I got my brother hooked on Ener-C when he told me that he nearly collapsed during a noon day trek because of dehydration and fatigue. The ingredients are all "good for you" - good for your stomach, immunity, for antioxidant effect and much more. Of course, staying within the dosage mg recommendation is advised because of the potent Vitamin C content. Taste is a no brainer since the package contains a variety of yummy flavors. Each little packet is just the right size to slip into a pocket. It also works great on stomach acids to aid in digestion. The quality ingredients say it all!
