This is something that's been bugging me a lot. Many folks here recommend the Radiant Life and Green pasture high vitamin cod liver oil, two of the options on the weston price site. I used a bottle of the Green Pasture, and I'd love to start using it again, but what third party certifier tests the Green Pasture product for mercury? I see numerous assurances that it's safe, I've read about it's source, the methods used to preserve the vitamins, all of that stuff. What I have not read is a stamp from a independent third party certifying it's safety. I do find that stamp on Nordic Naturals and Carlson's, which unfortunately are not high vitamin.
I Really, Really, Really would like to use the HVO; our family has severe tooth decay and it really bothers me that I can't seem to get any independent verification of purity. All the safety claims appear, and this may be due to limitations in my research, to come from people who stand to profit.
Can someone point me in the right direction here?
