Legion Casein+ Ingredients (30 grams per serving)
Truly Grass Fed™ Micellar Casein Protein Powder (26 grams per serving)
Micellar casein is a form of casein protein that has been produced in a way that maximally preserves its slow-digesting properties.
It’s the highest quality casein protein powder you can buy and has a stellar amino acid profile, providing you with 11.4 grams of essential amino acids per serving.
Casein+ is also made with pure Truly Grass Fed™ casein protein, which is made with milk from hormone- and antibiotic-free cows that live the way nature intended—outside, roaming and grazing on grass.
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.[9][10][11][12][13][14]
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. [15][16][17][18]
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.[19][20][21][22][23]
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.
Third-Party Lab Tested for Purity and Potency
Casein+ 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
"There are a lot of sleazy supplement companies out there, but Legion is not one of them. Their products are free of fillers and inactive ingredients and they take the time (and money) to test them with independent labs to ensure you're getting what you pay for."
Dr. Spencer Nadolsky, MD
Board-Certified Family Medicine Physician and a Diplomate of the American Board of Obesity Medicine
"When it comes to quality and integrity, Legion is among the best. Their products only include ingredients that are backed by research and in doses that are proven to be effective in scientific studies."
Sal Di Stefano, Justin Andrews, and Adam Schafer
Hosts of The Mind Pump Podcast
"Legion is a tremendous company run by people I trust and respect. The quality of their supplements is second to no one. And while I don’t use many supplements, the only ones I do come from Legion."
Jordan Syatt
Strength and Nutrition Coach
"Legion consults with nutrition experts to make honest, science-based products and then proves they're genuine with independent lab work. That's how all supplement companies should operate."
Menno Henselmans, MS
Founder of Bayesian Bodybuilding, Published Scientist, and Physique Coach
"Legion's customers are getting some of the best sports supplements on the market."
"Legion Pulse is the best overall pre-workout, especially for energy and focus."
Mix one serving with 8-to-10 ounces of water and drink it whenever it’s convenient—between meals or whenever you haven’t eaten protein for a few hours both work well.
If you have a high daily protein target, prefer Casein+ to eating high-protein foods, or if eating enough protein from whole foods is impractical, you can have more than one serving per day—just try not to rely on Casein+ for more than 50% of your total daily protein intake.
For use around your workouts, take Casein+ within 1-to-2 hours before or after exercising.
Why is Casein+ more expensive than other casein protein supplements?
Casein+ is more expensive than other casein protein supplements because producing a high-quality casein protein powder isn’t cheap, and if you’re paying less than $12-to-15 per pound as a consumer, you’re probably buying junk.
Casein+ comes from small dairy farms in Ireland, which are known for their exceptionally high-quality milk from hormone- and antibiotic-free cows. Casein+ contains no artificial food dyes, junk additives, fillers, soy, gluten, GMOs, MSG, or hormones, and it’s 100% naturally sweetened and flavored.
How much casein protein can I eat per day?
There's no hard and fast rule about how much casein protein you can or should eat per day. Casein protein powder can be used at any time to help you meet your protein needs, but the ideal ratio between whole food and supplemental protein is still an area of scientific ambiguity.
Anecdotal evidence, however, suggests that getting at least 50% of your daily protein from whole food sources is a good rule of thumb.
I’ve heard that eating casein protein after a workout can help me build muscle faster. Is that true?
Yes, it's true that eating casein protein after a workout can help you build muscle faster. It’s a good idea to eat 30-to-40 grams of protein within an hour or two of finishing a workout, and casein protein is a perfectly viable, convenient, and tasty option. Studies show that protein eaten after a workout causes more muscle protein synthesis than when eaten otherwise.
If Casein+ is too sweet/strong or isn't sweet enough for me, what should I do?
If Casein+ is too sweet/strong for you, increase the amount of water you’re using until you find an amount that works for you. (Most people like 8 to 10 ounces.)
If Casein+ isn't sweet enough for you, we recommend you mix it with something other than water that is mildly sweet, like rice or almond milk. You'll find it makes it much sweeter.
What does the Prop65 warning on the labels mean?
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.
Is Casein+ gluten-free or vegetarian?
Yes, Casein+ is gluten-free and also vegetarian-friendly.
Some popular casein protein powders are naturally sweetened and flavored. Some contain 100% micellar casein. Some are made with Truly Grass Fed™ milk. But only Casein+ checks each of these boxes.

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 and BCAAs, like casein, stimulate muscle growth and repair most effectively.

Because shipping a single item is surprisingly expensive.
So blasted expensive, in fact, that on a small order, the shipping cost alone can eat up all of the profits.
However, the economics change dramatically when you bundle, because adding a second or third item to your order costs us very little extra to ship.
And once your order hits the $99 mark (a few items), the math works out, and we can cover the entire shipping cost for you.
Why the $199 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.
