Ingredients (52 grams per serving)

Whey Concentrate, Milk Protein Isolate, and Whey Isolate (20 grams per serving)

Our protein bars contain three high-quality forms of protein: whey concentrate (48% of the protein blend), milk protein isolate (34%), and whey isolate (19%).

Why the mixture as opposed to a single type of protein? Softness and stability. All-natural food products are notoriously finicky, and after many recipe tweaks, we hit on the perfect balance of top-shelf protein powders for supporting muscle growth while also optimizing freshness, texture, and shelf life.

Whey Concentrate, Milk Protein Isolate, and Whey Isolate (20 grams per serving)

Prebiotic Fiber (9 grams per serving)

Prebiotic fiber is a partially indigestible fiber found in foods like onions, bananas, and beans that encourages the growth of beneficial bacteria in the gut.[1]

Research shows that regular ingestion of just 5-to-8 grams of prebiotic fiber can . . .

  • Reduce the growth of disease-causing bacteria in the gut[2]
  • Lower “bad” cholesterol levels and the risk of heart disease[3]
  • Decrease the risk of high blood sugar and type ll diabetes[4]
  • Prevent constipation and cramping[5]
  • Decrease appetite and aid in weight loss[6]
  • Increase calcium and magnesium absorption and bone mineral density[7]

Moreover, studies also show that many people don’t get enough prebiotic fiber in their diets, which can raise the risk of various types of disease, including heart disease, cancer, type ll diabetes, and osteoporosis (weak bones).[8][9][10][11]

Every Legion protein bar contains 9 grams of prebiotic fiber in the form of chicory root fiber and soluble tapioca fiber.

Chicory root fiber is a form of prebiotic fiber found in chicory, a plant related to dandelions. We included it in our protein bars because it’s an excellent source of antioxidants and has a pleasant, nutty taste.[12]

Soluble tapioca fiber is a prebiotic fiber extracted from the roots of the cassava plant. We included it because it helps give our protein bars a soft, fudge-like texture.


Nutritious Plant-Based Carbs & Fat (32 grams per serving)

Our protein bars contain 20 grams of carbs and 12 grams of fat from healthy plant foods including cassava, almonds, sunflower, and tapioca, and they’re lightly sweetened with just 4 grams (one teaspoon) of added sugar.

Carbs & Fat

100% Naturally Sweetened & Flavored

No Artificial Food Dyes or Other Chemical Junk

100% Naturally Sweetened & Flavored

While artificial sweeteners may not be as dangerous as some people claim, studies suggest that regular consumption of these chemicals may indeed be harmful to our health.[13][14][15][16][17][18]

That’s why we use the natural sweeteners stevia and erythritol instead. Studies show that these ingredients are not only safe but can also confer several health benefits, including better insulin sensitivity, a lower cholesterol profile, improved blood glucose control, potential anti-cancer effects, lower blood pressure and inflammation levels, and more.[19][20][21][22]

No Artificial Food Dyes or Other Chemical Junk

As with artificial sweeteners, studies show that artificial food dyes may cause negative effects in some people, including gastrointestinal toxicity and behavioral disorders.[23][24][25][26][27]

That’s why we use natural coloring derived from fruits and other foods, as well as natural flavoring.
