What is the recommended daily intake of potassium in adults?

1. Potassium is the major intracellular cation and is important for neuron and muscle membrane potentials. 2. The daily recommended intake reflects normal dietary needs. 3. This recommendation is 4700 mg per day. 4. 470 mg and 1500 mg are both different figures a reader might guess from memory, but neither matches the specific figure given here. 5. 9400 mg is also incorrect for the same reason: it does not match the specific figure given here. 6. So 4700 mg is correct; the other values are ten-fold too low or too high. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 26 "Fluid, Electrolyte, and Acid-Base Balance", p.1260-1261 §Potassium_
