I've been taking only about 7.5mg of zinc for a while because I have issues tolerating more then that, my serum zinc level was high but on the low end of the range in plasma. Does that mean zinc is not being taken up by the cells? I'm also taking many other B's and some other minerals too.
Also my hair analysis shows zinc has increased a bit with supplementation.
