Its natural oil is among the purest of all ocean fish. Wild Alaskan Sockeye Salmon is also one of the premium sources of EPA and DHA—the Omega-3 fatty acids that most people consume too little of, and that make this fish uniquely healthful. 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.Solgar's Full Spectrum Softgels provide an excellent source of Vitamin D3, an essential vitamin that supports many areas of wellness, including, bone and immune health.
