What is Watt Water?

Watt Water is an energy drink that comes in a cube format which, when added to water, transforms into a delicious energy drink. It's designed to provide sustained energy and focus. Its active ingredient is Guayusa which provides a smooth & natural energy experience without the jitters and crashes of traditional energy drinks.

How is it so affordable?

We are made as a more economical & healthier at-home (and simultaneously on-the-go) alternative for people who love their daily energy drinks or coffee.

Because we don't use cans we avoid a lot of costs & overheads, which means that we can put all our energy and funding into sourcing the best possible ingredients and flavours.

How does Guayusa contribute to Watt Water's energy effects?

Guayusa has unique benefits. Unlike caffeine on its own, guayusa provides sustained energy without jitters or crashes thanks to its unique chlorogenic acid profile which enables a gradual caffeine release, promoting lasting smoother, sustained energy and focus.

Serotonin (the "happy hormone") is elevated to levels that are 2-3x higher than those from coffee. Higher serotonin levels can positively influence decision-making by improving mood, reducing stress, enhancing cognitive function, boosting confidence, regulating emotions, and facilitating better social behaviour, all leading to better choices.

What makes Watt Water eco-friendly?

A dry cube format, rather than shipping cans or bottles, is ultimately more energy efficient due primarily to size and number of drinks that are in a pack. Think of it this way: while it takes 1 truck to transport a million Watt Water drinks, you need 58 trucks to transport the same amount of canned energy drinks. That's 58 times more CO2 emissions. Also, though cans themselves aren't made of plastic, plastic is wrapped around each shipping pallet and each individual 12-can tray when transported to stores or warehouses.

As a result, using cubes like this leads to 98% reduction in CO2 emissions and 99% reduction in plastic.

Our Guayusa is organically farmed and fair trade. Our packaging is a single material plastic that can be recycled an unlimited amount of times.

Is it really sugar-free and without calories?

Absolutely! Watt Water is completely sugar-free and has zero calories. We understand the importance of offering a healthier hydration option, and that's why we've crafted Watt Water to provide the refreshing taste you love without any added sugars or unwanted calories. Our focus is on delivering a clean and pure hydration experience that aligns with your health and wellness goals.

Is it vegan?

Yes! Watt Water is completely vegan.
