THE BENEFITS
Complete hydration, not just water
Rehydration during effort

Rehydration

A high dose of sodium and potassium is crucial to offset losses from sweating (during exercise or in hot weather) and restore electrolyte balance. Drinking water is not always enough.
Muscle recovery

Recovery

The intake of magnesium, calcium, potassium and sodium helps prevent cramps and muscle fatigue and supports the proper functioning of the nervous system.
Why Cuure
The dosage the most complete in 1 tablet

Potassium

per tablet, i.e. 20% of the reference values

Sodium

in 2 forms: chloride and bicarbonate

Sugar

no sugar or synthetic sweeteners

K / Na / Ca ratio

designed for effort and heat
INGREDIENTS
A formula well dosed and well absorbed

Potassium chloride

The most concentrated mineral in the formula. Potassium contributes to normal muscle function and to the maintenance of normal blood pressure.

WHAT THE SCIENCE SAYS
What science says about electrolytes and hydration

HYDRATION

Sodium supports water retention during effort

The American College of Sports Medicine position stand recommends including sodium (0.5 to 0.7 g per litre) in rehydration drinks during efforts lasting more than an hour, to improve fluid retention.

MUSCLE FUNCTION

Potassium, magnesium and calcium

Potassium, magnesium and calcium contribute to normal muscle function; magnesium and potassium to the normal functioning of the nervous system. These are health claims authorised at European level.

ELECTROLYTE BALANCE

The recognised role of magnesium

Magnesium contributes to a normal electrolyte balance and to the reduction of fatigue, based on European scientific opinions.

FAQ

Your questions frequently asked

They regulate vital physiological functions, in particular: the distribution of water in and between cells (homeostasis), nerve conduction and muscle contractions, acid-base balance (blood pH), and the proper functioning of the kidneys and heart.

Electrolytes are electrically charged minerals (ions) dissolved in body fluids. The main ones are: sodium (Na+), which regulates water volume and blood pressure; potassium (K+), essential for muscle contraction and heart function; magnesium (Mg2+), a cofactor of many enzymatic reactions, involved in muscle and nerve relaxation; calcium (Ca2+), involved in muscle contraction and nerve transmission.

Our formula is 100% sugar-free and free of artificial sweeteners. Unlike many products on the market that use dextrose, glucose syrup or artificial sweeteners, we chose a pure formulation, with no calories or glycemic effect. You get effective hydration, with no compromise on the composition.

Yes, it is possible to over-hydrate: this is called hyponatremia. It happens when you drink large amounts of water without replacing electrolyte losses, especially sodium. Blood sodium drops, which can cause nausea, headaches, confusion, and even serious complications in extreme cases. That is why effective hydration relies not only on water, but also on an adequate intake of electrolytes, especially during intense activity, hot weather or excessive sweating.

The salty taste comes from sodium and potassium, two minerals essential for good hydration. Our formula contains the doses recommended by clinical studies, for real effectiveness. We chose not to add sugar, only a little stevia to soften it naturally. And if the taste seems too strong, feel free to dilute in more water.
