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 is between 270 and 330 mOsml/Litre. It should be remembered that osmolarity is the concentration of active particles contained in a solution expressed in osmoles or milliosmoles per litre of solvent.

These are drinks dedicated to athletes during their effort and are energizing. It is recommended for athletes to take an isotonic drink or a slightly hypotonic drink. Hypertonic drinks are especially not recommended.

On the other hand, there are hypotonic solutions: The concentration of particles is less important than that of blood. The drink is very diluted and will promote rehydration to the disadvantage of the absorption of nutrients.

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

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 to take a sports drink?

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

We remind you that Hydratis tablets 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 in the bloodstream by exchanging what the body loses through sweating.

In any case, the body needs water and so it is necessary to drink and 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 and 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, isotonic drinks are again recommended. 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 body rehydration, Hydratis increases the osmolarity of your drink to make it ultra-hydrating while providing the electrolytes needed to replace those lost during exercise through perspiration.

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

Hydratis drink

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

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