A quoi servent les boissons isotoniques et comment ca marche ?

What are isotonic drinks used for and how do they work?

What is an isotonic drink ?

A drink is said to be isotonic when it contains the same concentration of particles as blood. The osmolarity being between 270 and 330 mOsml/Litre. It is recalled that the osmolarity is the concentration of the active particles contained in a solution expressed in osmoles or in milliosmoles per liter of solvent.

These are drinks dedicated to athletes during their effort and are energizing thanks to . It is advisable for athletes to take an isotonic drink or a slightly hypotonic drink. Above all, hypertonic drinks are not recommended.

On the other hand, we have hypotonic solutions: The concentration of particles is lower than that of blood. The drink is very dilute and will promote rehydration at the expense of nutrient absorption.

Conversely, we have hypertonic solutions: the concentration of particles is greater than that of blood. The drink is very concentrated and lengthens the speed of digestion and therefore limits rehydration. You can get cramps or heartburn here.

For more details, find our blog: What is an isotonic drink?

What are the purposes of an isotonic drink?

It is therefore understood that the isotonic drink will have the effect of promoting the intake of water, minerals and nutrients to promote the exchange of what the body uses during exercise. The components of this "energy" drink can therefore be quickly absorbed and digested by the body.

An isotonic drink is easily absorbed and will quickly leave the stomach for optimal efficiency and digestive comfort.

When should you take an exercise drink?

They can be taken when practicing sports, these drinks will be more useful for endurance sports which cause a greater risk of dehydration due to sweating. The human body can lose more than two liters of sweat per hour. Without a drink, the body will become dehydrated.

Remember that Hydratis lozenges contain sodium, glucose and water, they are isotonic drinks. Glucose will be used to provide energy to the muscle during an effort with sodium, it will accelerate the absorption of water into the bloodstream by exchanging what the body loses through perspiration.

In any case, the body needs water and it is therefore necessary to drink, to hydrate regularly.

For an effort of two hours or more, it is advisable to consume a carbohydrate drink. It must be isotonic and contain sodium, vitamin B1. Vitamin B1 is involved, as a co-enzyme, in the metabolism and absorption of carbohydrates, lipids and proteins. It will therefore play its role as an energy producer.

For a longer effort, we still recommend isotonic drinks. They must contain sodium, potassium and magnesium. They will also have vitamins B1, B2 and B6. Vitamin B2 is involved in the metabolism of carbohydrates, lipids and proteins. It will release energy by the oxidation of glucose. Vitamin B6 plays a role in the renewal of red blood cells, the functioning of the immune system and the production of hormones (serotonin, dopamine, adrenaline, noradrenaline).

What are isotonic drinks?

Specially designed for the rehydration of the body Hydratis increases the osmolarity of your drink to make it ultra-hydrating while providing the electrolytes necessary to replace those lost during exercise through perspiration.

You can also make your homemade isotonic drink: dissolve sugar in a solution of green tea, lemon or vanilla, add a small pinch of salt and top up with water. Leave to cool and the drink is ready. It should be consumed within 24 hours.

Hydratis drink

With the Hydratis solution you have a quality isotonic drink ready to use! Dilute two Hydratis lozenges in a glass of water to create an isotonic drink enriched with minerals and trace elements. The drink helps to replace the electrolytes lost during exercise and thanks to magnesium and potassium to recover muscle more easily as well as to fight against oxidative stress of cells thanks to zinc and manganese. Hydratis is used in many situations where the body's water needs increase, such as after alcohol consumption , during hot weather and of course during and after physical exertion.

Hydratis is available in pharmacies , on Santé Discount and on Décathlon.fr
