Potassium supplements

Half of the 11,614 potassium supplements in the NIH label database that print an amount list 99 mg or less per serving; the middle half list 50 mg to 190 mg (DSLD version 9.4.0, January 2026). The 290 products whose only supplement ingredient is potassium list a median of 99 mg.

How much potassium do supplements contain?

The median product lists 99 mg per serving. One in ten lists 20 mg or less, one in ten 330 mg or more. The amount printed most often is 99 mg (630 products).

How do the amounts compare with the Daily Value and the upper limit?

The FDA Daily Value for potassium is 4,700 mg (adults and children 4 and older). The median product gives 2% of it per serving; the 90th percentile 7%.

The upper limit is for total intake from food, water and supplements unless stated, and does not apply under medical supervision. A label amount is what the maker printed. This is data, not advice: the NIH ODS fact sheets explain what each nutrient does.

Which forms of potassium do labels name?

Potassium citrate is the form named most often: 1,756 of the 12,166 potassium products (14%), ahead of potassium chloride (1,494, 12%) and potassium bicarbonate (469, 4%). A product naming two forms counts in both; the table below gives every form.

• Potassium citrate
• Potassium chloride
• Potassium bicarbonate
• Potassium gluconate

Which products list the most potassium?

On-market products, per serving, with a plausible amount: the rule leaves out likely entry slips, such as an amount far beyond every other label with no %DV or strength on the label to back it (each product page still shows its own amount, marked).
