We are redefining the way the world hydrates

Why sum?

sum. hydration was born from a simple observation: there is too much waste and not enough science in the beverage industry. Founded by a team of scientists, athletes, engineers, and environmentalists, we set out to create a hydration solution that would deliver personalized performance benefits without the negative environmental impact. After years of research and development, we created our Smart Cartridge system that allows for customizable hydration without any single use waste.

We follow the science.

At sum., we believe that hydration is not one-size-fits-all. Our formulations are based on extensive research in sports science, nutrition, and physiology to deliver optimal hydration for different needs and activities. Our team of scientists and nutritionists have developed precise combinations of electrolytes, natural caffeine, and flavors that work together to enhance performance, recovery, and overall well-being. Every ingredient in our formulations are carefully selected for their bioavailability, efficacy, and safety, ensuring that you get the most out of your hydration experience.

We're committed to sustainability.

You shouldn't have to choose between being hydrated and the health of our planet. With sum., you don't have to. Our distribution process produces zero single use waste and we are committed to an absolute zero waste delivery system within the next two years.

Water is a human right.

We believe this wholeheartedly. That's why we supply clean, cold, healthy water at absolutely no charge. It's also why we're committed to creating solutions in communities where people struggle with access to water.

What's in, or not in, our products?

We use absolutely no preservatives, dyes, or sugar. We believe it's incredibly important for you to know what you're putting into your body. When you purchase our product, we view this as a very serious trust. We will always disclose the ingredients, in their entirety whether regulatory agencies require us to or not.
