Compositions for oral use containing a zinc compound, a copper compound, an amino acid and a base material are described. The compositions provide for slow release of zinc ions upon dissolution in the mouth to thereby achieve beneficial therapeutic effects from the zinc ions. The copper compound provides copper ions which serve to counterbalance a large intake of zinc as is present upon prolonged oral use of the composition. A molar ratio of amino acid to zinc of 2 to 20 and a molecular ratio of copper to zinc of 0.1 to 0.01 provides compositions with a palatable taste and no aftertaste even upon the inclusion of the copper compound. |
