Zinc Toxicity?

Is there an amount of Zinc that would be considered dangerous?

If you eat well and you multi-vit has Zinc, would also taking ZMA be too much?

Would it be better to take a multi without Zinc and take ZMA or would it be better to take the multi and not take ZMA but use Mag and B6 instead (no Zinc)?

Thanks, Rene’

I’m doing both right now, just to try the ZMA for sleep help. Anecdotally speaking, I’ve notice zero negative effects from all the multi-vitamins and the zma combo. However, I honestly don’t think the ZMA is doing SFA either.
