What is potassium chloride




Potassium chloride is made up of potassium and chlorine . It is a white or colorless crystal and is a type of drug known as an electrolyte . These electrolytes help maintain the correct balance of water levels throughout the body.

Potassium chloride is considered as a source of chlorine and potassium. 52% of its weight is potassium and the remaining 48% chlorine. In addition, it is also a flavor enhancer, stabilizer (referred to as E-508) and thickener that is often found in whey protein powders and dairy products.

What is potassium chloride for?

Among its benefits and uses we can highlight:

  • Potassium chloride serves to replace potassium lost in the body . It can be used as a source of potassium or chlorine in deficiency situations caused by inadequate diets, extreme diarrhea or treatment with diuretics.
  • Potassium chloride is sometimes used as a substitute for sodium chloride (salt) . Excessive intake of table salt can cause significant health problems, which is why commercial alternatives such as sodium-free salt, that is, which corresponds to potassium chloride products, are becoming more and more popular. Low sodium content salts that mix sodium and potassium chloride are also used.
  • Other major uses of potassium chloride are to treat or prevent hypokalemia . Potassium levels in the body are affected after suffering from diarrhoea, vomiting or taking drugs, so potassium chloride serves to balance them. Even so, it should always be taken under medical prescription and with the appropriate indications of the specialist for each case. Here you can find out what are the symptoms of a lack of potassium .

How is potassium chloride used?




After discovering all the applications of potassium chloride, it is essential to clarify the recommended dose and the precautions to follow to take it safely.

Recommended Potassium Chloride Dosage

There is no maximum amount of potassium chloride indicated by health agencies, so good manufacturing and use practices are conditioned. That is, it must be used in the minimum amount required to obtain the desired effect of its intake without causing possible side effects.

Potassium deficits in the body are rare, which is why there is no recommended daily intake. However, between 1,600 and 2,000 mg of potassium is considered to be the most adequate intake. The established relationship between potassium and sodium should always be five to one.

Precautions and contraindications

Here are some relevant points to keep in mind before taking potassium chloride :

  • A consumption of potassium chloride in healthy people and in normal amounts (from 4 to 9 grams per day in the total diet) is considered safe. The amounts used as an additive are usually well tolerated, that is, they do not cause digestive or intestinal problems.
  • Consuming higher doses can occasionally cause reactions in people with health problems. Ulcers produced in the small intestine by consuming potassium chloride tablets have also been detected. People who suffer from potassium or sodium metabolism disorders, kidney disease or severe dehydration should avoid consuming this product.
  • The consumption of potassium for chloride simultaneously with digitalis glycosides is also not recommended. Simultaneous use with quinidine helps enhance the antiarrhythmic effects of potassium chloride.
  • If you substitute table salt for potassium chloride, do not forget that any product or ingredient consumed in excess is harmful to the body. Therefore, the use of potassium chloride can be very harmful if consumed in large quantities, causing an excess of potassium.

Potassium Chloride Side Effects




As with other medicines, potassium chloride has side effects that are generally less than the benefit that its consumption brings to health and when they appear it is usually due to misuse or excessive use of the product . These are its main side effects:

  • Nervous system problems: loss of reflexes, mental confusion, tingling or prickling in the feet and hands, weakness and lack of energy.
  • Heart and blood circulation problems: dizziness due to low blood pressure.
  • Immune system problems (fevers).
  • Infusion site problems: redness, swelling, irritation and pain at the injection site.
