K3 Loaded

Start before the first rep.

Pre-session hydration, powered by Hydratherm technology. The worlds 1st 3 layer hydration system. Zero Sugar

Before training. Before the day.

Most electrolytes replace what you've already lost. Loaded is crafted for what comes next — so you start the session topped up, not catching up.

The electrolyte profile has been deliberately formulated for the pre-session window. Drawing on established exercise physiology, we have calibrated sodium, potassium, magnesium, calcium and chloride at ratios designed to support fluid balance at the point of highest physiological demand — before intensity begins. Sodium leads the formulation as the primary driver of fluid uptake, supported by potassium and magnesium to address the electrolyte relationships most relevant to muscular function during exercise. The result is an electrolyte system built not to replace what you have already lost, but to prepare the physiological environment before the first rep, the first kilometre, or the first round.

Electrolytes + HydraTherm™. That's the difference.

WHAT YOU'LL NOTICE

• You start the session feeling ready — not flat.

• No sugar spike before you move. No crash mid-session.

How HydraTherm™ works

Most hydration products are built on one layer: electrolytes. Electrolytes replace what you lose in sweat. That matters. But at K3 we believe serious athletes need more than replacement.

HydraTherm™ is K3's proprietary three-layer hydration system, crafted to go beyond electrolytes:

Layer	Name	What it's designed to do
Layer 1	Replace	Targeted electrolytes for the pre-session moment — sodium, potassium, magnesium, calcium, chloride.
Layer 2	Hold + Use	A proprietary amino-osmolyte layer, designed around sodium-linked fluid uptake pathways to support water handling at the cellular level.
Layer 3	Absorb	A postbiotic gut layer, built around the reality that heat and intensity can challenge gut barrier reliability — when hydration needs to be at its most dependable.
