Melatonin shortens the time for falling asleep and alleviates the subjective sensation of jetlag.
Melatonin is a natural hormone that regulates the human biological clock. Melatonin is a hormone produced in the brain by the pineal gland from the amino acid tryptophan. The synthesis and release of melatonin are stimulated by darkness and suppressed by light, suggesting the involvement of melatonin in circadian rhythm and regulation of diverse body functions. Levels of melatonin in the blood are highest prior to bedtime. Synthetic melatonin supplements have been used for a variety of medical conditions, most notably for disorders related to sleep. Melatonin possesses antioxidant activity, and many of its proposed therapeutic or preventive uses are based on this property.
Shortens the time need for falling asleep.
Promotes a healthy sleep pattern.
Improves sleep quality.
Alleviates the subjective sensation of jetlag.
Can slow the aging process.
The ability to fall asleep or to go back quickly to sleep after interruptions, can be supported by taking melatonin supplements. Some studies with older and younger people have shown that consuming a small amount of melatonin accelerates the fall asleep and thereby improves the quality of sleep. These benefits have been noted in people with regular sleeping problems, as noted in people with occasional sleeping problems.
Stress can engender problems to fall asleep and frequent awakening during the night. In such situations melatonin may improve sleep quality by shortening the time you need to fall asleep.
Jet lag: If you work in night shifts or frequently fly across time zones, melatonin may reduce your jet lag feeling, to get you back into a regular sleep routine. Studies with flight attendants and people who fly a lot showed that supplements containing melatonin contribute to alleviate the subjective sensation of jetlag.
Anti-aging agent: studies have shown that melatonin is one of the best antioxidants. Mid-90s it became known that melatonin protects cells against aggressive free radicals and thereby slows the aging process.
Melatonin releases from the pineal gland, reaching its peak at night to help maintain healthy cell health throughout the body. Secretion of melatonin declines significantly with age, as the pineal gland becomes calcified. Jet lag, shift work, and poor vision can disrupt melatonin cycles.
Melatonin keeps our circadian cycle in tune. Not only does this hormone work to maintain cell health, it appears to regulate a system of self-repair and regeneration. As melatonin diminishes with age, our biological functions are impaired. Melatonin also has strong antioxidant properties. It directly scavenges both hydroxyl and peroxyl free radicals, and it does so more effectively than most other antioxidants. It also greatly potentiates the efficiency of other endogenous and exogenous antioxidants. Melatonin is especially important for protecting cellular DNA against peroxynitrite damage by inhibiting peroxynitrite free radical reactions. Some research has found that melatonin increases the speed of falling asleep and adds to the quality of sleep in about 60% of people who use it.
