author avatar Dr. Eric Berg 12/26/2023

Electrolytes are electrically charged minerals needed to maintain nerve signal transmission, muscle contractions, fluid balance, and energy production. 


Stress, high-carb diets, and excessive sweating can deplete electrolytes, and using an electrolyte powder can help quickly restore electrolyte balance. 


Discover the benefits of electrolyte supplements and learn how to choose the best electrolyte powder to achieve your health and fitness goals.

What are electrolytes?


Electrolytes are mineral ions—such as sodium, chloride, potassium, magnesium, and calcium—that carry a small electric charge when dissolved in a fluid. 


Because of their charge, electrolytes can create electrical currents that play a critical role in maintaining various physiological functions in the body.


Here are some key functions of electrolytes:

  • Facilitate energy production and energy storage

  • Conduct nerve signal transmission 

  • Regulate fluid balance and blood pressure

  • Control muscle function 

  • Maintain pH balance of different body parts 

  • Activate enzymes 


Sodium and potassium are also required for cellular nutrient exchange and waste removal. 


A process known as the sodium-potassium pump creates an electrical gradient that activates carrier proteins needed to transport nutrients and waste products into and out of cells.

Symptoms of electrolyte imbalance


Maintaining proper electrolyte balance is crucial for the normal functioning of almost all cells in the human body.


Electrolyte depletion or an imbalanced ratio of electrolyte minerals can result in a wide range of health issues. 


Here are common signs and symptoms of electrolyte imbalance:

  • Fatigue

  • Irregular heartbeat

  • Muscle cramps

  • High blood pressure

  • Nausea

  • Digestive issues  

  • Dizziness

  • Confusion and brain fog


Severe electrolyte depletion can be life-threatening and typically is associated with kidney problems, gastrointestinal disorders, liver disease, or prolonged intense exercise, especially in hot or humid climates. 


If you suddenly develop symptoms of acute electrolyte depletion, such as muscle weakness, paralysis, extreme thirst, dry mucous membranes, or very dark urine, it’s crucial to seek medical care immediately. 

 Natural electrolyte sources

Natural sources of electrolytes


Electrolytes are found in various foods, and consuming a nutritious and varied diet is crucial to obtaining adequate amounts of all essential electrolytes.  


While most people get enough sodium and chloride from table salt, other electrolyte minerals, such as potassium, calcium, and magnesium, are predominantly found in plant foods and dairy products.   


Contrary to common belief, bananas are not the best source of potassium. Beet tops, avocados, lima beans, spinach, and Brussels sprouts are among the top dietary potassium sources.


Some of the best calcium-rich foods include leafy green vegetables, sesame seeds, cheese, tahini, and sardines, especially if consumed with their bones.  


The top magnesium foods include pumpkin seeds, spinach, Swiss chard, almonds, avocados, leafy greens, and chocolate.

When to take an electrolyte powder


Endurance athletes aren’t the only people who benefit from electrolyte supplementation. Anyone can support hydration and replace lost electrolytes with a high-quality electrolyte powder.


A report released by The Linus Pauling Institute reports that potassium, magnesium, and calcium are classified as shortfall nutrients, meaning many people don’t consume enough of these essential nutrients to maintain a healthy electrolyte balance.


Electrolyte imbalances are directly related to low dietary intake and can be exacerbated by factors such as a high-sugar diet, stress, and certain over-the-counter medications, including diuretics and antacids. 


A high-sodium, low-potassium diet can imbalance electrolytes, which can lead to fluid retention. Achieving the proper sodium-to-potassium ratio is crucial for healthy blood pressure


It can be challenging to obtain a balanced electrolyte mix through diet alone, and electrolyte supplements offer a convenient source of these critical nutrients.  


“Electrolytes are often only considered for exercise,” explains Dr. Berg. “However, incorporating electrolyte supplementation into your daily routine can boost energy production, promote brain function, and enhance overall well-being.”  


While most people can benefit from taking electrolytes, they may be particularly beneficial for individuals with high blood pressure, diabetes, and gastrointestinal conditions and those who consume a high-carb diet.

Benefits of electrolyte powder


Many sports drinks can cause weight gain and dehydration, and electrolyte powders are a great alternative to pre-mixed electrolyte products that can contain as much as 25 grams of sugar per serving. 


It’s well-known that electrolytes maintain fluid balance and help prevent dehydration. However, electrolytes have amazing health benefits beyond fluid regulation.


Here are four reasons why you should consider using electrolyte powder.


1. Boosts energy

Without adequate electrolyte concentrations, your cells are less effective at generating energy. 


Electrolytes, particularly sodium and potassium ions, are needed to maintain an electrical charge within cells, which is crucial for producing adenosine triphosphate (ATP).


ATP is the body’s main energy currency. Research published in Function found that potassium stimulates ATP synthase, an enzyme that regulates energy production and enhances cellular energy reserves. 


2. Lower risk of heart disease

If you struggle to maintain healthy blood pressure despite monitoring your sodium intake, you may not be salt-sensitive but have a potassium deficiency


Electrolytes, particularly potassium, counteract the fluid-retaining properties of sodium. This helps prevent high blood pressure, which is a leading cause of vascular damage and stroke. 


In addition, potassium deficiency can disrupt the electrical signals responsible for regulating heartbeats. A lack of magnesium has been associated with stiff and narrow blood vessels and an increased risk of atherosclerosis and heart attacks.


A study published in The American Journal of Lifestyle Medicine confirms the benefits of electrolytes for heart health and concludes that electrolytes play a pivotal role in maintaining cardiovascular function and lowering the risk of heart disease.

3. Stress relief  

Calcium, potassium, and magnesium are critical for contracting and relaxing muscle fibers.


Replenishing electrolytes can help counteract some of the physiological effects of stress, including muscle tension and restlessness.   


Evidence published in Frontiers In Molecular Science found that potassium is crucial for neuronal health and may enhance stress resilience, which promotes a more balanced stress response and enhances overall mental well-being.


4. Supports skeletal health   

Electrolytes regulate and maintain the body's pH balance, which plays an important role in bone health.  


Stress and sugar can alter your pH by disrupting the body’s acid-base balance. When acidity levels rise, the body releases bone minerals to buffer the blood’s pH levels. This can lead to low bone mineral density and brittle bones. 


Adequate electrolyte intake reduces bone mineral release, thereby preventing the loss of bone mass and reducing the risk of osteoporosis later in life.

How to use electrolyte powder


Using electrolyte supplements in powder form is a convenient way to replenish electrolytes.


However, it’s crucial to choose the right electrolyte product for your health needs and avoid electrolyte drinks that contain added sugar, artificial colorings, and preservatives.


Most electrolyte products formulated for endurance athletes contain higher amounts of sodium and often are enriched with essential amino acids, vitamin C, and other key nutrients.

 

Electrolyte recovery is crucial for athletes. However, a high-sodium electrolyte powder isn’t beneficial for individuals with high blood pressure and those who don’t consume enough potassium. 


Potassium is a crucial but often overlooked electrolyte, and the body requires around 4,700 milligrams daily to maintain adequate levels.  


Data published by the National Health and Nutrition Examination Survey reports that many people only consume 1,900 milligrams of potassium daily, leaving a large proportion of the population at risk of deficiency.


It’s recommended to choose an electrolyte powder that contains calcium and magnesium, has a potassium content of at least 1,000 milligrams, and includes no more than 40 milligrams of sodium per serving to achieve the ideal potassium-to-sodium ratio of 4:1


Electrolyte powders are available in various flavors, such as lemon, lime, or fruit punch, and are typically mixed with water. Alternatively, electrolyte powder can also be added to smoothies, coconut water, protein shakes, or yogurt.   


Most electrolyte powders can be pre-mixed, making them a convenient source of electrolytes that you can sip throughout the day to promote steady energy levels and mental clarity.   


Research published in Critical Reviews in Food Science and Nutrition suggests that the daily use of electrolytes is generally well-tolerated and considered safe. 


However, individuals with kidney problems and those who are taking hypertensive drugs should discuss the use of electrolytes with a healthcare provider to minimize the risk of side effects.
