Energy drinks based on mineral salts are a cornerstone of sport and fitness, offering valuable support for optimising athletic performance.
People who take part in energy-demanding activities that go on for long periods, in particular, lose a large amount of fluid, with a resulting drop in sporting performance.
We should always bear in mind that dehydration is the leading cause of tiredness (just 2% dehydration is enough), which is why proper supplementation becomes essential.
Let's find out together what makes these drinks so effective by taking a close look at their main ingredients: mineral salts and carbohydrates.
Hypovolaemia and Hypertonicity
Fluid intake is driven by two main physiological mechanisms: hypovolaemia and hypertonicity of the blood.
The thirst caused by hypovolaemia, called volumetric thirst, is regulated by antidiuretic hormone (ADH), which monitors blood volume and concentration. When blood volume falls and salt concentration rises, we feel the need to hydrate.
The other trigger for thirst is hypertonicity of the blood, detected by the organum vasculosum of the lamina terminalis (OVLT). When the blood becomes hypertonic, water leaves the cells through osmosis, and the body is prompted to drink water to counter dehydration.
During intense physical activity or exposure to high temperatures, such as in the summer months, it is essential to maintain an adequate level of hydration in order to optimise sporting performance and help replace the fluids lost through sweating.
Water and Hydration
The human body uses fluid loss as a basic natural mechanism for keeping body temperature constant in conditions where this balance is put under strain.
Keeping the water and electrolyte balance constant is vitally important for all the functions regulated by minerals that are essential to the body, such as heart function, the conduction of nerve impulses, kidney function, and voluntary and involuntary muscle contraction, with knock-on effects on breathing and mobility.
Drinking water alone, especially in large quantities and in the face of heavy sweat losses, could even be counterproductive, greatly diluting the mineral salts remaining in the body, which would then have to cope with an electrolyte concentration even lower than it had before the water was taken in. The result would be to trigger precisely the chain of adverse events that, paradoxically, we wanted to avoid at the end of our physical activity.
Sodium, Potassium and Magnesium
Sodium, potassium and magnesium are all electrolytes essential for the proper functioning of the human body, but they differ in their roles and physiological functions.
Sodium is involved in regulating water balance, transmitting nerve impulses and maintaining osmotic pressure. During physical activity, sweating can cause a significant loss of sodium, which can lead to dehydration and muscle cramps if it is not adequately replaced.
Potassium and magnesium are two key minerals for maintaining the body's balance and function during physical activity. Potassium supports cellular hydration and muscle contraction, while magnesium is involved in energy metabolism and neuromuscular regulation.
While sodium is crucial for water balance and the transmission of nerve impulses, potassium is essential for muscle function and magnesium supports a wide range of biochemical processes in the body. All three are important for athletes and active people, and appropriate supplementation can help improve performance and support recovery.
Carbohydrates
Energy drinks mainly contain simple carbohydrates such as glucose, fructose or maltodextrins. These sugars provide a rapid source of energy during physical activity.
What is the difference between an isotonic, hypotonic and hypertonic drink?
This is very important to know in order to prepare your energy drink and make the best use of the mineral salt supplement you have bought.
The tonicity (osmolarity) of a solution is determined by the number of charged particles dissolved in it.
The osmolarity of blood is about 300 mOsmol/litre, so a drink is hypotonic, isotonic or hypertonic if its osmolarity is respectively lower than, equal to or higher than 300 mOsmol/litre.
From a physiological point of view, whether it makes sense to use a drink with a given osmolarity depends on the goal:
Look for the nutrition table on the label and check, if stated, the osmolarity of the powdered salt solution you have bought.
Isotonic Drinks
Isotonic drinks are a popular choice among athletes in many disciplines, particularly cyclists and triathletes, because they provide a rapid supply of carbohydrates and mineral salts during exercise. Thanks to their balanced formulation, these drinks are quickly absorbed by the body, offering immediate support for athletic performance.
Mineral Salts in Physical Activity
During intense physical exertion, the body loses important mineral salts through sweat. Mineral salt supplements are a quick and practical way to replace these vital nutrients, helping to maintain optimal hydration and performance during sporting activity, whatever the sport.
What are the 3 golden rules?
In conclusion, energy drinks based on mineral salts and carbohydrates are a valuable tool for optimising athletic performance and helping you reach your sporting goals.

The osmolarity of blood is about 300 mOsmol/litre, so a drink is hypotonic, isotonic or hypertonic if its osmolarity is respectively lower than, equal to or higher than 300 mOsmol/litre.
From a physiological point of view, whether it makes sense to use a drink with a given osmolarity depends on the goal:
- rehydrating effect (maximum water absorption) = hypotonic drink (ISODRINK < 30 g per 500 ml);
- hydrating / energy effect = isotonic drink (ISODRINK = 30 g per 500 ml);
- energy effect = hypertonic drink (ISODRINK > 30 g per 500 ml). All hypertonic drinks should be taken in small sips spread out over time to avoid the risk of laxative effects.
Solutions with a concentration lower than that of blood, about 300 mOsmol/litre, are useful for hydration; isotonic solutions, meaning those with the same concentration as blood, provide both a hydrating and an energising effect by facilitating the exchange of substances between the solution and our blood; hypertonic solutions, on the other hand, are taken solely for energy.
Overdoing the concentration of the solution can lead to problems linked to poor gastrointestinal absorption of the substance and related side effects such as nausea and reflux or diarrhoea.

Mineral Salts in Physical Activity
During intense physical exertion, the body loses important mineral salts through sweat. Mineral salt supplements are a quick and practical way to replace these vital nutrients, helping to maintain optimal hydration and performance during sporting activity, whatever the sport.
What are the 3 golden rules?
- First of all, drink at regular intervals, before you feel thirsty. This applies especially to people who play sport, as the feeling of thirst is an unmistakable signal that our body is already "suffering" and needs to take in fluids.
- Pay attention to osmolarity! It is a little-known concept but a vitally important one. It indicates the concentration of a solution and therefore how well our body can absorb it. It is essential! Let's take an example to make the idea clear: oil and water are both liquids, but they do not mix; there is no "communication" between them. This happens because the density of the two liquids is different, and specifically oil has a lower density than water. The same applies to mineral salts, blood and osmolarity: to be compatible with our body and easily absorbed into the plasma, a salt solution must have a very specific osmolarity, which can range between 200 and 330 mOsm/kg H20. So always make sure you check this figure on the label.
- Carbohydrates, especially for people who do physical activity, are an indispensable source of energy that can make the difference under exertion. Their presence is therefore essential for having energy.
In conclusion, energy drinks based on mineral salts and carbohydrates are a valuable tool for optimising athletic performance and helping you reach your sporting goals.
