Melatonin is a hormone made by the pineal gland, a small gland in the brain. Melatonin helps control your sleep and wake cycles. Very small amounts of it are found in foods such as meats, grains, fruits, and vegetables. Your body has its own internal clock that controls your natural cycle of sleeping and waking hours. In part, your body clock controls how much melatonin your body makes.
Normally, melatonin levels begin to rise in the mid- to late evening, remain high for most of the night, and then drop in the early morning hours. Light affects how much melatonin your body produces. During the shorter days of the winter months, your body may produce melatonin either earlier or later in the day than usual. This change can lead to symptoms of seasonal affective disorder (SAD), or winter depression.
Natural melatonin levels slowly drop with age. Some older adults make very small amounts of it or none at all. Can be used to treat jet lag or sleep problems (insomnia). Melatonin is a potent antioxidant that defends against free radicals and helps to support glutathione activity in the neural tissue.

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.
