Deal updates for Builders Protein Bar, Chocolate Peanut Butter
CLIF Builders is the bigger, heartier bar from the energy-bar brand: 68 g, 290 calories and 20 g of plant protein. Hikers and lifters pick it when a 150-calorie snack bar won't do and they want real fuel after a long session.
The number on this page comes from the Supplement Facts panel: protein per serving as printed on the label. Scoop sizes differ between brands (roughly 30–40 g of powder), so compare protein per serving and servings per container, not scoop counts.
Powder usually gives more protein per dollar and per calorie; bars win on convenience. Check the same two numbers on both: protein per serving and calories per serving.
