Even though I like to have these by my side during flu season. I do like to take an Emergen-C every now and then to give me that boost of vitamin C. Right now you can get a free sample of Emergen-C drink mix. You will get (1) free original Emergen -C and (1) Emergen-C Super Fruit. Just go over to Emergenc.com then put in your personal information. Your sample will arrive in 6-8 weeks.
