A form of zinc
Zinc glycinate supplements
1,215 zinc products in the NIH label database list zinc as zinc glycinate (9% of the 13,751 zinc products); their median is 13 mg of zinc per serving, against 11 mg across all zinc products; the 49 whose only supplement ingredient is zinc list a median of 30 mg (DSLD version 9.4.0, January 2026).
How does zinc glycinate 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 glycinate?
A Supplement Facts row normally states the zinc itself (a row like "Zinc (as zinc glycinate)"); a row named as the compound (a row like "Zinc glycinate") 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 1,215 products here, 1,215 give the zinc in its own row (3 of them an amount far outside what other labels list, or one their own %DV disagrees with).
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, 69 of the 1,212 zinc glycinate products with a plausible amount (5.7%) give more than that.
