ascorbic acid depletes real vitamin c from the body?!

[FishermansWife]

Here we go again! A friend I introduced to vitamin c is in a Facebook magnesium group where these people claim ascorbic acid depletes the bodies real vitamin c and is a pro oxidant. Here's their site. This is so frustrating to have to constantly defend ascorbic acid because of these people.

What do you think of this?

Hi Katie,

You may care to consider:

If it is true, i.e. that

...ascorbic acid depletes the bodies real vitamin c and is a pro oxidant.

I [for one] should be sick or dead [after personally ingesting over 900 pounds of it over the past 20 years] vs. experiencing the seemingly superior health that I am. True? Also, what of the seemingly "miraculous" results achieved by Dr. Cathcart [with many thousands of patients] using [typically] ascorbic acid alone? Those are real-world practical [vs. idealistic theoretical] results!

Those people have a sort of "religious" faith in their "purist" dietary beliefs that flies in the face of tens-of-thousands of studies using ascorbic acid [alone] with beneficial results. Perhaps that "faith" cannot ultimately be argued with using science and/or "real-world" examples.

Here is an excellent article written by Owen dealing with [many of] their assertions: http://vitamincfoundation.org/NaturalC.htm

Also, these two forum topics deal with the subject: http://www.vitamincfoundation.org/forum ... .php?t=758 and http://www.vitamincfoundation.org/forum ... =14&t=1761

I hope that helps, Katie,

David

Why don't you ask them what is the structure of "the real vitamin C molecule", that Kathleen Barnes refers to often?

Nevertheless, Dr. Driskol of the Univ of Kansas, who did the definitive work on the mechanisms of action of ascorbic acid, even referred to it incorrectly as vitamin C. Even when she determined it was a pro-oxidant, not an anti oxidant (which is what the C molecule is.)

This guy is confusing IV with oral C.

Does oral vitamin C (ascorbate) provide the same results?
No. Oral vitamin C is an antioxidant with controlled absorption. Intravenous vitamin C is a pro-oxidant drug that helps produce hydrogen peroxide, which targets neoplastic cells while leaving normal cells unharmed. Because this form is delivered intravenously, plasma and tissue levels are many times above that of oral dosing. - See more at: http://www.kumed.com/medical-services/i ... gENi0.dpuf

If large amounts of vitamin C are presented to cancer cells, large amounts will be absorbed. In these unusually large concentrations, the antioxidant vitamin C will start behaving as a pro-oxidant as it interacts with intracellular copper and iron. This chemical interaction produces small amounts of hydrogen peroxide.

Because cancer cells are relatively low in an intracellular anti-oxidant enzyme called catalase, the high dose vitamin C induction of peroxide will continue to build up until it eventually lyses the cancer cell from the inside out! This effectively makes high dose IVC a non-toxic chemotherapeutic agent that can be given in conjunction with conventional cancer treatments. Based on the work of several vitamin C pioneers before him, Dr. Riordan was able to prove that vitamin C was selectively toxic to cancer cells if given intravenously. This research was recently reproduced and published by Dr. Mark Levine at the National Institutes of Health.

Sodium ascorbate's pro-oxidant effects are not a problem for normal cells because of the presence of sufficient catalase.

fisherman's wife. Keep up the good fight! I haven't gotten through everything but you are correct - and he is wrong. You have Linus Pauling on your side, which has always been a good thing.

Why not send him this (year-old article I was just steered to) http://www.medicine-outsidethebox.com/medicineoutsidethebox-8.htm

Thank you for the information and link! I love a good debate but with ascorbic acid now a big part of my life it seems as though every time I turn around I have to defend it!
