I know of no studies where fish sources

There needs to be on whether taking life'sDHA is as or more effective than eating cold-water fish. We went to an expert, Marian L. Neuhouser, Ph.D., R.D., at the Fred Hutchinson Cancer Research Center for a balanced view.

Here is what she had to say: "Until a randomized trial can be conducted in humans, comparing the effects of cold-water, oily fish to the effects of marine algae on several biomarkers or other health outcomes that are measurable in a relatively short-term study, one simply cannot make these claims.

I know of no studies where fish sources and algae sources were compared for efficacy in a double-blind placebo-controlled trial (even in animals). Such evidence would support algae sources as a reasonable substitute for fish sources. Until then, I think one can only state that despite the fact that marine algae is being added to numerous food products as a means to supplement the foods with EPA/DHA (since juices and other foods do not naturally contain these fatty acids), there is insufficient evidence to conclude that consuming foods with these supplements is a substitute for consuming dark, oily fish and that the will Softgels be comparable."
