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 Crispy Treats Ingredients (55 grams per serving)

Whey Concentrate, Whey Hydrolysate, Milk Protein Isolate, and Casein (15 grams per serving)

Whey concentrate is a protein powder made from fresh dairy whey—the liquid left over after cheese is made. It’s filtered to remove excess fat and lactose while preserving its protein content and quality.

Whey hydrolysate is whey protein (often whey isolate) that is then treated with enzymes to break the protein into smaller fragments. This “pre-digestion” generally makes it quicker to absorb and easier to digest than non-hydrolyzed forms.

Milk protein isolate is a protein powder made by filtering milk to increase its protein content while removing most of the fat and lactose. It naturally contains about 80% casein and 20% whey protein.

Casein is a protein powder made by separating curds from milk, then cleaning, drying, and processing them into a powder.

Our protein crispy treats contain a form of casein called caseinate, which is casein combined with minerals like sodium or calcium to improve mixability and texture.

Although these four protein powders are produced and metabolized differently, research shows all four effectively support muscle growth.[1][2][3][4][5][6] Moreover, they’re also ideal for high-protein snack foods because they ensure a consistently soft, chewy texture, maintain a pure flavor, and offer extended shelf life.

Grass-Fed Whey Protein Isolate (22 grams per serving)

Prebiotic Fiber (4 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.[7]

Our protein crispy treats contain 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.[8][9][10]

Soluble tapioca fiber is extracted from the roots of the cassava plant and helps give our protein crispy treats a light, crunchy texture.

Research shows that consuming 5-to-8 grams of prebiotic fiber per day . . .

  • Reduces the growth of harmful gut bacteria[11]
  • May support healthy lipid levels[12]
  • Supports digestive health and regularity[13]
  • Reduces appetite and supports weight management[14]
  • Supports bone health[15]
Grass-Fed Whey Protein Isolate (22 grams per serving)

Nutritious Plant-Based Carbs & Fat (27 grams per serving)

Our protein crispy treats contain 27 grams of carbs and 8 grams of fat from healthy plant foods including tapioca, chicory root, cashews, almonds, and coconut oil, and they’re sweetened with just 4 grams (one teaspoon) of sugar.

Grass-Fed Whey Protein Isolate (22 grams per serving)

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.[16][17][18][19][20][21]

That’s why we use the natural sweeteners allulose and tapioca syrup instead. Not only are these ingredients safe, but research also shows that allulose may also confer several health benefits, such as supporting appetite control, fat loss, antioxidant activity, and more.[22][23][24][25]

No Artificial Food Dyes or Other Chemical Junk

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.[26][27][28][29][30]

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.
