  • It can be found in the form of a granular white powder which is colorless and is also hygroscopic .
  • It has a slightly salty taste that is produced by the presence of potassium ions.
  • It is quite soluble in water and for that reason it is generally administered orally.
  • It is a product that can be assimilated by the human body very easily.
  • It has a molecular weight of 306.39.
  • Its boiling point is located at 230 ° C.
  • It has a density of 1.98 g / cm 3 .
  • Its melting point is 180 ° C.

Potassium citrate formula

The molecular formula of potassium citrate is K3C6H5O7 or C6H5K3O7.

Properties (edit)

Potassium citrate has the important property of exerting and producing an alkalizing effect on the human body and thus has the ability to keep urinary pH levels balanced . It is a mineral considered essential which can also be found in a wide variety of foods that are consumed daily. One of its main properties is the ability to maintain a good balance of electrolytes and acid-base in the body.

What is it for?

Potassium citrate has a large number of uses but it is mainly used in the treatment of kidney stones as this product specifically helps to eliminate positively charged atoms, thus reducing the acidity in the urine . It has the ability to crystallize the salts responsible for creating kidney stones such as calcium oxalate and uric acid that is present in the bladder, it also increases the levels of citrate that are present in the urine and thereby reduces considerable form the formation of stones as well as their recurrence.

Has a significant effect on potassium related to blood pressure and the heart rate which makes it possible to work by reducing the risk that exists before a stroke , potassium intake achieves lower blood pressure in people with hypertension and it is also beneficial for the bones.

It also intervenes in maintaining an adequate functioning of the nervous system and the muscular system because when adequate levels of potassium are maintained, sports performance and muscle contractions are improved , for that reason it is considered that potassium citrate helps to develop the entire muscular system and improve its function.

In the field of the food industry , potassium citrate can also be used as a type of preservative, mainly in canned products , frozen fish, soft drinks and sauces, among others. It can also be used as a stabilizing additive , as a chelating agent , in the fortification of some types of isotonic food and drink products and in the production of other types of food as an additive in the case of jellies and jams.

Potassium citrate presentation

Potassium citrate can be found in prolonged-release tablets which should not be chewed. It can also be found in the form of effervescent tablets , in liquid , in the form of granules or in powder .


The recommended doses for taking potassium citrate should generally be indicated by a medical professional . Usually, the doses are divided between 2 or 4 times a day and should be taken immediately after the meal, always following the instructions on the medicine labels. Regarding the maintenance dose , it should be adjusted according to the biochemical results obtained because when potassium citrate is ingested, it is necessary to maintain adequate control of urinary pH .

Side effects

It is important to mention that people allergic to the drug or any of its components should not ingest potassium citrate. People with health problems related to dehydration , high blood sugar or high potassium levels , stomach ulcers , adrenal gland or urinary tract problems should not take the medicine unless directed by a doctor. .

Despite the fact that the side effects are quite rare, some people could develop several of them and even some serious ones . One of the main side effects is an allergy that can appear in the form of hives, red or swollen skin, the presence of blisters , a feeling of tightness in the chest or throat, breathing problems or inflammation in the mouth and face .

In some cases, high levels of potassium in the body can also cause an unstable heartbeat , can cause the person to feel confused and have a feeling of weakness and dizziness . They may experience shortness of breath , extreme tiredness , and weakness . In severe cases, it can cause stool of dark colored or blood and vomit similar to coffee beans .
