"For my money," Dr. Robert Cathcart, MD's, discovery http://vitamincfoundation.org/www.orthomed.com/titrate.htm that one's body will INDICATE its antioxidant ascorbate needs via its Bowel Tolerance, is a real "magical" discovery. No guessing or blood tests required! Perfect for self-dosing. From my view, we can NOT ingest too many antioxidant electrons, and in fact, undoubtedly, will never be able to ingest enough of them, i.e. for PERFECT health!
Also, my study and experience are that ascorbic acid [counter-intuitIvely] is ULTIMATELY alkalinizing in the body [just like, for instance, lemon juice is].
