Re: how much?

Qwer, like you I'm taking a good bit of zinc, around 75mg in supplement and whatever I get via food. I am also taking magnesium supplements and have found significant improvements in my vision, which lets me know that it is in some way improving my mineral deficiencies that resulted from my damaged intestinal tract. If you haven't already seen it, take a look at this essay on magnesium.
