Protein supplements

Half of the 8,985 protein supplements in the NIH label database that print an amount list 16 g or less per serving; the middle half list 2 g to 24 g (DSLD version 9.4.0, January 2026). The 543 products whose only supplement ingredient is protein list a median of 6 g.

How much protein do supplements contain?

The median product lists 16 g per serving. One in ten lists 1 g or less, one in ten 30 g or more. The amount printed most often is 1 g (1,680 products).

Which products list the most protein?

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).
