I’m glad the conclusion says the products lists are not the only ones to which this letter applies. Otherwise Amazon could just remove the products mentioned and make the FDA play wack-a-mole. As a side note, this letter is exactly why I think a regulatory agency like the FDA is absolutely necessary. This stuff can kill people and it is impossible for the average person to protect themselves.
Saying that, the search returns hundreds of other supplements in the same category, with similar nonsensical names. They are certainly attempting to play wack-a-mole.
