Casein protein powders are a popular supplement among fitness enthusiasts and athletes. They are made from a slow-digesting protein found in milk and are designed to provide a sustained release of amino acids to the muscles over a longer period of time. This makes them ideal for use before bed or during periods of fasting, as they can help to prevent muscle breakdown and promote muscle growth. Casein protein powders are also a convenient way to increase daily protein intake and can be mixed with water or milk for a quick and easy post-workout shake.
