Optimum Nutrition 100% Casein Protein - Slow Digesting Premium Micellar Casein Protein! 24g Of Anti-Catabolic Micellar Casein, 5g Of Naturally Occurring BCAAs And 5g Of Glutamine!

Slow Protein Digestion, Anti Catabolic Micellar Protein With Glutamine!

Sometimes it's good when things take their time, like when protein is being digested in your body. Fast absorption is great before or after exercise, but slow release is better during the day. Casein protein is special because it takes a long time to break down in your stomach. It's in milk and is a high-quality protein because your body uses it easily, giving you the amino acids you need.

One good thing about casein is it makes you feel full. It kind of pushes on your stomach, telling your brain you're full. Casein is the slowest protein to digest, which means it gives your muscles a steady supply of amino acids for a long time. This helps your muscles grow and recover.

People who want to build muscles, keep muscles from breaking down, recover faster, or sleep better can benefit from casein.

Studies on Optimum Nutrition 100% Casein Protein have found some interesting things. One study compared it to whey protein and found that while whey increased protein in muscles by 68%, casein did it by 31%. But casein also lowered how much protein the body breaks down by 34%. This means casein keeps your body in a good balance of making and breaking down protein for about 7 hours after you eat it.

Another study looked at how Optimum Nutrition 100% Casein Protein affects your body when you do weight training. People in one group drank whey protein, and people in another group drank a mix with mostly casein. After 12 weeks, the casein group lost more fat, gained more muscle, and got stronger compared to the whey group.

There are also smaller studies suggesting casein might help lower bad cholesterol and boost good cholesterol. Optimum Nutrition 100% Casein Protein might also help your immune system, especially if it's weak because of illness. And for people with heart problems, it might lower inflammation.

BANANA-Nana-nana-nana!

Great Casein protein. I normally take 30 mins prior to bed. Since taking have not woke up craving a midnight snack. Body seems to maintain weight seeing as I am not fasting for 8 hours. DELICIOUS.
