Optimum Nutrition Gold Standard 100% Casein

Optimum Nutrition Gold Standard 100% Casein is the World’s No. 1 and the industry’s first all-micellar Casein. Recommended for use in the evening, casein 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.

Gold Standard 100% Casein shake contains 24g of the purest protein, only 3g of carbohydrates, but just 0.5g of fat and no sugar.
