In addition, mineral co-factors must be available in proper amounts. If any of these parts are missing, there is no vitamin C, no vitamin activity. When some of them are present, the body will draw on its own stores to make up the differences, so that the whole vitamin may be present. Only then will vitamin activity take place, provided that all other conditions and co-factors are present. Ascorbic acid is described merely as the “antioxidant wrapper” portion of vitamin C; ascorbic acid protects the functional parts of the vitamin from rapid oxidation or breakdown.
(Somer p 58 “Vitamin C: A Lesson in Keeping An Open Mind” The Nutrition Report) 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(1 800 526 0189). 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.
