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. • Clean taste that mixes easily. Nothing heavy. • Hydration that feels like it's working, not just sitting in your stomach. HOW TO USE When 30–60 minutes before training, competition, or an intense day How Mix 1 sachet in 500 ml of cold water. Shake or stir until dissolved. Best paired with Use Steady on lighter days. Add Reset after hard sessions for the full system. Best for Hard training sessions, heat, travel days, early starts, match days 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.
