caught from the pristine, cold waters of Alaska. These softgels go through a proprietary purification process to ensure removal of heavy metals, including mercury, PCBs and other environmental impurities, while still maintaining optimal integrity of the oil and potency. This oil complies with the quality specifications for Omega-3 oils set forth by the CRN monograph, which is advocated by the Global Organization for EPA and DHA Omega-3s (GOED).
