"For decades, scientists have been frustrated by the inconsistency in data documenting the efficacy of zinc products," explained author Darrell Hulisz, Pharm D, associate professor of family medicine, Case Western Reserve University School of Medicine. "Recently, there have been a series of well-designed, peer-reviewed clinical studies of zinc gluconate linking this unique ingredient, found in popular OTC products such as Zicam® Cold Remedy, with a significant reduction in the duration of the common cold, as well as the severity of cold symptoms. Common cold symptoms can include: sore throat, stuffy nose, sneezing, coughing, and congestion. It is important to note that the products were most successful when administered within 24 hours of symptom onset."
Hulisz reviewed data sources published between 1980 and 2003. He noted that additional clinical and laboratory evaluations are warranted to further define the role of ionic zinc for the prevention and treatment of the common cold and to clarify the biochemical mechanisms through which zinc exerts its symptom-relieving effects.
