Inositol supplements

Half of the 4,042 inositol supplements in the NIH label database that print an amount list 30 mg or less per serving; the middle half list 10 mg to 80 mg (DSLD version 9.4.0, January 2026). The 104 products whose only supplement ingredient is inositol list a median of 700 mg.

How much inositol do supplements contain?

The median product lists 30 mg per serving. One in ten lists 1 mg or less, one in ten 235 mg or more. The amount printed most often is 50 mg (622 products).

Which products list the most inositol?

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).
