I take flax SEED oil. There are plenty of government sponsored studies that reflect concern about mercury in fish oil suppliments and in certain oily fish groups out of the NIH, with wording that has caused them to recommend reducing intake of the fish itself ( which includes the oils in the meat) altogether. And who can guess who the "better manufacturers" are? Most are private label brands and the original manufacturer/producer is unknown to the public. For my money I'll take a flax seed oil suppliment where none of this is an issue.
