This product is truly amazing. I work in a corporate office and once one person gets a cold, EVERYONE gets the cold. However, this is no longer the case with me. I take it as soon as anyone gets sick around me and/or as soon as I feel the first twinge in my throat. It has worked wonders as i'm always the person who not only catches the cold, but catches it and then it turns into an evil respiratory infection or even pneumonia. I've not gotten sick ONCE this year taking it - even with my both of my bosses getting the flu! I have both the spray and the nasal spray, which I take when my allergies are particularly bad and it has also been so helpful. Highly recommended!
