Melatonin hormonu, son yıllarda tüm dünyada gittikçe artan bir ilgiyle araştırılmaktadır. Ana görevi vücudun biyolojik saatini koruyup ritmini ayarlamak olan melatonin, vücudun birçok biyolojik ve fizyolojik süreçlerinde yer alır. Hücrelerin yenilenmesi, bağışıklık siteminin güçlenmesi, uyku ritminin ve vücut ısısının düzenlenmesi diğer önemli görevleri arasındadır. Lipofilik özelliği nedeniyle bilinen en güçlü antioksidandır. Bu özelliği sayesinde tüm vücut alanlarına ulaşabilmekte ve kan-beyin bariyerini geçebilmektedir. Uyku problemi olan kişilerde melatoninin düşük düzeyde bulunması, ilaç olarak kullanımını akla getirmektedir. Yapılan uygulamaların ardından melatoninin uyku total süresini değiştirmeden uyku kalitesini artırdığı belirlenmiştir. Ancak yaygın araştırılmasına rağmen melatoninin işlevleri halen tamamıyla bilinmemektedir. Bu nedenle melatonin ile ilgili mevcut bilgilerin gözden geçirilmesi, bu alanda araştırma yapanlara rehberlik edecektir.

Nevertheless, despite high number of researches done, the functions of melatonin have not yet fully understood. Therefore, review of the available information related to melatonin will be guide for researchers in the field.
