Fluid balance, nervous system and magnesium – the underestimated importance of electrolytes

Hydration and electrolytes are the cornerstones of body health and functioning. While water is the primary fluid that keeps us alive, electrolytes ensure the proper electrical environment of our cells, fluid balance and muscle and nerve function. This means that consuming fluids with electrolytes can be beneficial in many cases – especially when the body loses fluid through sweating, intense training or heat.

🧠 What are electrolytes?

Electrolytes are ionic minerals that carry electrical charge when they dissolve in water. The main electrolytes in the body are sodium, potassium, calcium, chloride and magnesium. They help:

• maintain fluid balance,

• conduct nerve impulses,

• regulate muscle contractions (including heart muscle),

• stabilize the body’s pH level.

Without sufficient electrolytes, these processes cannot function efficiently – the body cannot properly transport water into and out of cells.

 

🧪 Why is magnesium important?

Magnesium is one of the electrolytes whose role is often underestimated, but it participates in many of the body’s biochemical reactions. For example:

• Magnesium is important for muscle relaxation and helps prevent cramps.

• It is associated with energy production and reduces fatigue.
• Additionally, magnesium supports nervous system function and helps maintain the proper balance of electrolytes in cells.

 

Electrolyte + vitamin water with magnesium 330 ml contains:

• water and electrolytes (including magnesium citrate, sodium chloride),

• vitamin C (known antioxidant),

• low sugar content flavor (2,5 g/100 ml) – which is significantly less than many sports drinks.

This combination can support:

✔ restoration of fluid and mineral balance after sweat loss,
✔ recovery after physical exertion,
✔ energy metabolism and general well-being thanks to vitamin C and magnesium.

💧 Electrolytes and magnesium – why might the body need them in everyday life too?

Electrolytes and fluid balance are often associated with sports or hot summer days. In reality, electrolyte levels in the body are affected by many everyday physiological and lifestyle-related factors that may not be immediately visible. The balance of electrolytes – including magnesium – is important for the normal functioning of the nervous system, muscles, heart and metabolism throughout life.

🧠 The role of electrolytes in the organism

Electrolytes (such as sodium, potassium, magnesium, calcium and chloride) are minerals that dissolve in water and conduct electrical signals. They are essential for:

• transmitting nerve impulses

• regulating muscle contractions and relaxation

• maintaining heart rhythm

• maintaining fluid and blood pressure balance

• cellular energy production (ATP synthesis)

⚠️ Electrolyte balance can be disrupted by factors other than heat and exercise

1️⃣ Daily stress and nervous system load

Chronic stress increases cortisol and adrenaline levels, which in turn accelerate magnesium excretion in urine. Magnesium has a calming effect on the nervous system, and its deficiency can worsen anxiety, sleep disorders and muscle tension.

📚 Reference:
Seelig, Consequences of magnesium deficiency on the enhancement of stress reactions, Journal of the American College of Nutrition, 1994

2️⃣ Consumption of coffee, alcohol and diuretics

• Caffeine and alcohol promote the excretion of fluids and electrolytes through the kidneys

• Certain medications (such as blood pressure medications, diuretics) can reduce sodium, potassium and magnesium levels

This means that even with adequate water intake, the mineral balance may be disrupted.

Whang et al., Magnesium depletion due to drugs, Archives of Internal Medicine, 1992

3️⃣ Digestive tract problems and absorption disorders

Diarrhea, irritable bowel syndrome (IBS), celiac disease or inflammatory bowel diseases can significantly reduce the absorption of electrolytes and minerals. In such situations, the body may need easily absorbed electrolytes in liquid form.

4️⃣ Inadequate or imbalanced nutrition

Modern nutrition often contains:

• processed foods (lots of sodium, little magnesium)

• few whole grain products, legumes and green vegetables

Studies show that a significant portion of the European population does not reach the recommended daily amount of magnesium.

EFSA Panel on Dietetic Products, Dietary Reference Values for magnesium, 2015

5️⃣ Age and hormonal changes

With increasing age:

• mineral absorption decreases

• medication use increases

• kidney function changes

Hormonal fluctuations (such as PMS, menopause) can also increase magnesium needs, as this mineral participates in muscle and nervous system regulation.

🥤 Electrolyte + vitamin water with magnesium as daily support

Electrolyte + vitamin water with magnesium (330 ml) can be a practical choice in situations where:

• fluid is consumed, but mineral levels may be low

• there is fatigue, muscle tension or concentration difficulties

• you want a low sugar alternative to sweet drinks

In addition to electrolytes, the drink contains vitamin C, which supports the immune system and helps reduce oxidative stress.
