Re: Vitamin C and S. Boulardi: A Simple Experiment

 True, S. Boulardi is not pathogenic.  The purpose of the test was to clear up some confusion regarding whether Vitamin C is cidal for yeasts. There is conflicting information on the subject.

But this does not clear up anything.  Vitamin C is an acid (ascorbic acid).  But when acids leave the stomach they are neutralized by bicarbonate.  Even if you took enough to overwhelm the bicarboanate buffer system this will just strain the body's buffer system leading to other health issues.  In addition the vitamin C will still come in to contact with other substances in the intestines leading to further neutralization or binding of the ascorbic acid not already being absorbed.  For example synthetic ascorbic acid is extremely unstable and can be broken down in to toxic oxalic acid.  This can either be absorbed leading to the possibility of kidney stones or it bind to minerals in the intestines forming insoluble oxalates.  These are good examples why "test tube" studies do not tell us how something will function in the body.
