198: How to manage the zinc-to-copper ratio?

Masterjohn Q&A Files Episode 198


Question: How to manage the zinc-to-copper ratio?

I don't agree with using the zinc/copper ratio in testing. So it is the case that zinc and copper need to be in a very loose range of ratios. So you don't want your dietary zinc to be more than 15 times your dietary copper, and you don't want your dietary zinc to be less than two times your dietary copper. But other than that, you're really looking at them individually, and you're looking at, do I have enough zinc? Do I have enough copper? Do I have signs of zinc deficiency? Do I have signs of copper deficiency? Do I have signs of too much of one or the other? Much more than you're looking at the ratio.
