Melatonin, the hormone produced by the pineal gland, has been the matter of unsubstantiated, exaggerated claims during current years.
A veritable melatonin mania in the media and injudicious advertising has clouded the actual extraordinary role this hormone is known to play. On the other hand, there is an entire area of research related to its antioxidant, free radical scavenging properties.
Some, but not all researches of melatonin functions in major depression show low nocturnal secretion. Some, but not all SAD patients have a held-up melatonin phase, whereas lots of patients with non-seasonal depression have an earlier phase.
Some, but not all anti depression medicines improve melatonin levels. The dosage for managing melatonin depression for patients is therefore rather not clear.
