Zinc and copper depletion

Posted by Glydin on January 27, 2005, at 6:55:51

This is technically not related directly to mental health matters, but I thought I would ask away anyway.

Years ago I took zinc for skin matters prior to having info that informed me of copper depletion being a factor in long term use.

Does anyone know any cutoff point - as in, a low dose of zinc would not cause this to be an issue? I've read conficting information.

Any input would be appreciated

Anything up to 40 mg/day is believed to not affect copper, but that includes a safety factor as well. Deliberate inhibition of copper uptake by zinc (as a treatment for Wilson's disease) uses many times that dose.

The treatment for inhibited copper uptake is simply to stop the zinc, so any effect from long ago is no longer an issue (if that's what concerns you).
