Casein
Casein is a type of protein found mainly in milk and dairy products. It makes up about 80% of the protein in cow’s milk and is known for its slow digestion rate, which provides a steady release of amino acids to the body over several hours. Casein is rich in essential nutrients and is often used in supplements and protein powders to support muscle repair and growth. Because it forms a gel-like substance in the stomach, it helps promote feeling full longer and is commonly consumed before bed or during periods without food.
