What is Melatonin?

A naturally occurring hormone (derived from serotonin)
that is both endocrine (enters the bloodstream from a pineal gland)
and paracrine (signaling cell phenomenon, as from the retina
when light is low, when the signal is "time to sleep").
Melatonin, besides being a sleep hormone, is a very powerful
antioxidant, anti-aging agent, immunoregulator, anti-depressant
and sexual dysfunction regulator.

Is Melatonin Safe to Take?

Yes. the 3mg dose has virtually no side effects, and does not also
affect the body's ability to produce its own melatonin.
Rather, in today's world where we are exposed to great amounts of
strong artificial light, our bodies will not produce the melatonin it
generally needs. Melatonin also plays a key role in memory and
our ability to learn quickly. Some very famous studies have been
made on melatonin (one by the Nobel Prize laureate Julius Axelrod)
where it was proven that melatonin plays a direct role in establishing
our sleep cycle and more. There are no toxic dangers at all, but it will
cause drowsiness, so one must not take it prior to driving or operating
mechanical equipment.
