Is there a reason that potassium chloride is not a good source of potassium to use for electrolyte replenishment (Gatorade has monopotassium phosphate for example and Liquid IV has dipotassium phosphate).
The Wikipedia page says "In medicine, monopotassium phosphate is used for phosphate substitution in hypophosphatemia." (https://en.wikipedia.org/wiki/Monopotassium_phosphate#Applications)
