A form of zinc
Zinc monomethionine supplements
436 zinc products in the NIH label database list zinc as zinc monomethionine (3% of the 13,751 zinc products); their median is 15 mg of zinc per serving, against 11 mg across all zinc products (DSLD version 9.4.0, January 2026).
How does zinc monomethionine compare with the other forms?
The median amount of zinc per serving in products naming each form; the count in brackets. The amount is the zinc 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 zinc or the whole zinc monomethionine?
A Supplement Facts row normally states the zinc itself (a row like "Zinc (as zinc monomethionine)"); a row named as the compound (a row like "Zinc monomethionine") usually states the compound's weight, which includes what the zinc is bound to and is larger than the zinc it supplies. The front of a bottle may print either. Of the 436 products here, 435 give the zinc in its own row (1 of them an amount far outside what other labels list, or one their own %DV disagrees with); 1 give no amount of their own or one in another unit.
The adult Tolerable Upper Intake Level for zinc is 40 mg a day; it covers total intake from food, water and supplements. At the most servings their labels direct, 35 of the 434 zinc monomethionine products with a plausible amount (8.1%) give more than that.
