Pharmacologic Use of Niacin
Abstract
Niacin is required for a host of critical redox and adenosine diphosphate-ribosylation reactions in metabolism. Niacin deficiency leads to the distinctive signs and symptoms of pellagra, but these can happen in an unpredictable progression and can be altered in patients with polymorphisms in any of the hundreds of niacin-dependent enzymes. The symptomatology of niacin deficiency is becoming a forgotten knowledge base, and niacin deficiency is likely underdiagnosed. Additionally, high levels of niacin and niacinamide have pharmacological effects distinct from their role as sources of vitamin B3, allowing a wide range of effects on processes such as blood flow and lipid metabolism, which can be used to treat or prevent a variety of disease processes.

Niacinamide’s Potent role in Alleviating Anxiety with its Benzodiazepine-like Properties: A Case Report
Abstract
Anxiety disorders are extremely debilitating
and are the most common psychiatric disorders
in the United States. Such patients have
greater chances of developing other medical
illnesses such as chronic obstructive pulmonary
disease, diabetes and hypertension. The
underlying anxiety that exists in these patients
also tends to prolong the course of any additional
medical illnesses that they may develop.
The conventional approach to severe anxiety
involves pharmacotherapy with benzodiazepines,
selective serotonin re-uptake inhibitors
(SSRIs), or other medications such as
buspirone, imipramine or trazodone. A case
report demonstrated that the use of 2500mg
of niacinamide (nicotinamide) per day ameliorated
severe anxiety in a 34-year-old male
patient. It appears that niacinamide has
therapeutic properties similar to the
benzodiazepines. However, the therapeutic effects
of niacinamide likely have little to do with
it acting as a ligand for the benzodiazepine
receptor. Niacinamide might exert its effects
through its modulation of neuro-transmitters
that are commonly unbalanced in those areas
of the brain associated with anxiety. Niacinamide
might also reduce anxiety by shunting
more tryptophan toward the production
of serotonin and/or by simply correcting a vitamin
B3 dependency. The use of niacinamide
for extended periods of time appears to be safe,
but megadoses can cause sedation, nausea
and vomiting. More case reports, research and
rigorous controlled trials are needed to properly
evaluate niacinamide’s therapeutic effectiveness,
safety and mechanisms of action for
the treatment of anxiety.

Sedation, Relaxation, and Regulation: The Clinical Application of Gammaaminobutyric acid, Niacin, and Melatonin for the Treatment of Insomnia
Abstract Insomnia is a common problem seen in clinical practice. It has been defined as unsatisfactory
sleep that impacts daily functioning, and for diagnostic purposes can be separated into acute
insomnia (i.e., less than 30 days), or chronic insomnia (i.e., greater than or equal to 30 days). The
majority of insomnia cases are associated with other medical conditions, giving rise to a more appropriate
diagnosis of “comorbid insomnia.” The work-up of chronic insomnia is described. Improving
sleep habits should be the foundation of a program designed to correct insomnia, especially if it
is considered chronic. The author has been experimenting clinically with a variety of orthomolecular
substances for over 15 years, and has found a specific combination of three orthomolecules to be particularly
effective for many cases of acute or chronic insomnia. This approach is called, “SRR,” which
refers to the use of gamma-aminobutyric acid, niacin, and prolonged-release melatonin to promote
sedation, relaxation, and regulation, respectively. A brief description of each of these orthomolecules is
included, as well as appropriate prescribing information. Other clinical considerations are described
to assist clinicians in managing insomnia.

An N-of-1 Placebo-Controlled Trial in Clinical Practice: Testing the Effectiveness of Oral Niacinamide (Nicotinamide) for the Treatment of Anxiety
Abstract Background: Many patients with anxiety often turn to complementary and alternative
medical (CAM) treatments. Because of the popularity of CAM among patients with anxiety, it
is important that emerging CAM treatments are researched for safety and efficacy. One emerging
CAM treatment that shows potential as an anxiolytic agent is the amide form of vitamin B-3, also
known as niacinamide (nicotinamide).
Objectives: To evaluate the efficacy and safety of niacinamide in a participant with anxiety symptoms.
Design: Double-blind, placebo-controlled N-of-1 trial of niacinamide versus placebo for the treatment
of anxiety symptoms.
Setting: The Robert Schad Naturopathic Clinic, the outpatient clinic of the Canadian College of Naturopathic
Medicine (North York, Ontario).
Intervention: Following a 2-week washout cycle, the 26-year-old female participant was allocated to
a 4-week treatment Period (Block) where she was provided with 3000 mg/day of niacinamide, or an
equivalent-looking placebo, at 2-week intervals. Following another 2-week washout cycle, the same
procedure was followed.
Main outcome measures: Beck Anxiety Inventory (BAI) questionnaire, Measure Yourself Medical
Outcome Profile (MYMOP) questionnaire, 14-day medication diary for side effects and pill counts,
and laboratory testing to monitor safety and possible toxicity.
Results: The BAI results did not demonstrate a statistically significant difference in favour of
the niacinamide for Periods 1 and 2 (p=0.07). There were no statistically significant differences
in favour of the niacinamide for all the dimensions of the MYMOP, which include Symptoms 1
(p=0.30) and 2 (p=0.40), Activity (p=0.13), and Wellbeing (p=0.09) over the duration of the
study. The baseline and end-of-trial evaluations (i.e., physical examination and laboratory testing)
were within normal limits. None of the participant’s transaminase levels were abnormal
during the trial.
Conclusions: Niacinamide is safe at dosages as high as 3000 mg/day. Treatment with niacinamide
produced no favourable therapeutic effects upon the participant’s symptoms of anxiety and anxiety scores
per the BAI and MYMOP questionnaires.

Clinical Experiences with a Vitamin B3 Dependent Family
Abstract
A vitamin dependency occurs when there
is a defect in the binding of the vitamin-related
coenzyme to its apoenzyme. The only way to
correct a vitamin dependency is to obtain
daily amounts much greater than recommended
dietary allowances. I believe that the
most common vitamin dependency among
patients with mental illnesses is vitamin B3.
These three cases involve members of the
same family. Each case improved clinically
upon taking megadoses (500-1500mg/day)
of the vitamin. A fourth member of this family
has schizophrenia. This is significant
since recent postmortem biopsies of brain
tissues have shown defects in the ability of
schizophrenic patients to generate adequate
amounts of vitamin B3 coenzymes from
tryptophan. Families share similar genetics
and environmental factors, and thus
this family likely shares varying degrees of
the ability to synthesize adequate amounts
of vitamin B3 coenzymes. If schizophrenic
genes are common among the entire human
population, then the majority of people will
suffer from slight-to-severe defects in this
biosynthetic pathway.

The Treatment of Alcoholism with Vitamin B3
Abstract The consequences of excessive and prolonged use of alcohol leads to mild-to-severe forms of
pellagra (i.e., some combination of diarrhea, dermatitis, dementia, and possibly death). The author
describes the work of many notable individuals who reported on the clinical effectiveness of vitamin
B3 treatment for compulsive drinking behaviour, alcohol withdrawal delirium, and for improving
sobriety. There is definitely a significant therapeutic role that vitamin B3 could play (mostly, niacin)
if it was part of the mainstream approach to treating alcoholism and its related complications.

Vitamin B3 for Depression: Case Report and Review of the Literature
Abstract While on parental leave during November 2009, my clinical shift was spearheaded by
one of my colleagues who recommended fairly significant doses of inositol hexaniacinate to treat a
patient’s depression. In January 2010, the patient returned for a visit on my clinical shift, and much
to my surprise her long-standing depression had resolved. As a result, I conducted a search for articles
describing the use of vitamin B3 for depression. Six articles were found to meet the inclusion criteria
and were included in this review. There is evidence that niacin and niacinamide (in combination
with tryptophan) might be effective for the treatment of depression. Hypothetical reasons for niacin’s
effectiveness include its vasodilatory properties, while the mechanisms responsible for the effectiveness
of niacinamide involve its ability to inhibit tryptophan pyrrolase and possibly protect neurons
from damage. The side effect profiles of niacin and the niacinamide-tryptophan combination are
also discussed. Even though the mechanisms of action for niacin and niacinamide have not been
substantiated from well conducted controlled clinical trials, these forms of vitamin B3 appear to have
beneficial effects upon depression. It is imperative that properly designed controlled trials are developed
in order to determine the true therapeutic effects and adverse effect profile of both preparations
of vitamin B3 for depression.

Treating Dementia with Vitamin B3 and NADH
Abstract Dementia affects approximately 5 million people in the United States, and about 475,000
elderly Canadians. Dementia is a debilitating and often progressive illness. The most common type
of dementia is Alzheimer’s disease, followed by vascular types. There is a need to investigate novel
treatments because the current crop of medications have limited value. Niacin might be a worthwhile
treatment to consider. Research has shown that the risks of incident AD increase when patients have
insufficient intakes of niacin from diet or medical conditions that precipitate niacin deficiency. Clinical
reports have documented therapeutic benefits when patients receive optimum daily doses of niacin.
Preliminary trials evaluating the reduced form of nicotinamide adenine dinucleotide (NADH) found
it a safe and effective treatment for AD. At present, research evaluating the therapeutic applications of
niacin and/or NADH for dementia is at a standstill. However, niacinamide is being evaluated in a
clinical trial to determine if it is safe and beneficial for patients with AD. Hopefully, the forthcoming
results will encourage researchers and clinicians to study niacinamide further, and revisit the therapeutic
potential of vitamin B3 as a safe and an effective treatment for dementia.

Tapering Off Psychotropic Drugs: Using Patient Cases to Understand Reasons for Success and Failure
Abstract Over the past several years the author has helped a number of patients taper off psychotropic
drugs (PDs). This emerging aspect of his clinical work arose when patients demanded such services.
During the tapering process, a combination of orthomolecular and/or botanical medicinal extracts
can assist patients by minimizing withdrawal reactions and mental instability. Fourteen cases are
described. The results showed that eight patients were able to remain functionally well following PD
discontinuation, whereas the remaining six cases were not. Reasons for these different outcomes are
discussed, and include: (1) problems in overcoming pharmacological dependence; (2) being psychologically
dependent on being psychiatrically labeled; (3) not having a sufficient life strategy; and (4)
being potentially brain-damaged from PDs. This paper can assist and empower clinicians to better
understand some of the reasons why patients remain functionally well following tapering while
other patients do not.

Pandeficiency Disease, by A. Hoffer, Ph.D., M.D.
Introduction
Diagnosis classifies disease for two
main reasons: (1) to improve prognosis
and (2) to improve treatment. Prognosis is
very important so patients and family can
prepare for the future especially if the future
is very dim. Estimating when a person
will die may be extremely important for
all sorts of reasons. Before specific treatment
was discovered doctors were judged
on their ability to prognose correctly. It
would be very bad for the physicians reputation
if his prognosis were wrong. Many
years ago when I started to practice some
of my patients, when giving me their history,
would tell me that their doctor had
told them they would die but the doctor
died before they did. Good doctors were
good prognosticators and this depended
upon accurate diagnosis.
Diagnosis became even more important
when specific treatment was discovered.
Diagnosis advised the clinician what
treatment to use. It was assumed that
patients with the same diagnosis would
respond to similar treatment which had
already been described by other doctors.
I had pneumonia in my early teens. Our
friendly family doctor (he was also surgeon.
emergency doctor, obstetrician, etc.
as he was the only one in the community )
told mother I had pneumonia and ordered
mustard plasters. It must have been very
effective or else my pneumonia was very
mild as I was well in a couple of days.
That was standard treatment for a disease
that killed a large proportion of the
victims. This diagnosis was a descriptive
diagnosis. By listening to my chest the
doctor discovered something wrong and
it was most likely pneumonia. No other
diagnostic tests were available.
After it was discovered that many
lung lesions were possible it became necessary
to distinguish one from another.
Was it bacterial and if so which bacteria,
staph. or strep.? Was it cancer or silica
or tuberculosis? Specific laboratory tests
are used. Diagnosis is now etiologic. It
is based on the cause of the condition.
Until the causal diagnosis is made the
treatment can not be very successful. This
is the pathway diagnosis has traveled,
from description of the site, the organ,
and later to the cause when known. If
the cause remains unknown the diagnosis
remains descriptive. Psychiatric diagnosis
is almost entirely descriptive.

Supplemental Niacinamide Mitigates Anxiety Symptoms: Three Case Reports
Abstract
The purpose of this report is to highlight
the potential of niacinamide for the
treatment of anxiety disorders. Three patients
were prescribed large pharmacological
doses of niacinamide (2,000-2,500 mg
per day). Each of the patients had considerable
relief from their anxiety when regularly
using niacinamide. The possible biochemical
reasons for niacinamide’s effectiveness
might be related to the correction
of subclinical pellagra, the correction of an
underlying vitamin B3 dependency disorder,
its benzodiazepine-like effects, its ability to
raise serotonin levels, or its ability to modify
the metabolism of blood lactate (lactic
acid). Adverse effects did not occur with
these doses, but nausea and vomiting can
occur when doses as high as 6,000 mg per
day are used. These positive case reports
suggest that niacinamide might be helpful
for the treatment of anxiety disorders. However,
definitive proof requires properly conducted
randomized controlled trials to assess
niacinamide’s actual therapeutic effects
and adverse effects profile.
