Vitamin
A: It
is a potent antioxidant with immune system enhancing
abilities. Some of the functions of Vitamin A are:
develops and maintains the epithelial tissue that lines the
inner and outer surfaces of the body. This includes
the mucous membranes, the lungs, skin, stomach, and the
urinary, digestive, and reproductive tracts. Essential for
night vision. Maintains
a healthy thymus gland, which controls the entire immune
system. Vitamin A is important
for the formation of bones and soft tissue, including tooth
enamel, and it protects against some cancers. It is
important in treating acne, treated topically and orally
with large doses of Vitamin A. It helps with hormonal
imbalances, which are associated with skin problems.
It also strengthens epithelial tissues, including the skin.
Birth
Defects: A deficiency of Vitamin
A is linked to birth defects. Expectant mothers
should use a multi-vitamin with a minimum of 2,000 I. U.’s,
and no more than 8,000 I. U.’s (excess Vitamin A in
pregnancy can also cause birth defects).
Asthma:
Vitamin A is important in maintaining healthy lung
tissue. It also helps reduce allergic reactions.
Allergies:
Vitamin
A helps
ensure proper immune antibodies (IGA) are present. This is
important in digestive dysbiosis, including parasite,
Candida, bacterial, and viral infections. Vitamin A
is important in correcting a leaky gut.
A leaky gut is
associated with such allergic reactions as migraine,
asthma, rheumatoid arthritis, irritable bowel, cystitis,
sinusitis, rhinitis, ear infections, dermatitis, hives, and
eczema. Side
Notes:
Beta-Carotene can be converted into Vitamin A.
Beta-Carotene is relatively non-toxic.
Vitamin A is important in calcium metabolism. A deficiency
in zinc will cause Vitamin A not to be metabolized, even
when there is an abundance of Vitamin A.
White
spots on the fingernails indicate a Zinc and Vitamin A
deficiency and suggest reduced immunity.
Toxicity:
Cracked lips, dry skin, headaches, thinning hair, and bone
pain are all signs of too much Vitamin A. These symptoms
are quickly reversed when Vitamin A levels are
reduced.
*Beta-Carotene
is a group of
carotenoids, which are found in dark green, yellow and dark
orange fruits and vegetables. It is a strong
antioxidant that has anti-cancer properties. One
molecule of Beta-Carotene can destroy 1,000 free
radicals. It protects the skin from harmful
ultraviolet (UV) light. Women with low levels of
Beta-Carotene in their cervical tissues are at risk for
developing cervical cancer. Albert Einstein College
of Medicine, The
Essential Vitamin and Mineral Guide,
E. Somer, M. A., R.
D.
A
nineteen-year study involving 3,000 men shows carotenoids
(especially Beta-Carotene) may be capable of significantly
reducing the incidence of lung cancer in both smokers and
non-smokers. Dr. Braly's Food Allergy
and Nutrition
Revolution, J.
Braly, M.D., Keats Publishing, New Canaan, Conn.,
1992. Side
Notes:
Beta-Carotene can be used as a precursor to Vitamin
A. Vitamin E and Selenium enhance the role of
Beta-Carotene. Toxicity:
The only side effect of consuming too much Beta-Carotene is
a yellowing of the skin. This condition disappears
once Beta-Carotene is discontinued.
*Vitamin
D is
produced by the body after exposure to sunlight. It
helps maintain healthy nerve and muscle systems by
regulating the level of circulating calcium. Calcium
is essential for proper nerve transmission and muscle
function. A deficiency in Vitamin D can cause
degeneration of bones and possible hearing loss if the
small bones in the ear are involved.
*Vitamin
E is another
major antioxidant. It protects cells and tissues from
oxidative stress and free radical damage. It also
protects the pituitary and adrenal hormones, fatty acids,
and myelin sheaths surrounding nerves and genetic material
in DNA from free radical damage. Studies done in
Israel show Vitamin E can reduce the symptoms of
osteoarthritis. Braly.
As an
antioxidant, Vitamin E helps slow down the aging
process. Vitamin E increases and maintains proper
brain function. Recent studies conducted at Columbia
University have shown Vitamin E to slow down the effects of
Alzheimer’s.
Researchers
at Tufts University found that by supplementing the diet
with 200 I.U.'s of Vitamin E, control groups had
a 65
percent increase in immune fighting
abilities. According to research
done at Harvard School of Public Health, people who
supplement their diets with 100 I.U.'s of Vitamin E reduced
their risk of heart disease by 40 percent (100 I.U.'s is
seven times the RDA for Vitamin E). It prevents
abnormal blood clotting and increases the efficiency of
muscles, including the heart, by reducing oxygen
requirements.
Researchers
at Duke University have demonstrated that Vitamin E acts as
a potent antioxidant to counter the toxic effects of air
pollution. The
amount needed to combat air pollution, including ozone and
nitrous oxide, is six times the RDA! Once again, this
should serve notice that the RDA levels are inadequate in
today's society. Vitamin E is effective in
reducing tension in the lower extremities, which is
associated with intermittent claudication and heart
disease. Vitamin E
also relieves restless leg syndrome or "the
fidgets". A deficiency in Vitamin E can
lead to heart disease, muscular dystrophy, nervous system
disorders, anemia, liver damage, and birth defects.
Side
Notes:
Selenium enhances the effects of Vitamin E. A Zinc
deficiency increases the need for more Vitamin E.
Vitamin E may be necessary for the synthesis of Vitamin
B-12. Vitamin E helps protect the body from the toxic
effects of lead and mercury. Smokers definitely need
to take extra Vitamin E. Research done at the
University of California shows Vitamin E and Vitamin C
levels are reduced by exposure to cigarette smoke.

Journal Of Clinical Nutrition, 63:559-565,
(1996). Studies have also
demonstrated a 45 percent reduction in lung cancer in those
individuals who take vitamin
supplements. S.

Lung Cancer Risk in the U. S. Nonsmokers, Journal
of the National Cancer Institute (USA), 86:33-38,
(1994).
Toxicity:
Unlike other fat-soluble vitamins, Vitamin E is relatively
non-toxic. Vitamin E taken in very high dosages can
cause interference with Vitamin K and lead to prolonged
bleeding times. However Vitamin E is safe when taken
in dosages several times higher than the RDA (which it is
recommend you do). *The body stores fat-soluble vitamins,
which include Vitamins A, D, E, K, and Beta-Carotene.
Because of this, an overdose is possible when taking these
vitamins. However, the side effects of vitamin
toxicity are quickly eliminated once they are
discontinued.
The Water
Soluble Vitamins: Vitamin
B-1, also
known as Thiamin, is needed to metabolize carbohydrates,
fats and proteins. It is important for proper cell
function, especially nerve cells. It is involved in
the production of acetylcholine. This nerve chemical
is directly related to memory and physical, as well as
mental energy. A
deficiency of Vitamin B-1 can lead to fatigue, mental
confusion, emaciation, depression, irritability, upset
stomach, nausea, and tingling in the
extremities. Vitamin B-1 has been reported
to be deficient in almost 50 percent of the elderly. Could
this be one of the reasons pre-senile dementia and
Alzheimer’s disease have increased so dramatically over the
last few decades? Side
Note: Diets
high in simple sugars, including alcohol, will increase the
chances of having a Vitamin B-1 deficiency.
The tannins in tea
inhibit Vitamin B-1 absorption.
Riboflavin or
Vitamin B-2 is responsible for the
metabolism of carbohydrates, fats and proteins.
Vitamin
B-2 is involved in producing the neurotransmitters.
Neurotransmitters are brain chemicals that are responsible
for sleeping, mental and physical energy, happiness, and
mental acuity (more on neurotransmitters and
depression under Amino
Acids). A
deficiency of Vitamin B-2 can cause soreness and burning of
the lips, mouth, and tongue, sensitivity to light, itching
and burning eyes, and cracks in the corners of the
mouth. Side
Notes:
Vitamin B-2 can help curb the craving for sweets, and is
needed for the synthesis of Vitamin B-6. Vitamin B-2
is needed to convert the amino acid Tryptophan to Niacin
(B-3). Vitamin B-2 is not absorbed very well and any
excess will turn the urine a bright fluorescent
yellow. Toxicity:
None.
Niacin or
Vitamin B-3 plays an important role in
mental illness. Orthomolecular physicians have used Niacin
to treat schizophrenia, anxiety and depression.
Vitamin B-3 is a by-product from the metabolism of
Tryptophan. Some psychiatric disorders are caused by
a genetic inability to breakdown or absorb
Tryptophan. This can lead to aggressive behavior,
restlessness, hyperactivity, and insomnia.
*Large
daily doses of Niacin can decrease blood cholesterol,
LDL-cholesterol and triglycerides, while increasing the
good cholesterol, HDL. Niacin increases the
circulation. This helps prevent blood clots and
arteriolosclerosis, which can lead to heart disease and
stroke. A deficiency of Niacin cause weakness,
dry skin, lethargy, headaches, irritability, loss of
memory, depression, delirium, insomnia, and
disorientation. Side
Notes:
Large doses of Vitamin B-3 can cause a flushing of the
skin. This can be prevented by starting off with 25
mgs. a day, gradually increasing the dosage over a period
of days. The flushing is due to the release of
cellular histamine. Niacin acts as a wonderful
sedative to calm nerves and help with sleep. Vitamin
B-6 is needed to convert Tryptophan to Niacin.
Toxicity:
*Daily doses
of 1,000 mg. appear to be quite safe, and large doses are
needed to treat high cholesterol. For high
cholesterol, its best to use timed release Niacin.
For psychiatric disorders, including anxiety, depression
and insomnia, it is best to use a special version of
Vitamin B-3 known as Niacinamide.
Pantothenic
Acid or Vitamin B5 is crucial for managing stress
and boosting the immune system. Vitamin B-5 is needed
by all cells in the body. It is needed for normal
functioning of the gastrointestinal tract. It
converts carbohydrates, fats and proteins into
energy. Vitamin B-5 is needed to produce adrenal
hormones which play an important role in how well we deal
with stress. In fact,
Vitamin B-5 is sometimes referred to as the "anti-stress"
vitamin. Vitamin B5 can help reduce anxiety and may
play a significant role in
depression. It helps convert choline
into acetylcholine which is responsible for memory. A
deficiency in Vitamin B-5 can lead to fatigue, depression,
irritability, digestive problems, upper respiratory
infections, dermatitis, muscle cramps, and loss of
sensation in the extremities. Side notes:
Vitamin B-5, along with Vitamin C, helps to reduce uric
acid levels. Increased uric acid levels are
associated with gouty arthritis. Vitamin B5 helps
boost endurance by manufacturing ATP, an essential chemical
for cellular energy. Toxicity:
Large doses may cause diarrhea.
Pyridoxine or
Vitamin B-6 may be the most important B
vitamin. It is involved in more bodily functions than
any other vitamin. Vitamin
B-6 is crucial for making neurotransmitters, including
Serotonin, epinephrine and Norepinephrine.
Neurotransmitters are brain chemicals, which regulate our
energy, moods, sleep, memory, drive, and
ambition. It inhibits the
formation of homocysteine, a toxic chemical associated with
heart disease. It is involved in the synthesis of DNA
and RNA, which make up the genetic blue print of
cells. It helps metabolize essential fatty
acids. As a major antioxidant, Vitamin B-6 helps
prevent the destruction caused by free
radicals. Vitamin B6 helps produce hydrochloric acid
which is crucial for proper digestion. The formation
of hemoglobin is dependent on Vitamin B-6. A Vitamin
B-6 deficiency can cause anemia even if normal iron levels
are present. A deficiency of Vitamin B-6 can cause
depression, insomnia, fatigue, tingling and numbness in the
extremities, increased susceptibility to infections,
nausea, kidney stones, and anemia. Side
Notes:
Vitamin B-6 may be suppressed by certain medications,
including oral contraceptives and estrogen. ymptoms
associated with Vitamin B-6 deficiency include premenstrual
syndrome, depression, irritability, tension, headaches,
fluid retention, and acne, and may be reduced by taking
Vitamin B-6. It can also serve as a natural
diuretic. Vitamin B6 can alleviate carpal tunnel
(tingling or pain in the wrists and hands). Some
asthmatics have a malfunction in the way they assimilate
Vitamin B-6 and process Tryptophan. Supplementing with
250-500 mg. of Vitamin B-6 a day can help with symptoms of
asthma. Vitamin B-6 is needed for proper magnesium
levels in red blood cells. Orthomolecular physicians use
mega doses of Vitamin B-6 to treat
schizophrenia. Vitamin B-6 stimulates IGA antibodies
which help prevent tooth decay.
Cobalamin or
Vitamin B-12 is the only B vitamin that is
stored by the body. A Vitamin B-12 deficiency occurs
only in malnutrition, malabsorption or other impediments to
proper digestion. Vitamin B12 is important in the
growth of children. It is responsible in the
replication of the genetic material in all the cells, and
therefore, is essential for the development and maintenance
of all cells. Vitamin B12 helps form the myelin
sheath that insulates nerve processes. This sheath
allows rapid communication from one cell to another.
A deficiency of B-12 can cause a reduction in mental
acuity, evidenced by poor memory. Side
Notes: Alzheimer’s and senile
dementia are two diseases that are associated with memory
loss, confusion and nerve damage. Both diseases can
be due to a deficiency of Vitamin B-12. B12 is only
found in animal products (especially liver), and therefore,
vegetarians should supplement their diet with Vitamin
B-12. Anti-gout medications, anti-coagulant drugs and
potassium supplements may interfere with B-12 absorption,
and taking antacids will block the absorption of Vitamin
B-12! Calcium is necessary for normal absorption of
B-12. High doses of Folic Acid can mask the symptoms
of a Vitamin B-12 deficiency anemia. A Vitamin B-12
deficiency is usually caused by malabsorption, and is
mainly seen in elderly patients. Because this
deficiency is routinely seen in the elderly, I believe
everyone over the age of 60 should be taking extra Vitamin
B-12. Vegetarians are also more likely to have a B-12
deficiency, and therefore, should routinely supplement
their diet with B-12. Toxicity:
None.
Biotin-is
critical to the body's fat metabolism, and it aids in the
utilization of protein, Folic Acid, B-12, and Pantothenic
Acid. Sufficient quantities are needed for
healthy hair and nails. Biotin may help prevent hair
loss in some men. Biotin is also important in
promoting healthy bone marrow, nervous tissue and sweat
glands. A deficiency in Biotin can cause brittle
nails, hair loss and depression. Side
Notes: Saccharin inhibits the
absorption of Biotin. Raw egg whites, antibiotics and
sulfa drugs all prevent proper utilization of Biotin.
Due to poor absorption, infants are susceptible to a Biotin
deficiency. Symptoms of a deficiency include a dry,
scaly scalp and or face. This is known as seborrheic
dermatitis. A Biotin deficiency is considered rare,
and deficiency is usually seen in hospitalized patients on
intravenous feeding tubes, or patients taking large dosages
of antibiotics. Symptoms of a deficiency include
depression, dry skin, conjunctivitis, hair loss and color,
elevated cholesterol, anemia, loss of appetite, muscle
pain, numbness in the hands and feet, nausea, lethargy, and
enlargement of the liver. Toxicity:
None.
Choline: Is
essential for the health of the liver, gall bladder,
kidneys, and nerves. It helps with fat and
cholesterol metabolism. It prevents fat from
accumulating while helping fight fat build up in the
arteries and liver. Our bodies can make Choline from
Vitamin B-12, Folic acid, and an amino acid,
Methionine. Choline is essential for brain
development and proper liver function. A deficiency
in Choline may cause poor memory and mental fatigue.
Mega doses of Choline have been used to treat Alzheimer’s
disease, Huntington's disease, learning disabilities, and
Tardive Dyskenesia with varying degrees of
success. Toxicity:
None.
Ascorbic Acid
or Vitamin C produces and maintains
collagen, a protein that forms the foundation for
connective tissue. Connective tissue is the most
abundant tissue in the body. Vitamin C is important
in fighting bacterial infections, healing wounds,
preventing hemorrhaging, reducing allergy symptoms, and
helping to prevent heart disease. Vitamin C is a
potent antioxidant, which helps prevent free radical
damage. Vitamin C is a natural antihistamine, and can
reduce blood pressure in mild hypertension. Vitamin C
prevents the progression of cataracts, and helps regulate
blood sugar levels. Vitamin C may help improve
fertility, and helps regulate cholesterol so that it is
excreted out of the body. It lowers LDL (bad)
cholesterol, while raising the HDL (good)
cholesterol. Vitamin C
increases the immune system function, and is involved in
the formation of important stress hormones produced by the
adrenal glands. A deficiency in Vitamin
C can cause bleeding gums, loose teeth, dry, scaly skin;
tender joints, muscle cramps, poor wound healing, lethargy,
loss of appetite, depression, and swollen arms and
legs. Side
Notes: Vitamin C
is important in the conversion of Tryptophan to the brain
chemical (neurotransmitter) Serotonin. Low Serotonin
levels are linked to insomnia and depression. A
deficiency of Vitamin C causes an increase in urinary
excretion of Vitamin B-6 (also associated with making
neurotransmitters). Vitamin C helps prevent
toxicity of cadmium, a heavy metal that can increase the
risk of heart disease. Other heavy metals, including
mercury and copper, are also counter-acted by Vitamin
C. Aspirin, alcohol, antidepressants,
anti-coagulants, oral contraceptives, analgesics, and
steroids can all interfere with Vitamin C
absorption. Ester
C is
absorbed four times faster than regular ascorbic
acid. Most Vitamin C is lost in the
urine. Ester
C only loses
one-third the amount of ascorbic acid in
urination. Toxicity:
Pregnant women should not exceed 5,000 mg. of Vitamin C a
day. Large doses of Vitamin C can cause
diarrhea. Many nutritional experts, including this
author, recommend gradually increasing Vitamin C until you
have a loose stool. Then, reduce your Vitamin C intake 500
mg. at a time until you no longer have diarrhea. This
is your optimal dose.
Folic
Acid is
considered brain food. It is involved with energy
production, synthesis of DNA, formation of red blood cells,
and metabolism of all amino acids.
Folic Acid is involved in the production of the
neurotransmitters, including
Serotonin. Low Folic Acid levels
are associated with an increase in homocysteine, an amino
acid linked to cardiovascular disease (Vitamin B-6, Folic
Acid and Vitamin B-12 all help reduce homocysteine
levels). A deficiency in Folic Acid (one the most
common vitamin deficiencies), will produce macrocytic
anemia, digestive disorders, heart palpitations, weight
loss, poor appetite, headaches, irritability, depression,
insomnia, and mood swings. Side
Notes:
A sore, red tongue may indicate a Folic Acid
deficiency. Folic Acid needs Vitamins B-12, B-3 and C
to be converted into its active form. Folic Acid can
improve the birth weight, neurological development and
prevent neural tube defects in infants. Women who are
trying to get pregnant and expectant mothers should take a
multi-vitamin with at least 400 mcg. of Folic Acid. A
condition known as neural tube defect or Spinal Bifida
occurs when the baby's spinal cord and brain don't close
properly. If the opening occurs at the top of the
neural tube, the brain never develops properly and the baby
will die in a matter of hours. Toxicity:
Large doses of
Folic Acid can mask a Vitamin B-12 deficiency.
Inositol
is important in the
metabolism of fats, cholesterol, and in the proper function
of the kidneys and liver. It is vital for hair
growth, and prevents hardening of the arteries.
Inositol is needed for the synthesis of lecithin, which
helps remove fats from the liver. Along with Gamma
Amino Butyric Acid (GABA), an amino acid, Inositol may help
reduce anxiety. Side
Notes:
Caffeine may decrease Inositol stores. There is no
known deficiency or toxicity for Inositol.
Para-amino
benzoic Acid or PABA is needed to form red and white
blood cells, which in turn, form essential B
vitamins. PABA is used in suntan lotion to help block
harmful UV rays and prevent sunburn. PABA has
anti-viral properties, and has been reported to help in
treating Rocky Mountain Spotted Fever.
Side
Notes:
PABA may help restore gray hair to its natural color.
PABA and sulfa drugs cancel each other out.
Toxicity:
Doses over 1,000 mg. can cause nausea and vomiting.
Minerals
Boron
is needed in trace
amounts for the proper absorption of calcium. A
recent study by the U. S. Department of Agriculture showed
women who consumed 3 mg. of Boron a day lost forty percent
less calcium and one-third less magnesium in their
urine. Toxicity:
Excessive amounts of Boron can cause nausea, diarrhea, skin
rashes, and fatigue.
Calcium
is the most
abundant mineral in the body. It comprises some two
to three pounds of total body weight, and is essential for
the formation of bones and teeth. Calcium regulates
heart rhythm, cellular metabolism, muscle coordination,
blood clotting, and nerve transmission. Adequate
intake of Calcium can help lower high blood pressure and
the incidence of heart disease. Calcium contributes
to the release of neurotransmitters that allow nerves to
transmit their messages. Calcium can have a calming
affect on the nervous system. A deficiency of Calcium
can result in hypertension, insomnia, osteoporosis, tetany
or muscle spasm, and periodontal disease.
Side
Notes:
The ratios for calcium-to-magnesium and for
calcium-to-phosphorous is important. It is
recommended for Calcium intake to be 2 to 1 or 1.5 to 1, to
Magnesium, and 2 to 1, 0r 3 to 1 for Phosphorous.
Vitamin D is needed for the absorption of Calcium.
Calcium absorption is decreased by high protein, fat and
phosphorous (junk food) diets. Chelated Calcium
(bound to a protein for easier absorption) and Magnesium
can help reduce aluminum and lead poisoning.
Toxicity:
Excessive (several grams a day) Calcium intake can cause
calcium deposits in the soft tissue, including the blood
vessels (arteriosclerosis) and kidneys (stones).
Oyster shell or bone meal calcium supplements often contain
high levels of toxic lead. Calcium citrate or
ascorbate is recommended, instead.
Chromium
is involved in the
metabolism of blood sugar (glucose). It is essential
in the synthesis of cholesterol, fats and protein.
Chromium helps stabilize blood sugar and insulin
levels. Proper interaction between blood sugar and
insulin insures proper protein production, reducing the
chance for fat storage. A deficiency in Chromium can
cause adult onset diabetes, hypoglycemia and coronary
artery disease. Side
Notes:
Ninety percent of the U. S. population is deficient in
Chromium! Diets high in simple sugars
increase the loss of Chromium, and a deficiency can cause a
craving for sugar. Zinc can inhibit Chromium
absorption; and should always be taken
separately. Toxicity:
None.
Copper
maintains the
sheath that wraps around nerves (myelin sheath) and
facilitates nerve communication. It plays a vital role in
regulating the neurotransmitters. Copper plays an
integral part in maintaining the cardiovascular and
skeletal systems as well. It is part of the
antioxidant enzyme Supraoxide Dismutase, and may help
protect cells from free radical damage. Copper helps
with the absorption of iron, and a deficiency in Copper can
lead to anemia, gray hair, heart disease, poor
concentration, numbness and tingling in the extremities,
decreased immunity, and possibly Scoliosis.
Side
Notes:
Cadmium, Molybdenum, and sulfate can interfere with Copper
absorption. A Niacin deficiency can cause an
elevation of Copper. Zinc and Copper impair the
absorption of one another. Toxicity:
Daily intake of 20 mg. or more can cause nausea and
vomiting. Wilson's disease is a genetic disorder
characterized by excessive accumulation of Copper in the
tissues, liver disease, mental retardation, tremors, and
loss of coordination.
Iron
is important in
formation of hemoglobin, oxygen use, energy production,
muscle function, thyroid function, and components of the
immune system, protein synthesis, normal growth, and mental
acuity. Side
Notes: Iron should not be
routinely supplemented. Blood tests are recommended
for those who may be deficient in Iron. The exception
in iron supplementation is for females who rigorously
exercise. Studies show only eight percent of the U.
S. population is deficient in Iron. However, twenty
percent of pre-menopausal, and as many as eighty percent of
females who exercise, are deficient in Iron.
Excessive amounts of Vitamin E and Zinc interfere with Iron
absorption. Vitamin C helps with the absorption of
Iron. Vitamin B-6 is needed for the Iron
containing-protein, hemoglobin. People suffering from
Candida and chronic herpes infection usually have a
deficiency in Iron. Toxicity:
Excessive amounts of Iron are associated for increased risk
of heart disease and can lead to decreased immunity, liver,
kidney, and lung disorders. If you suspect you have
an iron deficiency, talk to your health professional about
having blood tests done.
Magnesium
is one of the most
important minerals in the body. It is responsible for
proper enzyme activity, transmission of muscle and nerve
impulses, and aids in maintaining a proper pH
balance. It helps metabolize carbohydrates,
proteins, and fats into energy. Magnesium helps
synthesize the genetic material in cells, and helps to
remove toxic substances, such as aluminum and ammonia from
the body. Adequate amounts of magnesium are needed to
insure proper heart function. A deficiency of
magnesium may increase heart disease by decreasing free
radical damage. Calcium and magnesium help regulate
the heart rate. Magnesium relaxes smooth muscle,
including the heart, and calcium constricts or activates
smooth muscle. Magnesium plays a significant role in
regulating the neurotransmitters. A
deficiency in magnesium can cause depression, muscle
cramps, high blood pressure, heart disease and arrhythmia,
constipation, insomnia, loss of hair, confusion,
personality disorders, swollen gums, and loss of
appetite.
Side
Notes: Magnesium is a natural sedative
and can be used to treat muscle spasm, anxiety, depression,
insomnia, and constipation. It also helps with
intermittent claudicating, a condition caused by a
restriction of blood flow to the legs (I recommend Bilberry
and 600 mg. of magnesium). Magnesium is also
effective in relieving some of the symptoms associated with
premenstrual syndrome (PMS). Women who suffer from
PMS are usually deficient in magnesium (as is 80 percent of
the general population). New studies are validating
what many nutrition-oriented physicians have known for
years; a magnesium deficiency can trigger migraine
headaches. Magnesium helps relax constricted
bronchial tubes associated with asthma. In fact, a
combination of Vitamin B-6 and magnesium, along with
avoidance of wheat and dairy products has cured many of my
young asthmatic patients. High intake of calcium may
reduce magnesium absorption. Simple sugars deplete
the body of magnesium! So does stress, and magnesium
is a potent anti-depressant! Toxicity:
Symptoms of
magnesium toxicity include nausea, lethargy and difficulty
in breathing. Magnesium supplemented above 600 mg.
can cause loose stools and diarrhea, but this is quickly
remedied by decreasing the dosage.
Manganese
aids in the
development of mother's milk and is important for normal
bone and tissue growth. It is involved in the
production of cellular energy. It metabolizes fats
and proteins and is essential in maintaining a healthy
nervous system. Manganese is needed in order to
synthesize thiamin, and it works in coordination with the
other B vitamins to reduce the effects of stress. A
deficiency of manganese can cause fatigue, impaired
fertility, retarded growth, birth defects, seizures, and
bone malformations. Side Notes: Calcium,
Copper, Iron, Manganese, and Zinc all compete for
absorption in the small intestine, and large doses of one
these nutrients may reduce the absorption of the
others. Many of
my patients who suffer from Chronic Fatigue and
Fibromyalgia are deficient in
manganese
Toxicity:
None.
Molybdenum
aids in the
conversion of purines to uric acid and allows the body to
use nitrogen. It is important in sulphite
detoxification and promotes normal cell function.
Molybdenum deficiency can cause stunted growth, loss of
appetite, and impotence in older males.
Side
Notes:
Excessive copper may interfere with molybdenum
absorption. Molybdenum works with Vitamin B-2 in the
conversion of food to energy. Molybdenum can help
reduce symptoms associated with sulfite
sensitivities. I had a patient who broke out in a
rash every time she ate foods containing the preservative
Sulphite. A hair analysis revealed a molybdenum
deficiency. Once her molybdenum levels were
normalized, she was once again tolerant of
sulphites. Toxicity:
High dosages can cause symptoms similar to gout, joint pain
and swelling.
Phosphorus
is needed for
healthy teeth, proper bone and cell growth, and helps
regulate heart contractions. A deficiency in
phosphorus is quite rare. It is found in most foods,
especially meats, dairy products and junk
foods. Side
Notes:
Excessive amounts of phosphorus can interfere with calcium
absorption. Junk foods, especially sodas, are loaded with
preservatives and large amounts of phosphorus.
Toxicity:
As above.
Potassium,
Sodium, and Chloride help to regulate the nervous
system and heart rhythm. They regulate sodium and
water balance in the body. Potassium, sodium and
chloride are all closely related to one another.
These three minerals are known as electrolytes
due to their
electrical charge. They are responsible for maintaining a
proper pH (along with calcium and magnesium). Excess
sodium can cause an elevation in blood pressure.
Potassium helps lower blood pressure and can reduce the
risk of stroke. Chloride helps make up the digestive
enzyme hydrochloric acid. Hydrochloric acid helps digest
food, destroys harmful intestinal "bugs", and synthesizes
Vitamin B-12. Chronic diarrhea, vomiting, heat
stroke, prolonged use of diuretics and kidney disease can a
cause deficiency of all three of these minerals. A
potassium deficiency manifests itself as irregular heart
beats, sterility, muscle weakness, apathy, paralysis, and
confusion. A chloride deficiency can lead to
alkalosis, an imbalance in the body's pH system. This
imbalance can cause vomiting and more diarrhea. A
sodium deficiency is rare, but can occur after long periods
of sweating, fasting and or diarrhea.
Side
Notes:
Sodium increases urinary calcium loss, while potassium
decreases urinary calcium loss. Potassium and
magnesium are synergetic in lowering blood pressure and,
therefore, should be taken together.
Selenium
is an important
antioxidant that protects the body from free radical
damage. It is a component of glutathione peroxidase,
an enzyme essential for detoxification of cellular
debris. Selenium, along with other antioxidants,
especially Vitamin E, combats free radicals that can cause
heart disease. Selenium may help prevent certain
forms of cancer. Selenium may help those suffering
from autoimmune disorders such as rheumatoid arthritis. It
is an important component of the immune system. It helps
make thyroid hormones and essential fatty acids A
deficiency can cause birth defects, certain cancers,
fibrocystic disease, heart, and liver disease.
Toxicity:
Doses above 600 mg. can cause side effects that include,
tooth decay and periodontal disease.
Zinc
is important in
over ninety enzymatic pathways. Zinc facilitates
alcohol detoxification within the liver. It plays a
role in producing and digesting proteins. Zinc is
also important in maintaining normal blood levels of
vitamin a, boosting the immune system, healing wounds,
converting calories to energy, reducing low birth rates and
infant mortality, controlling blood cholesterol levels, and
in producing the prostaglandin hormones that regulate heart
rate, blood pressure, inflammation, and other
processes. A deficiency of zinc can lead to poor
taste, anorexia nervosa, anemia, slow growth, birth
defects, impaired nerve function, sterility, glucose
intolerance, mental disorders, dermatitis, hair loss, and
atherosclerosis. Side
Notes:
Excess copper can cause a zinc deficiency and vice
versa. Women who are pregnant accumulate excess
copper and become zinc-deficient. This can lead to
post-partum depression. Extra zinc, 50 mg, a day,
should be consumed by pregnant females to help avoid
unwanted post-partum depression. I don't recommend
prescription pre-natal vitamins, because they are too low
in the needed micronutrients, especially zinc and the B
vitamins. I encourage my pregnant patients to take a
high potency vitamin with a maximum of 10,000 I.U.’s of
Vitamin A. Doses of Vitamin A above 10,000 I.U.’s are
contraindicated and should be avoided. Zinc lozenges
have been shown to reduce the symptoms and duration of
colds by fifty percent. It is estimated that
sixty-eight percent of the population is deficient in zinc.
Zinc deficiency can cause depression, since it's necessary
for the production of the happy hormone, Dopamine.
Fingernails that contain white specks are indicative of a
zinc deficiency.
Vitamin/Mineral
IV Therapy
Clinical experience and recent research
has proven intravenous vitamin and mineral therapy to be
effective in treating FMS and CFS
patients.
Our practice
has been using vitamin/mineral IV therapy for the last 4
years. They're an important part of our FMS and CFS
program.
Nutritional
deficiencies are a major reason why Fibromyalgia patients
can't get well. We are only as healthy as the chemical,
cells, tissues, and organs that make up our bodies. Our
chronically ill patients, especially our FMS and CFS
patients, are deficient in several vitamins, minerals and
other essential nutrients.
A recently
published review of eighty-six FMS patients, seventy four
percent improved and most only needed four or fewer
treatments for optimal results. Side effects leading to
discontinuation of therapy occurred in four percent of the
participants. Prescriptions for anti-inflammatory
medications and muscle relaxants were virtually
eliminated.
(Reed JC.
Magnesium therapy in musculoskeletal pain
syndromes-retrospective review of clinical results.
Magnesium
Trace Elem 1990;9:330.)
Alan Gaby,
M.D., a well respected resource in the complimentary
medicine movement, is largely responsible for promoting
this therapy. Dr. Gaby first learned of nutritional IV
therapy from Dr. John Meyers. Dr. Meyers was a well known
physician in Baltimore, Maryland who created the "Meyers
cocktail." This cocktail contains vitamins and minerals as
described below. There are now hundreds maybe thousands of
doctors using this cocktail. Dr. Gaby has personally
overseen the administration of fifteen thousand plus of
these "Meyers cocktail" IV therapies. Several prominent
physicians who specialize in FMS and CFS including Majid
Ali, author of "The Canary and Chronic Fatigue" and Dr.
Teitelbaum author of "From Fatigued to
Fantastic."
Vitamin C and
intravenous therapy
Use of
vitamin C infusions originates with the work of the late
Fred Klenner, M.D. He's one of the unsung heroes in
medicine. Dr. Klenner, in the small town of
Reidsvill, North Carolina, discovered the efficacy and
safety of IV vitamin C. He practiced and taught this
technique for over 40 years, and achieved tremendous
success in the treatment of refractatory infections and
autoimmune diseases. His life's work was recently
published in a fascinating book called The Clinical Guide
to the Use of Vitamin C. In our experience,
intravenous vitamin C is a powerful weapon against CFS and
FMS. We have seen numerous patients obtain dramatic
relief from pain, fatigue, insomnia, and depression from
the use of this modality.
Vitamin and
mineral IV’s are usually recommended because we've found
them to be extremely valuable in accelerating the healing
process. Individuals with chronic illnesses like FMS
and CFS usually have a problem with digestion; bloating,
gas, indigestion, irritable bowel, malabsorption, Leaky Gut
Syndrome, and yeast overgrowth. Because of this they don't
digest and absorb the essential nutrients found in foods or
vitamins.
Without these
essential nutrients, chronically ill patients will stay
chronically ill!
Prescription
medications often further deplete vital nutrients that the
patient needs for optimal health. A case in point is a deficiency
in magnesium.
It
is estimated that up to 80% of those with FMS/CFS are
deficient in magnesium. A deficiency in this essential
mineral can cause the following symptoms, muscle pain,
joint pain, headaches, fatigue, insomnia, heart
arrhythmias, depression, constipation, irritable bowel, and
leg cramps. Does any of this sound familiar? Yet, most
physicians don’t know this and therefore don’t recommend
supplementing magnesium.
Amino
Acids
There are
twenty amino acids. Nine of these are known as essential
amino acids. Essential amino acids can't be made by the
body and must be obtained from our diet. Non-essential
amino acids can be manufactured from within our own cells.
Individual amino acids are joined together in sequential
chains to form proteins. Protein, the body’s building
material, is essential to every cell and makes-up our
muscles, hair, bones, collagen, and connective
tissue. Essential and non-essential amino acids are
involved in every bodily function. They are the raw
materials for the reproduction and growth of every cell.
Amino acids are in every bone, organ (including the brain),
muscle, and most every hormone. Amino acids are also needed
to make enzymes. Enzymes are protein molecules that
coordinate thousands of chemical reactions that take place
in the body. Enzymes are essential for breaking down and
digesting carbohydrates, proteins and
fats.
*A
few distinctions are needed in order to understand and use
amino acids properly. Amino acids can occur in two
forms, a “D-form” and an “L-form”. These two forms are
mirror images of one another. The “L-form” is available in
the foods we eat, and it is considered the most absorbable
form. The white, crystalline free-form amino acids derived
from brown rice protein are the purest supplement
available. In a natural state all amino acids are in the
“L-form”. “D-forms’ can be formed by bacteria, tissue
catabolism, or synthetically. Most “D-forms” are not
available for protein synthesis and can be detrimental to
normal enzyme functions. However, DL-Phenylalanine as
discussed below is the exception. DL-Phenylalanine inhibits
the breakdown of endorphin and enkephalin limiting
enzymes.

Individual
Amino Acids
Amino acids
can be taken as a blend to shore-up any underlying
nutritional deficiencies. Always use “free form” (L- forms)
amino acids. Taken individually, amino acids act like
a drug to produce specific reactions. It’s best to take
single amino acids on an empty stomach; 30 minutes before
or 1 hour after eating. Individuals with malabsorption
syndrome, irritable bowel, leaky gut, and chronic illnesses
are wise to take an amino acid blend in addition to any
single amino acids they may be taking. The Essential
Therapeutics FMS/CFS Formula contains all of the essential
amino acids.
Here are some
of the amino acids and how they are used in nutritional
medicine.
L-Tryptophan
has already been
discussed in chapter 8, "First Things
First."
L-Carnitine
and
energy
Carnitine is
produced by combining two other amino acids, Methionine and
Lysine. Carnitine helps transport fats into the cell
for the mitochondria to use as energy. The
mitochondria burn fatty acids during physical activity,
which makes L-Carnitine a valuable tool for reducing weight
and reducing the risk of fat build-up in heart
muscle. Its efficient use of fats helps the body
lower cholesterol, triglycerides and possibly the risk of
heart attack. The consumption of alcohol can cause a
build up of fat in the liver. L-Carnitine inhibits
alcohol-induced fat build up in the liver. L-Carnitine
helps boost cellular energy and has shown to be helpful in
reducing the fatigue associated with
CFS.
L-Cysteine
and
detoxification
Cysteine is
formed from the amino acid Methionine and plays an
important role in detoxifying the body. Cysteine is
the precursor to the most abundant and most important amino
acid in the body, glutathione. Glutathione is a tripeptide
of glutamine, (Glutamic acid), cysteine, and
glycine.
Cysteine
destroys free radicals, chelates (removes) heavy metals
from the body, guard’s cells, including heart and liver
cells, from toxic chemicals like alcohol, xenobiotics and
other damaging substances. Glutathione and cysteine are
effective in reducing or eliminating skin conditions, such
as psoriasis, acne, liver spots and eczema. Those with
respiratory problems, asthma, bronchitis, and allergies may
benefit from taking a specialized form o cysteine known as
N- acetyl-cysteine. *N-acetyl-cysteine has proven to be
helpful for wide variety of respiratory
problems.

pharmacotherapeutic issues. Ann Pharmocother 1995;
29(12):1263-73.
I prescribe
L-Cysteine and L-Methionine to my patients with aluminum
toxicity and poor liver function. Usually used in a
combination formula. If taking by itself use 500-1000 mg a
day on an empty stomach.
Gamma-Amino
Butyric Acid (GABA) and anxiety
GABA, which
can be formed from the amino acid Glutamine, has a calming
effect on the brain, similar to valium and other
tranquilizers without the side effects. GABA, used in
combination with the B vitamins Niacinamide (a form of
Vitamin B-3) and Inositol, can alleviate anxiety and panic
attacks. Many of my patients are surprised by the
effectiveness of GABA in treating their anxiety and panic
attacks.
For anxiety
start with 500mg 2-3 times a day (or as needed) on an empty
stomach. Some individuals may need up to a 1,000 2-3 a
day.
L-Glutamine
and intestinal permeability
Glutamine is
converted to Glutamic acid in the brain. Glutamic
acid increases neuronal activity, detoxifies ammonia (an
abundant waste product in the body) from cells, and like
glucose, is used to feed the brain. L-glutamine plays
an important role in intestinal maintenance and repair.
Glutamine is the major energy source of the intestines. It
is one of the most important nutrients for the cells that
line the colon. Individuals with intestinal problems,
including Crohn's disease, colitis, irritable bowel,
intestinal permeability, yeast overgrowth, and food
allergies, especially need glutamine
supplementation. Weir,

The
Ultimate Nutrition Glutamine The Essential Nonessential
Amino Acid by Judy Shabert, M.D, R.D. and
Nancy Ehrlich. Avery Publishing
Glutamine is
one of the three amino acids that form glutathione.
Glutathione is a powerful antioxidant and plays an
important role in the detoxification system of the body. It
helps clear unwanted toxins through the kidneys and
liver.
It helps
reduce sugar cravings and acts as an appetite
suppressor.
Glutamine is
the precursor to two very important neurotransmitters,
Glutamic acid (glutamate) and gamma amino butyric acid
(GABA). Glutamate is an excitatory neurotransmitter while
GABA is an inhibitory (relaxing)
neurotransmitter.
Children who
took glutamine supplements showed increased mental
abilities and tested higher on I.Q.
tests.
Usual dose
is 500-1,000 mg twice a day on an empty
stomach.
L-Glycine and
detoxification
Glycine is
another inhibitory amino acid. It can be used to
reduce the symptoms of bipolar depression, epilepsy, and
nervous tics. Glycine is also important in
neutralizing toxic chemicals (especially alcohol). It
helps synthesize Glutathione. It's been used in the
treatment of depression and in the inhibition of
epilepsy. J.
Balch, M.
D. and P. Balch, C. N. C., Prescription For Nutritional
Healing, Avery
Publishing, Garden City Park, New York, p.29,
1990.
Usually
taken in a combination formula.
L-Histidine
and allergies
A histidine
imbalance can cause anxiety, schizophrenia, nausea
(particularly if pregnant), lethargy, fatigue, and anger.
Histidine is the precursor of histamine. Histamine is known
to play a role in allergic reactions (hay-fever) but also
acts as an inhibitory neurotransmitter. Histamine increases
alpha-wave activity within the brain. The alpha-wave is
associated with relaxation. When activated it helps
increase ones resistance to stress and
tension.
Histidine
improves digestion by increasing the production of stomach
acid. Usually taken in a combination
formula.
L-Lysine and
viruses
Lysine is
the essential component of all proteins and plays a major
role in soft tissue formation and repair. It is used
for in treating cold sores, and is one the most important
and cost efficient supplements I prescribe in treating
herpes viruses. L-lysine is one of the most effective
therapies for shingles. Cortisone only reduces the
itching, but it does nothing to rid the body of the skin
lesions. Taking steroids weakens the immune system
and can cause further outbreaks of the virus. Use the
natural antibiotic, anti-viral herb Echinacea along with
1,000 mg. of L-lysine and 25,000 I.U. of Vitamin A daily
for two weeks or until the lesions disappear. If you
easily bruise or your body has a difficult time healing
wounds, you're deficit in Lysine.
L-Methionine
and SAM
One of the
essential amino acids (the body can't manufacture it on its
own). Methionine is a crucial nutrient that allows
the body to digest fats, combat toxins, produce choline,
and deal with allergic reactions. It’s the precursor of
cysteine, glutathione and taurine, and contributes to the
production and regulation of insulin. Methionine is an
excellent chelator. Chemical chelators are able to attach
themselves to heavy metals like aluminum and lead and then
help escort them out of the body through detoxification
processes.
I prescribe
methionine to my patients with faulty detoxification
systems. People with chronic fatigue, fibromyalgia,
liver problems, and heavy metal or xenobiotics overload
need extra methionine.
Methionine
is the main chemical component of s-adenosyl-methionine
(SAM). SAM is involved in synthesizing neurotransmitters. A
deficiency of SAM can contribute to
depression.
A number of
studies have shown that supplementing SAM can increase
serotonin and dopamine. For more
information on SAM and depression please see chapter on
depression.
SAM and
FMS
Studies
involving FMS patients and SAM have shown dramatic
improvements in pain reduction. 8One study showed that
patients taking SAM for a period of 6 weeks had an
improvement of 40% in pain reduction and 35% improvement in
their depression.
*Grassetto M
and Varotto A (1994) Primary Fibromyalgia is responsive to
S-adenosyl-l-methionine. Current
Therapeutic Research, 55:
797-806.
Recommended
dose for methionine is 500-1,000mg a day on an empty
stomach. It may also be taken in a combination
formula.
Recommended
dose for SAM is 400-800mg a day.
DL-Phenylalanine
and pain control
This is a
combination of the D- and L-form of the amino
acid.
This
form of phenylalanine acts as a natural pain
reliever. DL-phenylalanine blocks the enzymes
responsible for the breakdown of endorphins and enkephlins.
Endorphins and enkephlins are a group of substances with in
the body that help relieve pain. Endorphins are similar in
chemical structure and actually far more powerful than the
drug known as morphine. Small cells throughout the nervous
system, brain, spinal cord and nerve endings are able to
produce these morphine-like
proteins.
It acts as
an appetite suppressant and mild stimulant.
Dl-phenylalanine has shown to be affective in helping
patients afflicted with Parkinson's disease. Although
caution is advised for individuals with high blood
pressure, DL-phenylalanine is an affective supplement in
treating musculoskeletal pains, including those associated
with FMS. Many of my Fibromyalgia and chronic pain
patients have benefited from taking
DL-Phenylalanine.
A clinical
study shows subjects taking DL-phenylalanine had a
remarkable improvement in their condition; improvements
were seen in 73 percent of low back pain suffers, 67
percent with migraines, 81 percent with osteoarthritis, and
81 percent with rheumatoid arthritis.
J.
Brawly, pg. 131.
For pain
control or as an antidepressant take 1,000-4,000 mg twice a
day on an empty stomach.
Phenylalanine
can elevate blood pressure and very high doses may cause
rapid heart beat; start with a low dose an increase to
higher doses only as needed and only if no side effects are
noticed.
L-Phenylalanine
and depression
Phenylalanine is an important
amino acid that is involved in the production of a
particular neurotransmitter known as catecholamines.
Catecholamines stimulate mental arousal, positive mood, and
the “fight or flight” response to stress. Phenylalanine
creates the following neurotransmitters, adrenaline,
epinephrine, norepinephrine and dopamine. These
neurotransmitters help to elevate mood, reduce depression,
pain, fatigue, and lethargy.
Phenylalanine is converted to
the non-essential amino acid Tyrosine. Individuals with a
rare but life threatening illness known as phenylketonuria
(PKU) can’t breakdown and convert phenylalanine into
tyrosine. The thyroid hormone thyroxin is made from
tyrosine (see below). Supplementing with phenylalanine and
tyrosine helps increase the thyroid gland and rate of
metabolism. This in turn helps mobilize and burn fat.
Phenylalanine curbs the appetite by stimulating a hormone
known as cholycystokinin (CCK), which tells the brain when
you’ve eaten enough.
As an
antidepressant use 1,000-4,000 mg twice a day on an empty
stomach.
Phenylalanine
can elevate blood pressure and very high doses may cause
rapid heart beat; start with a low dose an increase to
higher doses only as needed and only if no side effects are
noticed.
L-Tyrosine
and low thyroid
Tyrosine can
be a lifesaver for those suffering from depression.
It has helped people with depression that has been
resistant to all other medications. Tyrosine is effective
not only in treating depression, but also helps with those
suffering from fatigue and asthma. Tyrosine aids in the
production of the adrenal, thyroid, and pituitary
hormones. Many of my patients with low or hypothyroid
function have benefited from taking a special supplement
that contains L-tyrosine. Low energy, brittle nails,
cold hands and feet can mean a person is suffering from
adrenal hormone insufficiency. If so, these people
may benefit from taking L-tyrosine and along with an
adrenal extract supplement. Tyrosine, which can be produced
from phenylalanine, elevates mood, drive and ambition by
stimulating the neurotransmitters, norepinephrine,
epinephrine and dopamine.
Tyrosine can
also raise blood pressure so use caution. For low thyroid
supplement with 1,000 mg twice a day on an empty stomach.
For depression and fatigue use phenylalanine instead (see
above).
