100% Casein is a high protein bodybuilding sports nutrition supplement from Optimum. It delivers 24g of high quality Casein protein and 4g of carbohydrates per serving. Sometimes slower is better - especially when it comes to the rate of protein digestion. While rapid protein absorption is desirable immediately before or after exercise, delayed release is probably more beneficial throughout the remainder of the day. Features: 24 g of Highly Anti-Catabolic MICELLAR CASEIN 10 g of BCAAs, Glutamine, and Glutamine Precursors per Scoop AMINOGEN EnhancedCasein proteins are pH sensitive and gel in the acidic environment of the stomach. As a result, it can take more than twice as long for caseins to be broken-down into their amino acid subcomponents than whey and other proteins. Because of their unique time-released qualities, caseins are aptly described as anti-catabolic or muscle-protecting proteins. Use ON 100% Casein Protein first thing in the morning, immediately before bed in place of small meals, and/or any time when delayed protein absorption is desired. To encourage positive nitrogen balance, consume approximately 1 gram of protein per pound of body weight per day from a combination of high protein foods and supplements. see more...
