Zinc & Feeling Sick: It is true that Zinc seems to boost the body's immune system which explains why zinc lozenges have been shown to reduce the symptoms of the common cold. However, patients have told me that they have experienced a metallic taste in the mouth following the sucking on zinc lozenges. I would recommend to not exceed the daily recommended dose, drink plenty of fluids, and take zinc with food.
