Vitamin C, Titrating to Bowel Tolerance, Anascorbemia, and Acute Induced Scurvy
Robert F. Cathcart, III, Medical Hypotheses, 7:1359-1376, (1981).
Abstract
A method of utilizing vitamin C in amounts just short of the doses which
produce diarrhea is described (titrating to bowel tolerance). The amount of oral ascorbic acid tolerated by a patient without
producing diarrhea increases somewhat proportionately to the stress or toxicity
of his disease. Bowel tolerance doses of ascorbic acid ameliorate the
acute symptoms of many diseases. Lesser doses often have little effect on acute
symptoms but assist the body in handling the stress of disease and may reduce
the morbidity of the disease. However, if doses of ascorbate
are not provided to satisfy this potential draw on the nutrient, first local
tissues involved in the disease, then the blood, and then the body in general
become deplete of ascorbate (anascorbemia
and acute induced scurvy). The patient is thereby put at risk for complications
of metabolic processes known to be dependent upon ascorbate.
Introduction
Over the past ten-year period I have treated over 9,000 patients with
large doses of vitamin C (Cathcart 1, 2, 3, 4, 5).
The effects of this substance when used in adequate amounts
markedly alters the course of many diseases. Stressful conditions of any
kind greatly increase utilization of vitamin C. Ascorbate
excreted in the urine drops markedly with stresses of any m
If this massive draw on the small ascorbate
stores of the body is not fully satisfied, the condition of ANASCORBEMIA
results. The deficit of ascorbate probably starts in
the tissues directly involved in the disease and then spreads to other tissues
of the body. A condition of localized and then systemic acute scurvy is
produced. This acute induced scurvy leads to poor healing and ultimately to
complications involving other systems of the body.
Much of the original work with large amounts of vitamin C was done by Fred
R. Klenner, M.D. (6, 7, 8, 9)
of
Bowel Tolerance Method
In 1970, I discovered that the sicker a patient was, the more ascorbic
acid he would tolerate by mouth before diarrhea was produced. At least 80% of adult
patients will tolerate 10 to 15 grams of ascorbic acid fine crystals in 1/2 cup
water divided into 4 doses per 24 hours without having diarrhea. The
astonishing finding was that all patients, tolerant of ascorbic acid, can take
greater amounts of the substance orally without having diarrhea when ill or
under stress. This increased tolerance is somewhat proportional to the toxicity
of the disease being treated. Tolerance is increased some by stress (e.g.,
anxiety, exercise, heat, cold, etc.)(see FIGURE I).
Admittedly, increasing the frequency of doses increases tolerance perhaps to
half

1. REPRESENTATIVE DOSES TO TREAT ACUTE
SYMPTOMS OF DISEASE IN PATIENTS VERY TOLERANT TO ASCORBIC ACID
GRAMS ASCORBIC ACID ORALLY PER 24 HOURS
Note that disease symptom curves indicate very little effect on acute
symptoms until doses of 80-90% of bowel tolerance are reached. Perhaps it is
only near tolerance doses that the ascorbate is
pushed into the primary sites of the disease. 2) Suppression of symptoms in
some instances may not be total; but usually it is very significant and often
the amelioration is complete and rapid. 3) Hepatitis may require 30 to 100
grams.
Titrating To Bowel Tolerance
The maximum relief of symptoms which can be expected with oral doses of
ascorbic acid is obtained at a point just short of the amount which produces
diarrhea. The amount and the timing of the doses are usually sensed by the
patient. The physician should not try to regulate exactly the amount and timing
of these doses because the optimally effective dose will often change from dose
to dose. Patients are instructed on the general principles of determining doses
and given estimates of the reasonable starting amounts and timing of these
doses. I have named this process of the patient determining the optimum dose,
titrating to bowel tolerance. The patient tries to titrate between that amount
which begins to make him feel better and that amount which almost but not quite
causes diarrhea.
I think it is only that excess amount of ascorbate
not absorbed into the body which causes diarrhea; what does not reach the
rectum, does not cause diarrhea. It is interesting to know, when one speculates
on the exact cause of this diarrhea, that while a hypertonic solution of sodium
ascorbate is being administered intravenously, the
amount of ascorbic acid tolerated orally actually increases.
The 100 Gram Cold
When a person is ill the amount of ascorbic acid he can ingest without
diarrhea being produced increases somewhat proportionally to the severity or
the toxicity of the disease. A cold severe enough to permit a person to take
100 grams of ascorbic acid per 24 hours during the peak of the disease, I call
a 100 gram cold.
Individual Responses
Perhaps one of the most important principles in orthomolecular medicine is
biochemical individuality (18).
Every individual responds to substances differently. Vitamin C is no exception.
However, at least 80% of my patients tolerated ascorbic acid well. Admittedly,
there were relatively few older patients in my practice. Infants, small
children, and teen
For several years while I was treating only sick people with ascorbic
acid, I was unaware of the number of people who had nuisance problems with
maintenance doses. The tolerance of the sick person to ascorbate
is so high as to prevent many of the complaints one would have if he were well.
When ascorbic acid is prescribed to a sick person, the beneficial effect is
obvious enough so that few complain of the gas and diarrhea. With illness the
effects of an overdose do not last long because of the rapid rate of utilization.
It is important for the physician to understand the principles of treating
this vast m
Anascorbemia -- Acute Induced Scurvy
It is well established that certain symptoms are associated with an almost
total lack of vitamin C within the body. Symptoms of scurvy include lassitude, malaise,
bleeding gums, loss of teeth, nosebleeds, bruising, hemorrh

I had assumed that much of this ascorbate was
used for functions somehow directly related to neutralizing the toxicity of
viral and bacterial diseases. When ill, one has the internal sense that
something of this nature is happening when bowel tolerance is approached.
Recently, however, I had the personal experience of ingesting 48 grams in an
hour and a half when I had a sudden hay fever reaction to roses. Upon
withdrawal from the roses tolerance dropped rapidly to
normal. This experience plus my experiences with many patients under emotional stress, would indicate that the adrenals are capable of
utilizing large amounts of ascorbate with benefit if
it is made available.
This draw on ascorbate, from whatever source,
lowers the blood level of ascorbate to a negligible
level. I have coined the term anascorbemia for this
condition. If this anascorbemia is not rapidly
rectified by the oral administration of bowel tolerance doses of ascorbic acid
or by intravenous administration of ascorbate, the
remainder of the body is rapidly depleted of ascorbate
and put at risk for disorders of the metabolic processes dependent upon vitamin
C.
The following problems should be expected with increased incidence with
severe depletion of ascorbate: disorders of the
immune system such as secondary infections, rheumatoid arthritis and other coll
Not only is there the theoretical probability that these types of
complications associated with infections or stresses could result from ascorbate depletion, but there was a conspicuous decrease
in the expected occurrence of complications in the thousands of patients
treated with oral tolerance doses or intravenous doses of ascorbate.
This impression of marked decrease in these problems is shared by physicians
experienced with the use of ascorbate such as Klenner (8,
9) and Kalokerinos (22).
The Missing Stress Hormone
Stone (11) has
described the genetic defect whereby the higher primates lost the ability to
synthesize ascorbate. This defect is caused by a
mutated defective gene for the liver enzyme, L-gulonolactone
oxidase. The higher mammals (except for the higher
primates) developed a feedback mechanism which increases ascorbate
synthesis under the influence of external and internal stresses (23).
There are many well-established functions of vitamin C that help in the
handling of stress. When stressed, the higher mammals can augment these
functions by this feedback mechanism. For the higher primates, including
humans, ascorbate can amount to the MISSING STRESS
HORMONE (4).
I have seen strong clinical evidence that not only does the bowel
tolerance to ascorbate increase under stress but that
fully satisfying that potential use for ascorbate
markedly reduces secondary diseases and complications following stress or
primary disease. Since 1970, with teaching the bowel tolerance method of
determining proper ascorbic acid doses to patients, I have not had to
hospitalize a single patient for an acute viral disease or a complication from
such a disease if the patient utilized the method. In some cases, such as with
three cases of viral pneumonia, it was necessary to utilize intravenous ascorbate. Admittedly, I have been lucky because no patient
has arrived with such severe symptoms as to necessitate immediate
hospitalization. There have been many patients where there was no question that
they would have required hospitalization in a very short period of time had not
ascorbate been administered. Some patients not quite
taking bowel tolerance doses, but taking significantly large doses of ascorbate, would not have as dramatic suppression of acute
symptoms but would, nevertheless, avert complications.
Mononucleosis
Acute mononucleosis is a good example because there is such an obvious
difference between the course of the disease, with and without ascorbate. Also, it is possible to obtain laboratory di
Many cases do not require maintenance doses for more than 2 to 3 weeks.
The duration of need can be sensed by the patient. I had ski patrol patients
back skiing on the slopes in a week. They were instructed to carry their boda b
Hepatitis
Acute cases of infectious hepatitis have responded dramatically. Cases
included two orthopaedic surgeons who probably
acquired the disease pricking their hands at surgery and being inoculated with
a patient's blood. With ascorbate treatment
laboratory tests including the SGOT, SGPT, and bilirubins
indicated rapid reversal of the disease. In one of these cases, with the doctorpatient and his treating physicians having difficulty
believing that the ascorbate was responsible for the
improvement, the ascorbate was discontinued. The
condition of the patient rapidly deteriorated. The patient's wife took charge
and doled out the ascorbate;
Usually oral bowel tolerance doses will reverse hepatitis rapidly. Stools
regularly return to normal color in 2 days. It generally takes about 6 days for
the jaundice to clear, but the patient will feel almost well after 4 to 5 days.
Because of the diarrhea caused by the disease, intravenous ascorbate
may need to be used in very severe cases. Often large doses of ascorbic acid,
taken orally despite diarrhea, will cause a paradoxical cessation of the
diarrhea.
Morishige has demonstrated the effectiveness of ascorbate in preventing hepatitis from blood transfusions (24).
Unsick
The phenomenon of symptoms returning repeatedly if the ascorbate
is not continued in high doses is most convincing. It is possible to have
symptoms come and go many times. In fact, there is often a feeling when
titrating to bowel tolerance that symptoms are beginning to return just before
taking the next dose.
Often a patient will sense that he is probably catching some viral disease
and that he is in need of large doses of ascorbic acid. If he is experienced in
taking ascorbic acid he may be able to suppress more than 90% of the symptoms.
He feels that he should take large amounts of ascorbate,
does not feel quite right, and may have peculiar mild symptoms. I call this
condition UNSICK. Recognition of this state is important because it can be
mistaken for more serious conditions.
Intravenous And
Intramuscular Ascorbate
Symptoms from acute viral diseases can most frequently be more permanently
eliminated with intravenous sodium ascorbate. While
it is true that tolerance doses of oral ascorbate
will usually eliminate complications of acute viral diseases; at times, such as
with certain cases of influenza, the large amount of oral ascorbate
necessary to suppress symptoms over a period of a week or more,
sometimes makes intravenous ascorbate desirable.
Clinically large amounts of ascorbate used
intravenously are virucidal (2, 5, 7, 8).
The sodium ascorbate used intravenously and
intramuscularly must contain no preservatives. Usually there is only a small
amount of EDTA in the preparation to chelate trace
amounts of copper and iron which might destroy the ascorbate.
Solutions containing sodium ascorbate 250 or 500 mgm per cc can be obtained. The 250 mgm
solutions may be used in young children intramuscularly in doses usually 350 mgm/kg body weight up to every 2 hours. When the volume of
the material becomes too great for intramuscular injections, then the
intravenous route should be used. Inadequate doses will be ineffective. Quite
frequently a child initially refusing oral ascorbate
will cooperate after injections if given the alternative. While this method of
persuasion seems cruel, it is better than the complications which might
otherwise occur. These intramuscular injections can be used in a crisis
situation. Kalokerinos (22) describes cases where
certain death in infants already in shock has been averted by emergency
intramuscular ascorbate.
For intravenous solutions concentrations of 60 grams per liter are made
with the 250 or 500 mgm/cc sodium ascorbate
diluted with Ringer's lactate, 1/2N saline, 1N saline, D5W, or distilled water
for injection. I prefer the latter, but one has to be absolutely sure that an
error is not made and pure water given. Ascorbate is
more efficient intravenously than orally probably because chemical processes in
the gut destroy a percent
I have not yet seen a case of phlebitis develop as a result of ascorbate administration. This rarity of phlebitis possibly
suggests that this condition sometimes has something to do with ascorbate depletion.
Frequently I have the patient take oral doses of ascorbic acid at the same
time he is taking intravenous sodium ascorbate. Bowel
tolerance is actually increased by concomitant use of intravenous ascorbate. Care and experience is necessary with
concomitant use because tolerance drops precipitously when the intravenous
infusion is discontinued.
Bacterial Infections
Ascorbic acid should be used with the appropriate antibiotic. The effect
of ascorbic acid is synergistic with antibiotics and would appear to broaden
the spectrum of antibiotics considerably. I found that penicillin-K orally or
penicillin-G intramuscularly used in conjunction with bowel tolerance doses of
ascorbic acid would usually treat infections caused by organisms ordinarily
requiring ampicillin or other more modern synthetic penicillins. Cephalosporins were
used in conjunction with ascorbic acid for staphylococcus infections. The
combination of tetracycline and ascorbate was used
for nonspecific urethritis; however, patients who had
previously repeated recurrences of nonspecific urethritis
found they were free of the disease with maintenance doses of ascorbate. I am not sure that the tetracycline was
necessary even in the acute cases, but it was used for legal reasons. Some
other cases of unknown etiology such as two cases of Reiter's disease and one
case of acute anterior uveitis also responded
dramatically to ascorbate.
A most important point is that patients with bacterial infections would
usually respond rapidly to ascorbic acid plus a basic antibiotic determined by
initial clinical impressions. If cultures subsequently proved the selection of
antibiotic incorrect, usually the patient was well by that time.
In the case of a 45-year-old man who had developed osteomyelitis
of the 5th metacarpal of the right hand following a cat bite, a partial
amputation of the hand had been recommended and surgery scheduled. Consultants
This case illustrates the frequent problem of an indolent infection with
an organism non-responsive to the most sophisticated antibiotic treatment which
then may respond rapidly to treatment with intravenous ascorbate.
Treating simultaneously with the appropriate antibiotic plus ascorbate has the additional advant
Vitamin C And Allergy
Patients seemed not to develop their first allergic reaction to penicillin
when they had taken bowel tolerance ascorbate for
several doses. Among the several thousand patients given penicillin, two cases
of brief rash were seen in patients who had taken their first dose of
penicillin along with their first dose of ascorbate.
If one understands the reasons for bowel tolerance doses of ascorbate,
it is obvious that these patients were not as yet "saturated." I saw
three patients who had taken penicillin without ascorbate
who had developed an urticarial rash. These cases
rapidly responded to oral ascorbic acid. Only a single dose of antihistamine
was usually used. I would have anticipated longer reactions in most of these
cases. I saw one case of a delayed serum sickness type of penicillin reaction
in a ten-year-old girl who had not taken ascorbate
previously. The rash in this patient did not immediately respond to ascorbic
acid. The rash took about two weeks to completely resolve; however, if the ascorbate was not taken regularly to tolerance, the rash
would worsen. It was difficult to maintain high doses in this patient.
Patients who had known-previous-allergic reactions to penicillin were
never given the antibiotic anticipating that vitamin C would protect them. I
suspect that the deficit of body ascorbate produced
by disease may have something to do with malfunction of the immune system and
the development of allergies. However, whether ascorbate
may give some protection from an antibiotic known previously to cause an
allergic reaction in a patient, when subsequent reactions might involve
anaphylaxis, is a question which must be approached very carefully.
Certainly, inadequate doses of ascorbate could be
disastrous.
Patients with mononucleosis, untreated with ascorbate,
have a very high incidence of allergic reaction to penicillin. It is
interesting that this same disease seems to cause some of the highest bowel
tolerances of any disease.
As can be seen from the previous discussion of the increasing bowel tolerance
phenomenon, there is undoubtedly increased utilization of ascorbate
under stressful conditions. If this increased utilization creates a deficit,
there may be malfunctions of various systems of the body such as the immune
system which are dependent on ascorbate. Therefore,
it should not be surprising that certain malfunctions of the immune system and
adrenal glands associated with stress might be ameliorated by ascorbate.
Hay fever is controlled in the m
Asthma is most often relieved by bowel tolerance doses
of ascorbate. A child regularly having asthmatic
attacks following exercise is usually relieved of these attacks by large doses
of ascorbate. So far all of my patients having asthmatic
attacks associated with the onset of viral diseases have been ameliorated by
this treatment.
Large clinical studies will be necessary to prove this point, but for now
prudent practice would be to take large doses ofascorbate
when stressed or when ill.
This theory begins to make some sense of the observation that many
patients will develop allergic disorders or other diseases following
combinations of stress, disease, and malnutrition. Immunologists should be
particularly interested in the control of these allergic problems and
particularly the dramatic responses of cases of ankylosing
spondylitis, Reiter's disease, and acute anterior uveitis. All three of these problems have a high
association with the HLA-B27 antigen. The possibility that ascorbate
might have some value in controlling the immune response at the gene level
should be thoroughly investigated because there could be some basic
implications in histocompatibility (graft
acceptance), cancer control, and destruction of foreign invaders. Ascorbate would appear to help stabilize some homeostatic
mechanisms.
Candida Albicans
Yeast infections occur less frequently in patients treated with
antibiotics if bowel tolerance doses of ascorbic acid are simul-
taneously used. Ascorbic acid seems to reduce the
systemic toxicity considerably but does not eliminate the primary infection. It
has been helpful to patients with allergic problems secondary to candida.
Fungus Infections
Although ascorbic acid should be given in some form to all sick patients to
help meet the stress of disease, it is my experience that ascorbate
has little effect on the primary fungal infections. Systemic toxicity and
complications can be reduced in incidence. It may be found that appropriate

Anyone who has done animal surgery other than on humans is impressed by
the rapid recovery rate. Humans loaded with ascorbate

amounts never exceeding several grams. I predict that reimplantations

I have avoided the treatment of cancer patients for legal reasons;

Acute herpes infections are usually ameliorated with bowel tolerance doses

zinc should be done.
For chronic herpes, intravenous ascorbate may
also be of benefit.

Maintenance Doses
Maintenance doses are established by the patient taking bowel tolerance
doses 6 times a day for at least a week. He observes if there is any unexpected
benefit such as clearing of sinuses, decrease in allergies, increase in energy,
etc. Should any chronic problem be benefited, then the dose is decreased to the
minimum amount producing the effect. Otherwise a dose such as 4 to 10 grams a
day divided in 3 to 4 doses is recommended.
In addition, the patient is told to increase the dose on stressful days.
If a patient well tolerates ascorbic acid dissolved in water, then after a
short period of time his taste will begin to regulate the dos
Patients who take ascorbate in large amounts
over a long period of time should probably suppliment
with vitamin A and a multiple mineral preparation. The "Fortified
Formulation for Nutritional Insurance" of Roger Williams (29) is recommended as a
base.
Complications
It is my experience that ascorbic acid probably prevents most kidney
stones. I have had a few patients who had had kidney stones before starting
bowel tolerance doses who have subsequently had no more difficulty with them.
Acute and chronic urinary tract infections are often eliminated; this fact may
remove one of the causes of kidney stones. Six patients have had mild pain on
urination; five of these patients were over fifty and none had stones.
Three out of thousands had a light rash which cleared with subsequent
doses. It was difficult to evaluate the cause of this because of concomitant
infections. Several patients had discoloration of the skin under jewelry of
certain metals. A few patients complaining of small sores in the mouth with the
taking of small doses of ascorbate had them clear
with bowel tolerance doses.
Patients with hidden peptic ulcers may have pain, but some are benefited.
Mineral ascorbates can be used for maintenance doses
in these cases. Two patients who had mild epigastric
discomfort with maintenance doses of ascorbic acid who
after being given ascorbate by vein for several days
were then able to tolerate the acid orally.
It is my experience that high maintenance doses reduce the incidence of
gouty arthritis. I have not seen difficulties with giving large amounts of
ascorbic acid to patients with gout. Almost all my patients have been
Caucasian, so I have no comment on the report that ascorbate
can cause certain blood problems in certain non-white groups (30).
There has been no clinical evidence as Herbert and Jacob (31) suspected that
ascorbic acid destroys vitamin B12.
If maintenance doses of ascorbic acid in solution are used over very long
periods of time I would rinse the teeth after each dose. I would not brush my
teeth with calcium ascorbate.
There is a certain dependency on ascorbic acid that a patient acquires over
a long period of time when he takes large maintenance doses. Apparently,
certain metabolic reactions are facilitated by large amounts of ascorbate and if the substance is suddenly withdrawn,
certain problems result such as a cold, return of allergy, fatigue, etc.
Mostly, these problems are a return of problems the patient had before taking
the ascorbic acid. Patients have by this time become so adjusted to feeling
better that they refuse to go without ascorbic acid. Patients do not seem to
acquire this dependency in the short time they take doses to bowel tolerance to
treat an acute disease. Maintenance doses of 4 grams per day do not seem to
create a noticeable dependency. The m

It would be possible to conduct a double blind study on intravenous ascorbate; however, doses would have to be determined by
someone experienced with this method.
Part of the difficulty many have with understanding ascorbate
is that claims for its benefits seem too many. Most of these clinical results
merely indicate that large doses of ascorbate augment
the healing abilities of the body already known to be dependent upon minimal
doses of ascorbate.
I anticipate that other essential nutrients will be found being utilized
at unsuspectedly rapid rates in disease states. Compli- cations caused by
failures in systems dependent upon those nutrients will be found. The m
