Our Guayusa

Organic and fair trade.

Guayusa is a caffeinated Amazonian 'super-leaf' belonging to the holly species that contains a unique blend of polyphenol antioxidants and caffeine (~20% caffeine, 30% chlorogenic acids, 5% catechins). This blend gives Watt Water its unique energy, which keeps you uplifted/ focused and ready for action. Guayusa is also remarkably low in tannins which are responsible for the bitter taste found in most teas - giving it a sweet flavour profile.

Great tasting energy drink!

Healthy, environmentally conscious product and excellent customer service.


Love it!

So delicious!!

Love the peach flavor :) The tablets might be small but they pack a full cup of flavor! Was a great addition to my water and felt great in my workout following.

Steph P. (Papendrecht, The Netherlands)
Feeling focused!

I love energy drinks and have trouble working/studying without them, so of course I had to try these out! I picked the raspberry flavor and it tastes great :) The glass bottle design is really nice too. I'll be drinking these again!

Tom M. (Falmouth, United Kingdom)
Great stuff

I've been drinking watt water for a while now, and I'm really impressed. Each flavour tastes great (especially the raspberry), and it gives you a lot of energy too. all that from a tiny cube with no sugar in!




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 does Guayusa contribute to Watt Water's energy effects?

Guayusa's natural caffeine and L-theanine combination creates a synergistic effect. While caffeine promotes wakefulness, L-theanine balances stimulation, reducing jitters and promoting a smoother, sustained energy release.

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 20 trucks to transport the same amount of canned energy drinks. That's 20 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 81% reduction in CO2 emissions and >95% reduction in plastic (during transportation), or >99% reduction if compared to drinks that use plastic bottles.

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.
