Sparkling functional water
Hydration that
actually does something.
Real electrolytes, a clean lift of focus and zero sugar crash. Pick a flavour, watch the can change, and find the one your afternoon has been missing.
- 0g added sugar
- 5 electrolytes
- 200mg L-theanine
Yuzu Citrus, sharp and bright. The morning reset.
Why it works
Function you can feel, not a label you have to trust.
-
Real electrolytes
Sodium, potassium, magnesium, calcium and chloride in the ratio your body actually uses, so a single can rehydrates faster than plain water.
-
Clean, calm focus
200mg of L-theanine paired with a measured 60mg of green-tea caffeine. The alert-but-steady state, without the wired feeling or the 3pm dip.
-
No sugar, no crash
Zero added sugar and four calories a can. Sweetness comes from a whisper of monk fruit, so the lift you get is real and the comedown does not exist.
-
Adaptogen support
A daily dose of ashwagandha and Siberian ginseng helps your body handle a heavy day with a bit more grace. Subtle by design, not a stunt.
When to drink
One can, the right moment.
Flow is not an energy drink you slam at the gym door. It is a small, reliable habit for the parts of the day that ask the most of you.

The morning reset
Open one before the inbox does. Rehydrate overnight losses and start the day clear rather than scrambling for the kettle.

The afternoon hold
The moment the room goes flat. This is what Flow was built for, the steady focus that carries you through to the end of the day.

The switch off
A caffeine-light flavour (reach for Wild Berry) to unwind without going to sleep on the sofa at half six.

Why we made it
We were tired of choosing between a treat and a tonic.
The fridge always offered the same bad deal. Something sweet that lifted you for an hour and dropped you for three. Or something earnest in a beige can that did you good and tasted like penance. Nothing that managed both at once.
So we built the thing we kept looking for. Proper, measured function: a full electrolyte profile, a calm-focus pairing of L-theanine and a half-coffee of green-tea caffeine, a daily dose of adaptogens. Then we made it taste like a drink you would reach for even if it did nothing at all.
It is brewed in small batches in Yorkshire, the recipe is printed in full on every can, and the only thing we have ever hidden is how simple it really is. Six ingredients, measured properly, in water worth drinking.

I replaced my second flat white with the Electric Lime and the 3pm slump genuinely went away. I did not expect a fizzy water to fix that.

It tastes like a treat and reads like a supplement. Yuzu Citrus is the only thing in the fridge my flatmate and I both fight over.

Bought a case to try, now on a subscription. The focus is the real thing, calm rather than buzzy, and there is no horrible crash afterwards.

Good questions
The things people ask before the first case.
Is it actually any good for me, or is that marketing?
Both halves are real. A full five-mineral electrolyte profile rehydrates you faster than water, and the L-theanine and green-tea caffeine pairing is a well-studied combination for calm focus. The amounts are printed on the can so you can check them against the science yourself.
How much caffeine is in a can?
Sixty milligrams of green-tea caffeine, roughly half a cup of coffee. Enough to lift the afternoon, not enough to keep you up. Wild Berry is the gentlest if you are caffeine sensitive.
Will it taste like medicine?
No. We started with the taste and worked the function in around it. The sweetness is a whisper of monk fruit, four calories a can, and people tend to fight over the last one in the fridge.
Can I mix flavours in a case?
Yes. The Starter Case is mixed by default so you can find your one. After that, build single-flavour cases or keep the mix, whatever suits.
How does the subscription work?
Pick a frequency, save fifteen per cent, and we deliver carbon neutral across the UK and Ireland. Pause or cancel any time from your account in two taps. No phone calls, no retention scripts.
