I first saw Airborne on Oprah. She swore she never traveled without it and since she started using it, she rarely, if ever got sick. Ok...I have two kids in school and I worked in a children's retail store. Not only was I constantly surrounded by germs, I didn't have the luxury to let them get to me. So I decided to try Airborne myself. It was developed by a school teacher who was sick of getting sick in the classroom. It has a unique natural formula that contains 17 herbs and nutrients including Vitamin A, C, and E. It also contains ginger to help prevent and relieve nausea. You simply dissolve 1 zesty orange table in some water, let it dissolve for about a minute and drink up. I have taken it at the very first signs of a cold and it really did ward it off! My husband takes it before every business flight and has managed to avoid the former inevitable airplane illnesses since he started taking them! The taste is not bad at all, certainly better than any of the cold medications you would have to take if your were sick! I highly recommend Airborne Effervescent Health Formula.
