Though diet alone usually will not resolve hypokalemia, it’s still beneficial to increase your intake of potassium-rich foods, like fruits, vegetables, beans, and nuts.
In 2019, the National Academies of Sciences, Engineering, and Medicine (NASEM) updated the reference daily intakes (RDI) for potassium, concluding that insufficient data supports the previous recommendation of 4,700 mg of potassium per day for adults.
As such, they developed adequate intakes (AI) based on age and sex. Currently, the AI for potassium is 2,600 mg and 3,400 mg per day for women and men, respectively.
Regardless, because only 85–90% of potassium is absorbed from food, the percent of the Daily Value (DV) listed on food labels remains at 4,700 mg. Keep this in mind to help you ensure you’re getting enough.
