How can one choose fish oils with a knowledge of the presence of certain heavy metals?

Dear AW,

Some consumer-oriented sources are beginning such analysis and making this information available for consumers. The website known as www.ifosprogram.com does provide analytical reading reports for mercury and other contaminants (PCBs, dioxins, and furans) in a wide range of supplements containing DHA/EPA which manufacturers and distributors have submitted for independent analysis.
