Legion Protein Bars 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.
Prebiotic Fiber (6-9 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.[8]
Research shows that regular ingestion of just 5-to-8 grams of prebiotic fiber . . .
- Reduces the growth of disease-causing bacteria in the gut[9]
- Lowers “bad” cholesterol levels and the risk of heart disease[10]
- Decreases the risk of high blood sugar and type ll diabetes[11]
- Prevents constipation and cramping[12]
- Decreases appetite and aids in weight loss[13]
- Increases calcium and magnesium absorption and bone mineral density[14]
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, type ll diabetes, and osteoporosis (weak bones).[15][16][17][18]
Every Legion protein bar contains 6-9 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.[19]
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.
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.[20][21][22][23][24][25]
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, enhanced cholesterol profile, lower inflammation levels, and more.[26][27][28][29]
No Artificial Food Dyes, Fillers, or Other Unnecessary Junk
As with artificial sweeteners, artificial food dyes aren’t a hazard per se, but studies show they can cause negative effects in some people, including gastrointestinal toxicity and behavioral disorders.[30][31][32][33][34]
That’s why we use natural coloring derived from fruits and other foods, as well as natural flavoring.
Third-Party Lab Tested for Potency & Purity
Every box of Legion protein bars is analyzed in a state-of-the-art ISO 17025 accredited lab to verify what is and isn’t in it. That way, you know exactly what you’re getting and putting into your body.

Frequently Asked Questions
Enjoy a Legion protein bar whenever you want a delicious, high-protein, and low-calorie snack. And if you want to make it even more ooey-gooey delicious, microwave your bar for 15 seconds before eating.
12.
No.
For now, we're only offering full boxes but may be able to offer individual bars in the future!
Each bar contains 240 calories, 20 grams of protein, 24 grams of carbohydrate, 9 grams of fiber, and 12 grams of fat.
Because while most types of carbohydrate contains about 4 calories per gram, carbs from fiber and erythritol contain less.
Specifically, insoluble fiber contains no calories, soluble fiber contains about 2 calories per gram, and erythritol contains about 0.2 calories per gram.
Thus, to convert the bar’s macros to calories, you need to differentiate between the grams of carbohydrate that contain 4 calories and those that contain less.
They’re better, duh! ;-)
The first thing you’ll notice is how much better our protein bar tastes and feels in your mouth. It’s fresh, moist, and chewable, and many customers say it tastes more like a candy bar than a protein snack.
We’ve also taken special care to ensure our bars are easy on your stomach, which is often a problem with other naturally sweetened, high-fiber protein bars.
And while you may not realize it, your body and muscles will appreciate that we’ve used only high-quality sources of protein (whey concentrate, milk protein isolate, and whey isolate) instead of cheaper options like calcium caseinate and soy protein.
If you have a sensitive stomach or something in our bars just doesn’t seem to sit right with you, there are three things you can do:
Keep eating the bars and see what happens.
If you’re new to our bars and are experiencing gastrointestinal distress, you might find that after a week or so of eating them regularly, your stomach adjusts and symptoms simply disappear.
Eat the bars less frequently.
For instance, some people find that one bar every 24 hours or so is perfectly fine, but if they eat two in the same time frame, their stomach will get upset.
Eat the bars slower with more liquid.
Instead of slamming bars down in a few bites with no liquids, try eating them slower while sipping on a beverage in between bites.
We decided to use a blend of whey concentrate, milk protein isolate, and whey isolate because they’re more or less equally effective for gaining muscle and together produce an outstanding texture and mouthfeel (better than whey alone and whey plus micellar casein, which we also tried).
You can certainly find cheaper protein bars, but what are you getting for your money?
In many cases, you’re getting bars that...
Contain low-quality forms of protein, like calcium caseinate and soy protein.
Contain a number of other undesirable ingredients, including corn syrup, maltodextrin, artificial sweeteners, dyes, and flavors, and other chemical junk.
Taste mediocre at best, and often much worse.
Our protein bars are different.
They contain 20 grams of a blend of some of the highest-quality types of protein you can buy: whey concentrate, milk protein isolate, and whey isolate.
What this means is every gram of protein in every Legion bar you eat can be efficiently and effectively used by your body to build muscle, recover from workouts, and support health and weight loss.
They also contain 9 grams of prebiotic fiber, which supports your overall health and well-being in a number of ways.
Additionally, our protein bars are naturally sweetened and flavored with stevia and erythritol and contain absolutely no fillers or artificial sweeteners, flavors, dyes, or other chemical junk.
That doesn’t mean we skimped on the taste, either.
We worked on samples for nearly a year to ensure that every bite of our bars is savory, moist, and pleasantly chewable. Our goal was to create a bar that tastes like high-protein candy, and many of our customers say we’ve done just that!
Technically, each bar contains about 15 grams of “active” carbs, but that doesn’t mean you should only “count” that many if you’re tracking your macros (macronutrients).
Although the 9 grams of “nonactive” carbs are from fiber and erythritol and contain fewer calories than the “active” carbs, they still contain calories.
Therefore, if you want to be as accurate as possible in your calorie and macro tracking, we recommend you simply count all 24 grams of carbs in each bar.
Yes, but not in a “bad” way.
Your blood sugar levels will rise after eating one of our bars, but the increase will be relatively small and sustained, meaning there won’t be a crash or other negative aftereffect.
No.
Our bars contain whey concentrate, which contains lactose.
Yes.
Our bars don’t contain gluten.
No.
Our bars weren’t designed to be keto friendly as they’re intended for the everyday person who doesn’t follow any particular style of dieting.
Yes.
None of the ingredients are derived from meat.
No.
Our bars contain whey protein, which is made from milk.
Our products include a Proposition 65 warning in compliance with California’s regulatory guidelines, which are among the most stringent and sweeping in the world.
A Proposition 65 warning does not indicate whether a product is safe or unsafe. Rather, Proposition 65 is a consumer notification law in California that requires warnings to inform consumers about the presence of one or more of over 900 substances in various types of products. These substances include naturally occurring and ubiquitous compounds, even when present at levels below those known to cause harm.
