"Varying the concentrations of substances normally present in
the human body may control mental disease." - Linus Pauling
"The methods principally used now for treating patients with mental
disease are psychotherapy (psychoanalysis and related efforts
to provide insight and to decrease environmental stress), chemotherapy
(mainly with the use of powerful synthetic drugs, such as chlorpromazine,
or powerful natural products from plants, such as reserpine),
and convulsive shock therapy (electroconvulsive therapy, insulin
coma therapy, pentylenetetrazol shock therapy). I have reached
the conclusion that another general method of treatment, which
may be called orthomolecular therapy, may be found to be of great
value, and may turn out to be the best method of treatment for
many patients." - Linus Pauling, Science, April 19, 1968, p. 265
The author defines orthomolecular psychiatry as the achievement
and preservation of good mental health by the provision of the
optimum molecular environment for the mind, especially the optimum
concentrations of substances normally present in the human body,
such as the vitamins. He states that there is sound evidence for
the theory that increased intake of such vitamins as ascorbic
acid, niacin pyridoxine, and cyanocobalamin is useful in treating
schizophrenia. The negative conclusions of APA Task Force Report
7, Megavitamin and Orthomolecular Therapy in Psychiatry, he says,
result not only from faulty arguments and from a bias against
megavitamin therapy but also from a failure to deal fully with
orthomolecular therapy in psychiatry- Three psychiatrists comment
on Dr. Pauling's presentation.
Orthomolecular psychiatry is the achievement and preservation
of mental health by varying the concentrations in the human body
of substances that are normally present, such as the vitamins-
It is part of a broader subject, orthomolecular medicine, an important
put because the functioning of the brain is probably more sensitively
dependent on its molecular composition and structure than is the
functioning of other organs (1) . After having worked for a decade
on the hereditary hemolytic anemias, I decided in 1954 to work
on the molecular basis of mental disease. I read the papers and
books dealing with megavitamin therapy of schizophrenia by Hoffer
and Osmond (2,4) as well as the reports on studies of vitamins
in relation to mental disease by Cleckley and Sydenstricker (5,6)
and others. In the course of time I formulated a general theory
of the dependence of function on molecular structure of the brain
and other parts of the body and coined the adjective "orthomolecular"
to describe it (1).
There is no doubt that the mind is affected by its molecular environment.
The presence in the brain of molecules of LSD, mescaline, or some
other schizophrenogenic substance is associated with profound
psychic effects. Mental manifestations of avitaminosis have been
reported for several vitamins. A correlation of behavior of school
children with concentration of ascorbic acid in the blood (increase
in "alertness" or "sharpness" with increase in concentration)
has been reported by Kubala and Katz (7). A striking abnormality
in the urinary excretion of ascorbic acid after an oral loading
dose was reported for chronic schizophrenics by VanderKamp (8)
and by Herjanic and Moss-Herjanic (9). My associates and I (10)
carried out loading tests for three vitamins on schizophrenic
patients who had recently been hospitalized and an control subjects.
The percentage of schizophrenic patients who showed low urinary
excretion of each vitamin was about twice as great as that of
the controls: for ascorbic acid, 74 percent of the schizophrenic
patients showed low urinary excretion versus 32 percent of the
controls; for niacinamide, 81 percent versus 46 percent; and for
pyridoxine, 52 percent versus 24 Percent. The possibility that
the low values in urinary excretion of thew vitamins for schizophrenic
patients resulted from poor nutrition is made unlikely by the
observation that the numbers of subjects low in one, two, or all
three vitamins corresponded well with the numbers calculated for
independent incidence.
There are a number of plausible mechanisms by which the concentration
of a vitamin may affect the functioning of the brain. One mechanism,
effective COT vitamins that serve as coenzymes, is that of shifting
the equilibrium for the reaction of apoenzyme and coenzyme to
give the active enzyme. An example is the effectiveness of cyanocobalamin
(vitamin B12) given in amounts 1,000 times greater than normal
to control the disease methylmalonic aciduria (11-14). About half
of the patients with this disease are successfully treated with
megadoses of vitamin B12 . In these patients a genetic mutation
has occurred and an altered apoenzyme that has a greatly reduced
affinity for the coenzyme has been produced. Increase in concentration
of the coenzyme can counteract the effect of the decrease in the
value of the combining constant and lead to the formation of enough
of the active enzyme to catalyze effectively the reaction of conversion
of methylmalonic acid to succinic acid.
In the human population there may be several alleles of the gene
controlling the manufacture of each apoenzyme; in consequence
the concentration of coenzyme needed to produce the amount of
active enzyme required for optimum health may well be somewhat
different for different individuals- In particular, many individuals
may require a considerably higher concentration of one Or more
coenzymes than other people do for optimum health, especially
for optimum mental health. It is difficult to obtain experimental
evidence for gene mutations that lead to only small changes in
the properties of enzymes. The fact that genes that lead to large
and more easily detectable changes in the properties of enzymes
occur, as in individuals with methylmalonic aciduria, for example,
suggests that mutations that lead to small changes also occur.
Significant differences in enzyme activity in different individuals
have been reported by many investigators, especially by Williams
[15], who has made many studies of biochemical individuality.
It is likely that thorough studies of enzymes would show them
to be similar to the human hemoglobins. A few of the abnormal
human hemoglobins, most of which involve only the substitution
of one amino-acid residue for another in either the alpha chain
or the beta chain of the molecule, differ greatly in properties
from normal adult hemoglobin, leading to serious manifestations
of disease.
It was in the course of the study of one of these diseases, sickle
cell anemia, that the first abnormal hemoglobin was discovered
(16). Most of the abnormal human hemoglobins, however. differ
from normal hemoglobin in their properties to only a small extent,
so that there is no overt manifestation of diseaseThere is, nevertheless,
the possibility that even the small changes in properties of an
abnormal hemoglobin associated with a mild hemoglobinopathy will
have deleterious consequences. An example is the intolerance to
sulfa drugs associated with the substitution of arginine for histidine
in the locus 58 in the alpha chain or 63 in the beta chain. It
is likely that individual differences in enzyme activity will
in the course of time be shown to be the result of differences
in the amino-acid sequences of the polypeptide chains of the apoenzymes.
More than 100 abnormal human hemoglobins are now known, and the
human population may be expected to be similarly complex with
respect to many enzymes, including those involved in the functioning
of the brain. A tendency to schizophrenia is probably polygenic
in origin. I have suggested (1) that the genes primarily involved
in this tendency may well be those which regulate the metabolism
of vital substances such as the vitamins.
Some vitamins are known to serve as coenzymes for several enzyme
systems. We might ask if the high concentration of coenzyme required
to produce the optimum amount of one active enzyme might not lead
to the production of far too great an amount of another active
enzyme. The answer to this question is that the danger is not
very great. For most enzymes the concentration of coenzyme and
the value of the combination constant are such that most (90 percent
or more) of the protein is converted to active enzyme. Accordingly,
a great increase in concentration would increase the amount of
most active enzymes by only a few percentage points, whereas it
might cause a great increase for a mutated enzyme.
The Orthomolecular Treatment of Schizophrenia
In the book Orthomolecular Psychiatry: Treatment Of Schizophrenia
(17) my colleagues and I pointed out that the orthomolecular treatment
of schizophrenia involves the use of vitamins (megavitamin therapy)
and minerals; the control of diet, especially the intake of sucrose;
and, during the initial acute phase, the use of conventional methods
of controlling the crisis, such as the phenothiazines. The phenothiazines
are not, of course, normally present in the human body and are
not orthomolecular. However, they are so valuable in controlling
the crisis that their use is justified in spite of their undesirable
side effects.
Hawkins (18) stated that his initial combination of vitamins for
the treatment of schizophrenia was I gin. of ascorbic acid, I
gm, of niacinamide, 50 mg. of pyridoxine, and 400 I.U. of vitamin
E four times a day. Other vitamins may also be given. A larger
intake, especially of niacinamide or niacin may be prescribed;
the usual amount seems to be about 8 gm. a day after an initial
period on 4 gm. a day.
The vitamins, as nutrients or medicaments, pose an interesting
question. The question is not, Do we need them? We know that we
do need them, in small amounts, to stay alive. The Teal question
is, What daily amounts of the various vitamins will lead to the
best of health, both physical and mental? This question has been
largely ignored by medical and nutritional authorities.
Let us consider schizophrenia, Osmond (19) stated that about 40
percent of schizophrenics hospitalized for the first time are
treated successfully by conventional methods in that they are
released and not hospitalized a second time. The conventional
treatment fails for about 60 percent in that the patient is not
released or is hospitalized again. Conventional treatment includes
a decision about vitamin intake. Usually it is decided that the
vitamins in the food will suffice or that a multivitamin tablet
will also be given. The amounts of ascorbic acid, niacin pyridoxine,
and vitamin E may be approximately the daily allowances recommended
by the Food and Nutrition Board of the U.S. National Academy of
Sciences-National Research Council: 60 mg. of ascorbic acid, 20
mg of niacin 2 mg. of pyridoxine, and 15 I.U. of vitamin E. Is
this amount of vitamins correct? Would many schizophrenic patients
respond to their treatment better if the decision were made that
they should receive 10 or 100 or 500 times as much of some vitamins?
What is the optimum intake for these patients? I believe there
is much evidence that the optimum intake for schizophrenic patients
is much larger than the recommended daily allowances. By the use
of orthomolecular methods in addition to the conventional treatment
of schizophrenia, the fraction of patients hospitalized for the
first time in whom the disease is controlled may be increased
from about 40 percent to about 80 percent. (19)
Ascorbic Acid
It was reported by Horwitt in 1942 (20) and by later investigators
that schizophrenic patients receiving the usual dietary amounts
of ascorbic acid had lower concentrations of ascorbic acid in
the blood than people in good health. The loading-test results
of VanderKamp (8), Herjanic and Moss-Herjanic (9), and Pauling
and associates (10) have been mentioned above. In his discussion
of ascorbic acid and schizophrenia Herjanic (21) concluded:
The individual variation of the need for ascorbic acid may turn
out to be one of the contributing factors in the development of
the illness. Ascorbic acid is an important substance necessary
for optimum functioning of many organs. If we desire, in the treatment
of mental illness, to provide the "optimum molecular environment,"
especially the optimum concentration of substances normally present
in the human body (Pauling,. 1968 (1)), ascorbic acid should certainly
be included (2).
There is, moreover, a special reason for an increased intake of
ascorbic acid by patients with schizophrenia or any other disease
for which there is only partial control. About 60 mg. of ascorbic
acid a day is enough to prevent overt manifestations of avitaminosis
C (scurvy) in most people. However, there are several significant
arguments to support the thesis that the optimum intake for most
people is 10 to 100 times more than 60 mg. These arguments are
summarized in the papers and books of Irwin Stone (22) and myself
(23,24). They constitute the theoretical basis for the customary
use of about 4 gin. of ascorbic acid a day in the orthomolecular
therapeutic and prophylactic treatment of schizophrenia. A significant
controlled trial of ascorbic acid in chronic psychiatric patients
was reported in 1963 by Milner (25). The study, which was double-blind,
was made with 40 chronic male patients: 34 had schizophrenia,
4 had manic-depressive psychosis, and 2 had general paresis. Twenty
of the patients, selected at random, received 1 gm. of ascorbic
acid a day for three weeks; the rest received a placebo. The patients
were checked with the Minnesota Multiphasic Personality Inventory
(MMPI) and the Wittenborn Psychiatric Rating Scales (WPRS) before
and after the trial. Milner concluded that "statistically significant
improvement in the depressive, manic, and paranoid symptoms-complexes,
together with an improvement in overall personality functioning,
was obtained following saturation with ascorbic acid" (25). He
suggested that chronic psychiatric patients would benefit from
the administration of ascorbic acid.
We found (10) that of 106 of the schizophrenic patients we studied
who had recently been hospitalized in a private hospital, a county-university
hospital, or a state hospital, 81 (76 percent) were deficient
in ascorbic acid, as shown by the six-hour excretion of less than
17 percent of an orally administered close. Only 27 of 89 control
subjects (30 percent) showed this deficiency. Great deficiency
(less than 4 percent excreted) was shown by 24 (22 percent) of
the schizophrenic subjects and by only 1 (1 percent) of the controls.
I have no doubt that many schizophrenic patients would benefit
from an increased intake of ascorbic acid. My estimate is that
4 gm. of ascorbic acid a day, in addition to the conventional
treatment, would increase the fraction of acute schizophrenics
in whom the disease is permanently controlled by about 25 percent,
Except for that of Milner (25), no controlled trial of ascorbic
acid in relation to schizophrenia has been made, so far as I know.
Niacin and Niacinamide
The requirement of niacin (nicotinic acid) for proper functioning
of the brain is well known. The psychosis of pellagra, as well
as the other manifestations of this deficiency disease, is prevented
by the intake of a small amount of niacin, about 20 mg. a day.
In 1939 Cleckley, Sydenstricker, and Geeslin (5) reported the
successful treatment of 19 patients with severe psychiatric symptoms
with niacin and in 1941 Sydenstricker and Cleckley (6) reported
similarly successful treatment of 29 patients with niacin. In
both studies, moderately large doses of niacin, 0.3 to 1.5 gm.
a day, were given. None of the patients in these studies had physical
symptoms of pellagra or any other avitammosis. A decade later,
Hoffer and Osmond (2,3) initiated two doubleblind studies of niacin
or niacinamide in the treatment of schizophrenia. Another double-blind
study was reported by Denson in 1962 (26). In 1964 Hoffer and
Osmond (4) reported that a 10-year follow-up evaluation of the
patients in their initial studies showed that 75 percent had not
required hospitalization, compared with 36 percent of the comparison
group, who had not received niacin. Similar estimates have been
made by Hawkins (18). There are, however, contradictory statements
by other investigators. The question of the weight of the evidence
is discussed below in the section on the APA task force report.
Pyridoxine
Pyridoxine, vitamin B6 is used in the treatment of schizophrenia
in amounts of 200 to 800 mg. a day by many orthomolecular psychiatrists,
Derivatives of this vitamin are known to be the coenzymes for
over 50 enzymes, and the chance of a genotype with need for a
large intake of the vitamin is accordingly great. There is evidence
that pyridoxine is involved in tryptophan-niacin metabolism.
A double-blind placebo-controlled study has been made of pyridoxine
and niacin by Ananth, Ban, and Lehmann (27). Their experimental
population consisted of 30 schizophrenic patients: 15 were men,
15 were women, their mean age was 41.7 years, and their mean duration
of hospitalization was 10.9 years. They were randomly assigned
to three treatment groups: 1) the combined treatment group, which
received 3 gm. of nicotinic acid a day for 48 weeks and 75 mg.
of pyridoxine a day during three 4-week periods; 2) the nicotinic
acid group, which received 3 gm. of nicotinic acid a day for 48
weeks and a pyridoxine placebo; and 3) the pyridoxine group, which
received 75 mg- of pyridoxine a day during three 4 week periods
and a nicotinic acid placebo. In addition, neuroleptic preparations
were administered according to clinical requirements for the control
of psychopathology. The investigators reported that "of the ten
patients in each treatment group, seven improved and three deteriorated
in the nicotinic acid group, nine improved and one deteriorated
in both the combined treatment group and in the pyridoxine group"
(27). They also stated:
Of the three indices of therapeutic effects, global improvement
in psychopathology (Brief Psychiatric Rating Scale and Nurses
Observation Scale for Inpatient -Evaluation) scores was seen in
all three groups: the number of days of hospitalization during
the period of the clinical study was lower in both the nicotinic
acid and the combined treatment group; and only in the combined
treatment group was the daffy average dosage of phenothiazine
medication decreased. Thus, improvement in all three indices was
noted in the combined treatment group. However, several side effects
were observed during the therapeutic trials, indicating that the
vitamins used are not completely safe (27).
The investigators reached the conclusion that "on balance, these
results suggest that the addition of pyridoxine may potentiate
the action of nicotinic acid. Thus pyridoxine seems to be a useful
adjunct to nicotinic acid therapy" (27). Hawkins (18) commented
on this work in the following way:
The therapeutic effect was demonstrable even though the patients
had been hospitalized for an average of 10.9 years, were not on
hypoglycemic diets, and the doses of both pyridoxine (75 mg. daily)
and vitamin B3 (3 gm. a day) were considerably below the dosages
we routinely prescribe (18).
Cyanocobalamin
A deficiency in cyanocobalamin (vitamin B12), whatever its cause,
leads to mental illness as well as to such physical manifestations
as anemia. The anemia can be controlled by a large intake of folic
acid, but the mental illness and neurological damage cannot. A
pathologically low concentration of cyanocobalamin in the blood
serum has been reported to occur in a much larger percentage of
patients with mental illness than in the general population. Edwin
and associates (28) determined the amount of vitamin B12 in the
serum of every patient over 30 years old admitted to a mental
hospital in Norway during a period of one year. Of the 396 patients,
61 (15-4 percent) had a subnormal or pathologically low concentration
of vitamin B 12, less than 150 pg. per ml. (the normal range is
150 to 1,300 pg. per ml.). This incidence is 30 times as great
as that estimated for the population as a whole. Other investigators
have reported similar results and have suggested that a low serum
concentration of vitamin B12, whatever its origin, may cause mental
illness. In addition, of course, mental illness may accompany
some genetic diseases, such as methylmalonic aciduria, which can
be controlled only by achieving a serum concentration of cyanocobalamin
far greater than normal.
Minerals and Other Vitamins
There is some evidence that mental illness may result from deprivation
of or abnormal need for minerals and other vitamins. (See, for
example, Pfeiffer, Iliev, and Goldstein (29)). Further work in
this field by psychiatrists and biochemists is needed.
The APA Task Force Report
In July 1973 an APA task force of five physicians and one consultant
issued a 54-page report titled Megavitamin and Orthomolecular
Therapy in Psychiatry (30). In this report the Task Force on Vitamin
Therapy in Psychiatry purports to present both theoretical and
empirical reasons for completely rejecting the basic concept of
orthomolecular psychiatry, which is the achievement and preservation
of good mental health by the provision of the optimum molecular
environment for the mind, especially the optimum concentrations
of substances normally present in the human body.
Some Errors in the Report
It is mentioned in the report that in the treatment program of
the orthomolecular psychiatrists "each patient may receive as
many as six vitamins in large doses individually determined by
the treating physician as well as other psychotropic drugs and
hormones whose doses are also individually determined for each
patient" (p. 46). The assumption is made by the task force that
the optimum intake of vitamins for mental health is the conventional
average daily nutritional requirement, with growth and development
as the criteria: "In schizophrenia there is apparently an adequate
vitamin intake for growth and development until the illness becomes
manifest in the teens or early adult life" (p. 40). Mention is
made in the report of the well-known genetic diseases with both
psychic and somatic manifestations that can be controlled by an
intake of a vitamin 100 or 1,000 times the usually recommended
daily allowance, but the possibility that less obvious genetic
differences could result in an increased individual need for a
larger intake of vitamins in order to achieve good mental health,
as discussed in my 1968 publication (1) and in the earlier sections
of this paper, is rejected on the basis of arguments that have
little value or pertinence. One such argument is the following:
The two theoretical bases adduced by megavitamin proponents for
the effectiveness of NA therapy (nicotinic acid as a methyl acceptor
and NAD deficiency) are in fact generally incompatible, because
NAA [nicotinamide], when functioning as a vitamin, is bound to
the remainder of the coenzyme molecule by the nitrogen of its
pyridine ring and hence can no longer accept methyl groups. Essentially,
then, the two views of NA as a vitamin precursor of NAD and as
a methyl acceptor are incompatible, except for the possibility
that there is in schizophrenia double deficit - both a vitamin
deficiency and a transmethylation defect and that nicotinic acid
has the happy fortune to serve two purposes simultaneously (pp.
40-42).
There is an obvious error in this task force argument. There is
no incompatibility between two functions of nicotinic acid; some
molecules may engage in one function and others in the other.
A defect in either function might be controlled by increasing
the intake of the vital substance. A "double deficit" is not needed.
The authors of the report would have wen the fallacy in their
argument if they had set up some equilibrium and reaction rate
equations, as was done in my 1968 paper (1). The task force expresses
an interesting misunderstanding of the nature of vitamins, in
the following words: "By common definition a vitamin is not only
an essential nutrient, but it is essential because it is transformed
into a coenzyme vital for metabolic reactions" (p. 41). In fact,
this is not the common definition of a vitamin; it is wrong. Some
vitamins, including vitamin C, are not known to be transformed
into a coenzyme. This misunderstanding by the task force may have
contributed to the misinterpretation of the evidence for and the
theoretical basis of orthomolecular psychiatry.
Nicotinic acid as a methyl acceptor is referred to in the report:
"From Study No. 12: nicotinic acid in the dosage of 3000 mg. per
day can neither prevent nor counteract the psychopathology induced
by the combined administration of a monoamine oxidase inhibitor
(tranylcypromine) and methionine" (p. 16). In fact, the molecular
weights of nicotinic acid and methionine (a methyl donor) are
nearly the same, 123 and 149, respectively. Instead of 3 gm.,
16.5 gm. of nicotinic acid would have had to be given each day
to accept the methyl groups donated by the 20 gm. of methionine
that was given each day. The study referred to as number 12 (31),
which resulted in an exacerbation of the illness of 30 schizophrenic
patients who participated in it, has no value as a test of the
methyl acceptor theory of nicotinic acid. Consideration of ethical
principles may have kept the investigators from repeating the
study with use of the proper equimolar amounts of nicotinic acid
and methionine.
The Failure To Discuss Ascorbic Acid and Pyridoxine
In several places the APA task force report mentions the use of
1 to 30 gm. of ascorbic acid a day by orthomolecular psychiatrists.
There are, however, no references to the literature. Milner's
double-blind study (25) is not mentioned, nor is there any discussion
of the many papers in which a low level of ascorbic acid in the
blood of schizophrenics was reported. Neither the general theory
of orthomolecular psychiatry, as presented in my 1968 paper (1)
nor any of the special arguments about the value of ascorbic acid
is presented or discussed in any significant way. There is, moreover,
no discussion in the report of pyridoxine and no reference to
the 1973 work by Ananth, Ban, and Lehmann (27) on the potentiation
by pyridoxine of the effectiveness of niacin in controlling chronic
schizophrenia. The title of the report, Megavitamin and Orthomolecular
Therapy in Psychiatry, is completely inappropriate, and the general
condemnation of megavitamin and orthomolecular therapy is unjustified.
Niacin
The report does my that it is possible that the other watersoluble
vitamins will prove to be more effective than niacin but it adds;
Nonetheless, the massive use of niacin has always been the cornerstone
of the theory and practice of megavitamin advocates. Since this
has proved to have no value when is it employed as the sole variable
along with conventional treatments of schizophrenia, the burden
of proof for the complex and highly individualized programs now
advocated would appear to be on the proponents of such treatment
(p. 46).
I shall point out below that the principles of medical ethics
prevent orthomolecular psychiatrists from withholding from half
of their patients a treatment that they consider to be valuable.
Controlled tests can be carried out only by skeptics. I now ask
whether the task force is justified in saying that the massive
use of niacin has been proved to have no value when it is employed
as the sole variable along with conventional treatments of schizophrenia.
My answer to this question, from a study of the evidence quoted
in the report, is that it is not justified. The evidence that
niacin has no value is far from conclusive. A beneficial effect
of niacin or niacinamide was reported for three double-blind studies
(two by Hoffer and Osmond and their collaborators (2,3,32) and
one by Denson (26)) and in 12 open clinical trials by other investigators
referred to in the report. On the other hand, the report mentions
7 doubleblind studies in which a statistically significant difference
between the niacinamide subjects and the controls was not observed.
A failure to reject with statistical significance the nun hypothesis
that the treatment and the placebo have equal value is not proof
that the treatment has no value. The explicit statistical analysis
of an alternative hypothesis should be carried out: for example,
the hypothesis that there is a 10-percent or 20-percent greater
improvement in the treated subjects than in the placebo subjects.
No such analysis has been published.
In fact, some of the "negative" studies indicate that the treatment
has value. The report states that "Greenbaum (33) reported a double-blind
study of 57 schizophrenic children who received nicotinamide 1
gm. per 50 lbs of body weight or placebo for six months. No statistically
significant differences were seen in the two groups as a result
of the treatment" (P. 11). it is true that no statistically significant
differences were wen, but that is not the whole truth, The principal
criterion of improvement in this study was the increase in the
score on a clinical scale of observable behavior categories. The
average improvement in the score of the 17 children receiving
niacinamide was 4.0 units and that of the 24 controls was 2.6
units (there was a third group of 16 children who were given a
tranquilizer and niacinamide). The children who were given niacinamide
showed a 54-percent greater improvement than the children who
were given placebo. The groups were too small, however, for the
difference to be significant at the 95-percent level of confidence.
This study does not prove that niacinamide has no value. Rather,
it indicates that niacinamide has greater value than the placebo,
even though it fails to show this at the customary level of statistical
significance.
The Hoffer-Osmond Diagnostic Test
Two-thirds of the report relates to niacin and one-third to the
Hoffer-Osmond Diagnostic Test (HOD) (34), which has no special
connection with megavitamin or orthomolecular psychiatry except
that it was devised by the originators of niacin therapy. The
report should have been given the- title Niacin Therapy and the
HOD Test, or published as two reports, one on niacin and one on
the HOD test. It would have been still better for the task force
to have discussed megavitamin and orthomolecular therapy in psychiatry
fully.
The Question of Controlled Experiments
The report refers to the low credibility of the megavitamin proponents,
whose published results were not duplicated in studies carried
out by one of the task force members (p. 48). The penultimate
sentence of the report is, "Their credibility is further diminished
by the consistent refusal over the past decade to perform controlled
experiments and to report their new results in a scientifically
acceptable fashion" (p. 48).
I have talked with the leading orthomolecular psychiatrists and
have found that they feel the principles of medical ethics prevent
them from carrying out controlled clinical tests, with half of
their patients receiving orthomolecular therapy in addition to
the conventional treatment and the other half receiving only the
conventional treatment. It is the duty of the physician to give
to every one of his patients the treatment that in his best judgment
will be of the greatest value, Some psychiatrists, including Hoffer
and Osmond, carried out controlled trials 20 years ago. They became
convinced that orthomolecular therapy, along with conventional
treatment, was beneficial to almost every patient. From that time
on their ethical principles have required that they give this
treatment and not withhold it from half of their patients. The
task force is wrong in criticizing the orthomolecular psychiatrists
for not having carried out controlled clinical trials during the
last few years. Instead, it is the critics, who doubt the value
of orthomolecular methods, who are at fault in not having carried
out well-designed clinical tests.
It is also the duty of a physician to give to a patient a treatment
that may benefit him and is known not to be harmful. The incidences
of toxicity and other serious side effects of the doses of vitamins
used in orthomolecular medicine are low. There is significant
evidence that an increased intake of certain vitamins may benefit
the patient. It is accordingly the duty of the psychiatrist to
prescribe these vitamins for him.
The Bias of the Task Force
The last sentence of the report reads as follows:
Under these circumstances this Task Force considers the massive
publicity which they promulgate via radio, the lay press and popular
books, using catch phrases which are really misnomers like "megavitamin
therapy" and "orthomolecular treatment," to be deplorable (p.
48).
This sentence, like others in the report, shows the presumably
unconscious bias of the task force. "Promulgate" (misused here)
is a pejorative word, and "catch phrases" is a pejorative expression.
I do not understand why megavitamin therapy and orthomolecular
treatment should be called misnomers. This concluding sentence,
like many others in the book, seems to me to have been written
in order to exert an unjustifiably unfavorable influence on the
readers of the report.
I have written two popular books, No More War! (35) and Vitamin
C and the Common Cold (24). I feel that each of them was worthwhile
and that neither would have been easily replaced by a more technical
book. The second book (24) was written because I had discovered
in reading the medical literature that there was much evidence
there about the value of ascorbic acid in decreasing both the
incidence and the severity of the common cold and that this evidence
had been suppressed or misrepresented by the medical and nutritional
authorities. Since publication of the book, eight new studies
have been reported. Every one of these has verified the value
of ascorbic acid. The APA report shows the same sort of negative
attitude as that shown by the authorities toward ascorbic acid
in relation to the common cold. There seems to be a sort of professional
inertia that hinders progress.
Conclusions
Orthomolecular psychiatry is the achievement and preservation
of good mental health by the provision of the optimum molecular
environment for the mind, especially the optimum concentrations
of substances normally present in the human body, such as the
vitamins. There is evidence that an increased intake of some vitamins,
including ascorbic acid, niacin pyridoxine, and cyanocobalamin,
is useful in treating schizophrenia, and this treatment has a
sound theoretical basis. The APA task force report Megavitamin
and Orthomolecular Therapy in Psychiatry discusses vitamins in
a very limited way (niacin only) and deals with only one or two
aspects of the theory. Its arguments are in part faulty and its
conclusions are unjustified.
