It's good that you are seeing some improvements. Do you have a good practitioner who helps you understand your recent retest? As I like to say, NB is not a do-it-yourself project. It takes someone with good training to help us through this. The fact that your zinc and copper are not coming up likely has nothing to do with absorption but rather with what the body is doing overall. NB is not mineral replacement but rather a complex way of helping the body dump heavy metals and balance the ones we need. It's a long process to get us the place of wellness if we've been ill for a while.

If, for some reason you aren't getting the help you need from your practitioner, PM me, and I can recommend good ones here in the U.S.

Chloride may not be the best choice, switch the form and see if that helps. Copper sebacate from Source Naturals or just Copper Chelate (Solgar).

There are a few good zinc forms, LEF makes a good zinc or use Zinc Chelate.

Heavy metals can inhibit absorption of minerals so this may be considered.
