ONCE UPON A TIME...Protein drinks were milky, flat, and full of fat...but not anymore

Each can of XAPP contains 40 grams of lightly carbonated Liquid Whey Protein Isolate, infused with nitrogen (N₂) for extra power. 9.4 grams of BCAAs and 5.2 grams of Leucine make XAPP the most effective way to refuel and repair muscle. All this packaged in a great tasting drink that has only 170 calories. 2 grams of carbs. ZERO fat, ZERO lactose. And it’s caffeine-free, making XAPP the perfect essential fuel for your body after a workout.

After exercise is when your body needs protein the most—when your tank is on "empty." That's why XAPP is most effective when taken immediately following a workout (within 30 minutes). University studies have confirmed that the faster protein enters the body, the quicker and more thorough your recovery. Next time you work out, your body will feel the difference. For maximum refreshment, enjoy XAPP well-chilled – just above freezing.

What began as a random experiment 8 years ago led to a breakthrough in the world of drinkable protein. Two men, a seltzer bottle, a devotion to protein and a constant desire to make things better became the genesis of XAPP—the world’s first carbonated protein beverage.

In May of 2002, David Jenkins and Shawn Sherwood were discussing a problem fitness fanatics have had for years—protein drinks were what the body craved post-workout, but they tended to taste awful and sour. A quick trip to the local supermarket, and the experimenting began. By adding ordinary seltzer water, the taste improved dramatically. Sherwood and Jenkins knew they were on to something.

In the years that followed, the two set to work, tweaking and perfecting the product, and backing up their ideas with science. And in October of 2009, their theory was proven—researchers at the University of California, San Diego made some startling discoveries about human taste buds. 

They discovered the carbonation found in seltzer was being tasted on the same grouping of taste buds that detect sour flavors. So when you drink a carbonated protein drink, the fizz and the sour taste are competing for space on the same protein receptors, resulting in a taste that’s distinctly less sour.

Soon, though, the duo encountered a setback—the dried whey protein they were using created a foamy mess during larger production runs. The time spent to correct this would make the drink too expensive to mass-produce. Their manufacturer suggested an anti-foaming agent, but Jenkins and Sherwood were unwilling to compromise their ideals. They didn’t want to taint such a pure product with nasty chemicals. And then it hit them—the problem was with the dried whey protein. Could the solution be as simple as—liquid whey protein?

A new supplier, a few more tests, and once again, a breakthrough. This wasn’t just a manufacturing solution, the liquid whey protein created a cleaner product all around. There were no flavor off-notes, no scorched particles of protein, and no mold counts. And to top it all off, they reduced their carbon footprint by eliminating the protein-drying stage. By now it was clear that liquid whey protein was the way to go, so Sherwood and Jenkins went to the patent office to secure their future.

The final obstacle was getting the carbonation levels just right. They went through hundreds of experiments, from super-fizzy drinks to nearly undetectable bubbles, and when they had one they were happy with, they went to the people. They let dozens of strangers try the drink, and received an overwhelming response on the fizz, the flavor, and the overall experience.

With a carbonation level that's perfect from beginning to end, XAPP is here—ready to help you work out smarter, faster, and more thoroughly than ever before.
