The bioavailability of melatonin is between 2.5 and 50%. [6] [7] Melatonin is rapidly absorbed and distributed, reaching peak plasma concentrations after 60 minutes of administration, and is then eliminated. [6] Usual doses of exogenous melatonin of 1 to 12 mg produce melatonin concentrations 10 to 100 times higher than endogenous peak levels. [7]
Melatonin, an indoleamine, is a natural compound produced by various organisms, including bacteria and eukaryotes. [1] Its discovery in 1958 by Aaron B. Lerner and colleagues stemmed from the isolation of a substance from the pineal gland of cows that could induce skin lightening in common frogs.
Effective dose: It is the minimum dose or concentration of a drug that produces a biological response in 50% of a population being studied. Median lethal dose: For either drugs or toxins, it is a toxic unit that measures the minimum dose that causes death (lethal dose) in 50% of cases.

The melatonin receptors are G protein-coupled receptors and are expressed in various tissues of the body. There are two subtypes of the receptor in humans, melatonin receptor 1 (MT 1) and melatonin receptor 2 (MT 2). [2] Melatonin and melatonin receptor agonists, on market or in clinical trials, all bind to and activate both receptor types. [1]
