<P> The European Food Safety Authority (EFSA) refers to the collective set of information as Dietary Reference Values, with Population Reference Intake (PRI) instead of RDA, and Average Requirement instead of EAR . AI and UL defined the same as in United States . For people ages 15 and older the AI is set at 3,500 mg / day . AIs for pregnancy is 3,500 mg / day, for lactation 4,000 mg / day . For children ages 1--14 years the AIs increase with age from 800 to 2,700 mg / day . These AIs are lower than the U.S. RDAs . The EFSA reviewed the same safety question and decided that there was insufficient data to establish a UL for potassium . </P> <P> For U.S. food and dietary supplement labeling purposes the amount in a serving is expressed as a percent of Daily Value (% DV). For potassium labeling purposes 100% of the Daily Value was 3500 mg, but as of May 2016 it has been revised to 4700 mg . A table of the pre-change adult Daily Values is provided at Reference Daily Intake . Food and supplement companies have until July 2018 to comply with the change . </P> <P> Eating a variety of foods that contain potassium is the best way to get an adequate amount . Foods with high sources of potassium include kiwifruit, orange juice, potatoes, bananas, coconut, avocados, apricots, parsnips and turnips, although many other fruits, vegetables, legumes, and meats contain potassium . </P> <P> Common foods very high in potassium: </P>
