Finding the Right Protein Bar

  • Protein Content: By design, protein bars contain fairly high levels of protein—generally 10 grams or more per bar—and some may contain as much as 30 grams. When comparing different products, look at how much protein comes in each bar and assess how it fits into your nutritional needs.
  • Nutritional Content: Protein content isn’t the only thing you should look at as you shop. Also consider the calories, fiber content and sugar content. Sometimes protein bars contain high levels of sugar to improve the taste, but this might not align with your health goals. Also keep in mind that sugar alcohol, which is often used as a sweetener, can cause an upset stomach when eaten too frequently or in large quantities, especially if you have a sensitive stomach.
  • Flavor(s): Protein bars are available in every flavor under the sun, from decadent chocolate to fruity strawberry and fun birthday cake. You may want to look for a protein bar that comes in a variety of flavors, which will allow you to try different options each week.
  • Cost: Protein bars can be quite pricey, especially if you’re looking at specialty products. It’s important to consider your budget and how often you plan to eat the bars. If you’re going to have one every day, you’ll likely want a more budget-friendly product. Otherwise, you may find yourself shelling out a lot of money each month to keep up the habit.

Evaluation Criteria

To compile this list, we relied on a combination of personal experience and user reviews. We’ve tried several of the protein bars included, but for those we haven’t tested, we looked for highly rated products and read through dozens of user reviews, evaluating what reviewers said about the product’s taste, texture and price.

We selected products that contain 10 grams of protein or more, and the majority of our picks are less than 300 calories and contain less than 10 grams of sugar. (There are a few exceptions, which we qualify below.)
