Hi, im sorry but i really got no time to read all of this.

What is the conclusion for oral AA/SA? how much per day is the most efficient method?

Should i still use 10g per day in split doses or?

Need and tolerance for vitamin C are too individual for giving a efficient method for everyone at everytime. Some tolerate only a few grams, while with a flu that tolerance could go up to 100 grams for some time.

It's always good to split up doses due to the short half-life of vitamin C. Also adding some Sodium bicarbonate to the Ascorbic acid, to let it combine to Sodium ascorbate, helps in spreading the absorption rate and lessening the acidity.

For the dose itself you have to experiment how much AA you tolerate before gastrointestinal complaints begin, and dose accordingly.

This is not what i asked, sorry if i was not clear.

What i ask is how many grams should i consume, and should i at all? since now im reading someone that anything above 500mg at once dose, and 500 next and so on, is useless, like no plasma level change?

I need general info, is the bowel tollerance even effective or we just dump the vit c? cause if the plasma level does not rise its just money down the toilet.

So should i go on with 1 gram per hour dose (or so) or cut it in preventive 2 grams per day?

Does 1 gram per hour > 500 mg per hour?

Dose 2 gram per hour > 1 gram per hour?

This is in regard to absortion/blood/plasma levels/benefits.

I am posting this draft before submitting a paper on these bioavailablity of vitamin C measures.

http://www.vitamincfoundation.org/pdfs/BioAvailDraft10102016.pdf

JOHNWEN - I would like to acknowledge your contribution in making the charts, but I would understand completely if you don't want me to use your name publicly :wink:

So please Yay/Nay including you by real name in acknowledgements. (Otherwise I could say forum user "johnwen")

And if anyone has any comments about the paper, now is the time!

This is preliminary. I plan to expand and be more comprehensive in a future version aimed at more mainstream journals.

The last post contains a spreadsheet graphs of the data collected in this thread.

The first paper will be printed in the next Townsend Letter for Doctors and Patients.

An updated paper with more experiments has been submitted to the Journal of Orthomolecular Medicine.

Thanks to everyone for their help - especially johnwen. We will post a link to the PDF of the paper after it is published in JOM.
