Melatonin is an indoleamine neurohormone found across plants and animals, produced endogenously from serotonin (5-HT) and secreted in animals as a regulatory signal for synchronization of the circadian rhythm and the sleep-wake cycle. The melatonin receptor system, consisting of the MEL-1A-R, MEL-1B-R, and MT3 subtypes, demonstrates particular plasticity and modularity - antagonists such as Luzindole (sc-202700) and 2-Phenylmelatonin (sc-203466) show modification of systemic responses to the Melatonin signal without impeding activation of the receptors by Melatonin.


Powerful antioxidant activity is associated with Melatonin, and it is known to provide protection to lipids, proteins, and DNA against oxidative damage. Several antioxidant enzymes are shown to be upregulated by Melatonin, including glutathione peroxidase, superoxide dismutases, and catalase. Melatonin also scavenges free radicals as a terminal antioxidant, reacting to generate stable end products and terminate radical chain reactions. Free movement through the blood-brain barrier positions Melatonin as a particularly significant endogenous antioxidant. Melatonin is a rat NOS1 (nNOS) inhibitor. Melatonin is an activator of MEL-1A-R and MEL-1B-R.

Melatonin, chemically N-acetyl-5-methoxytryptamine,is a substance found in animals, plants, fungi and bacteria. In animals it is a hormone that anticipates the daily onset of darkness;however in other organisms it may have different functions. Likewise, the synthesis of melatonin in animals differs from that in other organisms. In animals, melatonin is involved in the entrainment (synchronization) of the circadian rhythms of physiological functions including sleep timing, blood pressure regulation, seasonal reproduction and many others.Many of melatonin's biological effects in animals are produced through activation of melatonin receptors,while others aRe due to its role as a pervasive and powerful antioxidant,with a particular role in the protection of nuclear and mitochondrial DNA.


Melatonine is a hormone, secreted by the pineal gland in the brain that helps regulate other hormones and maintains the body's circadian rhythm. The circadian rhythm is an internal 24-hour time-keeping system that plays a critical role in determining when we fall asleep and when we wake up. Darkness stimulates the production of melatonin while light suppresses its activity. Exposure to excessive light in the evening or too little light during the day can disrupt the body's normal melatonin cycles. For example, jet lag, shift work, and poor vision can disrupt melatonin cycles. Melatonin is a hormone found naturally in the body. Melatonin used as medicine is usually made synthetically in a laboratory. It is most commonly available in pill form, but melatonin is also available in forms that can be placed in the cheek or under the tongue. This allows the melatonin to be absorbed directly into the body. People use melatonin to adjust the body's internal clock. It is used for jet lag, for adjusting sleep-wake cycles in people whose daily work schedule changes (shift-work disorder), and for helping blind people establish a day and night cycle.

Melatonin is also used for the inability to fall asleep (insomnia); delayed sleep phase syndrome (DSPS); rapid eye movement sleep behavior disorder (RBD); insomnia associated with attention deficit-hyperactivity disorder (ADHD); insomnia due to certain high blood pressure medications called beta-blockers; and sleep problems in children with developmental disorders including autism, cerebral palsy, and intellectual disabilities. It is also used as a sleep aid after discontinuing the use of benzodiazepine drugs and to reduce the side effects of stopping smoking. The hormone can be used as a sleep aid and in the treatment of some sleep disorders. It can be taken orally in liquid form as well as capsules or tablets in immediate- or prolonged-release form. It is also available in a form to be used sublingually, and as transdermal patches. Melatonin is sold over-the-counter in the U.S. and Canada. In other countries it may require a prescription or it may be unavailable.




How Does Melatonin Work?

Natural melatonin is a highly lipid soluble hormone produced in the pineal gland in the brain. It is synthesized from the amino acid tryptophan and then released into the blood and cerebrospinal fluid, crossing the blood-brain barrier. It sends messages to the melatonin receptor agonist in the brain and other areas of the body to help control the sleep and wake cycles.

Does melatonin help you sleep? When taken as supplement, the function of melatonin is to mimic the effects of the natural hormone. Drowsiness generally occurs within 30 minutes after taking melatonin. However, taking melatonin right before bed may not be the best strategy for all sleep disorders. Ask your doctor about the best method of dosing melatonin. Melatonin does not work for everyone.




1) Melatonin can effectively improve sleep quality
2) Melatonin can improve the functional status of the whole body
3) Melatonin can improve human immunity, prevent depression, Alzheimer's syndrome, cataracts, for the treatment of glaucoma also had a marked effect.
4) Melatonin can increase the body's immune system, auxiliary cancer, enhance physical fitness.
5) Melatonin has strong antioxidant effects

6)Improve sleep dosage (0.1 ~ 0.3 mg), and can shorten the awakening time and sleeping time before sleep, improve sleep quality, sleep wake up significantly reduced, short shallow sleep stage, extending deep sleep stage, in the morning wake up threshold value.Has the strong adjust time difference function




Sleep Aid

The hormone melatonin plays a role in your natural sleep-wake cycle. Natural levels of melatonin in the blood are highest at night. Some research suggests that melatonin supplements taken at the right time might be helpful in treating jet lag or other sleep disorders that involve poor alignment of your natural biological clock with the night-day pattern around you. Melatonin might also reduce the time it takes to fall asleep - although this effect is typically mild.

Melatonin is a natural hormone made by your body's pineal (pih-knee-uhl) gland. This is a pea-sized gland located just above the middle of the brain. During the day the pineal is inactive. When the sun goes down and darkness occurs, the pineal is "turned on" by the SCN and begins to actively produce melatonin, which is released into the blood. Usually, this occurs around 9 pm. As a result, melatonin levels in the blood rise sharply and you begin to feel less alert. Sleep becomes more inviting. Melatonin levels in the blood stay elevated for about 12 hours - all through the night - before the light of a new day when they fall back to low daytime levels by about 9 am. Daytime levels of melatonin are barely detectable.
