SLOW-DIGESTING PROTEIN TO FEED EVERY MUSCLE FOR HOURS

Thinking of all athletes and bodybuilders who take their workouts seriously, Prozis presents Xtreme Casein Ultimate. This micellar casein formula provides the body with a slow, sustained release of amino acids to feed every muscle for hours.

Thanks to its slow absorption rate, Xtreme Casein Ultimate is the solution for when your body is deprived of protein for a longer time, such as when you’re asleep or unable to snack between meals.

**PROMOTES MUSCLE GROWTH* WHILE YOU SLEEP**

After a long, hard day, your body deserves a good night’s sleep. But here's the issue: for the next 8 hours or so, your body won’t have any food intake. Does this mean you need to wake up in the middle of the night for a protein fix? Not necessarily.

Sleep doesn’t stop your body. Overnight is simply a long stretch without food intake, and Xtreme Casein Ultimate is a great choice to help you cover that gap. One serving before bed gives you a steady release of protein that contributes to the maintenance of your muscle mass during extended periods without food. Rest easy—this formula works while you sleep.

HOW DOES CASEIN DIFFER FROM WHEY?

TWO WORDS: ABSORPTION RATE.

While whey protein is absorbed quickly, micellar casein is digested more slowly, releasing amino acids gradually over time. This sustained release is particularly suitable for the overnight period, providing protein that contributes to the growth and maintenance of muscle mass.
