Can you be more explicit as to quantity, potency,etc? People with various conditions, such as kidney failure or mal-metabolism syndromes, can accumulate potassium. Since this electrolyte is essential for the electrical function of the heart, too much or too little can send a person into a fatal arrhythmia. That is why it is essential for doctors to be aware that their patients are taking potassium as a dietary supplement. ------ Regards Mary Ann
