Exogenous melatonin is often used to address sleep disorders and other physiological conditions. However, the appropriate dosage and its effects on both humans and plants have been subjects of extensive research. This synthesis aims to evaluate whether exogenous melatonin is too much, based on the provided research data.
Effectiveness in Improving Sleep in Humans:
Dosage Considerations:
Effects on Plants:
Exogenous melatonin appears to be effective in improving sleep parameters in humans, particularly in reducing sleep onset latency and increasing total sleep duration. However, the subjective well-being effects are mixed, and the appropriate dosage may vary. In plants, low concentrations of melatonin are beneficial, but higher concentrations can be detrimental. Therefore, while exogenous melatonin can be beneficial, the dosage is crucial, and higher amounts may not always yield better results.
