Seeing and understanding what to expect from other zinc lozenges is important viewing. Did you know that zinc lozenges containing citric acid or glycine are not significantly effective? See this data to understand that there are no active ingredients at physiologic pH for zinc lozenges having as flavorings or flavor-masks citric acid (citrate), glycine (glycinate), and therefore no significant activity.
