Ascorbate:
Lies, Myths and Half-Truths
Over the years and to this day, ascorbate has been and continues to be the
target of many attacks and deprecations from numerous sources. But if examined
closely, the common thread running through all these allegations of ascorbate’s
“harmfulness” is that they arise out of vested interest. Diverse though
they may be, they all have in common a willingness to spread rumors and hearsay
to create fear, uncertainty, and doubt about ascorbate. Here they are:
- Researchers who know which side their bread is buttered on
vis-à-vis research funding. Their careers come to a standstill if they
cannot get research grants, usually from drug companies who know the
cost-effectiveness of manipulating research outcomes and suppressing results
injurious to their profits.
- Medical practitioners who cannot deviate too far from orthodox
treatments out of fear, from medical review boards and especially
malpractice lawyers.
- Pharmaceutical and medical technology corporations that have zero
to negative interest in preventative health, and are actively hostile to any
perceived competition that would cut into their profits or market share.
Never mind that their patented medicines are terrifically expensive, are
usually toxic and loaded with side-effects: this is about business,
not health.
- Publishers and editors whose livelihoods depend on not antagonizing
the entities who submit articles or the advertisers who pay the bills;
- Assorted fools and buffoons who are by nature contentious and
contrary, and just cannot stand to consider facts at odds with their skewed
worldview. They can actually read
the articles about ascorbate and its benefits, but are compulsively,
psychopathically disbelieving of the conclusions. So they dedicate their
spare time, which is evidently excessive, tearing down great researchers and
clinicians and their discoveries.
- Wishy-washy, ignorant airheads who cannot trouble themselves to
even discover the facts. Herbalists and wacko remedy peddlers often fall
into this category.
The bottom line is that the enemies of ascorbate (and indeed of
orthomolecular modalities in general) all are looking after their bottom
line. Quite simple, really.
The list below summarizes the major lies, myths and half-truths told about
ascorbate.
- ascorbate destroys vitamin B12
- ascorbate causes kidney stones
- ascorbate causes uric-acid urinary-tract stones and gout
- ascorbate causes DNA damage (leading to cancer)
- ascorbate causes or exacerbates gastric uncers
- ascorbate causes thrombosis (abnormal internal blood clotting)
- ascorbate causes diabetes
- ascorbate causes rashes, nausea or other gastric upset, abdominal cramps,
headaches, fatigue, and diarrhea
- ascorbate interferes with the metabolism of other nutrients (eg. sodium
and iron) causing either overload or depletion
- ascorbate interferes with medical tests, such as diabetes, anemia and
occult blood-in-stool tests
- ascorbate causes cancer
- ascorbate causes atherosclerosis
- ascorbate is only an antioxidant (see Szent-Györgyi & Stone)
- ascorbate is only a vitamin (micronutrient); typical daily diets supply
“enough” ascorbate
- The US RDA of 60 mg ascorbate/day is adequate
- Intakes in excess of 40/65/200 mg/day are excreted in the urine
- Only humans and primates, guinea pigs, bulbuls and fruit bats need dietary
ascorbate
- “Natural Vitamin C” is more effective than the cheaper synthetic form of
ascorbate
- ascorbate is worthless against the common cold
- ascorbate is worthless against cancer
- people with G6PD enzyme deficiencies cannot be administered intravenous
ascorbate
- ascorbate supplants the immune system by destroying bacteria and viruses
that normally generate antibodies
So let us consider in turn each of these whoppers, hooey and misconceptions:
- Myth: ascorbate destroys vitamin B12
Presented by V. Herbert and E. Jacob and eagerly printed in the
J.A.M.A. (1974, 230:241-242), this flawed test-tube study was quickly
refuted by numerous reliable research reports: M. Afroz (J.A.M.A.1974,
233:3, 246); H.L. Newmark (Am J Clin Nutr 1976, 29:6, 645-649);
H.P.C. Hogencamp (Am J Clin Nutr 1980, 33:1, 1-3); M. Marcus et al (Am
J Clin Nutr 1980, 33:137-143); M. Marcus (Am J Clin Nutr
1981, 34:1622-1624).
- Myth/Half-Truth: ascorbate causes kidney stones:
The origins of this myth are not too obscure, but its persistence is a
mystery. There is no conclusive clinical evidence that high intake of
ascorbate is firmly linked to oxalate kidney stones or to large increases in
urinary oxalate spillage. For most people, there is simply no significant
connection: M.P. Lamden & G.A. Chrystowski (Proc Soc Exp Biol Med,
85:1, 190-192, Jan 1954), K. Schmidt et al (Am J Clin Nutr 34:3,
305-311, March 1981), F. Erden et al (Acta Vitamin Enzym 7:1-2,
123-130, 1985) reported either insignificant or very low increases in
urinary oxalate after taking ascorbate.
There have been scattered, sparsely-reported anecdotes of unusual
stone-formers (e.g. M.H. Briggs et al, Med J Australia 2:1, 48-49, 7
July 1973) whose urinary oxalate increased unusually when taking large
amounts of ascorbic acid, and a few other reports of known stone-formers
whose urinary oxalate dropped when ascorbate was stopped (e.g. D.A. Roth et
al J.A.M.A., 237:8, 768, 21 Feb 1977). But these patients had a
history of stones before taking ascorbate, and the studies did
not rule out contributions of common dietary sources of oxalate (coffee,
tea, beans, spinach, oranges etc.). The tenor of most such studies seems
alarmist, apparently aimed at creating panic over the “dangers” of
ascorbate.
For the rare but unfortunate stone-formers out there, awareness of this
biochemical peculiarity and consequent nutritional counseling by a competent
practitioner should already be part of day-to-day living. Ascorbate
advocates generally recommend that ascorbic acid be avoided, taking instead
sodium ascorbate or other mineral-complexed ascorbate. In any case dietary
ascorbate is not the biggest problem here.
Complicating matters is that the notion that high-oxalate excretors are
necessarily stone-formers (and vice versa) is not borne out clinically,
with inconsistencies and contradictions between hypothesis and observation.
On the one hand, there is zero clinical evidence showing that, with
people who do not already have a kidney stone problem, ascorbate is even
remotely associated with stone formation. On the other hand, soft water, low
magnesium, excess sugar, chronic dehydration, and B1- and B6-vitamin
deficiencies (L. Hagler et al, Am J Clin Nutr 26:6, 882-889, August
1973; also see Curhan 1999) definitely are
associated with stones.
So maybe a lot of researchers have been barking up the wrong tree for way
too long. Many people over many years have really wanted ascorbate to be the
culprit here, but they just cannot prove a connection. All this obsessing
over ascorbate and kidney stones is old news and should stop now. Time to
move on.
- Myth: ascorbate causes uric-acid urinary-tract
stones and gout
This myth originated with dire speculations issued by H.B. Stein
et al (Ann Internal Med 84:4, 385-388, Apr 1976), who grudgingly
observed that blood uric acid levels did drop, with increased urinary
excretion, after taking 4-8 gram doses of ascorbic acid. But then they
warned—without evidence—that predisposed individuals could have
problems with ascorbic acid-mobilized uric acid causing gout or renal
calculi.
There is just no clinical evidence to support this alarmist myth. As
with oxalate kidney stones, there are other dietary considerations, in this
case an excess of purine-rich foods, sugars and alcohol, which are
clinically far more relevant in uric-acid problems. Another
ascorbate-hostile speculation down in flames.
(BTW eating a good quantity of cherries is a widely-known anecdotal
but effective folk remedy for gout. Since cherries are not patentable, one
does not suppose we’ll soon see any corporate research into cherries’ active
anti-gout substances.)
- Myth: ascorbate causes DNA damage (leading to
cancer)
This ludicrous myth was started principally by I.D. Podmore et al
(Nature
392:559, 1998) and abetted by S.H. Lee et al (Science 292:2083-2086,
2001). Small doses of 200 mg/day cause cancer! the press blared. This
hooey is particularly illogical and unsupportable, for the following
reasons*:
- Contradictions in assessing DNA-oxidation effects: Podmore
claimed that 8-oxyguanine (a strong mutagen) was decreased by ascorbate
supplementation, whereas 8-oxoadenine (a weak mutagen) was increased.
Podmore and the press jumped on the latter increase instead of making
the logical conclusion that overall mutagenicity was decreased by
ascorbate.
- Epidemiological evidence: over 100 studies have shown that
ascorbate intake is inversely correlated to many cancer types.
- Negative contradictory studies: at least six studies in
2000-2001 disprove any causation between ascorbate intake and DNA
damage.
- Common sense and animal evidence: since most animals make their
own ascorbate, usually in amounts greater than the alleged “DNA damage
threshold”, then animal life on Earth should have long since died of
self-inflicted DNA damage. Yeah, right. And anyway, the tens of millions
of people who have taken multigram doses of ascorbate for years or
decades (like me, since 1977 - ed.) are not especially known as
walking cancer cases with crisped DNA.
It is amusing but sad that as soon as a new kind of flashy bioassay
becomes widely available, some clown will attempt to misuse it to confirm
the evils of ascorbate.

- Myth: ascorbate causes or exacerbates gastric
uncers
This myth is inexplicable, with absolutely no clinical studies in
evidence to back it up. On the contrary, numerous studies since the 1940s
have demonstrated that most ulcer patients needing surgery actually suffer
from ascorbate deficiency bordering on scurvy. More ascorbate, not
less!
- Myth: ascorbate causes thrombosis (abnormal
internal blood clotting)
No.
- Myth: ascorbate causes diabetes
No. On the contrary, it can help type I (IDDM) diabetics reduce
insulin dosage, and type-II (NIDDM) diabetics manage the condition
dietarily.
- Myth/Half-Truth: ascorbate causes rashes, nausea
or other gastric upset, abdominal cramps, headaches, fatigue, and diarrhea
There have been no systematic studies addressing the side-effects
of oral ascorbate intakes, excessive or otherwise. Most comments about
side-effects or patient discomfort are made in passing, with little
recording or formal presentation of findings. Such reports must then be
termed anecdotal, a class of communication sneeringly dismissed by
ascorbate’s detractors when considering positive ascorbate therapies. But to
consider the so-called ascorbate side-effects:
- Rashes, nausea: ascorbate preparations, both oral and
injectible, have historically contained sulfites as preservatives. Many
people are known to be sulfite-sensitive, with symptoms like these. Most
modern preparations are more stable and need no preservatives. Next...
- “Gastric upset”: rather unspecified here, hm? Next...
- Abdominal cramps: which quadrant? Accompanied by belching or
flatulance? What was the ascorbate taken with food? Was the patient
tested for allergies to same? Was patient anxious? Any details? No?
Next...
- Headaches, fatigue: maybe sulfites again, but all unspecified
in any case. Did patient have a history of these complaints? Next...
- Diarrhea: finally a hit. “Large” doses of ascorbic acid can
cause loose bowels. But biochemical individuality, stress and illness
make it impossible to define “large”. Five grams might cause loose
bowels in a healthy 20-year old athelete, but a 50-gram dose might have
no bowel effects whatsoever in a 60-year old cancer patient who has been
taking such doses for months.
NB the acidic form of ascorbate, ascorbic acid, tends to cause bowel
effects more readily than the sodium ascorbate or other reacted
ascorbates. Parenteral (such as intravenous) sodium ascorbate is not
observed to cause bowel effects.
Also, increased urination (diuresis) is sometimes observed large oral
doses. No biggie.
