If you don’t like something of ours, guess what happens next?
No, we don’t request you deliver it to a PO box in the Gobi Desert by carrier pigeon. Nor do we ask you to fill a cursed inkwell with orc’s blood and demon saliva and then use it to complete reams of return forms written in ancient Cyrillic script.
We just . . . wait for it . . . give you every penny of your money back. Holy moo cows. And that means you can say "yes" now and decide later.

Legion Protein Cereal Ingredients (40 grams per serving)
Milk Protein Concentrate (17 grams per serving)
Milk protein concentrate is a protein powder made by filtering milk to significantly increase the protein content while reducing the amount of lactose and water. It typically comprises around 80% casein and 20% whey.
This is why research has shown that milk protein concentrate can be equally effective as whey protein for stimulating muscle protein synthesis.[1]
Milk protein concentrate is also perfect for making protein cereal because it provides a satisfying crunch, clean flavor, and long shelf life—without the sogginess, grittiness, or earthy aftertaste typical of grain-based protein cereals.
Prebiotic Fiber (7 grams per serving)
Prebiotic fiber is a partially indigestible carbohydrate found in foods like asparagus, onions, and garlic that promotes the growth of beneficial gut bacteria.[2]
Our protein cereal contains two kinds: chicory root fiber and soluble tapioca fiber.
Chicory root fiber comes from chicory, a plant related to dandelions. It’s a rich natural source of inulin—a prebiotic fiber with antioxidant properties that supports gut health.[3][4][5]
Soluble tapioca fiber is extracted from the roots of the cassava plant and helps give our cereal a light, crunchy texture.
Research shows that consuming 5-to-8 grams of prebiotic fiber per day . . .
Each serving of our protein cereal contains 7 grams of prebiotic fiber—enough to deliver meaningful health benefits without disrupting digestion.
Nutritious Plant-Based Carbs & Fat (21 grams per serving)
Our protein cereal contains 15 grams of carbs and 6-to-7 grams of fat from healthy plant foods including tapioca, chicory root, coconut oil, and stevia, and it’s sweetened with just 4 grams (one teaspoon) of added sugar.
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.[11][12][13][14][15][16]
That’s why we use the natural sweetener stevia instead. Research shows that this ingredient is not only safe but can also confer several health benefits, including better nutrient absorption, healthy cholesterol levels, and more.[17][18][19][20][21][22]
No Artificial Food Dyes, Fillers, or Other Unnecessary Junk
As with artificial sweeteners, studies show that artificial food dyes and fillers can cause negative effects in some people, including gastrointestinal toxicity and behavioral disorders.[23][24][25][26][27]
That’s why we use natural coloring and flavoring derived from fruits and other foods as well as naturally derived ingredients for improving texture, enhancing shelf life, and facilitating the manufacturing process.
Lab Tested for Potency & Purity
Our protein cereal is tested by a state-of-the-art ISO 17025-accredited third-party laboratory for heavy metals, microbes, allergens, and other contaminants to ensure compliance with FDA purity standards.

"Legion is science-based at its core. Not only do they dose all of their products based on the clinical doses proven to be effective by scientific studies, they go above and beyond the their competitors by funding new research."
Dr. Bill Campbell, PhD
Professor of Exercise Science at University of South Florida

How many servings come in each box?
6.
What are the calories and macros for your protein cereal?
Each serving contains 170 calories, 17 grams of protein, 15 grams of carbohydrate, 7-to-8 grams of fiber, and 6-to-7 grams of fat.
How does your protein cereal compare to other popular protein cereals?
The first thing you’ll notice is how much better our protein cereal tastes and feels in your mouth. It’s light, crunchy, and has a subtly sweet flavor—not soggy, gritty, or earthy like most high-protein breakfast cereals made with wheat, soy, or pea protein.
We also use premium milk protein concentrate, which is more effective at supporting muscle growth and easier for your body to absorb than the grain-based proteins found in most other options.
And thanks to a balanced blend of prebiotic fibers, it’s high in fiber and easy on your stomach.
Your cereal costs more than other protein cereals. Why should I buy it over cheaper alternatives?
In many cases, cheaper cereals are made with lower-quality protein sources like soy, wheat, or pea protein, which are harder to digest, less effective at supporting muscle growth, and often leave a gritty, earthy aftertaste.
Many also have a short shelf life and include undesirable ingredients like artificial sweeteners, flavors, food dyes, fillers, and other unnecessary junk.
Our high-protein cereal, on the other hand, is made with premium milk protein concentrate, which delivers 17 grams of high-quality protein per serving. It’s also highly bioavailable and has a complete amino acid profile, making it ideal for building and maintaining muscle.
It contains 7-to-8 grams of prebiotic fiber per serving, too, which supports digestion and overall health.
And no, we didn’t skimp on taste.
Each bite delivers the light, crisp crunch and subtle sweetness you expect from regular cereal—not the chalky imitation you get with most high-protein options.
How many “active” or “net” carbs are in each serving of your protein cereal?
Technically, each serving contains about 7-to-8 grams of “active” carbs, but that doesn’t mean you should only “count” that many if you’re tracking your macros (macronutrients).
Although the 7-to-8 grams of “nonactive” carbs are from fiber 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 15 grams of carbs in our protein cereal.
How should I store your protein cereal?
Keep your protein cereal in a cool, dry place and reseal the box after each use to maintain freshness.
Is your protein cereal lactose-free?
No.
Our protein cereal contains milk protein concentrate, which contains lactose.
Is your protein cereal gluten-free?
Yes.
Our protein cereal doesn’t contain gluten.
Is your protein cereal keto friendly?
No.
Our protein cereal wasn’t designed to be keto friendly as it’s intended for the everyday person who doesn’t follow any particular style of dieting.
Is your protein cereal vegetarian friendly?
Yes.
None of the ingredients are derived from meat.
Is your protein cereal vegan friendly?
No.
Our protein cereal contains milk protein concentrate, which is made from milk.
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. That’s why we use the natural sweetener stevia instead.↑
2.
Unlike many of the grain-based proteins used in other protein cereals, milk protein is more easily absorbed and offers a complete amino acid profile, making it better for supporting muscle growth.↑
3.
The primary reason we need to eat protein to gain and retain muscle is to obtain the 9 essential amino acids (EAAs) our body can't synthesize, including the 3 branched-chain amino acids (BCAAs).
And research shows that proteins rich in EAAs, like milk protein, stimulate muscle growth and repair most effectively.↑

Why the $80 minimum purchase amount for free shipping?
To quench our piggish lust for grubby profits in the eternal service of the dread lord Mammon?
Kind of. But not really. Because here's the truth:
Single-item orders are so blasted expensive to ship that we make very little profit on them. And no profits make the bean counters lose their marbles.
But when you order just one more item, it only costs us a few dollars more to ship both of them to you. Add a third item, and it's just a few more shekels to ship.
And that allows us to make a profit. Which keeps the bean counters happier than a hammer in a nail factory.
So, if it pleases your Grace, we humbly request your mercy and patronage notwithstanding the vexing free shipping minimum.

Many supplement ingredients lack scientifically validated benefits for healthy humans—we aren’t large rodents, after all—and those that do often use doses too low to be effective.
That’s why we exclusively use ingredients and doses proven effective in peer-reviewed scientific studies on healthy men and women.

If you want to ensure the supplements you’re swallowing every day are safe and effective, you want to buy from a company that:
Sources ingredients from premium suppliers around the world (great supplements require great raw materials)
Tests all products for purity and potency in accredited third-party laboratories (to conclusively verify safety and efficacy)
Manufactures final products in America (which has some of the strictest regulations in the world)
Which is exactly what we do here at Legion.
Did you know that some supplements contain dangerously high levels of toxins like lead, arsenic, and cadmium?
That’s why we rigorously test every ingredient in each of our supplements for heavy metals, microbes, allergens, and other contaminants, ensuring they meet the strict purity standards set by the FDA.
While artificial sweeteners, food dyes, and fillers may not be as dangerous as some people claim, studies suggest that regular consumption of these chemicals may indeed be harmful to our health.
That’s why we use natural sweeteners like stevia, erythritol, and monk fruit instead as well as natural coloring and flavoring derived from fruits and other foods.
Research shows that these ingredients are not only safe but can also confer several health benefits, including better nutrient absorption, healthy cholesterol and inflammation levels, and more.
The proprietary blend is little more than a sneaky way to use tiny (ineffective) amounts of lots of ingredients and hope customers don’t know any better.
