Protein Bar Nutrition Comparison Chart

Protein bars are a healthy and convenient snack option when you’re on the go. But the large variety of protein bars on the market can be overwhelming. We’ve reviewed every protein bar on the market so you don’t have to! Check out our Protein Bar Nutrition Comparison Chart below before you shop to find the right protein bar to suit your needs.

Nutrition Qualities of a Protein Bar

We have reviewed every granola/snack bar, protein bar, and energy bar on the market. Based on our review, to qualify as a protein bar, a bar must contain at least 10 grams of protein, less than 250 calories per bar, and/or be labelled as a ‘protein bar’. In our comprehensive Protein Bar Nutrition Comparison Chart below, you can compare the nutrition facts between different bars to find the right option for your needs.

How to Use the Protein Bar Comparison Chart

As a former grocery store dietitian and consumer, I understand how difficult it can be to select the right products. To save time at the grocery store, review our protein bar comparison chart below to make your decision before you shop. You can sort the table based on the nutrient of concern using the header arrows, or search for your favourite brands in the search box.

Note: we routinely update this Protein Bar Nutrition Facts Comparison chart. However, product formulations may change between updates. Always check the nutrition label for the most up-to-date nutrition facts before consuming a product.

Protein Bars vs. Granola Bars

The main difference between a protein bar and a granola (or snack) bar is the protein content. Based on our review, to classify as a protein bar, the bar must contain at least 10g of protein. That means a granola/snack bar will contain less than 10g of protein per bar. One exception is if the brand markets or labels the bar as a protein bar, then we have included it in this category as well. Each protein bar in our comparison chart below has at least 10g of protein, with the exception of some labelled as a protein bar with lower protein content.

Protein Bars vs. Energy Bars

The nutrition content of protein and energy bars can differ depending on the brand. One key difference is in the number of total calories per bar. We have classified bars with less than 250 calories per bar as protein bars or snack bars. Any bar with more than 250 calories per bar is considered an energy bar. When comparing macronutrient content, protein bars may be similar in protein content to energy bars. However, energy bars are often higher in carbohydrates and fats than protein bars. Each bar included in our comparison chart below contains less than 250 calories per bar.
