Many of the electrolytes in the body are very important to the human body. For example, people can speak, can eat, can blink their eyes, can lift their arms, all the movement is actually related to the important physiological functions in the body, is that these electrolyte ions can conduct electrical activity through the continuous flow in the intracellular and extracellular, the formation of action potentials. Nerve conduction is also a form of electrical activity, all through the potential difference that results from the constant flow of some ions to and from the cell, so if there are large fluctuations in electrolytes, physiological functions will be affected. The organism also has a very well developed system to precisely regulate these electrolytes so that they stabilize in a very safe range without major fluctuations. For example, if you drink more water, the concentration of electrolytes in the urine will be low; if you drink less water, the urine will be darker, and the concentration of electrolytes excreted may be higher; all these adjustments are made in order to make the concentration of electrolytes in the blood very stable. Potassium is very important, and when it is low, there is some weakness, bloating, and some very serious cardiovascular problems. High potassium is also very serious and can lead to sudden death; executions in the United States are carried out by potassium injection, so potassium should never be pumped directly from a vein, except through a deep vein. Potassium is a very discreet supplemental substance, and potassium chloride extended-release tablets were created because of this characteristic of potassium. Secondly, potassium can also cause gastric irritation if swallowed directly, so potassium chloride extended-release tablets allow the slow release of potassium through a technological means that allows the tablets to release potassium slowly, while at the same time guaranteeing that the body is able to absorb the potassium so that the potassium deficiency can be corrected.
