Casein protein is a slow-digesting protein that can provide sustained release of amino acids to the body. It is widely used by bodybuilders, athletes, and fitness enthusiasts as a dietary supplement to support muscle growth, recovery, and fat loss. Casein protein is derived from milk and is rich in essential amino acids, especially the branched-chain amino acids (BCAAs) leucine, isoleucine, and valine.
Consuming casein protein before bedtime can help to prevent muscle breakdown during the night when the body is in a catabolic state. It can also help to improve satiety and reduce hunger, making it a good choice for those who are trying to lose weight or maintain a healthy body composition. At our store, we offer a wide selection of high-quality casein protein supplements from trusted brands such as Optimum Nutrition, MuscleTech, and Dymatize. Shop now to support your fitness goals!
