Edit links verify (what is ?) Controversy regarding role as Infobox references vitamin [edit]

The scientific journal Nature published the 2003 paper by Kasahara and Kato that essentially stated that PQQ was a new vitamin and in 2005, an article by Anthony and Fenton that stated that the 2003 Kasahara and Kato paper drew incorrect and unsubstantiated conclusions.[9] An article in The Proceedings of the National Academy of Sciences in 2018 identified pyrroloquinoline quinone as a “longevity vitamin” not essential for immediate survival, but necessary for long-term health.[10]
