We’re a small company doing big things

We created Protein2o as a crazy idea. We thought there must be a better way to consume the two nutrients most important to our bodies — water and protein – without a lot of unnecessary calories.

We’re proud to be a small but experienced, Chicago-based company dedicated to doing the right thing. Our mission seeks to improve people’s lives by providing great tasting drinks that promote a healthy, active lifestyle through the daily use of protein. When many large companies cut corners, we don’t. When other companies exaggerate their product benefits, we won’t.

We quite simply make low-calorie, great tasting protein water. And we have fun doing it! We hope you give us a try and enjoy a refreshing take on protein.
