Optimum Nutrition 100% casein

Sometimes it is beneficial for a protein to be digested slowly. Before or immediately after training, it is advisable to opt for a fast-digesting whey protein. However, for the rest of the day or in the evening before going to bed, a slowly digesting protein based on micellar casein, like that found in the product 100% Casein Gold Standard, can provide the need for amino acids for several hours. Caseins are sensitive to changes in pH levels and the acidic environment in the stomach. As a result, the breakdown into amino acids can take twice as long for caseins compared to whey proteins or other proteins. Because of this unique delay effect, caseins are referred to as anti-catabolic or muscle-preserving proteins. This is particularly important for bodybuilders and athletes who train intensively and want to boost muscle recovery, prevent muscle breakdown, and reduce recovery time between workouts.
