Bio-identical hormones have the same chemical
structure as hormones that are made by the human body. The
difference between natural or bio-identical versus synthetic is in
the molecular structure of the hormone.
In order for a replacement hormone to fully replicate the function
of hormones that were originally produced and present in the human
body, the chemical structure must exactly match the original.
Structural differences that exist between human (bio-identical) and
synthetic (non bio-identical) hormones may be responsible for side
effects that are experienced when non-bio-identical (synthetic)
hormones are used for replacement therapy. Synthetic hormones are
produced by changing the molecular structure of the natural hormone
to create a product that can be patented by a manufacturer. Mass
production of synthetic hormones is very profitable.
Your hormones function as a web or network. Each hormone relates to
and amplifies the effect of other hormones. An example of this is
the melatonin/thyroid connection. Italian researchers found that
among perimenopausal and menopausal women melatonin at bedtime
caused an increase in thyroid hormone as well as a general
improvement of mood and a significant mitigation of depression.
Optimal levels of all of your hormones are needed for you to achieve
optimal health.
Hormone replacement therapy should be to provide an adequate supply
of the deficient hormone in a form that is as close as possible to
that which the body originally produced, therefore resulting in
normal physiologic effects. Every person is unique. Therefore, it is
a sensible approach for health-care professionals and patients to
work together to customize hormone replacement therapy.
The precise components of each person's therapy are determined after
consultation and evaluation of laboratory testing. Lab studies are
done on a blood sample to assess the baseline hormone levels.
Bio-identical hormones can be compounded in the needed strength and
dosage form and administered via the most appropriate route to meet
each individual's needs.
Compounding pharmacies make your prescription for you and you only.
Made from plant extractions, they are an exact replica of your own
hormones, thus bio-identical. The key to effective hormone
replacement therapy, in summary, is individuality. Fixed doses do
not allow for individualized, tailor-made treatment.
Goals of bio-identical hormone replacement therapy include:
Alleviation of the symptoms caused by the natural decrease
in production of hormones by the body.
Re-establishing the protective benefits which were
originally provided by naturally occurring hormones.
Decreasing the diseases of aging such as cardiovascular
disease, dementia and osteoporosis.
Improving the quality of life long-term.
The major hormones that decrease with aging include:
Estrogen
Estrogen refers to a group of similar hormones produced in the body.
The main three are estrone (E1), estradiol (E2), and estriol (E3).
Estradiol is produced mainly by the ovaries and, of the three, it is
most stimulating to the breast tissue. Estrone is produced by the
adrenal glands and fat cells and when the ovaries fail (menopause)
it becomes the most prevalent estrogen. Estriol is produced in large
quantities in pregnancy and is also the main circulating estrogen in
young women. It is least stimulating to breast tissue. Estriol is
produced in the body from estrone and estradiol.
Estrogen protects against heart disease, stroke, osteoporosis,
Alzheimer's disease and memory disorders. It protects against
vaginal atrophy, urinary incontinence, and prevents symptoms of
menopause, including hot flashes and temperature disregulation. It
improves balance by improving the visual somatosensory system in the
central nervous system. Estrogen deficiency results in urogenital
atrophy, incontinence, sagging skin in the breasts, increased skin
wrinkles of the face, fatigue, depression, mood swings and decreased
libido. It is of extreme importance that the estrogen prescribed be
a natural estrogen and not a synthetic estrogen. The synthetic
estrogens have been shown to be harmful. We only prescribe natural
hormones and never use the cancer causing synthetic hormones (such
as Premarin). For optimal protection, natural estrogen
supplementation should be balanced by natural progesterone
supplementation.
Progesterone
Progesterone is primarily produced by the corpus luteum in the ovary
just prior to and after ovulation. It is also produced in large
quantities by the placenta during pregnancy and in small quantities
by the adrenal glands. Progesterone reduces symptoms of premenstrual
syndrome. It protects against uterine and breast cancers,
osteoporosis, fibrocystic disease and ovarian cysts. It dramatically
decreases menopausal symptoms. Most U.S. physicians prescribe
synthetic progestins (Provera) which cause such side effects as
bloating, headaches, fatigue and weight gain. The natural
progesterone must be prescribed in place of the synthetic progestin
to avoid the side effects and protect against cancer. We emphasize
the use of natural hormones and not synthetic hormones, which have
been proven time and time again to cause significant side effects.
Testosterone
Testosterone in men is mainly produced by the testicles and in
smaller quantities by the adrenal glands. In women, testosterone is
produced in both the ovaries and the adrenal glands. Testosterone
contributes to muscle mass, strength and endurance, decreased fat,
increased exercise tolerance, enhancement of well-being and
psychological status. Testosterone protects against cardiovascular
disease, hypertension, body fat and arthritis. It leads to improved
lean muscle mass, increased bone density, decrease in cholesterol,
improved skin tone, improved healing capacity, and increased libido
and sexual performance. It prolongs the quality of life by
decreasing the diseases of aging, as does estrogen in the female.
Testosterone is also present and extremely important in the female
as well as the male, making supplementation absolutely recommended
for men and women.
DHEA
DHEA is a hormone secreted by the adrenal glands. This hormone is a
precursor to other sex hormones. In addition to having its own
hormone effect, it results in a shift to an anabolic or protein
building state. It reduces cardiovascular risk by increasing
lipolysis or breakdown of fat. It also stimulates the immune system,
restores sexual vitality, improves mood, decreases cholesterol and
body fat. Recent studies point to DHEA as an anti-stress hormone,
reversing the effects of stress on the immune system.
Pregnenolone
Pregnenolone is produced in the adrenal glands. It is also produced
in the brain, liver, ovaries, testicles, and the myelin sheath of
nerves. Other hormones such as DHEA, cortisol, progesterone,
testosterone, and estrogens are made from pregnenolone. Pregnenolone
may enhance mood, energy, memory and brain and nerve tissue repair.
This would be helpful for individuals dealing with autoimmune
disorders, chronic fatigue, and depression.
Thyroid
Thyroid refers to a group of metabolic hormones produced in the
body. The two main thyroid hormones are thyroxine or T4, and
triiodothyronine or T3. T4 is produced by the thyroid gland. It is
the inactive thyroid hormone in the body. T3 is produced in the
brain and liver via the conversion of T4. It is the active form of
thyroid hormone in the body.
Thyroid hormone regulates temperature, metabolism and cerebral
function. It contributes to energy levels, temperature regulation
and body warmth. It increases fat breakdown, resulting in weight
loss as well as lower cholesterol. It protects against
cardiovascular disease and improves cerebral metabolism. It helps to
prevent cognitive impairment. Thyroid hormone is probably the safest
and most beneficial cholesterol lowering agent, yet it is
infrequently used for this!
Melatonin
Melatonin is secreted by the pineal gland. It is a circadian rhythm
hormone - thereby affecting the patterns of sleep. Research has
shown that the cells of the body rejuvenate and repair during the
deeper stages of sleep. It is during the deeper stages of sleep that
the body produces natural killer cells or CD4 cells. Melatonin
increases the deep stage of sleep and stage IV sleep, thereby
increasing and enhancing immunity. Improved sleep patterns serve to
energize the body and improve mood. Melatonin has powerful
antioxidant effects which accounts for disease prevention qualities.
Melatonin has tremendous cancer prevention effects due to its
enhancement of the immune system. Melatonin deficiency results in
poor sleep, jet lag, irritability, hypersensitivity and premature
aging.
Hydrocortisone
Hydrocortisone is produced by the adrenal glands. Hydrocortisone
helps boost the immune system to assist in recovery from infections,
illness, or stress. Hydrocortisone may be beneficial in treating
autoimmune disorders such as Crohn's, multiple sclerosis, lupus,
fibromyalgia, and rheumatoid arthritis.
