Zinc supplements
Half of the 13,186 zinc supplements in the NIH label database that print an amount list 11 mg or less per serving; the middle half list 5 mg to 15 mg, and 1 in 17 of the 13,065 with a plausible amount give more than the adult upper limit at the most servings their labels direct (DSLD version 9.4.0, January 2026). The 418 products whose only supplement ingredient is zinc list a median of 30 mg, and 44% of them give more than the upper limit.

How much zinc do supplements contain?
The median product lists 11 mg per serving. One in ten lists 2.2 mg or less, one in ten 30 mg or more. The amount printed most often is 15 mg (2,885 products).
Products by amount of zinc per serving
13,372 products, log scale; extreme 0.2% at each end left out of the drawing.
Source: Supplement Facts rows of every product's current label, NIH ODS Dietary Supplement Label Database version 9.4.0; amounts in one measure (weight).
How do the amounts compare with the Daily Value and the upper limit?
The FDA Daily Value for zinc is 11 mg (adults and children 4 and older). The median product gives 100% of it per serving; the 90th percentile 273%.
The adult Tolerable Upper Intake Level is 40 mg a day (total intake from food, water and supplements). At the most servings their labels direct, 786 of the 13,065 products with a plausible amount (6.0%) give more than that from the supplement alone (what counts as plausible).
The upper limit is for total intake from food, water and supplements unless stated, and does not apply under medical supervision. A label amount is what the maker printed. This is data, not advice: the NIH ODS fact sheets explain what each nutrient does.
Sources: 21 CFR 101.9(c)(8)(iv) (Daily Values); Institute of Medicine, DRI summary tables (2011) (upper limits); on reading them, the FDA's Daily Value page.
Which forms of zinc do labels name?
Zinc oxide is the form named most often: 2,798 of the 13,751 zinc products (20%), ahead of zinc citrate (2,614, 19%) and zinc gluconate (1,509, 11%). A product naming two forms counts in both; the table below gives every form.

Which products list the most zinc?
On-market products, per serving, with a plausible amount: the rule leaves out likely entry slips, such as an amount far beyond every other label with no %DV or strength on the label to back it (each product page still shows its own amount, marked).
