Dietary potassium: Why don't you get some of your potassium (K) from your diet. Here is a link that shows you the K content of common foods: http://www.mayoclinic.org/drugs-supplements/potassium-supplement-oral-route-parenteral-route/description/drg-20070753 Common K sources are citrus fruits and potatoes. Who recommended that you have to ingest 4.7 grams of potassium per day and why was that amount recommended?

Dr. Rubin, 4700 mg of potassium is the official Adequate Intake level according to the Food and Nutrition Board of the Institute of Medicine. However, many other authorities question whether it really should be so high.I imagine relatively few people actually ingest that much potassium on an average day. See http://discourse.soylent.me/t/why-is-the-rda-of-potassium-so-high/13064/13 for discussion.

Can do via diet but: While 4700 mg/day is recommended, the average man gets 3200 & woman 2400 in the US, so some believe 4700 is over-ambitious. Supps only have 99mg because higher doses irritate stomachs. Beans, greens, potatoes, tomatoes, avocado & fruit are among the best sources. See http://tinyurl.com/k3jfd5r & http://tinyurl.com/yp35vj for more on sources & and http://tinyurl.com/l6fcw3d for a debate on the RDI.
