Our
physical bodies are made up of water, fat, protein,
carbohydrates, and similar substances. Therefore,
it's logical to expect that if something is
wrong with out bodies, proper manipulation of
the elements of which they are made will be
a major factor in reestablishing health.
- Jonathan Wright, M.D.
Employing vitamins,
minerals and amino acids to create optimum nutritional content and
balance in the body, orthomolecular medicine targets a wide range
of conditions, including depression, hypertension, schizophrenia,
cancer and other mental and physiological disorders.
Uses
For the better
part of the 20th century, we have been taking vitamin and mineral
supplements to eliminate deficiencies. Orthomolecular medicine takes
this idea one step further, holding that larger than usual doses
of certain nutrients can actually prevent or cure disease. Although
there is still considerable debate over specific dosages and their
therapeutic effects, the basic principle is now firmly established
and widely accepted. Two of America's greatest scourges-heart disease
and high blood pressure-can both be held at bay by high-dose nutrients,
and advocates of this therapy insist that many other chronic conditions,
including diabetes and schizophrenia, can be helped as well.
Procedure
of Treatment
With certain
vitamins, it is possible to boost your intake of therapeutic levels
simply by altering your diet. For instance, you can easily get 400
micrograms of heart-healthy folic acid by increasing your consumption
of green leafy vegetables and fresh fruits. However, the only way
to get medicinal doses of many other nutrients is to take supplements.
This is true of Vitamin E. For most people, it is also true of Vitamin
B6, even though it is plentiful in whole-grain cereals and breads,
beans and nuts. Likewise, therapeutic levels of calcium are hard
to achieve without taking a supplement.
Benefits
Heart Disease:
Medical experts have long held that reducing the amount of animal
fat in the diet can reduce the risk of heart disease. Now they are
beginning to recognize that large doses of Vitamin E have a similar
protective effect. While the recommended dietary allowance for the
vitamin is only 30 international units (IU) daily, several large
surveys have linked higher doses of Vitamin E-at least 200 IU-with
lower rates of cardiovascular disease. Even better, the Cambridge
Heart Antioxidant Study (CHAOS for short) discovered that 400 to
800 IU of Vitamin E slashed the number of non-fatal heart attacks
among heart disease patients by 50 per cent in the first year of
treatment. Another nutrient with strong links to heart health is
folic acid, a member of the Vitamin B family. Scientists first began
to suspect its impact when they noticed high levels of homocysteine
in children suffering from a severe form of hardening of the arteries
that's usually found only in older adults. Homocysteine is suspected
of damaging blood vessel walls, and further investigation revealed
that kids lacked adequate amounts of an enzyme needed to clear it
from the blood. As it turns out this enzyme requires folic acid
to do its job. Additional research found that many adults also have
higher than normal levels of homocysteine in the blood, and that
they too are at greater risk of heart disease. The investigators
found that a daily dose of between 0.5 and 5 milligrams of folic
acid could bring homocysteine levels under control. But would this
alone protect them from heart disease? The question remained unanswered
until Dr. Eric Rimm and his associates at Harvard University conducted
a study of over 80,000 nurses. Rimm discovered that, as the women
increased their intake of folic acid and Vitamin B6 (another vitamin
involved in homocysteine metabolism), their risk of heart attack
declined. The risk was lowest in women who were getting more than
400 micrograms of folic acid and more than 3 milligrams of vitamin
B6 in their daily diet (more than twice the recommended dietary
allowances). The evidence was so compelling that, in an April 1988,
editorial, the prestigious New England Journal of Medicine
concluded that all Americans should take 400 micrograms of folic
acid a day. The bottom line: To maximize your chances of escaping
heart disease, many experts now recommend that you not only follow
a low-fat diet, but also supplement it with 400 IU of Vitamin E,
3 milligrams of Vitamin B6, and 400 micrograms of folic acid per
day.
High Blood Pressure: There is accumulating evidence that
an increase in mineral intake can be an effective remedy for mild
hypertension. Clinical studies have found that, for people with
a deficiency, extra calcium can lower high systolic blood
pressure readings by as much as 13 points, and reduce diastolic
readings to some extent as well. (Systolic blood pressure
is the force against the artery walls during each beat of the heart.
Diastolic readings give the pressure while the heart is at
rest.) Calcium supplements have proven especially effective for
people who are salt-sensitive-that is, those whose blood pressure
goes up when they eat too much salt. Similarly, a recent study entitled
Dietary Approaches to Stop Hypertension (DASH) linked deficiencies
in calcium, magnesium and potassium with higher blood pressure readings,
and found that merely boosting intake to recommended levels is sufficient
to lower systolic and diastolic readings by 11.4 and 5.5 points
respectively in people with high blood pressure. This modest increase
in mineral intake produces the same results as a standard high blood
pressure medication. Recommended daily allowances of the minerals
are 1,000 milligrams of calcium, 400 milligrams of magnesium, and
3,500 milligrams of potassium. When taking calcium supplements,
it is important to boost your intake of Vitamin D as well, since
without enough of this vitamin, the calcium you take will not be
absorbed into the bloodstream. For example, when older women take
calcium supplements to forestall the brittle-bone disease osteoporosis,
they are usually advised to take as much as 800 IUs of Vitamin D
daily-twice the standard recommendation.
Schizophrenia: This calamitous and still unexplained mental
disorder sparked the first experiments with high-dose nutrient therapy.
Indeed, when Linus Pauling, Ph.D., coined the word 'orthomolecular',
he was referring to the schizophrenia treatments pioneered by Abram
Hoffer, M.D. Believing that large doses of niacin, Vitamin C, and
other nutrients might relieve the disease, Hoffer conducted controlled
trials in which neither the patients nor the doctors knew who was
getting real vitamins and who was taking fakes. Although patients
with established cases of the disease were unaffected, those in
its early stages showed dramatic improvement. Although subsequent
trials by other researchers failed the later trials either were
poorly planned or failed to include early-stage patients. At this
point, the majority of mainstream physicians still regard the treatments
as unproven, even though many patients swear by them.
Diabetes: Years ago, when doctors first learned how to feed
seriously ill patients intravenously; the early IV formulas did
not include trace amounts of chromium, an essential nutrient. Many
of these patients mysteriously developed a diabetes-like disorder
which, as it turned out, was a direct result of a chromium deficiency.
Since then, researchers have found that daily intake of 200 micrograms
of chromium picolinate can provide significant relief from diabetes,
reducing the patient's need for insulin and oral diabetes drugs.
A Chinese study found that between 200 and 1,000 micrograms a day
improved blood sugar levels, serum cholesterol, and total metabolic
control of the disease. Although conclusive proof is still lacking,
chromium picolinate may have other benefits as well. It has been
prescribed for obesity, insomnia, depression, acne and fatigue,
and some advocates say it can even promote longevity.
High Cholesterol: A form of the B-complex vitamin niacin
has long been an accepted remedy for high cholesterol levels. Dubbed
nicotinic acid, prescribed under the brand names Nicolar and Nicobid,
it is taken in doses of 250 to 500 milligrams per day.
Who Should
Avoid This Therapy?
Almost everyone
can increase his/her vitamin/mineral intake to therapeutic levels
without fear of harmful consequences. However, if you are taking
the blood thinning drug warfarin (Coumadin), you should avoid Vitamin
E supplements unless your doctor approves. Some reports suggest
that the vitamin may cause bleeding under such circumstances. Another
precaution: Vitamin E may interact with iron, so it is probably
best not to take them at the same time of day.
Benefits
Vitamin E:
Even large doses of Vitamin E are relatively safe, and most adults
can handle up to 1,000 IU with little or no harmful effects. There
have been a few scattered reports of a fatigue and weakness among
persons taking 800 IU a day, but the symptoms cleared up as soon
as supplements were stopped.
Folic Acid: While 400 micrograms of folic acid is considered
safe for most people, large doses can pose a problem for the elderly,
who frequently suffer from a deficiency of Vitamin B12. Folic acid
can hide the signs of this deficiency which, left unchecked, can
progress to irreversible nerve damage. To eliminate the danger,
simply take B12 supplements along with the folic acid. Folic acid
can also pose a problem for people taking an anti-seizure medication
such as dilantin or phenobarbitral. Each of these drugs causes a
folic acid deficiency that needs to be remedied. However, a return
to normal folic acid levels will increase the amount of drug needed
to prevent seizures. To side-step the problem, doctors now prescribe
the drugs and folic acid together. If you are not already taking
this combination, you will need to see your doctor for a dosage
adjustment when you begin taking the supplement.
Niacin: The high doses of niacin used in the treatment of
schizophrenia (usually several grams a day) pose a slight risk of
liver damage. It is best to take them under the supervision of a
physician who will have regular liver function tests performed.
If you have diabetes, you also face the possibility of an increase
in blood sugar levels when taking niacin. Unlike regular niacin,
the nicotinic acid form has a variety of potential side-effects,
including darkening of the skin or urine, diarrhoea, dry skin, eye
disorders, flushing, gout, headache, indigestion, irregular heartbeat,
itching, low blood pressure, low urine output, muscle pain, tingling,
ulcers, vomiting, warts, and yellow skin and eyes.
Chromium: Doses of as much as 1,000 micrograms a day (5 times
the maximum recommended allowance) have failed to produce side effects
in major clinical trials. Nevertheless, there have been a few isolated
reports that suggest some very minor degree of risk. Among the reported
reactions were 'disturbed thinking' and mental slowness. One woman
taking 600 micrograms a day suffered chronic kidney failure. Another
developed kidney and liver problems after taking 1,200 to 2,400
micrograms a day for 5 months. Also, if you have diabetes, do not
forget that chromium supplements can decrease the need for insulin
or oral medication, and could lead to an unhealthy drop in blood
sugar levels unless your medication dosage is reduced-all the more
reason to check with your doctor when you begin taking chromium.
