The Effect of Melatonin Supplement on High Arterial Blood Pressure: An Overview from Clinicaltrials.gov

Abstract

Background Melatonin is a hormone produced by the pineal gland primarily at night. It has been suggested that melatonin may possess various cardiovascular benefits, including the potential to lower blood pressure. For this reason, we sought to identify and provide evidence of the effectiveness of melatonin on high arterial blood pressure in clinical trials. Methods Using the search term “melatonin and hypertension”, a search of the ClinicalTrials.gov database was performed on October 10 th , 2023. I defined the exclusion and inclusion criteria to isolate appropriate clinical trials. Inclusion criteria for the search included hypertension that utilized melatonin as a treatment supplement; all non-related trials were omitted from the search. The data extractions, including study title, study type, study status, and intervention and outcome details, were compiled. Results Of the 13 clinical trials identified, only three focused on examining the effects of melatonin. The study titles, enrollment numbers, conditions, statuses, interventions, and outcome measures have been explained in depth. Information gathered from these clinical trials will assist us in identifying the possible risks and benefits of melatonin with respect to high arterial blood pressure. Conclusion Melatonin has been shown to be an effective treatment for lowering blood pressure. More research is required to fully establish the potential benefits and risks and highlight the mechanisms through which melatonin may influence blood pressure regulation.
