Melatonin
Melatonin is a neurohormone, secreted by the pineal gland in the brain, that regulates the sleep/wake cycle. Light suppresses melatonin synthesis. The primary use of melatonin as a supplement is to normalize abnormal sleep patterns.
Melatonin helps control sleep and waking patterns. It can be taken as a pill to help with sleep problems, including jet lag, shift work and insomnia.
Melatonin supplementation may help you fall asleep faster and stay asleep longer ensuring a better quality sleep.
