Riboflavin supplements

Half of the 9,824 riboflavin supplements in the NIH label database that print an amount list 4 mg or less per serving; the middle half list 1.7 mg to 25 mg (DSLD version 9.4.0, January 2026). The 85 products whose only supplement ingredient is riboflavin list a median of 100 mg.

How much riboflavin do supplements contain?

The median product lists 4 mg per serving. One in ten lists 0.6 mg or less, one in ten 50 mg or more. The amount printed most often is 1.7 mg (1,344 products).

How do the amounts compare with the Daily Value and the upper limit?

The FDA Daily Value for riboflavin is 1.3 mg (adults and children 4 and older). The median product gives 308% of it per serving; the 90th percentile 3846%.

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.

Which products list the most riboflavin?

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).
