Prostar Casein is a high-quality protein derived from milk. It contains 24 g of proteins (micellar casein and hydrolyzed casein) with a gradual release (2 to 7 hours of digestion), which guarantees a constant and continuous flow of amino acids for the recovery and development of muscle mass during the rest period. The consumption of casein before going to sleep optimizes adequate nutrition because it transports amino acids during the entire sleep stage, the moment when the greatest growth and muscle anabolism occur, as well as the natural production of growth hormone, thus obtaining a complete recovery of the muscle and the physical conditions for the next training. Prostar provides only 120 calories per serving, is high in high-quality proteins (24 g of protein), is low in fat, cholesterol and sodium, and naturally provides a high amount of glutamic acid and 600 mg of calcium, an essential mineral for muscle contraction.
