For anyone who quit protein shakes because of what they do to your stomach
Most whey sits in your gut like a brick.
This one has the enzymes built in. You get 25g of protein without the bloat that ruins your afternoon.
You know the feeling. You drink your shake. Twenty minutes later your stomach turns. You feel heavy. Gassy. Puffed out through the middle.
So you skip the shake. Then you miss your protein for the day. Then you wonder why nothing changes.
Most people blame the protein. It is usually not the protein. Your body just cannot break it down fast enough.
That is the part you never have to think about again.
Every scoop has DigeSEB® enzymes blended in. They go to work the moment the shake hits your stomach. Not dusted on top. Mixed through, at a real dose.
Here is what you get in one scoop.
25g of protein. 135 calories. 2g of fat. 1g of sugar. And 3,150mg of leucine, the amino acid that actually tells your muscle to grow.
Now here is how you check that claim yourself.
Look at the glycine on the panel. It is low. Just 1,290mg.
Cheap brands pump glycine in to fake a bigger protein number. The trick is called amino spiking. It is legal. It is everywhere. And it means you paid for protein you did not get.
We print all 18 amino acids on the tub. Every one. So you can check us the same way you should check everybody else.

Frequently Asked Questions
Will Nitro^UP make me bloated?
Less likely than plain whey. The DigeSEB® enzymes help you break the protein down before it can sit on you. If dairy itself is your problem, our ISO^UP isolate is lower in lactose.
Is Nitro^UP good for building muscle?
Yes. You get 25g of protein and 3,150mg of leucine per scoop, which is what your muscle needs to repair after training. More in whey protein for muscle gain.
Is it an isolate or a blend?
A blend. It is creamier than pure isolate and easier on your wallet, with the enzymes added. If you are cutting and want the leanest option, pick ISO^UP instead. See isolate vs concentrate vs blend.
When should I drink it?
Whenever you need to hit your protein for the day. After training, between meals, or as a snack. Your daily total matters more than the timing. See how much protein per day.
What is amino spiking?
It is when a brand adds cheap free-form aminos like glycine to inflate the protein number on the label. You pay for protein you do not get. Check the glycine line on any tub you own. Ours is 1,290mg, and all 18 aminos are printed.
Is this good for a beginner?
Yes. It mixes easily, it tastes good, and it is gentle on your stomach. That makes it an easy first protein.
