Melatonin is what your body secretes along with the circadian rhythm of your body. Now scientists say this hormone could reset the body's aging clock, turning back the ravages of time.
Humans like most animals produce the biggest supply of Melatonin in our early years. But the levels in our blood drop slightly before puberty and decline steadily into old age. Recent studies suggest that supplementing the hormone may bolster our immune systems, keep our cells from disintegrating, slow the growth of tumors and cataracts, and ward off heart disease. All that while helping us sleep better.
Through its actions on other hormones, it helps determine when people sleep and horses breed, when birds migrate, dogs shed their coats and certain frogs change color. But cellular biologists have recently discovered that melatonin has an even more basic function, which is to protect oxygen-based life from the toxic effects of...oxygen.
The process, known as oxidation, weakens our minds and muscles as we age, and contributes to at least 60 degenerative diseases, including cancer, heart disease and Alzheimer's. The body produces several enzymes to inhibit oxidation, and nutrients such as vitamin C, vitamin E and beta carotene can provide extra protection. But most of these so-called antioxidants work only in certain parts of certain cells. Melatonin readily permeates any cell in any part of the body- including the brain.
Melatonin may also help prevent cataracts, the cloudy lesions that appear on our eyes as oxidation damages cells in the lenses.
We also lose our immune function. The thymus gland shrinks over time, sapping our ability to generate infection-fighting T cells, and we produce fewer of the antibody molecules that bind with and neutralize foreign invaders, such as viruses and bacteria. Could all of this follow from a loss of melatonin? Test-tube studies have identified receptors, or specialized portals, for melatonin on the cells and glands of the immune system.
Melatonin could help us prevent, and even treat, the most common afflictions of old age. Autopsy studies suggest that pineal calcification (a condition that harens the gland and reduces melatonin output) is most common in countries with high rates of breast cancer and least common in counries where breast cancer is rare. By the same token, women taking chlorpromazine, an antipsychotic medication that raises melatonin levels, enjoy unusually low rates of the disease.
And Dr. James Jan of Van couver, British Columbia's Children's Hospital, has reported that bedtime doses of 2.5 to 10 milligrams help establish normal sleep patterns in kids with neurological problems such as autism, epilepsy, down syndrome and cerebral palsy. "We had tried everything, " Jan recalls of the first child he treated with melatonin, "but nothing worked." After one dose of the hormone, " the parents called me and said, 'It's a miracle! A miracle!' The child slept through the night."

Melatonin is certainly one of the highest growing non prescription drugs in the country. And if the research in this article is true there is many reasons to take it.
