Question

Why can the body handle 4700mg of potassium but the amount in most supplements is 99mg?

Answer 1

because potassium is water soluble, and can be passed through the body as waste.  Whatever it doesn't need, it discards.  

99mg is likely an FDA RDA (recommended daily allowance) for a supplement in the form you are taking.  You wouldn't want to ingest 4700mg of potassium on a regular basis or you'd likely s***w up kidneys and liver.  

Answer 2

i haven't  a clue but do let me know when you find out
