We are Max & Jess, the founders of The PRTN Bar. Our journey started like many others: we kept seeing high protein recipes, shakes, and meals online. At first, we thought it was just a trend. But the more we experimented ourselves, the clearer it became that it is more than that. It is a lifestyle and something your body has always needed.
We realized that for years we had been eating too little protein. Because of that, we felt tired more quickly, stayed hungry longer, and found losing weight harder than it should be. Once we started getting enough PRTN, we noticed the difference right away: better recovery, more muscle retention, and a steadier energy level. We also discovered how important it is to start the day with a protein rich breakfast. It provides satiety, stabilizes your blood sugar, and gives your body the right fuel to start strong.
Along the way we tested everything, from whey to vegan blends, from classic dishes to viral TikTok recipes. We learned how many different kinds of PRTN there are, how to calculate what your body needs (weight × grams per kilogram), and that the amount even varies between training and rest days. We found that eating too little PRTN is the biggest mistake many people make, leaving them feeling weaker and holding them back from reaching their goals.
But our exploration did not stop with PRTN alone. We dug deeper into what your body needs for balance and recovery. For athletes, supplements like magnesium and creatine turned out to be essential. We even discovered the benefits of plankton, which surprisingly supports energy and recovery. Most importantly, we saw how nutrition and supplementation directly influence your hormonal balance.

How it all started
Jess & Max
As women, we have personally experienced how difficult hormonal imbalance can be from low energy to skin issues and mood swings. What often goes unnoticed is how much nutrition and supplements influence this. By addressing it, we felt the difference: more calm, more strength, and more balance. That personal experience is something we carry into The PRTN Bar, because we believe it still receives far too little attention.
That is why we do things differently. Of course, there are already places that offer healthy meals, but nowhere is PRTN as central as it is with us. With us, everything revolves around protein. Transparent, concrete, and simple. You know exactly how much PRTN you are getting and why it matters.
And we make it fun. Everything that goes viral online in the high PRTN world, we bring straight to our menu. With our Viral Weekly, you can try a new meal or snack every week, from sweet to savoury. This way, we bring the online hype to the street, so you do not have to stand in the kitchen yourself.
The PRTN Bar is much more than a hospitality concept. It is our story, our journey, and our community. We combine our personal discoveries with the power of PRTN, supplements, and lifestyle. Not a trend, but a new way of eating, living, and feeling. And we invite you to be part of it.
