Melatonin

What is it?

Melatonin is a naturally occurring hormone primarily associated with the regulation of circadian rhythms and biological timing mechanisms. In laboratory settings, it is widely studied for its interactions with melatonin receptors (MT1 and MT2) and its role in sleep-wake cycle regulation, neuroendocrine signalling, and cellular responses to environmental light-dark patterns. Melatonin is supplied as a lyophilized powder for research investigating chronobiology, receptor pharmacology, oxidative stress pathways, and neurobiological signalling processes in controlled experimental models. Supplied as: Lyophilized powder Purity: 98–99%+ (HPLC verified) Storage: Store desiccated at -20°C for long-term. Short-term room temperature exposure (around 1 month) during shipping/handling is generally acceptable if kept sealed, dry, and protected from heat/light. Designation: FOR RESEARCH USE ONLY. Not intended for human or animal consumption.
