Optimum Nutrition Casein Protein provides a slow-digesting protein source ideal for overnight muscle support and sustained recovery. Unlike whey, casein digests gradually, releasing amino acids for up to eight hours, making it perfect before bed or during long periods without food. Each serving contains 24g of high-quality protein with naturally occurring BCAAs and glutamine, essential for repair, growth, and maintaining lean muscle. The Creamy Vanilla flavor offers a smooth, satisfying shake that mixes easily with water or milk, creating a dessert-like texture. With 2lb per tub, it provides a reliable supply for athletes focused on recovery and muscle retention. Low in fat and sugar, it supports lean diets while ensuring muscles remain fueled even during rest. Casein is especially beneficial for preventing overnight muscle breakdown and promoting optimal recovery. Trusted by athletes worldwide, Optimum Nutrition delivers consistent quality and effectiveness. This product ensures you stay anabolic, recover properly, and build muscle even while you sleep.
