About this product

Optimum Nutrition Naturally Flavored Gold Standard 100% Casein Drink Mix is a slow-digesting protein powder formulated to support muscle recovery during sleep. Each serving provides 24 grams of micellar casein, a high-quality protein that breaks down gradually to help maintain muscle mass and reduce overnight breakdown. The creamy vanilla flavor comes from natural sources, and the mix contains 4.9 grams of naturally occurring BCAAs to aid in post-workout recovery. With zero fat and no artificial ingredients, this powder helps promote satiety and supports weight management goals. It's made in the USA and designed for use between meals or at bedtime.
