The supplement I take is made of purified deep sea fish oil from anchovies & sardines & adds lemon oil & rosemarry extract. With 1060mg EPA/gel capsule, 274 mg DHA/gel capsule & 202mg of other omega3s. It also adds vitamine E derived from refined soybean oil. This was the only pharmaceutical grade omega 3 brand (nordic naturals) that I found in searching & then found that it was the one my pdoc recommended anyway.
