It isn't clear that any of those products have an actual Drug Facts label.(an example label [1]) The CVS product listed in the article definitely does not[2]. If it doesn't have a label like this, it is likely not regulated by the FDA and therefor quite a bit more likely to be nonsense. Having ingredient lists not on the Drug Facts label doesn't count.
