Acetyl L-Carnitine supplements

Half of the 933 acetyl L-carnitine supplements in the NIH label database that print an amount list 500 mg or less per serving; the middle half list 200 mg to 525 mg (DSLD version 9.4.0, January 2026). The 173 products whose only supplement ingredient is acetyl L-carnitine list a median of 500 mg.

How much acetyl L-carnitine do supplements contain?

The median product lists 500 mg per serving. One in ten lists 50 mg or less, one in ten 1,000 mg or more. The amount printed most often is 500 mg (292 products).

Which products list the most acetyl 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).
