According to the results of scientific work, where data from 28 controlled studies were analyzed, zinc shortens the duration of influenza and SARS and prevents the appearance of signs of illness. For example, if zinc is taken prophylactically, it will reduce the risk of mild symptoms by 28 percent and moderate symptoms by 87 percent. Jennifer Hunter, PhD in Integrative Medicine, is the lead author of the study.
If we talk about taking zinc as a supplement after catching the flu or a cold, then this substance can reduce serious symptoms of the disease in a couple of days. Of course, the effect is quite insignificant. In addition, as scientists note, if a person is specifically trying to infect ARVI, then zinc will already be useless.
