Fiber supplements

Half of the 6,987 fiber supplements in the NIH label database that print an amount list 2 g or less per serving; the middle half list 1 g to 4 g (DSLD version 9.4.0, January 2026). The 506 products whose only supplement ingredient is fiber list a median of 2 g.

How much fiber do supplements contain?

The median product lists 2 g per serving. One in ten lists 1 g or less, one in ten 6 g or more. The amount printed most often is 1 g (2,773 products).

Which products list the most fiber?

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).
