UPC: 748927026283
Optimum Nutrition Gold Standard 100% Casein is a slow-digesting protein powder designed to support muscle recovery during periods without food, such as overnight or between meals. It provides 24 grams of micellar casein protein per serving, which the manufacturer notes digests more slowly than whey to deliver amino acids over an extended timeframe. Each serving also includes 9 grams of naturally occurring essential amino acids and is fortified with magnesium and zinc.
This product is recognized as one of the first 100% micellar casein protein powders on the market. It carries the Informed Choice certification, indicating it has been tested for banned substances by an anti-doping lab. The manufacturer states it mixes easily with just a glass and spoon and is available in multiple flavors, including Chocolate Peanut Butter, Chocolate Supreme, Cookies & Cream, and Creamy Vanilla. It is manufactured in the USA from ingredients of domestic and international origin.
