A form of potassium

Potassium bicarbonate supplements

469 potassium products in the NIH label database list potassium as potassium bicarbonate (4% of the 12,166 potassium products); their median is 170 mg of potassium per serving, against 99 mg across all potassium products (DSLD version 9.4.0, January 2026).

How does potassium bicarbonate 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 bicarbonate?

A Supplement Facts row normally states the potassium itself (a row like "Potassium (as potassium bicarbonate)"); a row named as the compound (a row like "Potassium bicarbonate") 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 469 products here, 467 give the potassium in its own row (5 of them an amount far outside what other labels list, or one their own %DV disagrees with); 1 gives only a row named as the compound, left out of the medians and counts on this site; 1 give no amount of their own or one in another unit.
