Frequently Asked Questions about Potassium Supplements

How much potassium should you take per day?

The amount of potassium needed may vary depending on age and individual circumstances. For adults, EFSA indicates an adequate intake of 3,500 mg per day, taking into account the total potassium intake from the diet.

This value does not represent a standard dose to be taken through a food supplement. Potassium is mainly obtained through food, and the amount provided by a potential supplement should be assessed by also considering the overall dietary intake.

When should you take a potassium supplement?

There is no specific time of day that is considered best for taking a potassium supplement. It is advisable to follow the directions for use provided by the manufacturer and adhere to the daily dose stated on the label.

The time of intake can be incorporated into your daily routine according to the product directions, without considering a specific time of day as universally valid.

Are all potassium supplements the same?

No, potassium supplements are not all the same and may differ in the chemical form used, the amount of potassium per serving, the format and the presence of other ingredients.

Different formulations may contain, for example, potassium citrate and potassium chloride, which are different potassium salts. Even products using the same form may provide different amounts of the mineral per serving or have different intake instructions.

How do you choose a potassium supplement?

To choose a potassium supplement, it is useful to first assess the form of the mineral and the amount actually provided by the daily dose. It is important to check any added ingredients, the number of servings per package, the format and the intake instructions provided on the label. 

Some formulations contain potassium alone, while others combine this mineral with other nutrients, such as magnesium.
