Hormones and their Functions
Hormones and their Functions
ANTERIOR PITUITARY GLAND
Growth hormone (GH) Stimulates the growth of bone and soft tissue ; stimulates the synthesis of gluclose guring periods of fasting.
Prolactin stimulates the breast to develop and produce milk.
Thyroid-stimulating hormone(THS) stimulates the thyroid gland to produce thyroid hormones (T3 &T4)
Adrenocorticotropic hormone (ACTH) stimulates the adrenal cortex to secrete steroids, especially cortisol.
Follicle-stimulating hormone (FSH) stimulates development of ova and sprem.
Luteinizing hormone(LH) causes ovuation in women;stimulates secretion of progesterone in women and testosterone in men.
Posterior Pituitary Gland
Antidiuretic hormone(ADH) stimulates water reabsorption by kidneys; also constricts vessels.
Oxytocin contracts uterine muscle during labor; releases milk from the mammary glands.
HORMONES OF THE THYROID AND PARATHYROID GLANDS
Thyroid Hormones(T3 &T4) Triiodothyronine (T3) AND TETRAIODOTHYRONINE(T4) secreted by the thyroid gland; control metabolic rate and regulate growth and development.
Calcitonin secreted by thyroid gland ; decreases plasma levels of calcium
Parathyroid hormone(PTH) secreted by the parathyroid glands ; increases plasma calcium.
HORMONES OF THE ADRENAL GLAND
Catecholamines-epinephrine & norepinephrine stimulates fight or flight response.
Cortisol- glucocorticoid that helps regulate glucose, fat, and protein metabolism; is part of the stress response.
Aldosterone - Mineralocorticoid that causes the kidneys to reasbsorb sodium and water and excrete potassium; helps regulate fluid and electrolyte balance.
Sex Hormones - The androgens especially testosterone help develop the secondary sex characteristics in male and female.
HORMONES OF THE PANCREAS
Insulin secreted by beta cells of the islets of Langerhans;helps regulate the metabolism of carbohydrates, proteins and fats ; lowers blood glucose.
Glucagon seceted by alpha cells of the islets og Langerhans ; rises blood glucose levels.
Estrogens & progesterone secreted by the ovaries; to stimulate the development of the ova and development of secondary characteristics in the female.
Testosterone secreted primarily by the testes; chief male androgen; stimulates development of sperm and secondary sex characteristics in the male.
Thymosins stimulates maturation of the T lymphocytes.
Melatonin secreted by the pineal gland; helps set the biorhythms.

Estrogen is secreted by the ovaries. 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. Estrogen deficiency results in urogenital atrophy, incontinence, sagging skin in the breasts, increased skin wrinkles of the face, increased fatigue, repression, 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. For optimal protection, natural estrogen supplementation should be balanced by natural progesterone supplementation.
Testosterone is a hormone normally associated with men, but is also found in women. Testosterone is a hormone secreted by the adrenal glands, testes, and ovaries. It 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. Testosterone is the best hormone to increase collagen and elastin in the skin. 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 both men and women. Testosterone is the second most important hormone for energy and well being.
Progesterone is secreted by the ovaries and reduces symptoms of premature menstrual 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 which cause such side effects as bloating, headaches, fatigue and weight gain and most recently associated with increasing the risk of cancer. 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.
Thyroid hormone is a metabolic hormone secreted by the thyroid gland that regulates temperature, metabolism, and cerebral function. It contributes to energy levels and 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! More than any other hormone, the thyroid hormone is most responsible for improvement in energy and reducing fatigue.
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.
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 deepest 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.
