Magnesium and Calcium combo supplements are common here in the states and I believe KAL's "Opti-Zinc" contains some copper.
Dietary intake should also be factored in to the equation, as should be one's "starting point" of stored minerals and/or accumulations. Many believe hair analysis is the only way to properly measure stored minerals and accumulations, and I wouldn't want to take a zinc supp containing copper unless I was confident my copper levels were not elevated (as they commonly are!).
I've quit messing around with most mineral supplementation as deficiencies tend to be less common than accumulations as we age. I take a bit of low dose Mag-Citrate and also some low dose zinc occasionally as I believe these are the most common mineral deficiencies, and Mag and zinc are two minerals I don't want to run short on.
True deficiencies of trace minerals are rare, but imbalances of these are common. Acu-Cell Nutrition has a great site on this here:
