Zing Bars are made by four Seattle-based nutritionists, naturopathic physicians and acupuncturists. Zing bars are gluten free, wheat free and soy free. HealthE Goods offers all flavors of the Zing Bars in case quantities or single bars so you may sample them. You will not be disappointed. The Zing Bars are full of quality forms of protein and provide good nutrition for those moments in need of a snack. Dr Ben is extremely picky when it comes to energy bars which is why you only see three companies offered at HealthE Goods. Zing Bars made the cut - easily.
