Compositions for oral use containing a zinc compound, a copperncompound, an amino acid and a base material are described.nThe compositions provide for slow release of zinc ions uponndissolution in the mouth to thereby achieve beneficialntherapeutic effects from the zinc ions. The copper compoundnprovides copper ions which serve to counterbalance a largenintake of zinc as is present upon prolonged oral use of thencomposition. A molar ratio of amino acid to zinc of 2 to 20nand a molecular ratio of copper to zinc of 0.1 to 0.01nprovides compositions with a palatable taste and no aftertasteneven upon the inclusion of the copper compound. |
