Vitamin C, Linus Pauling was right all along
Taking note of this inconsistency, Drs Steve Hickey and Hilary Roberts decided to investigate the data for a book ("Ascorbate, the science of vitamin C", www.lulu.com/ascorbate). They began by looking at the apparently ludicrous claims for the medical effects of vitamin C. Pauling had stated that the substance could cure cancer and that shortage was the major cause of heart disease. Among his many scientific advances, Pauling had made occasional errors: perhaps he had done the same with vitamin C. If he was wrong, his hypotheses should be easy to refute. When they examined the evidence, Hickey and Roberts found background evidence for Pauling's ideas from independent scientific and medical reports, covering half a century. The findings in these papers could neither be dismissed as placebo effects nor easily explained. The reports included remission of AIDS, cures for cancer, and the immediate recovery of children at the point of death from septic shock. The claims seemed so out of the ordinary that they were hard to believe. However, Hickey and Roberts could find no counter examples in the scientific or medical literature. If these positive reports were indeed wrong, no-one had shown this to be true. The scientific evidence was consistent with Pauling's ideas, with a few notable exceptions. The primary exception was the NIH data on blood and tissue saturation. The medical establishment accepted the NIH conclusions and held them in the highest regard. The US Institute of Medicine had based their official recommended dietary allowance (RDA) on these results. If the NIH was correct, then Pauling was wrong and the positive reports of high doses must be invalid. The NIH conclusions were not correct, however. Hickey and Roberts examined their experiments and found them to be full of errors. For example, the researchers had given a dose of vitamin C, waited until it had been excreted and then measured blood levels. Using this procedure, they found that increasing the dose did not greatly increase the blood levels. Instead of realising that this was because the dose had been excreted, the NIH claimed it was because the body was saturated, so higher doses were redundant. They then used white blood cells as a model for normal cells, to see how they absorbed vitamin C from their surroundings. These white blood cells are specialised to absorb vitamin C, even when supplies are low. If other body cells were similar to white blood cells, we would normally have a reserve of 40 grams in our bodies. In this case, given the proposed RDA of 200mg, it would take 2-3 years to fill a depleted body. This is demonstrably incorrect: the classic example is that James Lind's sailors recovered from scurvy in a matter of days when they were given citrus fruits containing small amounts of vitamin C. These mistakes were gross and unsupportable. In order to check their re-interpretation of the data, Hickey sent emails to the NIH, the Institute of Medicine and every scientist he could contact who was associated with the RDA, asking them to provide a reasonable scientific response to these errors. No-one was able to provide such a response. Since it is normal scientific practice to explain and defend your ideas, the hypothesis that people only need small amounts of vitamin C looks increasingly shaky. Even the NIH's subsequent data contradicts their earlier work. The NIH vitamin C group published a series of papers on vitamin C and cancer [Ann Intern Med, 140(7), 533-7.]. In these papers, they suggested that repeated doses of oral vitamin C would produce blood levels of at least 220 microM (a measure of the concentration) , which is three times greater than the 70 microM maximum "saturated" value they claimed in their RDA papers. While their own papers clearly showed that their low-dose claims were wrong, the NIH appeared not to notice. Instead, they suggested that intravenous doses could produce higher blood levels, which might be effective against cancer. Even though their data were coming closer to Pauling's findings on the use of vitamin C in cancer, the NIH took the opportunity to mount another attack on Linus Pauling, suggesting he did not know the difference between oral and intravenous (IV) vitamin C.

This information is not fake. I'd like you to substantiate that claim, please.
If you have the thinking that only something which gets FDA approved is real, you're just being a bit ignorant.
FDA is bought out by pharmaceutical lobbyists.
Why would anyone pay for tamiflu, when you could just drink green tea, or better yet, get the fruit extract from which the drug is synthesized?

• Natural vs. synthetic ascorbic acid: Natural and synthetic ascorbic acid are chemically identical. As assessed by at least two studies, there appears to be no clinically significant difference in the bioavailability and bioactivity of natural ascorbic acid and synthetic ascorbic acid.
In the November 23, 2000, issue of Nature, one of the premier scientific journals in the world, Dr. Gautam Desiraju of the University of Hyderabad in India contributed a millennium essay about Pauling entitled “The all-chemist”. Desiraju praised Pauling’s astounding revolution of the science of chemistry by noting that the “extrapolation from physics to chemistry and the articulation of chemistry as an independent subject was the handiwork of a single individual. Linus Pauling ranks with Galileo, Da Vinci, Shakespeare, Newton, Bach, Faraday, Freud, and Einstein as one of the great thinkers and visionaries of the millennium.” Desiraju continued, “Chemistry, then, is utterly different from physics and biology in its dependence, at a primal level, on just one scientist.” Citing Pauling’s work on the nature of the chemical bond, the hybridization of bond orbitals (a fundamental concept of organic chemistry), electronegativity, metallic and hydrogen bonds, the structure of benzene, molecular structure, and other concepts that form the basis for modern chemistry, Desiraju proclaimed that Linus Pauling was “not of this age, but for all time.”
• Vitamin C with bioflavonoids: Bioflavonoids are a class of water-soluble plant pigments. Vitamin C-rich fruits and vegetables, especially citrus fruits, are often rich sources of bioflavonoids as well. The effect of bioflavonoids on the bioavailability of ascorbic acid has been examined in two small published studies. In one study synthetic ascorbic acid given in a natural citrus extract containing bioflavonoids (in the ratio of bioflavonoids to ascorbic acid of 4:1), proteins, and carbohydrates, was more slowly absorbed and 35% more bioavailable than synthetic ascorbic acid alone, based on plasma levels of ascorbate over time and 24-hour urinary excretion of ascorbate. In the other study, there was no difference in the bio-availability of 500 mg of synthetic ascorbic acid and that of a commercially available vitamin C preparation with added bioflavonoids, where the ratio of bioflavonoids to ascorbic acid was 0.05:1.

If you get a serious illness like the flu or cancer you want a dose just before bowel tolerance to have the anti-inflammation effects which keep you alive!!
You can get buffered ascorbic acid as ascorbate. Don't take the calcium ascorbate, as it's known to cause problems with that much free calcium floating around.
I just ordered a 3lb bag of sodium ascorbate. If I get the flu, I'm starting with 10 grams hourly until bowel tolerance is reached. Then I stop, take the same dose spread out through the next day. See if I'm okay. Adjust accordingly.

Finally, someone who is well informed about vitamin-c
As far as I can tell, everything you wrote is entirely accurate. Thank you for this contribution.

I initially hurried this thread when the swine flu became all the hysteria, but now wish I would have taken more time. Your thoughts were well written out.
Thanks again..
