    About Potassium

    Potassium is an essential mineral and electrolyte that helps maintain fluid balance, muscle contractions, nerve signals and a steady heartbeat. It also supports healthy blood pressure levels already within a normal range by balancing the effects of sodium. Most Americans get less potassium than recommended.

    This collection includes potassium citrate, potassium aspartate, potassium bicarbonate, liquid potassium and potassium with magnesium from practitioner brands such as Pure Encapsulations, Thorne, Allergy Research Group, Progressive Labs and Trace Minerals.

    How to Choose a Potassium Supplement

    • Potassium citrate: A well-absorbed, alkalizing form. Potassium (citrate) by Pure Encapsulations is our top seller.
    • Potassium aspartate: Bound to the amino acid aspartic acid.
    • Potassium with magnesium: The two minerals work together for muscles and heart rhythm. Potassium Magnesium Citrate by Pure Encapsulations is a popular pick. See magnesium.
    • Why only 99 mg: FDA rules limit most potassium supplements to 99 mg per serving. Food is still the main source.

    Food is the best source of potassium: potatoes, beans, bananas, leafy greens and avocados. If you have kidney concerns or take blood pressure medications such as ACE inhibitors or potassium-sparing diuretics, talk with your practitioner before taking potassium. See also electrolytes.

    Frequently Asked Questions

    What does potassium do?

    Potassium supports fluid balance, muscle contractions, nerve signals and a steady heartbeat. It also helps balance the effects of sodium.

    Why do potassium supplements only have 99 mg?

    FDA rules limit most over-the-counter potassium to 99 mg per serving. Most of your potassium should come from food.

    How much potassium do I need?

    Adults need about 2,600 to 3,400 mg per day. Fruits, vegetables and beans are the best sources.

    Who should avoid potassium supplements?

    People with kidney concerns or who take certain blood pressure medications. Check with your practitioner first.
