Melatonin: A Potential Disease-Deferring Hormone (Psychology Today)

Melatonin, a hormone that regulates our body's circadian rhythms, is synthesized at night by the pineal gland. As a dietary supplement, it is not regulated ...

European Journal of Pharmacology 907: (article 174365, 13 pages), 2021. Modulation of the tumor microenvironment (TME) by melatonin. Frontiers in Pharmacology 13 (article 947117), 2022. International Journal of Molecular Sciences 23: 1238 (23 pages), 2022. In most countries, melatonin requires a prescription (Kuehn). Melatonin reportedly has a role in the treatment of osteoporosis (López-Muñoz et al., 2022). [circadian rhythms](https://www.psychologytoday.com/us/basics/circadian-rhythm), light is the strongest “timekeeper" (Walker et al.). It has raised safety concerns, especially with long-term use in certain populations like children and adolescents (Kuehn, July 2022). This pool, which does not exhibit a circadian rhythm, may be a "critical factor" in the optimal functioning of mitochondria (Reiter et al., 2022). Furthermore, it has major anti-cancer effects: it is oncostatic, namely—it can suppress cancer growth in some tumors and even suppress the development of metastases (Reiter et al., 2021a; Mu and Najafi, 2021). Furthermore, since animals in the wild experience some light from the moon or stars, creating an extremely dark environment may not mimic nature (Aulsebrook et al., 2022).
