How It Works
How It Works
Micellar casein forms a gel-like substance in your stomach, creating a slow, sustained release of amino acids over several hours. This extended delivery helps maintain positive nitrogen balance during long periods without eating, particularly overnight when your body typically goes 6-8 hours without protein.
Who It's For
Athletes and fitness enthusiasts who train regularly and want to maximize recovery during sleep. Anyone looking to maintain muscle mass during weight loss or extended periods between meals. Those who prefer a thicker, more filling protein shake.
Who It's Not For
People who need fast-absorbing protein immediately post-workout should choose whey instead. Not suitable for those with milk allergies or severe lactose intolerance.
About This Product
What It Does
Gold Standard Casein delivers sustained amino acid release for up to 7 hours, making it the proven choice for overnight muscle recovery. Unlike whey protein that digests quickly, this micellar casein forms a gel in your stomach that slowly breaks down, providing your muscles with a steady stream of building blocks while you sleep.
Why It Works
- SUSTAINED RELEASE: Micellar casein's unique structure creates hours-long amino acid delivery, preventing muscle breakdown during extended fasting periods.
- COMPLETE PROFILE: 24g of complete protein with all essential amino acids, including 4,950mg glutamine and precursors for recovery support.
- ENHANCED ABSORPTION: Aminogen enzyme blend helps your body actually use the protein more effectively than standard casein formulas.
What's Inside
Premium micellar casein protein with natural and artificial vanilla flavoring. Enhanced with Aminogen digestive enzymes and inulin fiber. Contains milk ingredients.
Why we carry it: Optimum Nutrition's reputation for quality control and third-party testing ensures you get exactly what's on the label — no compromises on purity.
