• Slow-digesting protein
• 24g of Anti-Catabolic Micellar Casein
• Nearly 5 grams of naturally occurring BCAAs per scoop

Casein proteins are acid sensitive and thicken in the stomach. Compared to some other proteins, it can take more than twice as long for Gold Standard 100% Casein to be broken down into its amino acid sub components. Because of these unique 'time released' qualities, caseins are aptly described as being anti-catabolic, or muscle protecting, proteins.

By using only premium micellar casein as a protein source, ON has created a formula that sets the standard for slow digesting protein support. 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.
