What is melatonin?

Melatonin is a hormone manufactured by serotonin and secreted by the pineal gland. It plays a key role as the biological timekeeper of hormone secretion, also known as the circadian rhythm.

How does melatonin work?

When an individual on a normal circadian rhythm is exposed to darkness, melatonin is released. Melatonin in the body reduces alertness levels and promotes relaxation. The end result is sleep. Upon exposure to light, melatonin levels drop off and the individual begins to become more alert and awake.

Melatonin and Jet Lag

Jet lag occurs when the body crosses time zones and has to adjust to the new zone; the greater the distance, the greater the effects of jet lag. Melatonin can be used to help prevent jet lag before it occurs. The theory is simple: If jet lag occurs as the body is trying to adjust, adjust the body before jet lag occurs.

Melatonin and Insomnia

Melatonin supplementation works ideally when levels normally produced by the pineal gland are low. If insomnia occurs as a result of naturally low melatonin levels, melatonin supplementation may be recommended.
