Alkali Vitamin C

[fung]

Dear doctor,
My sister who has lung cancer, just recently were suggested by her doctor to take Vitamin C alkali base (PH 7,2) about 6000 mg per day while the brochure inserted stated that anybody can take up to 20.000 mg perday.  
While  OTC  vitamin C I know is acid base with ph 5,2 or ester C with neutral ph , with max intake of 2000 mg /day .
Is this alkali vitamin C has another side effect if taking with the dosage suggested?Could you advise me on this?
Thank you for your attention

You have to understand chemistry here.  Vitamin C is an acid -- ascorbic acid.  That's just how nature made it.  Can't change that.  For most people it's not really a problem, but if you take large doses it can be too acidic.  Even in some foods it's too acidic; which is why one shouldn't overdo oranges.  Too much acid can upset the stomach and interfere with it's natural acid/alkaline balance.  So somebody figured out that if you buffer it with calcium and other minerals, it doesn't have that acidic effect, and therefore you can take more of it without discomfort.  It's not that the non-buffered doesn't work, it does, but there's a limit to how much you can take.  Your doc is using extremely high doses.  If you were just taking a small amount, which is all a person actually needs, the acidic version or just what you get from food would be fine, but the theory is that lots of vitamin C helps fix what all the toxins we've added to our environment and food has done to us.  I don't know if it does or not; there are mixed feelings about it.  Why don't you read up on it?  Personally, I always take buffered C as a supplement to protect my stomach, whatever that's worth as useful information.  By the way, Ester C is just a trademarked form of buffered C.  It is the form I take.

Thanks you so much for your response since I really have no idea about this.
what I want to make sure is, since the doc is prescribed that alkali vit C not only for my sister, but doc  also  assured us it 'd be much better for a healthy person either '
do you think the statement saying that  "taking usual acidic vitamin C is useless bcause our body will digest  vitamin C better in alkali" is true?If that so, why all the vitamin C was made acidic ?

There are no doctors on this forum.  There is a dietician on the other nutrition forum for professional answers.  Vitamin C is always acidic -- it is an acid.  To make it alkaline you buffer it with minerals such as calcium.  There's also a synthetic Vitamin C that's fat soluble called ascorbyl palmitate.  But as to what you're doc is doing, he's using it as a medicine, not a supplement, so the normal rules wouldn't apply.  Linus Pauling championed this.  Have no idea if it works or not, but this is medicine, not supplementation.
