L-Carnitine supplements

Half of the 1,338 L-carnitine supplements in the NIH label database that print an amount list 500 mg or less per serving; the middle half list 110.5 mg to 1,000 mg (DSLD version 9.4.0, January 2026). The 198 products whose only supplement ingredient is L-carnitine list a median of 500 mg.

How much L-carnitine do supplements contain?

The median product lists 500 mg per serving. One in ten lists 25 mg or less, one in ten 2,000 mg or more. The amount printed most often is 500 mg (260 products).

Which products list the most L-carnitine?

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).
