A form of magnesium

Magnesium gluconate supplements

254 magnesium products in the NIH label database list magnesium as magnesium gluconate (2% of the 15,088 magnesium products); their median is 100 mg of magnesium per serving, against 86 mg across all magnesium products; the 20 whose only supplement ingredient is magnesium list a median of 105 mg (DSLD version 9.4.0, January 2026).

How does magnesium gluconate compare with the other forms?

The median amount of magnesium per serving in products naming each form; the count in brackets. The amount is the magnesium 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 magnesium or the whole magnesium gluconate?

A Supplement Facts row normally states the magnesium itself (a row like "Magnesium (as magnesium gluconate)"); a row named as the compound (a row like "Magnesium gluconate") usually states the compound's weight, which includes what the magnesium is bound to and is larger than the magnesium it supplies. The front of a bottle may print either. Of the 254 products here, 249 give the magnesium in its own row (24 of them an amount far outside what other labels list, or one their own %DV disagrees with); 5 give no amount of their own or one in another unit.

The adult Tolerable Upper Intake Level for magnesium is 350 mg a day; it covers magnesium from supplements and medicines only, not food or water. At the most servings their labels direct, 52 of the 225 magnesium gluconate products with a plausible amount (23.1%) give more than that.
