Gold Standard 100 % Casein 924 g by Optimum Nutrition is the benchmark for slow-absorbing proteins, strategically designed to nourish muscles during prolonged fasting periods. Unlike fast-digesting whey proteins, micellar casein forms a gel in the stomach that steadily releases amino acids. This makes it the ideal night-time supplement. Each serving provides 24 grams of casein, ensuring muscles receive nutrients for up to 8 hours, protecting and repairing tissues while you rest. With a high concentration of BCAAs and naturally sourced glutamine, this protein not only provides anti-catabolic benefits but also supports the immune system. Gold Standard Casein is perfect for athletes and those on fat-loss diets, effectively helping to control appetite. With low sugar and fat content, it’s the ideal choice for those looking to improve performance and recovery.
