best protein bars

Finding the best protein bars can be challenging since there are so many out there on the market.

Not all protein bars are created equal — many of them are essentially just candy bars with a little added protein!

Look at the nutrition facts labels on your favorite bars to determine the number of calories and grams of fiber, protein, fat, carbohydrates, total sugar, and added sugar. The nutrition content of various protein bars often varies, even if they're made by the same manufacturer.

To pick the healthiest options, make sure to choose high-quality bars with minimal or no added sugar, artificial sweeteners, or fillers. Opt for bars that contain mainly whole food ingredients, such as whey, casein, egg, pea, brown rice, or other protein powders, milk, yogurt, meats, eggs, fruit, nuts, or nut butter.

Pick bars that contain natural sweeteners, such as fruit, stevia, monk fruit, or erythritol. Limit artificial sugars, such as sucralose, as well as artificial colors and dyes.

Look for bars WITHOUT hidden added sugars, such as brown sugar, agave syrup, brown rice syrup, corn syrup, and other syrups.

We lay out some of the best protein bars below. Each one provides at least a few grams of fiber and at least 8 grams of protein, with fewer than 5 grams of added sugar per bar. We also give you some great recipes so you can make your own healthy protein bars at home!
