SPECIALLY FORMULATED: Our organic casein protein has been specially formulated to provide a high protein content of 78%, making it an excellent choice for individuals who strive for optimal recovery, muscle building and muscle retention. One of the outstanding features of our organic casein protein is its exceptional solubility. It dissolves effortlessly in water or any other liquid, ensuring smooth and convenient consumption.
100% ORGANIC - Try our 100% organic casein protein powder from the milk of happy grass-fed cows. The cows run freely and eat healthy grass all year round to provide you with natural goodness. Our powder is carefully made without hormones, GMOs or soy, so you get pure food. No artificial substances or added sugar. It is a clean and healthy source of protein for your fitness and well-being, while protecting the environment.

Only a high-quality ingredient: this protein is made from 1 ingredient, pure and high-quality organic casein protein concentrate. It contains all the important amino acids, including BCAAs that support muscle growth and recovery. No unhealthy additives, chemicals or added sugars. It is important to know that our protein contains lactose, which can cause allergies in some people.
Delicious, creamy and neutral taste: enjoy the neutral and tasteless character of our organic casein protein powder. It can be easily incorporated into recipes and drinks and preserves the original taste without overlaying it. Whether you're making smoothies, making a delicious protein shake, or baking treats, you can enjoy the benefits of a protein supplement while enjoying the delicious flavors you love.
