5 Signs of a Potassium Deficiency

The Western diet is notorious for lacking in many vital vitamins and minerals required to sustain optimal nutrition and quality of health. One of these nutrients deficient in this diet is potassium. Potassium is a critical plant rich nutrient that assists the body in a variety of physiological functions. Among these include its ability to improve bone health, sustain brain health and prevent cognitive decline, maintain cardiovascular health, decrease the risk of kidney stones and many more benefits.

Do you know if you are getting enough potassium into your diet? If are among many others with a lot of stress, a high salt consumption, kitchen full of processed foods, diet containing minimal fruits and vegetables and frequently find yourself eating food outside the home, you may be silently destroying your body.

Do You Need More Potassium?

Aging is one of the most threatening risk factors that affects our body’s ability to perform optimally. Stress, especially as we age, promotes oxidative damage to potassium channels in tissue such as the brain.

Degeneration of these potassium channels causes brain alterations which triggers symptoms of Alzheimer’s disease such as brain fog and memory loss. Seeing as how we are all aging, and stress is inevitable, chances are that you need to increase your intake of potassium. (4)

Adrenal Fatigue:  When we are under stress, we utilize a lot of potassium and other electrolytes in order to produce the electrical currents that run our body.  If we are unable to replace potassium and other electrolytes than it puts even more stress on our adrenals and can lead to adrenal fatigue where we are unable to keep up with the demands of our environment.

Hypertension: One common sign that your body is deficient in potassium is that you experience symptoms of cardiovascular dysfunction. Adequate potassium intake helps to lower blood pressure in individuals with both high and normal blood pressure levels.  Epidemiological studies find that the higher the sodium to potassium ratio, the higher the risk for hypertension, disease, morbidity and death (1, 3).

Muscle Cramping: Are you prone to muscle spasms or cramping? These symptoms may be a sign that you have an imbalance of electrolytes and can be due to a potassium deficiency. Both cellular and circulating concentrations of potassium is required for systemic electrolyte balance (5).

Weak Bones: Potassium acts as a buffering agent for pH balance especially associated with bone density. Acidic salts can lead to a degenerative process known as bone demineralization which pulls nutrients from bones. Demineralization is a major factor in bone fractures, osteoporosis and tooth decay. (2)

Kidney Stones:  When we are deficient in potassium, we excrete more calcium into our urine.  This concentrates calcium into the bladder where it can combine with oxalate compounds to produce kidney stones.

Potassium Rich Foods

The National Academy of Sciences recommends 4,700 mg of potassium daily to reap the rewards of proper potassium homeostasis (7). Other evidence suggests that health benefits can be observed at daily concentrations 1,000 mg less at only 3,700 mg daily (6). Unfortunately, many of us are receiving far less than even close to the recommended daily intake. Many studies suggest that consuming more than 3,000 mg potassium is on the highest average (1).

Listed in ascending order from containing the highest content of potassium to the least amount, supplementing the following foods into your diet is an effective strategy to improve your overall health by boosting potassium intake. (6, 7, 8)

  1. Swiss chard: 1 cup offers 961 mg of potassium and is one of the best sources of this nutrient
  2. Spinach: Contains 839 mg potassium / 1 cup
  3. Avocados: 728 mg potassium/ 1 cup
  4. Almonds: Unsalted and dry roasted almonds have 746 mg potassium in every ½ cup serving
  5. Brazil Nuts: Along with almonds, brazil nuts are among the highest in potassium and lowest in sodium content in the family of nuts; ½ cup of unblanched brazil nuts contains 659 mg
  6. Bok choy: Contains 631 mg / 1 cup and is considered one of the best vegetable sources
  7. Beets: Every cup of beets contains about 519 mg; Eating the beet greens will even get you an additional 654 mg of potassium for every ½ cup of cooked greens
  8. Brussel sprouts: 495 mg potassium / 1 cup
  9. Broccoli: 457 mg potassium / 1 cup
  10. Cantaloupe: 427 mg potassium / 1 cup
  11. Tomatoes: Loaded with 426 mg for every 1 cup of tomatoes; Consuming ¼ cup tomato paste offers 664 mg potassium and 1 serving of tomato juice can have 556 mg
  12. Kiwi: 1 kiwifruit offers 215 mg potassium
  13. Figs: A single medium sized fig has 116 mg potassium
  14. Apricots:– One apricot contains 91 mg potassium

Cardiovascular Health Benefits

Among the strongest evidence for increasing potassium intake is its direct relationship potassium has on improving cardiovascular health. A diet high in potassium has been shown to lower blood pressure, and reduce the risk for cardiovascular disease related death. Conversely, a diet low in potassium consumption is linked to a higher risk of chronic heart failure and even stroke. (1, 3)

Recently researchers have discovered that potassium also plays a critical role in our adrenal health and is also associated with blood pressure. It has been long understood that potassium assists in regulating the sympathetic nervous system which consists of involuntary responses and includes smooth muscle such as blood vessels and even the stomach (5, 6). For this same reason, potassium improves blood flow and prevent damage to blood vessels (4).

Similar to other biological functions, adrenal cells require a voltage produced by potassium ions (K+) to function properly. Depending upon potassium concentrations, the adrenal gland can inhibit or secrete a steroid hormone called aldosterone. Aldosterone causes the body to retain sodium and increase blood pressure in instances of hypotension but consequentially does the same when potassium levels are low. (5)

Improves Renal Health

The adrenal gland is intricately associated with potassium through a compound known as NCC that is activated when cellular levels of sodium and chloride are imbalanced with potassium. Just as a series of pathways become disturbed from a potassium imbalance with the adrenal gland, kidney health is also dependent on potassium levels.

A high potassium diet can slow the progression of renal disease and help manage kidney stones (1, 3, 5). It does this by reducing the excretion of calcium which can form as hard deposits in the kidney during excretion.

Potassium Contributes to Bone Health

Approximately 50% of people are estimated to have osteoporosis over their lifetime (2). Along with common risk factors we often hear of including calcium and vitamin D deficiencies, poor potassium intake is also essential for proper bone health.

Increasing the amount of potassium in your diet is needed to improve the ratio of potassium to sodium. Individuals with a higher concentration of sodium than potassium have a 50% increased risk of developing osteoporosis. Potassium helps remove sodium from the body thus allowing more nutrients to remain within the bone. An increase in potassium is also found to stimulate osteocalcin formation which is evidence of bone formation and nutrient density. (2, 6)

    are potassium supplements safe I know that I am low in potassium and my sodium potassium ratio is off the chart, and although I eat potassium rich foods I just can’t eat enough. I have been told that potassium supplements aren’t safe so I’m confused. What do you think?

    • Dr. Jockers May 19, 2016 at 5:32 am #

      Hey Mary,

      Yes potassium supplementation is safe. I like to focus on consuming lemons/limes, avocados, etc. to take in more potassium as well!

    What kind of supplements can I buy?
