Did you know that “grass-fed” is a slippery term that can mean “ate a blade of rotten grass on the way to the factory feedlot” or “has always eaten nothing but lush grass in the rolling meadows of Arcadia” or anything in between?

That’s why Whey+ is made with Truly Grass Fed™ milk, which comes from hormone- and antibiotic-free cows that live the way nature intended—outside, roaming and grazing on grassland.

Unsurprisingly, happy and healthy cows make the best milk, and the best milk makes the best whey protein.

That’s why Whey+ is made with Truly Grass Fed™ milk from Animal Welfare Approved (AWA) certified farms where the cows spend their entire lives roaming freely on rich pastures and open ranges.

Although genetically modified organisms (GMOs) may not be as harmful as some people would have you believe, many consumers are skeptical of GMOs and prefer to avoid them.

That’s why Whey+ contains no GMOs and why the Truly Grass Fed™ milk it’s made with meets the strict Non-GMO Project Standard for GMO avoidance.

Many dairy farms boost milk production by injecting their livestock with the genetically engineered hormone rBST, which, as with GMOs, many consumers prefer to avoid.

That’s why Whey+ is made with Truly Grass Fed™ milk, which comes from farms committed to rBST-free practices.

Sugar isn’t the metabolic bogeyman it’s often made out to be, but a sugar-free protein powder does offer several benefits:

1. It has fewer calories per serving, making it more “fitness friendly.”
2. It’s more compatible with popular diets like low-carb and keto.
3. It can help maintain steadier energy levels and curb cravings.

That’s why Whey+ contains no added sugars of any kind, including sucrose, high-fructose corn syrup, fructose, maltodextrin, or dextrose.

Legion Whey+ Ingredients (25 grams per serving)

Truly Grass Fed Whey Protein Isolate Powder (22 grams per serving)

Whey protein isolate is a form of whey protein that has been processed to remove fat and lactose. It’s the highest quality whey protein powder you can buy and is at least 90% protein by weight, which means it contains minimal calories, carbs, and fat.

What's more, Whey+ isn't just "grass-fed" but is made with pure non-GMO Truly Grass Fed certified whey protein isolate.

This is significant because in the United States, there's no legal definition for "grass-fed" dairy. A company could feed cows grain most of their lives, let them nibble some grass, and call their meat and milk "grass-fed." Even "100% grass-fed."

Without third-party certification, grass-fed claims are basically an honor system. The company is simply asking you to trust them. And in an industry that's infamous for "creative" (misleading) marketing claims, that's a bad bet.

A gold standard of proof is Ireland's non-GMO Truly Grass Fed™ certification—95% grass diet, 250 days on pasture, with actual inspectors verifying compliance.

And that's why Whey+ delivers what other "grass-fed" proteins only promise: guaranteed quality produced by ethical farming.

Research shows that supplementation with whey protein . . .

There’s no clinically effective dose of whey protein. Instead, use Whey+ to help reach the recommended intake of 0.8-to-1 gram of protein per pound of body weight per day (or 1 gram per centimeter of height per day if you have a significant amount of weight to lose).

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

Naturally Sweetened and 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 natural sweeteners like stevia, erythritol, and monk fruit instead. 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.[26][27][28][29]

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.[30][31][32][33][34]

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.

No Artificial Food Dyes or Other Chemical Junk

Third-Party Lab Tested for Purity and Potency

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.

And research shows that proteins rich in EAAs, like whey, stimulate muscle growth and repair most effectively.
