Potassium Bicarbonate – Side Effects, Uses, Benefits

Potassium bicarbonate (PB), also referred as potassium acid carbonate or potassium hydrogen carbonate, is a colorless, odorless substance. It is among the food additives encoded by the European Union and is identified by the E number E501.

Potassium Bicarbonate vs Sodium Bicarbonate

Sodium bicarbonate, or baking soda, is a supplement which provides dietary bicarbonate, that can increase serum levels of bicarbonate and subsequently buffer acid production in the body. PB is a low-sodium substitute for baking soda.

Uses

It has been used for decades in everyday products (as a leavening agent in baking and as a food ingredient) and medicine as well as a contact fungicide in a variety of crops, like – pome and stone fruit, grapevine, vegetables, berries and soft fruit, and cereals.

PB is also used as a mineral supplement that is used to prevent or treat low amounts of potassium in the blood, a condition called as hypokalemia.

If you develop this condition, you may experience symptoms, like:

  • muscle cramps;
  • poor energy levels;
  • upset stomach;
  • weakness;
  • abnormal heart rhythm – this is the most life-threatening complication of hypokalemia, especially in individuals with underlying heart disease.

Extreme low levels of potassium can cause the muscles to go completely limp, a medical condition that is known as flaccid paralysis. More importantly, the muscles involved in breathing can be affected by hypokalemia, known as hypokalemic paralysis.

This condition always occurs as a result of excessive loss of this essential mineral through the sweat, urine, or stool. Plus, it is always a symptom of another condition, rather than a disease which occurs by itself.

Moreover, some prescription or OTC drugs can cause excess potassium loss in the urine. These medicines include:

  • blood pressure medications, like – thiazide diuretics (e.g. hydrochlorothiazide) and loop diuretics (e.g. furosemide);
  • amphotericin B (an antifungal medication) as well as the cancer drug, cisplatin, can also cause this condition.

Other causes of low potassium levels may include:

  • leukemia;
  • kidney disorders, like – renal tubular acidosis;
  • magnesium deficiency;
  • AIDS;
  • individuals who have had bariatric surgery (weight loss surgery);
  • too much consumption of alcoholic beverages;
  • Cushing’s disease (a condition which is the result of too much cortisol in the body);
  • eating disorders, like – bulimia and anorexia nervosa.

Note – as long as there are no digestive or metabolic problems present, the leading cause of hypokalemia is simply not getting enough potassium-rich foods in the regular diet.

Benefits

Potassium is one of the human body’s electrolytes, that are minerals which transport an electric charge when dissolved in body fluids, like – blood. This mineral is found mainly in the skeletal muscle and bones. In addition, it participates with another mineral – sodium, to contribute to the normal flow of fluids between the cells in the human body.

The body also requires this mineral for the functioning of many complicated proteins (enzymes) and the contraction of muscles (including the heart).

Dosage

To prevent overdose, in the United States, individual potassium tablets can have no more than 99 mg of the nutrient, just 2% of the recommended 4,700 mg per day. However, extended-release potassium tablets (around 600 milligrams) are given mainly to individuals who take drugs which depletes potassium from the body, like – diuretics, but this type of supplements are available only by prescription.

Also, do not take this supplement if you are taking spironolactone (Aldactone), amiloride (Midamor), or triamterene (Dyrenium).
This supplement may be harmful to an unborn baby, therefore, tell your healthcare professional if you are pregnant.
