When should you take electrolytes? The complete guide to optimal hydration

Quand faut-il prendre des électrolytes ? Le guide complet pour une hydratation optimale

Drinking water is essential for your health , energy and daily well-being .
But that 's not always enough. For your cells to function properly, your body also needs minerals, including electrolytes .

Often underestimated, they play a key role in the proper functioning of your bodily functions , especially during physical exertion , high temperatures or episodes of dehydration .

In this guide, we explain when to take electrolytes , what they are used for , and in what situations their consumption can be beneficial , or even necessary .

Electrolytes: what are they?

Definition and role in the organism

Electrolytes are electrically charged minerals present in your bodily fluids ( blood , sweat , urine ).

They enable the proper functioning of cells , muscle contraction , blood pressure regulation , and nerve transmission .

The main electrolytes: sodium, potassium, magnesium, calcium

Here is a list of the main electrolytes:

  • Sodium : it retains water in the body, regulates blood pressure and allows the transmission of nerve impulses .
  • Potassium : it supports muscle activity and blood pH .
  • Magnesium : it promotes muscle relaxation and recovery .
  • Calcium : it plays a role in muscle contraction , coagulation , bone strength and the activation of certain metabolic enzymes .
  • Chloride : it helps maintain blood acidity and osmotic pressure , in addition to sodium .

Natural sources vs. electrolyte supplements

You can find these elements in various foods : bananas , coconut water , green vegetables , lightly brewed teas , lemons , or certain fruits rich in potassium, magnesium, or calcium . However, these intakes may be insufficient in some situations .

Electrolyte drinks , tablets or rehydration sachets These can then quickly compensate for excessive loss . It is advisable to compare prices , reviews , ingredients , and formats before choosing the most suitable drink.

The lozenges Hydratis are designed to promote optimal hydration and a balanced mineral intake . They are distinguished by their ease of use , as they simply need to be dissolved in water .

Their pleasant taste , neutral or fruity , makes hydration both easy and enjoyable .

The benefits of electrolytes

Cellular hydration and fluid balance

Electrolytes ensure optimal hydration by maintaining the correct distribution of fluids between your cells and your bloodstream .

After intense physical activity or a prolonged race , their contribution then becomes indispensable .

Fortified drinks or dissolving tablets therefore allow for more effectivehydration than simply drinking water .

Without them, water alone may not be enough to properly hydrate your body after significant fluid loss .

Muscle function and recovery

They are very useful for prevent muscle contractions , reduce post-exercise pain and promote good recovery .

Chloride , magnesium , and potassium allow muscle fibers to function without imbalances , thus limiting the occurrence of cramps .

Proper electrolyte management also contributes to more stable muscle performance .

Support for nerve and cardiovascular functions

A good electrolyte balance , particularly in sodium and potassium , is essential for the normal functioning of the nervous system and the heart .

A deficiency in these minerals can cause a drop in blood pressure , fatigue or dizziness .

Maintaining this balance requires a diet adapted to your needs and lifestyle .

When should I take electrolytes?

1. During intense or prolonged physical activity

During prolonged exertion ( running , cycling , hiking , endurance sports ), your body loses a lot of water and minerals through sweat (especially sodium!).

Drinking only water can lead to a dilution of sodium , thus causing hyponatremia .

An electrolyte drink to allow you to maintain your performance and fill this gap .

2. In hot weather or in case of excessive perspiration

During the summer months , the body sweats more to regulate its temperature .

This loss of water is also accompanied by a loss of essential minerals such as sodium , potassium , and magnesium .

Without compensation , this can cause fatigue , cramps or a drop in energy .

Hydration containing electrolytes then helps to restore balance and stay in shape even in the heat .

3. In cases of dehydration related to illness (fever, vomiting, diarrhea)

Fever or gastrointestinal episodes cause a rapid loss of fluids and minerals .

In this case, the World Health Organization (WHO) recommends oral rehydration solutions (ORS) containing sodium , potassium , glucose , and an alkalizing agent such as bicarbonate or citrate . These solutions are generally recommended for infants .

These solutions help to compensate for water and electrolyte losses , and to correct metabolic acidosis, often associated with dehydration .

4. During periods of stress, intense fatigue, or digestive problems

Chronic stress , fatigue or an unbalanced diet can disrupt the electrolyte balance of your body , as they influence perspiration , digestion and the absorption of essential minerals .

A one-off course of electrolytes can then offer quick support .

5. In the case of a ketogenic or low-carbohydrate diet

Low-carbohydrate diets induce increased loss of sodium and potassium .

Indeed, reducing carbohydrates decreases glycogen reserves , which retain water and electrolytes , leading to their loss .

An electrolyte supplement can thus prevent the symptoms of keto flu ( dizziness , nausea , muscle tension ).

How do you know if you need electrolytes?

Signs of an imbalance: cramps, headaches, fatigue, dizziness

Be aware that symptoms such as cramps , headaches , unusual fatigue , dizziness , or rapid weight loss due to sweating may signal a deficiency .

If you experience any of these signs , it may be necessary to consult a healthcare professional , rest , and stay hydrated . and to restore your electrolyte balance quickly .

When water alone is no longer enough

If you drink regularly but still experience fatigue or pain , your cells may be deficient in electrolytes . This often happens after prolonged exertion or in intense heat .

In this case, it may be helpful to consume drinks or foods containing electrolytes to restore your body 's balance .


Is it possible to consume too many electrolytes?

The risks of excess (particularly of sodium or potassium)

Chronic excess can cause adverse effects . Indeed, too much sodium It can lead to water retention , weight gain , or high blood pressure . Excess potassium can affect heart rhythm . Therefore, it is important to adhere to the recommended dosages .

If you are taking Hydratis tablets , we recommend adhering to the recommended daily dosage to maintain a healthy electrolyte balance and avoid excess . If you have any questions, we recommend consulting your doctor.

Should it be taken every day?

No. A daily dose is not necessary for everyone.

It depends on your diet , physical activity , and exposure to heat . In some cases, such as during travel or illness, their consumption can also be beneficial.

If your diet is varied and you do not sweat excessively , natural hydration is sufficient.

Dosage and recommendations according to lifestyle

  • Regular athletes: consume electrolytes during or just after exercise to compensate for losses due to perspiration and promote recovery.
  • Sedentary people: occasional supplementation may be useful, particularly in cases of fever, diarrhea or periods of intense stress.
  • Diet low in fruits and vegetables: A light electrolyte supplement helps maintain a good daily mineral balance.
  • Hot climate: prioritize hydration containing electrolytes during periods of high heat to prevent fatigue and dehydration.

5 common misconceptions about electrolytes

"Drinking water is always enough."

That's false. In cases of dehydration , water alone does not compensate for mineral losses .

"All sports drinks are effective."

Some are too sugary or low in minerals . It is essential to check their composition and choose them according to your needs .

"You need to take electrolytes before each session."

No. Normally, electrolytes are already present in your body before exercise . They become useful before , during , or after exercise , especially if the activity lasts more than an hour or takes place in high heat , because you lose them through sweat .

"They are reserved exclusively for athletes."

False. Anyone exposed to fluid loss can benefit: children , adults , the elderly or the sick .

"Electrolytes cause bloating or weight gain."

No, except in cases of excessive sodium consumption over the long term . When used in moderation , they do not cause weight gain .
