HI there, I can't say for sure Carlson's is bad because it's probably one of the better ones that some of them! But obviousy it does contain trace amounts which might be enought o self off more sensitive people. At any rate, you could just be extra safe and try a brand like Nordic Naturals as Dallas mentioned or a brand called Blue Ice. As I hear these are thoroughly tested.

Yeah it's hard to try and do everything I know. Even diet alone, just knocking off sugar or something can be very hard because your body becomes used to it and addicted and when you stop using it, you go into detox and you can feel worse and start craving like crazy because the yeasts want you to keep feeding them and if they don't get what they want, they begin to weaken and die off and will try and get you to eat sugar! Plus as they starve to death, they release their own toxins into your bloodstream for a time, which can make a person feel temporarily worse, but improvement comes after it and sometimes it's tremendous for some people.

but don't feel bad if you find it too much, it's there if you feel like giving it a go. Not everybody wants to do it, but if you really feel horrific? It "might" be a key in improving your health.
