Hydratis, how does it work?

It's not magic, it's science.
We tell you everything here.

Dehydration

[feminine noun]

This corresponds to a lack of water and mineral salts (called electrolytes) in the body, which are essential for the proper functioning of the organism. Dehydration occurs when excessive water loss is not compensated. It affects up to 78% of French people (IFOP study for Hydratis, April 2025) .

What are the main causes of dehydration?

Forgetting to drink

Physical effort

high heat

Alcohol consumption

Episode of diarrhea or vomiting

Excessive sweating

In our daily activities, our bodies use water and minerals to keep us in tip-top shape. That's why it's essential to stay hydrated throughout the day. Even forgetting to drink for a few hours can lead to mild dehydration.

Did you know that it's recommended to drink 1.5 liters of water per day for women and 2 liters for men? Yes, because when water and mineral losses are excessive and not compensated for by intake, dehydration is a threat.

Water is life, as the other one would say.

And it's true. Especially when you consider that our body is made up of about 60% water. Even when we're slightly dehydrated, we quickly see the following:

signs of fatigue
lack of energy
feeling of thirst
less frequent and darker urine
dizziness and vertigo

And for good reason, hydration fulfills vital functions.

It helps ensure the proper functioning of our brain, which is made up of 75% water.
It helps waste to be evacuated
It helps regulate body temperature
It lubricates our joints to facilitate our flexibility and our movements.
If it is insufficient, it slows blood flow and reduces the supply of oxygen and minerals, essential to the muscles and the brain.

Hydratis, science at the service of your thirst

Water is essential, but its absorption in the body is not always optimal or sufficient to maintain good hydration. It all comes down to electrolyte balance.

Shall we explain?

Electrolytes are minerals, found in water, fruits, vegetables, and other everyday foods, that enable the body to perform several essential functions. Sodium, for example, is an electrolyte that plays an important role in regulating blood pressure and retaining water in the body. Potassium, on the other hand, contributes to the body's acid-base balance and proper muscle function. Absorbing these electrolytes in the right concentrations helps achieve what is called osmotic balance, which is the proper distribution of water between the inside and outside of cells.
Conversely, if all of these minerals are not present in sufficient quantity, we speak of an electrolytic imbalance which can lead to poor absorption of water and therefore dehydration.

Knowing this, and surrounding themselves with scientists and health professionals, Théo Heude and Jérémy Boué, the founders of Hydratis, have developed a unique formula to create an effective, healthy and practical solution to improve our hydration.

How it works ?

Since the 1960s and 1970s, ORS has been used as a rapid and effective response to dehydration, particularly in infants and children. Recognized and recommended by the World Health Organization (WHO), they are based on a magic equation: a mixture of water, electrolytes, and glucose. This combination maximizes the body's absorption of water and allows for rapid action in the event of significant water loss. At Hydratis, we have taken inspiration from this principle, adapting it to each individual's daily needs and adding trace elements with antioxidant properties that support the proper functioning of the immune system.

Sodium + Potassium + Magnesium:

the optimum association!

Each plays a complementary role in fluid balance and muscle activity. Sodium helps maintain hydration, while potassium and magnesium support nerve and muscle function, helping to limit fatigue and cramps during exercise.

Glucose, in small doses

With sodium, they make a pair.

Combined, they activate a specific, essential transporter that accelerates the absorption of water into the body. When taken in very small doses, this prevents any blood sugar spikes and unnecessary sugar absorption.

Do the maximum, without the unnecessary

In addition to essential minerals, we've selected and incorporated complementary nutrients like zinc (to support immunity) and manganese (an antioxidant and ally for bone health). All this without any artificial colors or anything superfluous.

Why is Hydratis really different?

A hydration solution, not a soda

At Hydratis, we precisely dose the necessary amount of sugar (according to EFSA* recommendations) to achieve the perfect electrolyte/glucose ratio, and trigger the co-transport of water and sodium in the intestine.
Result: rapid hydration, not a sugar shot.

A formula validated by a scientific committee

Nutrition and health experts ensure that each ingredient serves a clear purpose. Nothing is left to chance.

For all occasions in life!

Hydratis everywhere, all the time! To prevent the risk of dehydration at any time, Hydratis is your ally to recharge your batteries and start again stronger.

1 formula, 10 flavors!

Because what's good for our health should also taste good, Hydratis combines science and flavor. Our teams have developed 10 different flavors, from the most classic to the most original. From peach to lemon, including pineapple and coconut, our effervescent tablets create non-sparkling drinks with a natural, light taste that's never sickening.
