Power Crunch is truly the Next Evolution of the Nutrition Bar." Just like the flagship product Proto Whey, BNRG has created the most unique protein-energy bar available. Unlike all those hard, chewy extruded bars, Power Crunch is a delicious, crme-filled wafer cookie, bursting with Proto Whey protein. High in protein, low in sugar and carbohydrates. Di and tripeptide rich protein (see Proto Whey) allows for rapid and maximum protein absorption.
