Rating (out of 5): 4

Potassium is an essential mineral and electrolyte that plays a critical role in normal muscle function, including maintaining proper muscle tone. Scientific evidence supports the use of potassium for preventing and treating muscle weakness or hypotonia (lack of muscle tone) primarily in the context of potassium deficiency (hypokalemia). Hypokalemia can result from inadequate dietary intake, excessive losses (e.g., through vomiting, diarrhea, or certain medications), or medical conditions affecting potassium balance. Symptoms of hypokalemia often include muscle weakness, cramps, and, in severe cases, significant muscle hypotonia or even paralysis.

When potassium levels are restored—typically through oral or intravenous supplementation—muscle function and tone usually improve, confirming a direct physiological link. Numerous clinical studies and medical guidelines recommend assessing and correcting potassium levels in patients presenting with muscle weakness or decreased tone. However, there is no strong evidence that potassium supplementation improves muscle tone in healthy individuals with normal potassium levels, and unnecessary supplementation can be harmful.

In summary, the use of potassium to support or treat lack of muscle tone is scientifically validated, but primarily as a treatment for hypokalemia-induced muscle weakness or hypotonia. Its use in this context is endorsed by clinical practice guidelines and supported by robust physiological and clinical research.
