Vegetarian-Sourced DHA Blended with Udo's Oil is made with DHA sourced from unrefined algae, not fish, Udo's Oil DHA 3-6-9 Blend offers you vitally important omega-3 fatty acids made from completely sustainable plant sources. A renewable resource, cultivated tank-grown algae has no detrimental impact on worldwide fisheries. We get our DHA (docosahexaenoic acid) the same way fish get theirs-directly from algae. Because it is tank-grown algal sourced, this DHA product is free from ocean-borne contaminants. One serving of Udo's DHA Oil Blend provides 100 milligrams of DHA omega-3 fatty acids combined with Udo's Oil 3-6-9 Blend (a special formulation of natural, unrefined oils from fresh organic flax, sunflower, sesame, evening primrose seeds, and oils from coconut, rice bran, and oat bran).
