yes, there certainly can be too much of a good thing, there is such a thing as zinc toxicity, but it's worth getting tested i reckon. there seems to be quite a bit of debate in the research about zinc and ms specifically. i don't have it pieced together yet. the best bet site says lots of ppl with ms have zinc deficiency. the literature doesn't really seem to support that contention. but i got tested and was quite seriously deficient... so from where i sit the science can debate all it wants.
