Over 90% of ascorbic acid in this country is manufactured at a facility in Nutley, New Jersey, owned by Hoffman-LaRoche, one of the world’s biggest
drug manufacturers. Here ascorbic acid is made from a process involving cornstarch and volatile acids. Most U.S. vitamin companies
then buy the bulk ascorbic acid from this single facility. After that, marketing takes over. Each company makes its own labels, its own claims, and
its own formulations, each one claiming to have the superior form of vitamin C, even though it all came from the same place, and it’s really not vitamin
C at all.
