Melatonin is a naturally occurring hormone produced by the
pineal gland that plays a role in the regulation of the sleep-wake cycle. It is
secreted by the pineal gland after your body senses the fall of darkness at the
end of each day, and keeps your body synchronized with the rhythms of day and
night. It is also a powerful antioxidant that supports immune system function.
As we age, Melatonin levels decline, so supplementation is necessary to provide
optimal levels of this important hormone. Scientists believe this reduction is
the reason why older adults have more trouble sleeping than younger people.
LifeSource Vitamins' Melatonin is a synthetic dietary supplement. Natural
Melatonin is normally derived from animal pineal tissue, but concerns have
arisen over the survival of unwanted microbes during the manufacturing process.
LifeSource Vitamins would rather be cautious, so we only offer the safe,
synthetic form of this nutrient.
Why take it?
Studies suggest that... supplements can hasten sleep and ease
jet lag, without the hazards or side effects of prescription sleeping
pills." Melatonin may have many other uses and has been reported to make
people feel better, strengthen the immune system, and reduce free radicals in
the body. Current research is underway to determine Melatonin's effect as an
anti-oxidant, immno-modulator in cancer, delayed sleep-phase disorders, and jet
lag. Tests are still under way so there is much to still be learned about
Melatonin and its effects on the human body.
Who benefits the most?
Travelers and people suffering from mild sleep disorders.
According to Newsweek, a typical comment from discussion groups on the Internet
is, "'Folks, I've tried Melatonin and it's great. It has ...restored my
sleep cycle, given me lots of energy.'"
Are there any side effects?
According to one report, "10 percent of the users said
the hormone did nothing for them, and another 10 percent complained of side
effects such as nightmares, headaches, morning grogginess, mild depression, and
low sex drive. In past studies, researchers have given people up to 600 to
3,000 times the usual doses - without causing any toxicity."
What additional benefits are there and how reliable are these
"In test-tube and animal experiments, researchers have
found that it protects cells, strengthens the immune system and slows the
growth of some tumors." Tests with laboratory mice suggest that Melatonin
might also reduce the effects of aging - but remember, these results are very
preliminary. "...Some experts are appalled to see so many people toying
with such a potent hormone. One concern is that high doses, while causing no
immediate harm, could have unknown long-term effects. 'Even one milligram, the
smallest commercially available dose, is at least three times higher than the
normal amount in the body.'"
Should certain people avoid it?
Yes. "Those include women who are pregnant or nursing
(since no one knows how excessive exposure to the hormone might affect a fetus
or infant); people with severe allergies or autoimmune diseases (Melatonin
could exacerbate such conditions by stimulating the immune system); people with
immune-system cancers such as lymphoma or leukemia (for the same reason), and
healthy children (who already produce it in abundance). Women trying to conceive
should also think twice about taking the hormone, since high doses can act as a
contraceptive." As with any substance introduced into your body, if you
have a medical condition you should always consult your physician first before
Will Melatonin extend my lifespan?
There are no human studies to support this contention. In
tests on both rats and mice Melatonin caused a significant 20% increase in
their lifespan. If Melatonin does allow you to live longer and healthier it
could do so because Melatonin may reduce free radical damage; stimulate an
aging immune system; protect the cardiovascular system; preserve a youthful
circadian rhythm; stimulate the production of growth hormone.
Will Melatonin enhance my sex life?
There is no evidence to support this claim as it relates to
humans. However, a 1995 rodent study suggests that taking small amounts of
Melatonin on a regular basis may prevent the age-related decline in
testosterone levels, allowing men to be more active sexually in their later
Is Melatonin safe?
Melatonin is one of the least toxic substances known. People
have taken as much as 6 grams (600 to 3000 times the normal dosage) of the
substance in carefully monitored studies with no sign of toxicity. Only four
complaints regarding Melatonin have been report to the FDA (USA's Food and Drug
Administration). The only consistent side effect of high doses has been
drowsiness and a slower reaction time. In the most extensive clinical trial to
date a high dose of 75 milligrams of Melatonin per day was given to 1400 women
in the Netherlands for up to four years with no ill effects. The FDA reports
that in the more than two years Melatonin has been available for sale
over-the-counter in the United States, no alarming side effects have been
