i've been using emergen-C for 2 or 3 years now and it's truly amazing stuff. it's colds and flu season folks, a little extra C and some minerals can keep you going when everyone around you is getting sick. i consider these my secret weapon while traveling too. stale airplane air full of germs is no match for emergen-C. if you're a sports drink lover try the new waters and get all of the emergen-C goodies in a healthier drink than you're used to. oh, and if you've over-imbibed and you wake with a head...these babies replenish what you've lost...all but the brain cells of course.
