Vitamins and their Importance in Health
and Disease
The word ‘Vitamine’ meaning a vital amine was proposed by a Polish
Researcher, Dr. Cacimir
Funk, in 1911 to designate a new food substance which cured beri-beri.
Other terms were
proposed as new factors were discovered. But the word vitamin , with the
final ‘e’ dropped, met
with popular favour.
Vitamins are potent organic compounds which are found in small
concentrations in foods. They
perform specific and vital functions in the body chemistry. They are like
electric sparks which
help to run human motors. Except for a few exceptions, they cannot be
manufactured or
synthesized by the organism and their absence or improper absorption
results in specific
deficiency disease. It is not possible to sustain life without all the
essential vitamins. In their
natural state they are found in minute quantities in organic foods. WE
must obtain them from
these foods or in dietary supplements.
Vitamins, which are of several kinds, differ from each other in
physiological function, in chemical
structure and in their distribution in food. They are broadly divided into
two categories, namely,
fat-soluble and water-soluble. Vitamins A, D, E and K are all soluble in
fat and fat solvents and
are therefore, known as fat-soluble. They are not easily lost by ordinary
cooking methods and
they can be stored in the body to some extent, mostly in the liver. They
are measured in
international units. Vitamin B Complex and C are water soluble. They are
dissolved easily in
cooking water. A portion of these vitamins may actually be destroyed by
heating.
They cannot be stored in body and hence they have to be taken daily in
foods. Any extra
quantity taken in any one day is eliminated as waste. Their values are
given in milligrams and
micrograms, whichever is appropriate.
Vitamins, used therapeutically, can be of immense help in fighting disease
and speeding
recovery. They can be used in two ways, namely, correcting deficiencies
and treating disease in
place of drugs. Latest researches indicate that many vitamins taken in
large doses far above the
actual nutritional needs, can have a miraculous healing effect in a wide
range of common
complaints and illnesses. Vitamin therapy has a distinct advantage over
drug therapy. While
drugs are always toxic and have many undesirable side effects, vitamins ,
as a rule are non-toxic
and safe.
The various functions of common vitamins, their deficiency symptoms,
natural sources, daily
requirements and their therapeutic uses are discussed in brief as follows
:
-
Beta Carotene:
In the last few years increasing numbers of reports have
suggested that the use of Beta Carotene may act to prevent the
development of various malignancies. Beta Carotene and other similar
compounds have differentiating properties that appear to affect cell
growth and maturation. Beta Carotene is not toxic to the liver even in
high doses in contrast to Vitamin A. Large doses of Beta Carotene will
increase the body's demands for Vitamin E; therefore, those of you on
50,000 to 100,000 units of beta carotene per day will need to also
increase your vitamin E to 1,000 to 2,000 units per day. The definitive
role of beta carotene/vitamin E is yet to be understood, but there is
sufficient reason to use beta carotene in a dose of 50,000 units per
day. There is no need to supplement this with carrot juice or vitamin A.
Beta carotene, like vitamin A and E is stored in the liver. Current
clinical trials in prevention of cervix cancer and cancer of the lung
and breast are using beta carotene. This may also be helpful in the
prevention of colon cancer and melanoma.

VITAMIN E:
Please read the above. Vitamin E is an important anti-oxidant. It acts
as a free radical scavenger to prevent the byproducts of chemical-cell
interaction to cause cell damage. Free radicals are likely responsible
for all or most of the degenerative diseases e.g. arthritis, heart
disease, cancer, senility etc. The absorption or scavenging of free
radicals would protect our cells from this type of injury. Other free
radical scavengers include zinc, vitamin C, and selenium.
Studies have reported vitamin E to protect against some of the
toxicities of ionizing radiation. Vitamin E may help to decrease the
toxicity of certain chemotherapy drugs. Adriamycin is an important
anti-cancer drug with potential major toxicity to the heart. The use of
1000 to 2,000 units of vitamin E per day may help to decrease this
toxicity. Vitamin E may decrease some of the harmful effects of solar
radiation on the skin. As cited above it works well in conjunction with
beta carotene. Vitamin E appears to have stabilizing effect on the
vascular system and is useful in decreasing menopausal and premenstrual
symptoms. It is useful in decreasing leg cramps occurring especially at
night. Vitamin E can be used in lotions or creams to protect the skin or
to treat for burns. It is also helpful to treat burns secondary to
radiation therapy. I have also used it with good results in patients
with dermatitis resulting from poor blood circulation i.e. stasis
dermatitis. It is commonly prescribed for topical use in pregnant women
to prevent stretch marks on the abdomen. More recently it has been used
to prevent or treat mucositis resulting from chemotherapy. I advise
patients to bite into a 1000 unit capsule and swish the vitamin E around
the mouth and over the mucous membranes lining the cheeks. This is done
three to four times a day. You can also use liquid vitamin E to do this.
-
B COMPLEX:
The B complexes are important membrane stabilizers. They are natural
tranquilizers or anti-stress vitamins because of this property. They are
important vitamins to help nerve function. The B complex vitamins
contain PABA which is important in protecting the skin against the
harmful effects of Ultra-violet radiation. PABA is an excellent UV
screening agent and helps to protect against the development of skin
cancer or sun-induced skin damage e.g. wrinkling and solar keratoses.
Fair complexioned people should avoid sun exposure and should use sun-
blockers with at least a 15 factor as well as use B complex orally. Such
people are actinic or sun sensitive and are at a greater risk for the
development of skin cancers of all types. People with red hair, blue or
green eyes tend to be sun sensitive (actinic sensitive). Women using
oral contraceptives increase their utilization of the B vitamins and
need to supplement their diet with B complex. Patient under high stress
should do the same. The B vitamins are water soluble. They are not
stored in the body as are beta carotene and vitamin E. B complex must be
taken with food already in the stomach. If taken on an empty stomach,
pain and nausea are not uncommon. The use of B complex in a dose of 100
mg once to three times a day with meals is recommended per patient
tolerance. If the B complex is being absorbed the urine will be bright
yellow and have a pungent smell due to the riboflavonoids present. This
is to be expected and should not cause alarm. If no change in urine
color is noted then suspect that your brand of B complex is not being
absorbed by your body- change brands.
-
VITAMIN C:
This vitamin is important for tissue healing. Patients with peptic
ulcers will heal faster on vitamin C than those without extra vitamin C.
As mentioned previously, vitamin C is an anti-oxidant. It is also water
soluble as B complex. I advise that it be used in doses of 2,000 to
6,000 mg after each meal to take advantage of its anti-oxidant effects.
I would start with 1,000 mg after each meal and increase slowly up to
6,000 mg after each meal. Side-effects of large doses include diarrhea
and flatulence. Studies in Canada show a decrease number of colon polyps
in patients taking high doses of vitamin C. Such polyps are precursors
for colon cancer. If we can decrease polyp formation with vitamin C
perhaps we can decrease colon cancer as well. The use of vitamin C in
this capacity should accompany a very low fat diet that is high in
dietary fiber. Smoking and alcohol consumption will increase the
excretion of vitamin C. Alcohol will actually deplete all of the water
soluble vitamins. Vitamin C has been touted by Pauling and Cameron to
decrease cancer growth and cause remissions in cancer patients. I have
not seen any evidence in all of the studies published to warrant that
conclusion. The studies published by Pauling and Cameron were
scientifically unsound and poorly controlled. Major trials using high
dose I.V. vitamin C fail to confirm any anti- cancer effect of this
vitamin in patients with established cancer.
High dose vitamin C may be a problem in patients with a tendency to
kidney stone formation. Check with your physician if this is your
situation.
In patients receiving iron supplements to help treat iron deficiency,
the use of vitamin C taken at the same time as the iron medicine will
greatly enhance the absorption of iron. Vitamin C will help with wound
healing and healing of burns. It improves the strength of the walls of
the blood vessels and may help decrease the easy bruising seen with some
patients. Vitamin C in topical form to prevent sunburn and to absorb the
ultraviolet rays will soon be available.
Vitamin C may help people with low back pain and arthritis due to its
anti- oxidant effects. This and other vitamins need to be taken over
long periods of time. These substances work over time -- be patient.
-
SELENIUM:
This is an anti-oxidant with activity as a free radical
scavenger. Populations with high blood selenium levels are found to have
lower death rates due to cancer. Mormons have high selenium blood levels
perhaps related to their diet. Cancer patients have low selenium blood
levels. Selenium works in harmony with vitamin E. Selenium toxicity can
occur and the dose of selenium should be close to 100 MICROGRAMS (not
milligrams) per day.
-
CALCIUM-MAGNESIUM:
Calcium is deficient in most of our diets. This deficiency is
most prevalent in women who have had children and have never
supplemented their own diets with calcium. Calcium consumption along
with exercise is the best means to prevent calcium deficiency. Once
calcium is lost and signs of osteopenia develop the medical problem may
be hard to reverse. Collapse of bone and fractures commonly of the
pelvis may occur in such individuals. When people "shrink" with age it
is due to vertebral compression fractures caused by osteopenia, commonly
referred to as osteoporosis. Bone density studies will detect patients
having osteopenia. Calcium, like B complex acts as a membrane stabilizer
and natural tranquilizer as does magnesium and potassium. Calcium and
magnesium should be taken together in a ratio of 2:1. A daily intake of
Calcium of 1,000 to 1,500 mg is reasonable. Calcium/magnesium may be
taken at bedtime to promote sleep. Magnesium in the form of magnesium
oxide in combination with vitamin B-6 has been shown to dissolve certain
types of kidney stones (calcium oxalate stones). This preparation is
called Beelith and is taken twice a day. It is also helpful in patients
with chronic constipation since magnesium salts act as cathartics.
During pregnancy the intake of calcium and magnesium should be increased
to prevent deficiency in mother and child. Patients with potassium
deficiency should always be checked for magnesium deficiency. In the
presence of magnesium depletion, it is very difficult to replete
potassium stores. I have used a calcium citrate source containing
vitamin D to enhance calcium absorption. This is an effervescent
formulation and it is taken as two tablets dissolved in a glass of cold
water per day. Calcium citrate is better absorbed and utilized than
calcium carbonate. The use of fluoride in a liquid formulation
(potassium fluoride 180 mg/cc) help bind calcium in the bones. Fluoride
drops are taken as 1 drop in juice or water three times per day. This is
a prescription item and must be made up by the pharmacist. The dose can
be slowly increased per the physician. Fluoride in this concentration
can irritate the gastric lining. Slow increases in dose are important to
prevent this side-effect.
-
ZINC:
This element is important in wound healing. It also functions as
an anti- oxidant. It is helpful in the treatment of acne. It hastens
healing of peptic ulcer disease and burns. The recommended dose is 100
mg per day. Chelated zinc will not cause the gastrointestinal distress
the inorganic zinc will. Therefore, request a chelated zinc rather than
zinc sulfate.
