Deal updates for Protein Bar, Chocolate Sea Salt
RXBAR prints its whole ingredient list on the front of the wrapper: dates, egg whites, nuts, cocoa and sea salt. Each 52 g bar has 12 g of protein and 5 g of fiber, with its 14 g of sugar coming from the dates rather than added sugar — a whole-food bar that's been a grocery best-seller for years.
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.
