Physiological role of potassium and magnesium

Physiological role of potassium and magnesium

Dr. Denis Slinkin states: Potassium is the main intracellular ion. Normal body function depends on the concentration of potassium inside the cell and in intercellular fluid. 

Adequate supply of potassium with food provides an electrical impulse, which is necessary for heart function and reduction of smooth and transversely striped muscles, the implementation of brain function and the peripheral nervous system; maintenance of intracellular osmotic pressure; water balance.

Potassium acts as an activator of some enzymes; regulates the activity of potential-dependent channels; it is necessary to maintain endothelial function of blood vessels; normal blood pressure level (BP); acid-alkaline balance in the body; influences the release of hormones (insulin).

Magnesium is the eighth most widespread element of the Earth’s crust, a vital mineral, the second most prevalent intracellular electrolyte after potassium and the fourth most cations in the body. 

Dr. Denis Slinkin

Its content in the body of an adult is about 1000 mmol (or 24 g), i.e. 20 mmol/kg of muscle mass. The main magnesium depot is bone tissue, which contains about 50-60% of its total content, and in muscles and other soft tissues – about 40-50%. It is essential for muscle relaxation, regulates the mineralization of bone tissue, its uniform growth, flexibility, strength and increases the reparative potential of bones.

Approximately one third of the magnesium contained in the bones is available to maintain its level outside the cell. Extracellular magnesium in the body (less than 2% of all magnesium) is found in plasma and red blood cells, according to Dr. Denis Slinkin.

Dr. Denis Slinkin states:Magnesium is present in all cells as a cofactor of more than 300 enzymes involved in glucose metabolism, protein and nucleic acid synthesis, energy formation and transfer, regulation of smooth muscle tone in blood vessels and endothelial cell function, as an anti-ion for macroergic compounds (ATP) and nucleic acids, regulates transmembrane transport, plays a role in maintaining protein structure, DNA stabilization, synthesis and metabolism of catecholamines (noradrenaline), acetylcholine and other neurotransmitters, and neuropeptides in brain tissue.
