Protein Bar nutrition facts

*Percent Daily Values are based on a 2,000-calorie diet. Source: USDA FoodData Central.

Around 30g protein per 100g, but a full bar is often 200+ calories — closer to a small meal than a snack. Check whether you actually need the extra protein before adding it on top of meals.

How does protein bar fit your goals?

Protein bar delivers a balanced macro profile (15.2g protein / 19.2g carbs / 7.6g fat per 1 bar (50g)), which makes it easy to fit into almost any tracking plan. Foods like this are particularly useful as base ingredients in meal prep, because they don't lock you into a specific macro split — you can pair them with whatever your daily target needs more of.

Micronutrients worth noting

Beyond the macros, protein bar pulls real weight on fiber (13% DV), calcium (12% DV), iron (15% DV), and vitamin C (16% DV) per 1 bar (50g) — the kind of micronutrient density that calorie counts alone don't show.
