Second, the amount of fiber in a protein bar can also have an impact on your stomach, Jones says. While fiber is an important nutrient for regulating your digestion and increasing feelings of satiety, some bars contain a lot of it (often in the form of oats, nuts, or other plant-based sources like chicory root). And eating a bunch of fiber in one sitting may cause bloating, cramping, and gas, especially if you’re not used to it.

Finally, you may want to skip a bar if collagen is listed as its sole source of protein, Jones recommends. You don’t have to worry about it from a digestion standpoint, but collagen isn’t the best choice for protein supplementation. That’s because it isn’t a complete protein (meaning it doesn’t contain the nine essential amino acids your body needs) and won’t adequately support your body’s recovery process, she explains.

Other than that, it’s mainly a matter of personal preference—for example, if mint chocolate chip flavors remind you of brushing your teeth after dessert, you know to avoid those types of bars.
