Do You Have A Copper and Zinc Imbalance?

Unlike zinc, copper can readily accumulate in the body into toxic concentrations. In order to maintain adequate zinc levels, a higher dose of zinc compared to copper is required daily. Zinc is only stored for short durations in the blood and bone and is quickly excreted through our urine and fecal matter. ( 7)

Can you store copper sulphate solutions in a zinc pot ...

Copper is less reactive than zinc. Zinc will replace the copper from its salt solution. When the copper sulphate solution is stored in a zinc pot, copper is replaced by zinc, in the copper sulphate solution. Zn + CuSO 4 → ZnSO 4 + Cu. So copper sulphate solution cannot be stored in a zinc pot.
