Warning Signs You Have a Potassium Deficiency (+ Best Sources of Potassium)

Without adequate potassium in your diet, your body cannot preserve the health of your blood, heart, muscles, nerves, skin or kidneys.

Potassium is one of the essential minerals that helps to regulate heartbeat and nerve signals. It relaxes muscle contractions and converts glucose into fuel that can be stored for later use by our body. It also reduces swelling, and protects the kidneys while controlling their functions, which includes regulating blood pressure.

While most people think of potatoes or bananas as being good sources of potassium (which they are), other good sources include: dark green leafy vegetables, citrus fruits, apricots, tomatoes, sunflower seeds, whole grains, and most vegetables.


What are the Symptoms of a Potassium Deficiency?

There are many symptoms of a potassium deficiency. Youíll notice that many of the symptoms overlap with other health conditions so you should see a doctor if you have any of these symptoms to rule out other health issues.

  • Constipation
  • Dry skin
  • Extreme thirst
  • Fluid retention, especially in the hands or ankles
  • Heart palpitations, irregular heartbeat, or excessively slow or rapid heartbeat
