Sign-up for the e-mail newsletter from Emergen-C and you become eligible to request free samples. Their drink mixes are designed to give your immune system a boost while providing 24 nutrients. Whether you drink Emergen-C every morning, after a workout or only during flu season this free sample could come in handy.
Also, on the Emergen-C Facebook page they are offering a free sample of their children’s formula. I’m not sure if you can take advantage of both of these samples since you have to sign-up for the newsletter each time but it’s worth a try.
