A form of potassium

Potassium gluconate supplements

283 potassium products in the NIH label database list potassium as potassium gluconate (2% of the 12,166 potassium products); their median is 55 mg of potassium per serving, against 99 mg across all potassium products; the 58 whose only supplement ingredient is potassium list a median of 99 mg (DSLD version 9.4.0, January 2026).

How does potassium gluconate compare with the other forms?

The median amount of potassium per serving in products naming each form; the count in brackets. The amount is the potassium the label gives, as printed (the Supplement Facts row normally states the element; a row named as the compound usually gives the compound's weight and is left out of these figures).

Is the amount the potassium or the whole potassium gluconate?

A Supplement Facts row normally states the potassium itself (a row like "Potassium (as potassium gluconate)"); a row named as the compound (a row like "Potassium gluconate") usually states the compound's weight, which includes what the potassium is bound to and is larger than the potassium it supplies. The front of a bottle may print either. Of the 283 products here, 283 give the potassium in its own row (34 of them an amount far outside what other labels list, or one their own %DV disagrees with).
