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 great tasting protein water. And we have fun doing it! We hope you give us a try and enjoy a refreshing take on protein.

What We Make

So easy, so delicious, and so effective, it’ll have you wondering...
how is this possible?

Protein2o comes in 11 flavors (5 with 15 grams of protein, 4 with 10 grams of protein and 2 +Energy flavors with 15 grams of protein and 125 milligrams of caffeine). Our waters have 60-70 calories per bottle and 110% of essential amino acids.
