More about this report

There is also emerging evidence that omega-7s, another type of fatty acid found in fish, and DPA, another omega-3, may have health benefits. But with so many different supplements to choose from, how do you know which one is right for you — and which offers the best value?'s tests of 28 omega-3 and omega-7 fatty acid supplements - including fish oil, krill oil, algal oil, calamari oil, and sea buckthorn oil — revealed problems with the quality or labeling of three products. Fortunately, also identified regular softgels, enteric-coated softgels, and liquids that contained what they claimed and were not contaminated with lead, mercury, cadmium or arsenic. Among these, a substantial daily dose of EPA and DHA could be obtained for as little as a few cents. Among products Approved by, Top Picks were selected for outstanding value.

In addition, top-quality fish oil supplements with very high concentrations of EPA and DHA were found to be comparable to prescription omega-3 drugs, such as Vascepa and Lovaza, but at a lower cost.
