Proprietary Blend supplements

Half of the 9,259 proprietary blend supplements in the NIH label database that print an amount list 500 mg or less per serving; the middle half list 150 mg to 1,156 mg (DSLD version 9.4.0, January 2026). The 174 products whose only supplement ingredient is proprietary blend list a median of 500 mg.

How much proprietary blend do supplements contain?

The median product lists 500 mg per serving. One in ten lists 50 mg or less, one in ten 3,000 mg or more. The amount printed most often is 1,000 mg (425 products).

Which products list the most proprietary blend?

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).
