                                According to the National Institutes of Health, most multivitamins that include potassium typically contain about 80 mg per serving, while stand-alone potassium supplements are capped at 99 mg. This relatively low dosage, especially compared to the body's daily needs, is due to specific FDA regulations and the potential health risks associated with excessive intake.
