How Does Low Potassium and Magnesium Lead to Restless Leg Syndrome? ?

Can low potassium and magnesium lead to restless leg syndrome?

Do you experience an irresistible urge to move your legs, especially when you’re trying to relax or sleep? If so, you might be familiar with restless leg syndrome (RLS), a neurological disorder characterized by uncomfortable sensations in the legs and an uncontrollable urge to move them. While the exact cause of RLS is still not fully understood, research suggests that imbalances in certain minerals, particularly potassium and magnesium, may play a significant role in its development and severity.

What is Restless Leg Syndrome?

Restless leg syndrome, also known as Willis-Ekbom disease, affects millions of people worldwide. Individuals with RLS often describe sensations such as crawling, tingling, or itching deep within their legs, accompanied by an overwhelming urge to move them. These sensations typically worsen during periods of rest or inactivity, making it difficult to relax or fall asleep. While RLS can occur at any age, it becomes more prevalent with age and can significantly impact one’s quality of life if left untreated.

The Role of Potassium and Magnesium

Potassium and magnesium are essential minerals that play crucial roles in nerve function, muscle contraction, and overall cellular health. When levels of these minerals become deficient in the body, it can lead to a range of neurological and muscular symptoms, including muscle cramps, twitching, and, potentially, restless leg syndrome.


Potassium is an electrolyte that helps regulate nerve signals and muscle contractions. Low levels of potassium, known as hypokalemia, can disrupt the balance of neurotransmitters in the brain, potentially contributing to the development of RLS symptoms. While the exact mechanism linking potassium deficiency to RLS is not fully understood, studies have shown that restoring potassium levels through dietary changes or supplementation can improve RLS symptoms in some individuals.


Magnesium is another vital mineral involved in muscle and nerve function. It plays a key role in regulating muscle contractions and promoting relaxation. Low magnesium levels, known as hypomagnesemia, have been associated with increased muscle excitability and hyperactivity, which may exacerbate RLS symptoms. Like potassium, replenishing magnesium levels through dietary adjustments or supplements may help alleviate RLS symptoms in certain individuals.

Managing Restless Leg Syndrome Through Nutrition

While RLS is a complex condition with various contributing factors, ensuring adequate intake of potassium and magnesium through diet can be an important component of managing symptoms. Foods rich in potassium include bananas, potatoes, spinach, avocados, and citrus fruits, while magnesium-rich foods include nuts, seeds, leafy green vegetables, and whole grains. Additionally, some individuals may benefit from magnesium and potassium supplements under the guidance of a healthcare professional, particularly if deficiencies are identified through blood tests.


Restless leg syndrome can be a frustrating and disruptive condition, but understanding its potential links to low potassium and magnesium levels offers new avenues for management and relief. While further research is needed to fully elucidate the relationship between these minerals and RLS, addressing deficiencies through dietary modifications and supplementation may provide relief for some individuals.

At the Spine and Performance Institute we offer IV Multi-Vitamin Infusions to treat patients with vitamin deficiencies.  We have noticed that many patients with poor nutrition suffer from common orthopedic complaints.  That is why we believe in the importance of the infusions.
