Optimum Nutrition Gold Standard 100% Casein

Sometimes it is advantageous for a protein to be digested slowly. Before or immediately after training, one should naturally prefer a fast-digesting whey protein. However, for the rest of the day or in the evening before going to bed, a slowly digestible protein based on micellar casein, such as that found in the product 100% Casein Gold Standard, can meet the amino acid needs 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. Due to this unique delay effect, caseins are referred to as anti-catabolic or muscle-preserving proteins. This is especially important for bodybuilders and athletes who train intensely and want to boost muscle recovery, prevent muscle breakdown, and reduce recovery time between workouts.
