| Human Growth Hormone | Human Growth Hormone (hGH) is produced by the pituitary gland. It is only available as a supplement by prescription. The effects of hGH are similar to those of DHEA. It will reduce signs of aging by increasing muscle, decreasing fat, and giving people a feeling of well-being and energy.
Growth hormone is a small protein molecule containing 191 amino acids in a single polypeptide chain. It is the most prevalent hormone secreted by the pituitary gland. Its rate of production is max during adolescence when accelerated growth occurs. Manufacturing price decreases 14% every decade in old age. Generally, it stays in prevalent supply waiting to be secreted into the body. For some cause yet to be identified, this all-important gland ceases to secrete the hormone, which tells the body to repair the cells. The body begins to age by procuration-decreased amounts of growth hormone over time. Daily secretion from the pituitary gland reduces with age. For example, a 60-year-old man secretes 25% of the hGH secreted by a young man.
The secretion diminution owing to deficit of instructions from the hypothalamus to growth hormone releasing hormones, which are, as their name implies, hormones, which act to release. Adding to this already decreasing dimension is the fact that senses situation for hGH also become desensitized after a certain age. This causes less growth hormone to be released.
Melatonin
Melatonin is produced naturally by the pineal gland in the brain. Melatonin declines with age in some people. It is over-the-counter supplement. Melatonin supplements have been touted as 'an anti-aging rememdy', a sleep remedy and an antioxidant. Melatonin is a hormone with strong antioxidant properties. It is reportedly an immune supporter, cancer fighter, heart helper and mood elevator and natural sleeping agent. The organ, which secretes melatonin, is the pineal gland, the timekeeper of the brain and that that controls our circadian rhythms. Dosage differs from body to body. Low dosages of 0.3 mg to l mg can reduce the time to fall asleep as well as increase the quality of sleep.
DHEA (dehydroepiandrosterone)
DHEA is an adrenal hormone that is the forerunner for steroid hormones such as estrogen and testosterone. DHEA declines precipitously with advancing age in both women and men. The researches have shown that oral DHEA can improve stress disorders, neurological function, immune function and that it can be protective against cardiovascular disease and even some types of cancer. DHEA is the most common of all steroids and is released from the adrenal glands. Cholesterol actually makes DHEA and is told to do so when the pituitary releases ACTH, which turns signals the cholesterol. DHEA helps to product estrogen, testosterone, progesterone and coritcosteroids. The decline of DHEA parallels that of growth hormone. By age 65, the body makes only 10-20% of DHEA that was made at the youth age.
