Solgar® 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. The levels of EPA, DHA, and other fatty acids found in Solgar's softgels – and the proportions of each in relation to one another – reflect those found in wild salmon.
