Well, I felt based on my reading, that if I had a diet with adequate zinc, which most people have if they eat foods high in zinc like meat, etc. that additional zinc was going to suppress my bio-available copper and consequently my ceruloplasmin creating imbalance. Zinc stimulates a protein that can not only bind to copper, but to zinc. Ironically, I read all the time that people who have quit zinc supplements tested with higher levels of zinc, this could be the reason (the non-stimulation of this metallothionine, not sure of the spelling). I think a small amount of zinc in a supplement may be fine, but the doses seen in most formulas that are 30 mg and over may be causing more problems than they solve. Then of course if you add to that high doses of ascorbic acid (vitamin C), that can mess with copper metabolism as well. Lately, I am trying to get my minerals from food sources, with the exception of magnesium and some selenium. So, I guess in short, to answer your question, is that I am sort of cherry picking the RCP based on what seems to make sense to me, and since I eat things relatively high in zinc, I elected to eliminate it in supplement form and see how it goes.
