Potassium citrate is a powerful, easily absorbed compound made up of potassium and citric acid. An electrolyte, potassium citrate helps cells to ferry electrical charges between the muscles and brain, playing a key role in muscle contraction (including the heart!). 
    Supplementing with potassium citrate may ease discomfort from muscle cramps. It is also a powerful akalyzing agent and can work to prevent kidney stones caused by crystal formation in overly acidic urine.
