"Some of the products included in the recall may contain a higher concentration of active ingredient than is specified; others may contain inactive ingredients that may not meet internal testing requirements; and others may contain tiny particles."
I don't care too much about that part about the inactive ingredients, but "higher concentration of active ingredient" means over-dosage, that's not good to the livers.
Hope what the article says about "the potential for serious medical events is remote" is accurate.
