A form of iron
Ferrous fumarate supplements
1,280 iron products in the NIH label database list iron as ferrous fumarate (15% of the 8,696 iron products); their median is 18 mg of iron per serving, against 5 mg across all iron products (DSLD version 9.4.0, January 2026).
How does ferrous fumarate compare with the other forms?
The median amount of iron per serving in products naming each form; the count in brackets. The amount is the iron 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 iron or the whole ferrous fumarate?
A Supplement Facts row normally states the iron itself (a row like "Iron (as ferrous fumarate)"); a row named as the compound (a row like "Ferrous fumarate") usually states the compound's weight, which includes what the iron is bound to and is larger than the iron it supplies. The front of a bottle may print either. Of the 1,280 products here, 1,272 give the iron 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; 7 give no amount of their own or one in another unit.
The adult Tolerable Upper Intake Level for iron is 45 mg a day; it covers total intake from food, water and supplements. At the most servings their labels direct, 54 of the 1,267 ferrous fumarate products with a plausible amount (4.3%) give more than that.
