Do Vitamins or Minerals (Apart From Lithium) Have Mood-Stabilizing Effects?

Nutritional scientists have been well funded by agribusiness to find ways to deal with factors that
interfere with animal health, including aggressive and destructive behavior. When farm animals
become "violent"-when pigs start biting each others' ears and tails, when chickens attack
chickens-farmers have learned that the aggressive behavior can be reduced by adding certain
minerals and vitamins to their diet, without the need for veterinary intervention.

In 1996, animal nutrition specialist David L. Hardy described this approach to Anthony F. Stephan,
whose children had severe treatment-resistant bipolar disorder. Stephan then added similar
nutrients to his children's diet. On the nutritional supplements, both children stabilized clinically and
have not needed psychiatric medication for the last 5 years. Hardy and Stephan began advising
family members and friends about this nutrient supplement and have now worked with over 2500
psychiatric patients (D. L. Hardy, personal communication, 2001). They also began to collaborate
with Bonnie J. Kaplan, Ph.D., a research psychologist at the University of Calgary in Alberta, Canada.

In this issue, Kaplan and colleagues (1) describe an open trial of the first 14 adults with bipolar
disorder treated with this nutritional supplement, which consists of a broad range of minerals and
vitamins, plus 3 amino acids and several antioxidants. Symptom reductions were clinically noted
within 2 weeks and sustained over 6 months of observation. All outcome measures showed significant
improvements (55% to 66% symptom reduction), and a strong effect size (> .80) was observed for
ratings of depression as well as mania. Most patients could reduce their doses of psychiatric
medications, and some patients became stable without any psychiatric medication. Only 2 patients
started on new medications that might conceivably have contributed to their stabilization. Even
allowing for the usual overestimation of effects in open-label series, these preliminary findings raise
interesting
questions about nutrition-behavior interactions.

In view of the 50 years of experience with lithium, the notion that minerals can treat bipolar disorder is
unsurprising. However, the nutrient supplement studied by Kaplan and colleagues contains no lithium.
Might other dietary nutrients have mood-stabilizer properties?

Some may object that a clinical trial of a mixture of ingredients is inherently unscientific: How can one
know which ingredient is the active one, whether a smaller number of ingredients will have the same
clinical effect, or whether the same ingredients are active in different patients? These questions will
become worth pursuing once it has been formally determined whether the mixture, handed down
from animal husbandry as a single entity, works in humans. Kaplan's open-label report justifies her
now ongoing controlled study, whose outcome appropriately precedes pursuing questions of
mechanism of action (2) and parsimony.

Even so, it is difficult to avoid speculating about possible mechanisms. Might minerals serve as
catalysts for enzymes involved in neurotransmitter
metabolism, change drug biotransformation, modify membrane receptors or channels, influence
second or third messenger systems, or alter gene expression? Lithium, a single cation, has spawned a
minor industry of investigations into mechanisms of action, and the possibilities if there were
numerous interacting micronutrients (the collective term for minerals and vitamins) are staggering.

My interest in this nutrient mixture was initially sparked by a case in my clinical practice. A 10-year-old
with bipolar disorder was referred for
treatment of severe temper tantrums, which had lasted for 2 to 4 hours daily for 4 months. The
well-nourished child had no prior psychiatric history or treatment. After 2 days on the Hardy-Stephan
nutrient regimen, his tantrums showed significant improvement, with the father-psychiatrist reporting a
"complete" absence of outbursts or even irritability at 5 days. After 2 weeks, the available supply of
the nutrient supplement was exhausted, and tantrums returned within 48 hours. A similar supplement,
containing most of the same ingredients, was then started and produced a moderate improvement,
which parents and teachers estimated as 60% of the original effect. When restarted on the original
formula, the symptoms were judged to have again responded completely. This naturalistic
A-B-A-C-B trial caught my attention because of the full stabilization without psychiatric medications
and the absence of observed adverse effects.

I proceeded to cautiously conduct additional trials of the Hardy-Stephan nutrient supplement.
Among 22 patients (10 adults, 9 adolescents, 3 preadolescents) who clinically met criteria for bipolar
disorder, 19 showed what I judged to be a positive response (2 mild, 7 moderate, 10 marked
improvement). Among the 15 patients who were being treated with medications when they began
the nutritional supplement, 11 patients have been stable for 6 to 9 months without psychiatric
medications. These observations are consistent with Kaplan's open-label findings, but leave
questions of safety unresolved.

Nausea was the main adverse effect in Kaplan's study. In the larger anecdotal experience of Hardy
and Stephan and my limited clinical observations, loose stools and headache were common.
Diarrhea,
vomiting, flatulence, and agitation were less common. Classical symptoms of mineral or vitamin
toxicity were not encountered, but might have
emerged with lengthier treatment or more systematic observation.

The Hardy-Stephan supplement contains many nutrients at high doses relative to the
Recommended Daily Allowance (RDA), but these RDA levels were primarily established to prevent
deficiency disorders in the general population. A broader range of vitamin and mineral functions
(3,4) are considered in formulating the newer daily intake standards, which vary widely because of
different criteria for adequacy and different health goals. (5) Although most ingredients in the nutrient
supplement studied by Kaplan and colleagues appear well within safe limits, any multi - ingredient
treatment might have toxic effects that cannot be readily predicted from its individual components.
Even though it contains only "natural" ingredients and is not under U.S. Food and Drug Administration
(FDA) purview, the
Hardy-Stephan nutrient supplement should be examined in controlled empirical research - just as
new pharmacologic agents are - to properly
assess adverse effects and potential risks.

Psychiatrists do not normally think of vitamins or minerals as modifiers of the effects of psychiatric
medications, but the early anecdotal experience with this nutrient supplement suggests that there
may be strong micronutrient-medication interactions. This mineral-vitamin supplement
seems to generally potentiate the clinical properties of psychiatric drugs. Most patients in the
Kaplan et al. study could be managed with less
medication after the nutrient supplement was added. To avoid medication toxicity, Hardy and
Stephan have suggested to patients' psychiatrists that the doses of psychiatric medications be
rapidly reduced shortly after the
nutrient supplement is initiated. In my observations, transitioning patients from medications to
micronutrients is exceedingly tricky to manage. Introducing micronutrients too quickly can increase
the adverse effects of medications, including agitation, while withdrawing psychiatric medications
too quickly can result in symptom exacerbation. Often, both increased adverse effects and symptom
resurgence are seen at once. Much more data are needed about how to "transition" patients who
are currently taking psychiatric medications. Although it appears less difficult to treat
medication-naive patients (such as my 10-year-old patient), the transition from psychiatric
medications to micronutrients can require genuine technical savvy-even for patients who have not
taken such medications for several weeks or months. Clinicians who mistakenly approach these new
findings as encouragement to combine micronutrients with psychiatric medications may find that
they have stepped into a serious quagmire.

Although health food advocates have made numerous claims without scientific documentation,
nutritional influences on mental illness have received considerable research attention, (6) some of
which is quite rigorous and promising. Andrew Stoll's research on omega-3 fatty acids for bipolar
disorder (7,8) and Eugene Arnold's work on omega-6 fatty acids forattention deficit disorder (9-11)
suggest that these nutrients might themselves be therapeutic. Other micronutrients (calcium,
chromium) and macronutrients (inositol, amino acids) have also shown some potential for influencing
mood disorders. (12-15) Arnold's recent findings suggest that relative zinc deficiency might explain
why some patients with ADHD do not show a more robust response to psychostimulants. (9)

Several large-scale double-blind placebo-controlled studies of RDA or high-dose multivitamin
regimens in adults have reported improved scores of mood and cognition (16,17) as well as anxiety
and somatic symptoms. (18) A
recent review reported that 10 of 12 randomized double-blind placebo-controlled studies found
that multi-micronutrient regimens can improve cognitive functioning in children. (19) However,
high-dose multivitamin treatments have not been found to be effective in children with ADHD or
learning disorders. (11,20)

Speculatively, there is a great deal to learn about minerals and vitamins in psychiatric
pathophysiology and psychopharmacology. It is intriguing that many of the enzymes proposed as
target sites of lithium action are metalloenzymes that are noncompetitively inhibited by lithium, which
probably acts by displacing the divalent cation. (21) Why would supplementation with divalent
cations have a therapeutic effect? Do we know enough about complex intracellular regulatory
interactions to answer this question? Individual micronutrients will need to be examined in
combination with lithium, but it is unlikely that the physiology will be so simplistic and dyadic. The
groundbreaking approach of examining several nutrient ingredients at once, while a violation of our
usual tenets of investigation, may present an opportunity to examine how micronutrients might
operate in concert.

Assessing the safety and efficacy of multinutrient formulas will require considerable research.
Developing dose-effect curves for each micronutrient, and examining all possible combinations of
micronutrients, will be a horrifically large task. (22) Many years will be required to arrive at a formula
that is optimal for the general population, but it is more likely there will eventually be different
formulas whose safety and efficacy are optimized to the metabolic requirements of treating
different disorders, different individuals, different ages, and different comorbid health situations.

The possibility of a nutritional alternative to drug treatment may raise hope and carry the risk of
igniting public interest beyond reasonable bounds. Some patients may find it difficult to wait for
nutrient supplements to be examined in humans for both efficacy and safety in controlled trials, and
clinicians will need to help patients keep their enthusiasm from pushing usage beyond its scientific
basis. Similarly, clinicians will want to think twice if they are tempted to forge ahead with empirical
trials of this novel treatment with possible unknown risks and unproven benefit. Some physicians,
presuming a low risk of toxicity, may reason that it is judicious to allow some drug-naive patients to
proceed with empirical trials of nutrient supplements for a few weeks before committing them to
treatment with psychiatric medications. Most clinicians will want the reassurance of systematic safety
data before beginning to examine its effects in patients. Clinicians will hopefully minimize risks of
nutrient-medication interactions by initially restricting their trials to patients who have not recently
used psychiatric medications.

If Kaplan and colleagues' preliminary findings are confirmed in controlled research, and if safety
studies are favorable, what then? What if some psychiatric patients could be treated with
inexpensive vitamins and minerals rather than expensive patented pharmaceuticals? or what if some
doses of psychiatric drugs could be reduced by the concurrent use of nutrients? The economic
implications, for individual patients and for the pharmaceutical industry, are difficult to overlook. For
now, micronutrient treatments and other nutritional approaches remain in a very early stage of
scientific investigation. Depending on how this line of research develops, clinicians and researchers
may need to rethink the traditional bias against nutritional supplementation as a potential treatment
for major psychiatric disorders.

Jackass. Actually, my doc wanted me to try the treatment but it costs like $200 a month or some shit which I don't have so I would rather try meds which insurance covers. You guys should read it though. It is interesting.
