Product Description
Casein is the slow-digesting, gel-forming major protein in milk that provides a sustained release of amino acids. It's crucial in cheesemaking, valued in sports nutrition for overnight recovery, and used widely as a functional food ingredient. While beneficial for muscle maintenance and satiety, it is a common allergen and may not be suitable for everyone. Choosing less-processed forms (like micellar casein or whole dairy foods) is generally preferable for health.

Nutritional Composition
100% Casein
Enhanced Satiety & Weight Management
The gastric clotting property increases stomach distension and slows gastric emptying. Its high protein content also stimulates satiety hormones (e.g., GLP-1, PYY).
Dental Health & Enamel Remineralization
Casein phosphopeptides (CPP), released during digestion, have a well-established dental benefit.
Sustained Muscle Protein Synthesis & Anti-Catabolism
Casein's hallmark. In the stomach, it forms a gel or clot, leading to a slow, steady release of amino acids over 4-7 hours.
Bone Health Support
Adequate protein intake is essential for maintaining bone matrix and muscle mass Casein is naturally rich in bioavailable calcium . The CPP peptides further enhance calcium and phosphorus absorption and bioavailability at the bone matrix.
