Melatonin in Man

Considerable advances in the understanding of melatonin in man are now possible. The advent of melatonin measurement has allowed previous conjectural possibilities for melatonin and pineal gland function in man to be tested. The impressive feature of melatonin physiology in the human is the stability of secretion, which fits with an enviromental sensing function of the pineal gland and with melatonin as having some coordinating role in human endocrinological function. The possibilities for the use of melatonin in human and veterinary clinical medicine is raised.
