- Workouts don't happen just in the gym or on the trail. A day of hard work takes a toll on your body. Your muscles need protein to recover and rebuild. Clif Builder's gives you 20 grams of soy and nut proteins in a delicious, dipped double-decker bar.
Clif Builder's bar is the perfect way to get through a hard day's work. And unlike other protein bars, a Clif Builder's bar has no trans fats or hydrogenated oils. They're crispy, tasty and entirely natural. (from Clif)
