Was down for 6 weeks with severe cough and cold signs. read your very thorough and informative article on Zinc Acetate, which addressed the correct form and how to use it. Had tried many home-based and supplemental approaches, including my PCP's recommendations, without relief from any of them. Gave your Zinc Acetate a try and it did the job! If I ever have a cold again, my first approach for a remedy will be your Zinc Acetate.
