5 Orthomolecular means "the right molecule." Dr. Linus Pauling

6 Vitamin C: The Electron Exchanger Albert Szent-Gyorgyi, M.D., Ph.D Nobel Prize winner in Medicine Awarded for the discovery of vitamin C, in connection with biological respiration one of the primary substances assuring that a vigorous, continuing electron exchange takes place among the body s tissues and molecules.

7 Dr. Thomas Levy Curing the Incurable One definition of life a state in which an optimal degree of electron interchange among cells can take place.

9 Optimum Dosing of Vitamin C in Humans? Humans lost the ability to make vitamin C due to a genetic mutation GLO coverts glucose into vitamin C L-Gulonolactone Oxidase mutated

26 Toxicity of vitamin C to tumor cells derives from high GLUT1 expression by tumor cells Vitamin C may alter intracellular metabolism in cancer cells by disrupting the redox balance. High-dose vitamin C blocked the energy flux in glycolysis and the Kreb s Cycle ATP production is inhibited Science. 2015, 350: 1391

30 Cameron and Pauling 10 grams of IVC daily for 10 days followed by 10 grams orally in terminal cancer patients 1976 paper in Proc. Natl. Acad. Sci. Unclear if 10 gram oral C dose was single or divided 4-fold increase in life expectancy They speculated that larger amounts than 10 gr/d might have a greater effect. New Discovery! The 10 gram IVC was by 24 hour CONTINUOUS INFUSION

31 Mortel, et al Two randomized, double blind, placebo-controlled studies at Mayo Clinic 10 grams of oral C once daily in 200 late stage cancer patients No statistical benefit (but the study was not an actual replication of Cameron, Pauling s work) The Mayo studies were taken as definitive by the oncologic community

33 Vitamin C Pharmacokinetics: Implications for Oral & IV Use Ann Intern Med. 2004;140: Padayatty, Riordan, Levine, et al to 1.25 gr of ORAL and IV Ascorbate Plasma C level measured after administration After 1.25 gr. ORAL 135 mm/l After 1.25 gr. IV 885 mm/l NOTE Acute Sepsis Rx Dose = 1.5 gr q6hr

34 Dual-Phase Ascorbic Acid Pharmacokinetics Phase 1 low plasma levels of AA < 70 mm/l < 1.2 mg/dl (USA units) renal transporters actively reabsorb AA oxidized ascorbate (DHA) is NOT reabsorbed

35 Dual-Phase Ascorbic Acid Pharmacokinetics Phase 2 high plasma levels of ascorbate >70 mm/l < 220 mm/l mg/dl AA is rapidly excreted similar to small, water-soluble molecules

36 Dual-Phase Ascorbic Acid 220 Pharmacokinetics mm/l Phase 2 AA is rapidly excreted 70 mm/l Phase 1 AA is actively reabsorbed

37 220 Ascorbic Acid Half-life mm/l 70 mm/l Phase 2 AA is rapidly excreted 30 minutes Phase 1 AA is actively reabsorbed 8 40 days if intake is deficient!

38 Reference Range of Ascorbic Acid at the BioCenter Laboratory mm/l 70 mm/l Phase 2 AA is rapidly excreted Phase 1 AA is actively reabsorbed BioCenter Lab 6634 fasting plasma C levels only 50 > 120 mmol/l

39 Dynamic Flow vs. Saturation NIH computer models predict plasma saturation of vitamin C after 200 mg of oral C This ignores the effect of repeat dosing of standard C and newer liposomal C preparations With a Phase 2 half-life of 30 minutes, frequent dosing of C q3-4 hrs will result in plasma levels that can readily exceed the 220 mm/l prediction (as demonstrated in observations noted above)
