Great product. I have been using this for years and have not fallen ill for several years, especially in winter when everyone is sick. I cannot receive the flu vaccine, so this does a decent job of shielding me in the harsh months when colds abound. I highly recommend this product as it works exceptionally well. In my healthcare job, I'm often the only one not taken ill, or if I do, it's not as severe as others. I simply love this product!
