What is Potassium citrate

Potassium citrate is a chemical compound consisting of potassium, citric acid and water molecules. It is often used as a potassium supplement as well as a food additive and medicine. Here are some key aspects of potassium citrate:

What is Potassium citrate

Chemical Composition: Potassium citrate is a salt formed by a combination of the mineral potassium, essential for various bodily functions, with citric acid, a weak organic acid found in citrus fruits such as lemons and oranges.


  • Potassium supplement: Potassium citrate is most commonly used as a potassium supplement to help maintain proper electrolyte balance in the body. Potassium is important for muscle and nerve function, fluid balance and various biochemical processes.
  • Kidney stones: It is also used as a medicine to prevent and manage some types of kidney stones. Potassium citrate can help alkalinize urine, making it less conducive to the formation of certain types of stones.
  • Food additive: Potassium citrate is used in the food industry as an acidity regulator, antioxidant, and preservative. It can be found in various processed foods and beverages.
  • Buffer: In some medical applications, potassium citrate is used as a buffering agent to control the pH (acidity) of the solution.

Medical Application:

  • Urine alkalization: As previously mentioned, potassium citrate is used to raise the pH of urine, which can help prevent the formation of calcium-based kidney stones. This makes the urine less acidic, which makes it more difficult for certain types of crystals to form.
  • Metabolic acidosis: Potassium citrate may also be prescribed to manage conditions such as metabolic acidosis, where the body accumulates excess acid due to kidney dysfunction or other factors.
  • Gastrointestinal conditions: In some cases, potassium citrate may be used to treat certain gastrointestinal conditions, such as preventing acid-related damage to the lining of the stomach or intestines.

It is important to note that while potassium is essential for health, excessive intake of potassium, whether through supplements or potassium-rich foods, can have adverse effects, especially for individuals with kidney problems or certain medical conditions. Consulting a healthcare professional is recommended before using potassium citrate supplements or medications.
