ConsumerLab.com finds fish oil supplements free of mercury, but 30% lacking in key ingredient — Test results of omega-3 fatty acid (EPA and DHA) products released today
Six of the 20 products tested failed to pass the review due to inadequate amounts of the essential fatty acid DHA, which ranged from 50% to 80% of what was stated on the label. Two of these products were also low in EPA, respectively containing 33% and 82% of their claimed amounts. Two of the products that failed actually had statements on their labels that their "potency" had been either "tested" or "verified." None of the twenty products showed evidence of decomposition and none were found to contain detectable levels of mercury (less than 1.5 parts per billion (ppb)). By comparison, mercury levels in fish often range from 10 ppb to 1,000 ppb.
"The good news is that these fish oil supplements did not appear to pose a risk of mercury poisoning — a risk that can be very real when routinely consuming certain fish, such as swordfish and shark. The bad news is that a number of products had significantly less DHA and/or EPA than claimed," said Tod Cooperman M.D., President of ConsumerLab.com. "This could certainly reduce the effectiveness of products. It raises the issue of whether people who are taking omega-3 supplements to prevent or treat heart disease, for example, are getting an effective dose of DHA and EPA from their supplements." Dr. Cooperman added, "If someone is concerned about getting a certain amount of DHA or EPA, it would seem prudent to stick to those products that passed the tests."
