Supplements: The fda is forbidden by the dhsea act to pass upon the quality of supplements. This includes fish and other oils. Look for a reliable brand but that is not a complete guarantee. Until congress changes this law, we are stuck with unregulated products of uncertain concentration, unknown quality and no ability to detect impurities or toxins.

There is a FDA apptoved product Lovaza with the price tag of $190.99 for a month supply. I am not sure about mercury content in that product. The same factory makes products for certain nutritional supplement companies as well. I strongly suspect that line separates at the labeling phase
