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.

Products by amount of potassium per serving
11,751 products, log scale; extreme 0.2% at each end left out of the drawing.
Source: Supplement Facts rows of every product's current label, NIH ODS Dietary Supplement Label Database version 9.4.0; amounts in one measure (weight).
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.
Sources: 21 CFR 101.9(c)(8)(iv) (Daily Values); Institute of Medicine, DRI summary tables (2011) (upper limits); on reading them, the FDA's Daily Value page.
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.

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).
