Melatonin 10MG is a 10-milligram format of melatonin, an indoleamine hormone synthesized from tryptophan via serotonin. Researchers study melatonin for its potential role in circadian timing and sleep wake biology, as well as its broader signaling activity in neuroendocrine research. Studies have also examined melatonin in the context of oxidative stress pathways and seasonal physiology.
