Potassium chloride is a naturally occurring mineral salt that is often used as a substitute for table salt (sodium chloride) in processed foods, and as a supplement to increase potassium intake. Potassium is an important mineral that plays a vital role in many physiological processes in the body, including the regulation of fluid balance, nerve and muscle function, and heart health.
In addition to being used as a salt substitute and dietary supplement, potassium chloride is also used in some protein powders and other nutritional supplements. It is sometimes included in these products as a source of potassium, which can help support healthy muscle function and reduce the risk of high blood pressure.
In terms of safety, potassium chloride is generally considered safe when used in appropriate amounts. However, consuming excessive amounts of potassium can cause hyperkalemia, a condition in which there is too much potassium in the bloodstream. Symptoms of hyperkalemia can include muscle weakness, heart palpitations, and even cardiac arrest. Therefore, it is important to use potassium supplements and potassium-rich foods in moderation.
