Potassium is the principal intracellular cation in most body tissues. The concentration of potassium ions is essential to conduct nerve impulses in specialized tissues like brain, heart and skeletal muscle, as well as to maintain normal renal function, acid-base balance, and cellular metabolic functions. The use of compounds containing bicarbonate is showed to produce the release of CO2. This effect has been one of the problems of the use of potassium bicarbonate as it can cause eructation.

The antacid potential of potassium bicarbonate is attained by increasing the gastrointestinal pH by neutralizing hydrochloric acid. The increase in pH results in suppression of the action of pepsin which is the enzyme that exacerbates ulceration due to the presence of acid.

Potassium bicarbonate intake is done mainly in the small intestine in which approximately 90% of the potassium will be absorbed by passive diffusion.

Approximately 90% of the exogenous potassium consumed is lost in the urine while the other 10% is excreted in feces and a very small amount can be found in the sweat. The excreted potassium is freely filtered by the glomerulus of the kidney.
