Well I agree about whole foods being best, and being around this forum for as many years as I have, I know most people take way too many supps. But I can sure say my body is resonding to the mix of things I'm using.
That's kinda scary about the NAC, but if I didn't try things on my own I'd be dead or in a wheelchair by now. I was getting nowhere with idiot health care folks ( and poorer to boot ). And I haven't exploded yet from the metal overload despite having a mouth full of Amalgams and taling the NAC several times a day. I think there's something to that whole argument but maybe overplayed a little bit in the alternative health field.
Interestingly juicing always made me worse. Not better. I tried it numerous times and it always made my liver feel overloaded. I tried watering it down...different combos. You name it. Wierd. Great stuff though but maybe my body wasn't ready at that time :-).
