Amazing product, so convenient. Perfect
"Amazing product, so convenient. Perfect compliment to a busy work and training schedulle. Quality and tast much better than cheaper alternatives."
A hard, hot or busy hour drains 500 to 700mg of sodium. Most sachets give you 200 to 300. This closes the gap.
Sodium is the electrolyte you lose most through sweat. It drives fluid absorption and retention, keeps your electrolyte balance steady, and helps your body hold the water you drink instead of passing it straight through. Getting enough is what helps you stay hydrated, hold performance, and avoid the cramps that come with running low.
Potassium works alongside sodium to maintain normal fluid balance, nerve signals and muscle contractions. It also helps balance out sodium, so the two together keep your hydration steady rather than swinging in one direction.
Magnesium supports normal muscle function, the nervous system, and energy production, and contributes to reducing tiredness and fatigue. It helps move water where your body needs it, which matters for muscle function, energy and recovery.

Science-backed hydration formula
You sweat when you train. You also sweat on the commute, in the heat, and halfway through a long day. Cadence is dosed for all of it.

500mg sodium, 200mg potassium, 20mg magnesium, zero sugar. The electrolytes you lose, dosed to match.
Water replaces the fluid, not the sodium you sweat out. This does both, so you actually stay hydrated instead of just topping up.
First thing to start hydrated, before or during training, or any day you know is going to be a long one.
Mix with about 500ml of still water.
