Inside HydraTherm™
World's 1st proprietary three-layer hydration system. Designed for the moment, not the average....
The problem we solved.
Hydration isn't one thing. It's three. Most products solve one of them and call it hydraion. K3 doesn't.
The electrolyte layer. The hydration layer. The gut layer. All three, in every sachet, set to the moment. Deliver true physiological hydration.
Why sodium alone isn't a system.
Most electrolyte drinks solve one thing: replacing salt. That's the first layer. K3 starts there — and adds two more.
Because hydration isn't just what your body loses on the outside. It's what's happening inside your cells. And it's what's happening in your gut while you absorb everything you drink.
Three layers, not one. Set to the moment.
Three layers. One system.

The electrolyte layer.
Designed to put back what sweat takes out quickly.
The hydration layer.
Designed to keep fluid where it's needed, not just where it's drunk.
The gut layer.
Designed to keep the system calm and absorbing under load.
How it works
You drink. The electrolyte layer engages.
The hydration layer holds it where it matters.
The gut layer keeps the system absorbing — even under pressure.
Set to the moment.
Greatness starts before the first rep.
The system at its pre-session setting.
Greatness is the habit.

No proprietary blends hidden behind buzzwords. Just a system, built for the moment.
For coaches & practitioners.
What is HydraTherm™, in technical terms?
HydraTherm™ acts on three physiological processes behind effective hydration:
Replace — sodium-coupled fluid transport: the electrolyte profile that drives water uptake from the gut into circulation.
Hold — organic osmolyte-mediated cell volume regulation: osmolytes that help cells retain and stabilise fluid under stress.
Absorb — postbiotic-mediated barrier integrity support: gut support so the system works under real heat and effort.
What ingredient categories make up each layer?
Each layer is built from a defined category of functional ingredients:
Replace — electrolytes: the minerals lost in sweat, in a targeted profile.
Hold — osmolytes and amino acids: compounds that help the body retain and use fluid.
Absorb — a natural gut support preparation: gut support for uptake under heat and effort.
