More than a dozen studies have shown that zinc supplementation reduces the incidence of cold symptoms and the duration of illness. Zinc can also inhibit the growth of cold-causing viruses. For sore throats, Perque Zinc Lozenges can be taken every two hours while symptomatic. Frequently, people take too little zinc and do not receive full benefit. This is a complete, immune-building formula. Other zinc lozenges not only lack synergistic nutrients for immune enhancement, but also commonly use poorly absorbed, insoluble or poorly available forms of zinc. Perque Zinc Lozenges are the perfect chewable daily zinc supplement and immune system enhancer for children. They can be especially useful for children with poor growth and appetite.
