Zinc gluconate lozenges can reportedly prevent viruses from spreading in your throat when you're sick. A study that tested the effectiveness of zinc for sore throats concluded that, compared to placebos, zinc decreased the recovery time of scratchy throats, coughs, runny noses and sneezing. Great news, but remember that while zinc lozenges are great for treating colds, they shouldn't be taken once your cold is gone; they can counteract other good nutrients in your body.
