In FitDay for Potassium it doesn't have an RDA, but if you look in the column before that it will tell you how much you've been getting. I was having terrible leg cramps the first month or so when I started this WOE. Instead of Potassium I started taking a Magnesium Supplement per my doctors advice and now I take that as well as Calcium/Magnesium and I haven't had any cramps since.
