Are conventional electrolyte drinks healthy?

While most commercial sports drinks provide electrolytes such as sodium, potassium, magnesium, and calcium, they also tend to be high in sugar and caffeine and often contain artificial ingredients. 

High consumption of pre-mixed isotonic electrolyte drinks is associated with weight gain and can exacerbate dehydration as a result of their high caffeine content, which triggers increased urination and fluid loss.    

A study published in Nutrients confirms the adverse health effects of traditional sports drinks and concludes that individuals who regularly consume sugar-sweetened electrolyte beverages are at increased risk of excessive weight, inadequate hydration status, and dental issues. 

Watch the video below to find out why sports drinks can cause dehydration and weight gain. 

How to choose a healthy electrolyte drink

Electrolytes are essential minerals that regulate various physiological functions, and incorporating electrolyte drinks into your daily routine is an excellent way to maintain optimal electrolyte levels and promote a healthy body.

Sodium and potassium are crucial electrolytes that regulate fluid balance and facilitate the transport of water into and out of cells. 

“Many people consume too much table salt and already have a high sodium intake,” explains Dr. Berg. “It’s important to ensure adequate potassium levels to balance the body’s fluid levels and counteract sodium’s water-retaining properties.”     

The body requires around 4,700 milligrams of potassium per day. However, according to evidence published in Clinical Chemistry, most people don’t consume enough electrolyte-rich foods to meet their daily potassium needs.  

To promote balanced electrolyte levels, it’s best to make your own electrolyte drink using a sugar-free electrolyte powder that contains at least 1,000 milligrams of potassium and around 40 milligrams of sodium per serving.

Maintaining a balanced potassium-to-sodium ratio promotes optimal hydration and helps maintain healthy blood pressure and heart function. 

It’s widely believed that watermelon juice and other fruit juices are good electrolyte sources. Unfortunately, fruit juices are high in sugar, making them unsuitable beverages to replace lost electrolytes.

5 health benefits of electrolyte drinks

Using an electrolyte powder to make electrolyte-infused water is an excellent alternative to pre-mixed sports drinks that can contain as much as 25 grams of sugar per serving. 

While it’s well known that replacing electrolytes helps maintain fluid and electrolyte balance, drinking electrolyte water offers remarkable health benefits beyond just regulating fluid levels.

Here are five reasons why you should replace electrolytes.  

1. More energy

Sodium and potassium generate a small electrical charge within cells, which is crucial for producing adenosine triphosphate (ATP).

ATP serves as the body’s primary energy currency, and a study published in Function found that potassium enhances the activity of ATP synthase, an enzyme that controls cellular energy production and regulates energy reserves. 

2. Lower risk of heart disease

Electrolytes maintain the body’s fluid balance, which determines blood volume and influences blood pressure.

Electrolyte imbalances, such as high sodium levels in combination with low potassium status, can trigger water retention and lead to increased blood pressure, a primary risk factor for heart disease. 

Potassium also promotes the relaxation of blood vessels, which is linked to healthy blood pressure, and adequate potassium levels are associated with a lower risk of stroke and heart attacks.

3. Healthy muscle function 

Electrolytes maintain electrical gradients both inside and outside of muscle cells, which is essential for proper muscle contraction and relaxation.

Lack of potassium or magnesium can lead to poor muscle function, which explains why muscle cramps and Charley horses are among the most common symptoms of electrolyte imbalances.   

4. Stress relief 

Potassium helps calm the nervous system and has muscle-relaxing properties, which can counteract stress-related muscle tension and restlessness. 

5. Balanced pH levels 

Electrolytes help regulate the balance between acids and bases, which is critical to maintaining the pH balance of different bodily fluids.

Proper pH levels are vital for normal cellular function, facilitate enzymatic reactions, and support effective digestive processes.

When should you drink electrolytes?

Many people only consider electrolyte-containing beverages after intense exercise. 

However, electrolytes are not only lost through excessive sweating but can also be depleted by a high-carb diet, coffee and alcohol consumption, dehydration, certain medications, and gastrointestinal issues such as vomiting and diarrhea.  

Incorporating electrolytes into a balanced diet is an excellent strategy to support optimal electrolyte levels associated with improved cardiovascular health, increased energy production, and healthy muscle function.

While most individuals benefit from taking electrolytes, they’re particularly important for people with diabetes, high blood pressure, malabsorption, and other gastrointestinal conditions, as they tend to lose electrolytes at an increased rate.  

It’s best to consume electrolytes daily to counteract the body’s natural loss of electrolytes and consider using electrolytes both before and after exercise. 

Taking pre-workout electrolytes helps prevent dehydration, and post-workout electrolytes can restore the body’s electrolyte balance and speed up recovery.

Signs of electrolyte imbalance

Electrolytes play a critical role in regulating various bodily functions, including energy production, muscle concentration, and nerve signal transmission. 

Imbalanced or depleted electrolytes can impair normal cellular functions and result in a wide range of health issues. 

Here are common signs of electrolyte imbalance:

  • Muscle cramps

  • Fatigue

  • Irregular heartbeat

  • High blood pressure

  • Headaches

  • Dehydration

  • Confusion and brain fog

  • Nausea

  • Digestive issues  

  • Dizziness

Mild electrolyte imbalances can easily be managed at home by consuming electrolyte-enriched water. 

However, severe electrolyte depletion has the potential to be life-threatening and is commonly linked to kidney issues, liver disease, gastrointestinal disorders, or high-intensity exercise, particularly in hot or humid environments.

If you show signs of acute electrolyte depletion, such as extreme thirst, paralysis, muscle weakness, or dry mucous membranes, it’s crucial to seek medical care immediately.
