Vitamin C Foundation Ascorbic acid (C6H8O6) is the most common form of vitamin C. "It is an essential food for human beings. People who receive no ascorbic acid become sick and die." - Linus Pauling (Vitamin C and the Common Cold, 1970).

The Vitamin C Lecture that Every Medical Doctor Should See


What is Vitamin C?

Most writers use "vitamin C" and "ascorbic acid" interchangeably. However, ascorbic acid is but one form of vitamin C.

Technically vitamin C is the ascorbate ion (C6H7O6) so every form of vitamin C has this anti-scurvy factor. Vitamin C comes in many forms because the vitamin C part (C6H7O6) easily combines with other atoms and molecules. For example, the ascorbate fraction rapidly attaches to hydrogen, sodium, calcium, magnesium and potassium atoms.

All forms of vitamin C can be called ascorbates. Even the most common form of vitamin C, ascorbic acid, is hydrogen ascorbate (the ascorbate ion attached to a hydrogen atom).

Vitamin C Foundation Ascorbic acid is a weak acid; its acidity is about that of a cola soft drink. Vitamin C does not have to be acidic. It is also found in various alkaline forms, such as the mineral ascorbates sodium ascorbate, calcium ascorbate, magnesium ascorbate, and potassium ascorbate, etc.

Chirality

Ascorbate has different shapes in three-dimensional space. The different shapes of the ascorbate fraction have the same atoms, but the atoms are arranged differently, much like the right hand is the same but different from the left hand.

Vitamin C Foundation Chemists call the difference between the same molecules their chirality. Linus Pauling explained that there are exactly four different shapes (stereoisomers) the ascorbate ion can take: L-ascorbate, D-ascorbate, LD-ascorbate and DL-ascorbate.
Linus Pauling the chemist also told us that only the L-ascorbate shape has vitamin C activity, i.e. only the L- shape can cure the vitamin C deficiency disease scurvy.

What if All Vitamin C Isn't Created Equal?

Vitamin C - What do you Need?

"While known to scientists like myself, the public and most doctors are totally unaware that synthesizing vitamin C produces two very different molecules. These are: D-ascorbate and L-ascorbate. Almost all the vitamin C on the market is roughly a 50/50 mixture of the two. Only the L-ascorbate is biologically beneficial to the body. D-ascorbate is an irritant to the body, and there are indications that a lot of D-ascorbate could be detrimental to health.

Over the years that I have recommended vitamin C, many have complained that vitamin C irritates their stomach. Yet, when they take high-quality vitamin C, this doesn't happen. It's the D-ascorbate contaminant that's the problem. Those who are supplementing with regular commercial vitamin C need to know that half of what they are paying for is biologically useless, a waste of money and perhaps even detrimental. Another issue is that even vitamin C from natural sources degrades. For example, a fresh orange is almost all L-ascorbate. Once extracted to make orange juice, it will, in a matter of days, degrade to become a 50/50 mixture of D- and L-ascorbate" - Raymond Francis www.beyondhealthnews.com/wpnews/index.php/2013/09/vitamin-c-what-do-you-need

Vitamin C Foundation Approved™ products are DSM Quali-C™ certified L-ascorbate. See Quali-C Spec Sheet


Is Vitamin C Really a Vitamin?

Vitamin C Foundation Scientists are now using the more technically correct term ascorbate, instead of vitamin C, especially when referring to dosages higher than the 10 to 60 milligrams daily that prevent death from acute scurvy.

Most vitamins are readily available in food and are only required in minuscule amounts by the animals that eat the food. It is true that tiny amounts of vitamin C (around 10 milligrams daily) can keep you alive by preventing death from the vitamin C deficiency disease scurvy. Therefore, the RDA (60-90 mg) keeps most of us alive.

There is something different about vitamin C.

The intellectual argument whether vitamin C is more than just a vitamin is based on the theory of evolution. Genetic deletions are common, yet most plants and animals make their own vitamin C. Very few species have survived to the present day after losing their innate ability to make vitamin C.

According to British nutritionist Patrick Holford,

Vitamin C Foundation "Vitamin C, ascorbic acid C6H8O6, isn't a vitamin for most species. It is not a necessary component of the diet, at least for all mammals with the exception of guinea pigs, fruit eating bats, the red vented bulbul bird and primates - which includes us. All other species make their own." - Read full article: How Much Is Enough?

Another clue that we evolved to require more ascorbate than is in our food is the amount of vitamin C animals make for themselves: thousands of milligrams (not tens of milligrams), far more than nutritional authorities recommend.

High dosages of ascorbate have been found to be clinically effective and may cure many diseases and conditions, making the strong case that ascorbic acid (C6H8O6) is not a vitamin in the commonly used sense of the word.

Flashback: 86 Years Ago...

SYNTHETIC VITAMIN PRODUCES STRIKING UNEXPECTED CURES
September 22, 1934 (Science News)

"Synthetic vitamin C, called ascorbic acid, in its first actual use on medical patients is producing very striking and unexpected disease conquests, the British Association for the Advancement of Science was informed by Prof. A. Szent-Györgyi, the Hungarian chemist who played a major role in the artificial manufacture of this important vitamin.

The mouth disorder known as pyorrhea, a certain kind of hemophilia, which is a disease of bleeding, certain forms of hemorrhagic nephritis, and several other diseases against which medicine was helpless are seemingly being cured by ascorbic acid. Ascorbic acid is not a cure for hereditary hemophilia.

'This is the more striking since these pathological conditions have not been thought to be connected with lack of vitamin,' Prof. Szent-Györgyi explained. 'These curative effects suggest that humanity is suffering much more gravely from a lack of vitamin C than has hitherto been supposed.'

Disfiguring colorations of the skin brought on by illness are also made to disappear by ascorbic acid. Patients with Addison's disease, who have a yellow color, can be bleached out again by the use of this substance."

From the September 22, 1934, issue of Science News


Why Do We Need More Vitamin C than the RDA?

There is growing scientific evidence, as documented throughout these web pages, that taking more vitamin C than is recommended by medical authorities and government agencies can prevent and even treat a wide variety of human disorders; ranging from heart disease and stroke, to cancer, to diabetes, to viral and bacterial infections, as well as to slow premature aging.

Vitamin C Foundation The government's current recommended daily allowance for vitamin C is around 70 milligrams. (See our RDA)

The intriguing question is whether larger-than-recommended amounts of vitamin C improve the health of human beings?

Nobelist Linus Pauling was the world's foremost vitamin C expert. Pauling explained that there is a wealth of scientific research information that expands vitamin C's role past that of an ordinary vitamin.

Vitamin C Foundation There are now more than 100,000 studies, reports and peer-reviewed papers about vitamin C that have been published over the past 80 years. Surprisingly, medical students and nutritionists are not made aware of this research during their medical educations. - Owen Fonorow

Linus Pauling himself, after reviewing the research, supplemented 18,000 milligrams of ascorbic acid daily, and he recommended that every adult take at least 6000 milligrams (or 6 grams) to 18,000 milligrams (18 grams) every day.

The Vitamin C Foundation's daily recommendation (RDA) is 3000 milligrams.

Dr. Robert Cathcart, III, MD has used more then 200,000 milligrams daily treating severe viral infections as described in his original 1986 "Vitamin C: Titrating to Bowel Tolerance" paper.

Steve Hickey and Hiliary Roberts explain in Ridiculous Dietary Allowance why the current official recommendations are unscientific and inappropriate.

According to Linus Pauling, vitamin C deficiency is more common in human beings than generally believed.

The complete absence of vitamin C in the diet will cause death from the vitamin C deficiency disease scurvy. Nobelist Pauling felt that we are all dying a slow death from a low-grade form of scurvy.

It is a fact that Pauling and associates implicated a sub-clinical vitamin C deficiency, leading to a condition he called chronic scurvy, as the root cause of heart disease.

Cardiovascular diseases such as heart disease and stroke are the leading cause of death in the United States.

Pauling's Therapy for Heart Disease. The Cure?


Don't Tissues Saturate at 200 mg of Vitamin C?

The erroneous idea that 200 mg of vitamin C is all our bodies can use daily arose out of important research by the Mark Levine group at the National Institutes of Health (NIH).

The NIH papers were analyzed by pharmacology professors Steve Hickey, Ph.D. and Hilary Roberts, Ph.D., and the errors were communicated to the NIH and other authorities. After normal scientific channels failed, these UK scientists authored two important books detailing the errors in the NIH research conclusions.

Vitamin C Foundation The basic flaw in the NIH research was not accounting for the short half life of ascorbate in the blood plasma. Using the NIH's own numbers, Hickey and Roberts developed their Dynamic Flow theory.
For those interested in the details of why our blood plasma and tissues do not "saturate" at 200 mg daily, please refer to:

Vitamin C Foundation Apparently the Linus Pauling Institute is aware of the faulty NIH research, but not of the Hickey/Roberts rebuttal arguments.
One major implication of the Hickey/Roberts' Dynamic Flow theory is that taking 500 mg of vitamin C orally every 3 hours maintains the highest steady-state blood plasma concentrations.

Natural Vitamin C-Complex - Fact or Fiction?

"The old name for scurvy was scorbutes; so vitamin C, once identified, was quickly christened a-scorbutic acid; or ascorbic acid. Ignore the deluded ninnies that think ascorbic acid is something evil and not real vitamin C! It's as daft as saying H2O isn't water! And before you write to tell me: ascorbic acid is the name for both natural and synthetic vitamin C and BOTH work just fine, because they are identical. - Dr. Keith Scott-Mumby The Vitamin That Conquered The World!
Vitamin C Foundation

Is there really such a thing as natural vitamin C complex?

Such a complex can be defined, but it isn't vitamin C.

If such a complex really exists with vitamin C activity (minus ascorbic acid), this fact escaped the attention of all world scientists, including Linus Pauling. Such a complex is not reported in over 100,000 published studies, papers, reports and scientific articles regarding ascorbic acid (C6H8O6).

Vitamin C Foundation Vitamin C is defined as the substance that cures the deficiency disease scurvy. This separates the ascorbates (C6H7O6) from the ill-defined natural vitamin C complex. Note that any so-called natural complex, minus (C6H7O6) does not and cannot cure scurvy and, therefore, cannot be Vitamin C.

A. Szent-Györgyi's On the Nature of Vitamin C

Those who argue that a vitamin C complex exists, and is different from ascorbic acid, usually claim (falsely) that the Nobel scientist credited with isolating Vitamin C, Professor A. Szent-Györgyi, believed in the so-called natural C-complex. This rumor is based on early speculation and misquotes earlier writings by Dr. Szent-Györgyi.

Vitamin C Foundation "Ascorbic acid (vitamin C) is one of the important water soluble vitamins. It is essential for collagen, carnitine and neurotransmitters biosynthesis. Most plants and animals synthesize ascorbic acid for their own requirement. However, apes and humans can not synthesize ascorbic acid due to lack of an enzyme gulonolactone oxidase. Hence, ascorbic acid has to be supplemented mainly through fruits, vegetables and tablets." Read the full article "Vitamin C in Human Health and Disease is Still a Mystery? An Overview"
