Which products list the most aspartic acid?

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).

Have the amounts changed over the years?

Products whose current label entered DSLD in 2012 list a median of 913 mg; those entered in 2024, 108 mg.
