I started using FiteBac a few years ago at work and fell in love with it. It proved it’s worth once again on a recent trip to a destination wedding with several family members. We stayed in three different hotels but all sat at the same table during the reception. I used FiteBac faithfully all weekend but my family members did not. When we returned to Atlanta each of them was suffering from stuffy heads or chest congestion while I felt fine. I am convinced my use of FiteBac made the difference and will continue to use it regularly to protect myself from exposure to germs. Smooth hands and feet are an added bonus from regular use of FiteBac! Love this product!!!
