Vitamin C supplements
Half of the 18,583 vitamin C supplements in the NIH label database that print an amount list 100 mg or less per serving; the middle half list 60 mg to 270 mg, and 1 in 82 of the 18,422 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 775 products whose only supplement ingredient is vitamin C list a median of 500 mg, and 1 in 15 of them give more than the upper limit.

Products by amount of vitamin C per serving
18,583 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 vitamin C is 90 mg (adults and children 4 and older). The median product gives 111% of it per serving; the 90th percentile 833%.
The adult Tolerable Upper Intake Level is 2,000 mg a day (total intake from food, water and supplements). At the most servings their labels direct, 224 of the 18,422 products with a plausible amount (1.2%) 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 products list the most vitamin C?
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).
