Answer:

Zinc carnosine, also called polaprezinc, is a complex of the essential mineral zinc and carnosine, which is commonly found in meat and fish and is a water-soluble peptide made of two, linked amino acids (its chemical name is beta-alanyl histidine). Zinc carnosine is promoted for the treatment or prevention of a variety of gastrointestinal disorders including stomach ulcers, Helicobacter pylori infection (which can cause ulcers), aspirin-induced small-bowel injury, taste disorders, and oral mucositis caused by cancer treatment. Although commonly prescribed in Japan for some of these conditions, there is very limited evidence supporting its use for any of these applications.

You state that too much zinc can lead to copper deficiency. Is the reverse true? Can too much copper lead to zinc deficiency?

That would be unlikely since the issue is competition for absorption and much smaller amounts of copper are typically taken as a supplement than zinc.
