A method of preparing a zinc citrate-containing oral care composition, the method comprising: (a) adding zinc oxide to a solution of citric acid in a solvent to form a suspension； (b) agitating the suspension until a clear solution is obtained； and (c) adding an additional oral care ingredient to the solution obtained in (b). Also, a method of preparing a zinc citrate-containing oral care composition, the method comprising: (a) adding citric acid to a suspension of zinc oxide in a solvent； (b) agitating the suspension until a clear solution is obtained； and (c) adding an additional oral care ingredient to the solution obtained in (b). In both methods, steps (a) and (b) are carried out at a temperature of from 10°C to 50°C and the molar ratio of zinc oxide to citric acid in step (a) is about 3:2.
