Composition of the lozenges
-
Magnesium
It reduces physical and cerebral fatigue and helps limit and reduce cramps. It also participates in the formation of teeth and bones, as well as maintaining their strength. Finally, it is beneficial against stress and anxiety. It is found, for example, in chocolate.
-
Potassium
It allows normal muscle and nerve function. It supports muscles to prevent cramps. It maintains the acid-base balance in the body inside the cells and helps maintain hydration of body cells. It is found for example in bananas.
-
Chloride
It aids in digestion and helps the body retain fluids efficiently. It stimulates brain function and contributes to general mental balance. It is found, for example, in olives.
-
Zinc
It allows the immune system to function properly and fights against premature aging of cells thanks to its strong antioxidant action. It is found, for example, in oysters.
-
Manganese
It protects cells against oxidative stress thanks to its antioxidant effect. It is also effective against fatigue and participates in bone formation (synthesis and renewal). It is found, for example, in hazelnuts.
-
Sodium chloride
Sodium is an essential ingredient, when combined with sugar in the right ratio. It speeds up the absorption of water into the bloodstream, replacing what your body loses through sweat. Additionally, salt retains water in muscle tissue while counteracting dehydration.
-
Dextrose
Dextrose is a form of glucose, a naturally occurring sugar compound found in our bodies. It is the most absorbable of all sugar compounds and enhances the absorption of our products into the bloodstream.
How does Hydratis work?
1- Passage of water through the intestinal barrier
Hydratis lozenges optimize the absorption of electrolytes and water in the intestine thanks to specific physiological mechanisms.
The absorption process is based on the synergistic action of sodium-glucose cotransporters (SGLT-1), located on the surface of intestinal cells (enterocytes). This transporter uses the energy of the sodium gradient to simultaneously bring sodium and glucose into the cells. This dual transport creates an osmotic gradient, thus attracting water to the cells, which promotes rapid and efficient absorption .
This mechanism is particularly crucial in cases of moderate dehydration, where the body needs to reabsorb more water and sodium to maintain fluid balance. Glucose, by increasing the osmotic pressure inside the cells, accelerates the absorption of water, thus improving the overall efficiency of the process . In parallel, glucose is used, while sodium is actively transported out of the cell by the Na+/K+-ATPase pump, allowing the process to continue uninterrupted.
2- After intestinal absorption
After absorption, water and electrolytes are rapidly transported through the bloodstream to the body's cells, where they play a key role in maintaining fluid and electrolyte balance. The Na+/K+-ATPase pump, present in the cell membrane, is essential for creating an electrochemical sodium gradient. This pump expels three sodium ions out of the cell while bringing in two potassium ions, generating an osmotic gradient.
This gradient draws water through specific channels called aquaporins, which allow rapid and controlled transport of water into the interior of cells. This mechanism is vital to ensure efficient intracellular hydration and to rapidly meet the water needs of cells, while maintaining their volume and optimal function. The pump also ensures the maintenance of the electrical potential of the cell membrane, essential for many cellular functions, while aquaporins facilitate the rapid adjustment of hydration according to changes in the internal environment.
Principle of osmolarity
What is this ?
Osmolarity is a measure of the total concentration of solutes dissolved in a fluid, such as blood or the water inside our cells. These solutes include electrolytes such as sodium , potassium , and chloride . Osmolarity is expressed in osmoles per liter (Osm/L) and is crucial in determining how water moves between different parts of the body.
Hypotonic drinks
Hypotonic drinks , such as those prepared with Hydratis lozenges , have a lower osmolarity than blood. This means that they contain a lower concentration of electrolytes and solutes . By consuming a hypotonic drink like Hydratis, water is more quickly absorbed by the intestine and is readily available to cells, allowing for rapid hydration without overloading the body with electrolytes.
How does it work?
When a hypotonic drink enters the intestine, its low osmolarity level facilitates the rapid passage of water into the blood, thus optimizing hydration without causing electrolyte imbalance.
Our product effectiveness studies
Swedish fit
To follow a scientific approach and see the impact of our tablets on people's hydration , we carry out various usage tests.
In a study of 19 participants , each participating in a weekly 45-minute sports session for three consecutive weeks . The participants were divided into three groups that changed every week: a group drinking 650 ml of spring water with Hydratis, a group drinking the same amount of spring water alone, and a control group drinking nothing.
Each participant was subjected to each condition (water + hydratis, water alone, nothing) in order to reduce inter-individual variability. Data were collected using a bioimpedance meter which is a precise device measuring body hydration, among others, of the subjects.
Results & Conclusion
Hydratis improves total water volume (+74 mL) versus a loss of 313 mL with 600 mL of water.
By using Hydratis, athletes increased their total water volume by 0.21%, while water alone causes a loss of 0.88%. That's a difference of more than 1% (see graph below) ! This may not seem like much, but for comparison, a loss of 5% of water is equivalent to “severe dehydration” (Source: Améli 2024).
The Hydratis scientific team is currently working on other study projects with partners from different backgrounds!
