* Flavour:



While rapid protein digestion is desirable immediately before or after exercise, slower digestion is more appropriate for between meals and right before bed. Casein proteins are pH sensitive and gel in the acidic environment of the stomach. As a result, it can take longer for caseins to be broken-down into their amino acid subcomponents compared to whey and other proteins. Because of their unique slow-digesting qualities, caseins are accurately described as anti-catabolic or muscle-protecting proteins. ON's Gold Standard 100% Casein was the first all-micellar casein and remains the best seller.

100% Casein Protein



A fast-digesting protein is a good choice for right before and after exercise, but delayed digestion may be the better alternative at other times – including bedtime when your body goes for hours without food. Casein proteins can take more than twice as long to be broken down into amino acid subcomponents. For those who leave nothing to chance when planning their diet, Gold Standard Natural 100% Casein is the all-micellar casein made with no artificial flavors or sweeteners.
