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.
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.[10][11][12][13][14][15]
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, a lower cholesterol profile, improved blood glucose control, potential anti-cancer effects, lower blood pressure and inflammation levels, and more.[16][17][18][19]
No Artificial Food Dyes or Other Chemical Junk
As with artificial sweeteners, studies show that artificial food dyes may cause negative effects in some people, including gastrointestinal toxicity and behavioral disorders.[20][21][22][23][24]
That’s why we use natural coloring derived from fruits and other foods, as well as natural flavoring.
Lab Tested for Potency & Purity
Every bottle of Casein+ 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.
No Chemical Junk
Casein+ doesn’t just “contain natural ingredients”—every ingredient is naturally sourced. We don’t use artificial or synthetic substances of any kind.
Clinically Effective Doses
Every ingredient and dose (important!) in our supplements is backed by peer-reviewed scientific research demonstrating clear benefits.
Naturally Sweetened & Flavored
Casein+ is naturally sweetened and flavored with healthy, plant-based sweeteners and flavors.
Lab Tested
Casein+ is tested by third-party labs for heavy metals, microbes, allergens, and other contaminants to ensure it meets FDA purity standards.
Made in USA
Casein+ is proudly made in America in NSF-certified and FDA-inspected facilities in accordance with the Current Good Manufacturing Practice (cGMP) regulations.
