Natural Source Of Melatonin
Melatonin, being a powerful substance, is one that should be used with caution
in cases of serious illness like cancer. Find out who else should be wary of
using this supplement, and a food source of melatonin that is a safer, more
natural alternative for those still interested in getting the benefits of
melatonin. And find out general dosage of melatonin needed for insomnia.
Melatonin is produced by the pineal gland. It is believed to play a role in anti
aging, as well as helping with jet lag and insomnia. But caution is well advised
with using melatonin as a supplement, given how powerful its effects are.
One of the problems with melatonin is that most of the studies were done on
animals, like rats, and not humans. Animal studies are used by the scientific
community to indicate whether a substance has promise, and can yield valuable
results even though they are ethically reprehensible and other alternatives
exist. One such study was done at the University of Texas Health Science Center.
Whilst it was funded by a grant from the California Walnut Industry, these
scientists were able to establish not only that walnuts contained melatonin, but
that it was able to be absorbed - at least by rats. But they believe humans
would also be able to absorb melatonin from walnuts. Unfortunately, they don't
know how many walnuts you'd have to eat to get the benefits they established as
a potential in this study. It might be a lot! But using food as a source of
melatonin is a good option given that it is much safer, particularly if
suffering from serious illnesses.
University of Texas scientists also found that melatonin had an antioxidant
effect. Antioxidants protect our cells from damage by oxidation. Antioxidants
slow down the aging process, and interestingly, melatonin levels often decrease
The antioxidant effect of melatonin has been presented before. Dr Reiter, also
of the University of Texas Health Science Center, believes it can protect the
central nervous system as well as the body generally from free radicals. He also
thinks melatonin can increase the body's own production of another antioxidant,
People who should not take melatonin supplements are:
* pregnant women
* breastfeeding mothers
* couples trying to conceive
* people with serious allergies
* HIV and cancer patients
Whilst it is not recommended that people with cancer take melatonin, this is
primarily for the reasons that not enough research has been done on humans, at
least according to Dr Kenneth Cooper. But some of the research that has been
done with people suggests that melatonin may be very helpful - if it is taken
with the supervision of a doctor. And herein lies the crux of the problem -
melatonin is a very powerful substance. Only small doses are needed to create
improvements. For example, Dr Cooper cites the example of dosages as small as 2
to 3 mg only, for some people suffering insomnia.
Overall, melatonin is very promising, and may well help people with serious
illnesses like cancer and multiple sclerosis. In the meantime, increasing our
dietary intake of foods like walnuts that potentially supply us with this
wonderful nutrient, may have a host of protective health benefits as well as
slowing down the aging process.
