Potassium


Description

Potassium works alongside sodium in the body to maintain the correct fluid balance in the cells and constitutes about 5% of the total mineral content of the body.
Potassium is absorbed by the small intestines and is excreted mainly through urine and perspiration. The kidneys are able to maintain normal serum levels through their ability to filter, secrete and excrete potassium. Aldosterone, an adrenal hormone, stimulates potassium excretion.
Too much salt in the diet can deplete potassium because as the excess salt is excreted from the body it takes potassium along with it.
Coffee also increases the urinary excretion of potassium and alcohol depletes magnesium and potassium.
An adequate amount of magnesium is required to retain potassium in the cells.
 
Function

How potassium works in the body:
Works with sodium to help normalise the heart beat and nourish the muscular system
Unites with phosphorus to send oxygen to the brain
Works with calcium to regulate neurotransmitter activity

Maintains the correct acidity in body fluids
Assists in the conversion of blood sugars into energy
Assists in muscular nerve action
Aids in maintaining healthy skin
Stimulates the kidneys to eliminate poisons and waste from the body
