* You should aim to eat fruit and vegetables that provide you with 4700 mg or more of potassium each day.
* Don't worry about potassium in your sports drink. It's far more important to get plenty of sodium, but a little potassium won't do any harm.
** If you're competing in a race where your fluid intake is very high, then potassium supplementation may become more important.
* [[Magnesium]] supplementation may be required as part of treating low potassium levels. (Magnesium deficiency is extremely common.)
* Be careful when recovering from a bout of nausea or diarrhea as this can cause life-threatening potassium deficiency.
* If you or someone you know is suffering from an eating disorder, please seek professional help.
