POTASSIUM: The Most Important Electrolyte Yet an Ignored Epidemic - Dr. Berg

author avatar Dr. Eric Berg 10/20/2023

Potassium is an essential electrolyte critical to sustaining good health and well-being. It produces positively charged ions when dissolved in the body's fluids, allowing it to conduct electricity and support various physiological processes.

Let's explore the significance of potassium as an electrolyte, its roles and function, and the numerous health benefits associated with adequate potassium intake.

Furthermore, we'll discuss potential causes and symptoms of potassium deficiency.

Causes and Symptoms of Potassium Deficiency

Potassium deficiency, also known as hypokalemia, can occur due to various factors that affect the body's potassium levels.

Identifying these causes and recognizing the symptoms associated with low potassium intake is essential to ensure proper electrolyte balance in our bodies.

Potassium-rich foods

Lack of potassium-rich foods

An inadequate dietary intake of potassium-rich foods is one of the leading causes of hypokalemia.

A diet low in fresh produce and high in processed items may not offer enough potassium for optimal well-being. To maintain healthy potassium levels, it is crucial to incorporate a wide variety of vegetables into your daily meals.

Digestive issues

Excessive loss of potassium through vomiting or diarrhea can also lead to deficiency.

Gastrointestinal issues such as inflammatory bowel disease (IBD), celiac disease, or Crohn's disease may cause malabsorption problems that impair nutrient absorption, impacting adequate amounts of potassium.

If you suffer from gastrointestinal disorders affecting nutrient absorption, consult a healthcare professional about appropriate dietary changes or supplementation options.

Other factors that may cause potassium deficiency include:

  • Excessive sweating during intense physical activity

  • Use of diuretics or laxatives

  • Kidney disorders affecting potassium excretion

  • Certain medications, such as beta-blockers and corticosteroids, can affect electrolyte balance.

Symptoms of Potassium Deficiency (Hypokalemia)

If you suspect a potassium deficiency, watch out for these common signs:

  1. Fatigue: Low energy levels could indicate an imbalance in electrolytes due to insufficient potassium intake.

  2. Muscle weakness or cramps: Low blood concentrations may lead to muscular problems like twitching or tremors.

  3. Digestive issues: Constipation and bloating are common symptoms of low potassium levels.

  4. Irregular heartbeat or palpitations: Potassium is vital in maintaining normal heart function; thus, deficiencies can result in arrhythmias or irregular heart rhythms.

  5. Numbness or tingling in the extremities may be a sign of hypokalemia, so it is essential to seek medical advice if these symptoms occur.

Consult with a healthcare professional if you experience any of these symptoms, as they can help determine the cause and recommend appropriate treatment options. You can ensure optimal health and well-being by addressing potassium deficiencies early on.


Potassium is essential for optimal health and preventing vascular calcification and sodium toxicity.

Incorporate potassium-rich foods like avocados, green leafy vegetables, mushrooms, and salmon into your diet to promote healthy muscle function and fluid balance and support energy production and mental focus.
