What is Potassium Magnesium Citrate?

Potassium and magnesium are both essential minerals, meaning they are needed by, but not made within our bodies. Therefore, we must consume these minerals in our diets. However, it has been estimated that Americans generally consume only half the potassium that is recommended by current guidelines [1] and three-quarters of Americans are also estimated to be deficient in magnesium [2]. A supplement, such as Potassium Magnesium Citrate can address both deficiencies with only one capsule per day.

Potassium is an electrolyte and has a tight-knit relationship with sodium, keeping channels functioning to let certain substances move in and out of your cells. As your kidneys control the amount of potassium released from the body, based on intake, if you have problems with your kidneys, problems with potassium levels can follow. 

You can find potassium supplements in several forms, but often you will see it as potassium citrate or potassium chloride. The form included in our supplement is potassium citrate. Potassium citrate is an alkalizing agent and decreases the acidity of urine. This is why it is often recommended as safe to people that have had, or are currently experiencing, kidney stones [3]. Potassium citrate is unlikely to cause any side effects other than an increase in urine, while potassium chloride can cause confusion, anxiety, uneven heartbeat, thirst, muscle weakness, nausea, or numbness [4].

Magnesium citrate is also one of the many forms in which a magnesium supplement can be found. Magnesium citrate dissolves in water and is highly absorbable by the gut, but is less likely to cause diarrhea than some other forms of magnesium supplement [5].


How does Potassium/Magnesium Citrate Work?

Several meta-analyses report a significant reduction in blood pressure (BP) with potassium supplementation, with a greater reductive effect in hypertensive patients [1]. The World Health Organization/International Society of Hypertension released a statement including “increased potassium intake” as a recommendation for reduced incidence of hypertension [1]. The Harvard School of Public Health reported lower risks of hypertension and heart disease also associated with increased magnesium supplementation [2]. Potassium is more effective in reducing BP when administered in a natural form as a combination of magnesium, potassium, and calcium than when consumed alone [1].

Magnesium is a cofactor in more than 300 enzymatic reactions within the body; and thus, it is essential for many crucial physiological functions, such as heart rhythm, vascular tone, nerve function, and muscle contraction and relaxation [6]. Magnesium influences vascular tone and reactivity through regulation of cell membrane sodium pump activity, which in turn affects sodium-potassium transport across cell membranes [7]. Insufficient potassium and magnesium disrupt this physiological process, which can lead to muscle spasms, weakness or eventual breakdown of muscle tissue [7].
