is Melatonin and what source does it come from?
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 Nutrition’s 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 Nutrition would rather
be cautious, so we only offer the safe, synthetic form of this nutrient.
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.
benefits the most?
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.'"
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."
additional benefits are there and how reliable are these claims?
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.'"
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
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.
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 years.
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 reported.
