People often use protein bars to increase their intake of protein, an important nutrient involved in processes such as immune function, growth, and tissue repair (1).

Protein is also essential for building muscle, especially for athletes and people who are physically active (2).

Protein bars are a great way to help round out your diet, particularly if you have increased protein needs or might have trouble getting enough protein in your diet, which might be the case if you’re vegan or vegetarian.

They’re also a convenient and portable snack option that you can bring almost anywhere, whether you’re traveling, hiking, or simply short on time when you leave the house in the morning.

We considered the following factors when choosing the protein bars on this list:

  • Nutritional content: We looked for bars with at least 10 grams (g) of protein, 3 g of fiber, and 12 g or less of added sugar per serving. Because calorie needs vary, we included bars with 180–270 calories.
  • Ingredients: We paid close attention to ingredient lists, prioritizing bars with minimal amounts of artificial additives such as flavorings, sweeteners, and preservatives.
  • Availability: All the bars below are available throughout the United States and can regularly be found in at least one nationwide grocery store.
  • Taste test: We tested multiple flavors from 25 brands over the course of 2 weeks. During testing, we considered whether the overall taste and texture made a bar satisfying to eat. We also noted whether the bar kept us full for more than an hour.
  • Price: We included products to suit a range of budgets.
  • Vetting: The products on our list have been vetted to ensure that they align with Healthline’s brand integrity standards and approach to well-being.

No Cow Chunky Peanut Butter

  • Price: $$
  • Taste: sweet peanut butter flavor with a noticeable alternative sweetener aftertaste
  • Texture: chewy and chalky, with some texture from peanut pieces

If you’re trying to shed a few pounds, choosing a protein bar that’s relatively low in calories but high in fiber and protein may help you reach your goal (8, 9).

Providing 17 g of fiber, 21 g of protein, 0 g of added sugar, and fewer than 200 calories, the No Cow Chunky Peanut Butter bar is a good option if you’re watching your weight.

To keep the bars free of added sugar, No Cow uses several sugar alternatives, including stevia, monk fruit, and sugar alcohols, all of which impart a noticeable aftertaste.

However, during testing, we found the aftertaste to be less pronounced in the Chunky Peanut Butter flavor. Similarly, while the bars are a bit chalky, the peanut pieces in this flavor add a nice boost of texture.

Instead, it reminded us of a Reese’s Fast Break candy bar, with a rich peanut butter center, a milk chocolate coating, and a soft, slightly chalky, melt-in-your-mouth texture.

All think! keto protein bars are gluten-free, keto certified, and free of artificial sweeteners.
