Melatonin is a hormone that regulates some body functions, including the sleep/wake cycle. Some people take melatonin supplements (over the counter) for promoting sleep. Some studies suggest that melatonin may help improve blood pressure, glucose levels, blood lipid levels, which are components of "the metabolic syndrome." This trial seeks to compare the effects of melatonin supplementation versus placebo on these factors in patients with metabolic syndrome.

This is an 8-week randomized, double-blind, placebo-controlled, parallel, fixed-dose pilot clinical trial to test the effectiveness of melatonin treatment versus placebo on symptoms of Nig...
Background: Melatonin is a neurohormone that regulates the circadian rhythm by translating photoperiodic information from the eyes to the brain. Working hypothesis and aims: There is a po...
The aim of our study is to investigate the effects of a treatment with melatonin on clinical, endocrine and metabolic features in women affected by PCOS. The study group included 40 patien...
The purpose of this study is to evaluate the effects of oral melatonin plus zinc supplementation in relieving self-reported fatigue in CFS/ME
Sleep-Wake and behavioral disorders in Smith Magenis Syndrome (SMS) are strongly linked to an inversion of the nychtemeral secretion of melatonin. This inversion have been described in chi...
To evaluate the efficacy of melatonin compared to placebo in reducing pain associated with burning mouth syndrome (BMS), as well as side effects of treatment and effects on sleep quality, anxiety, and...
This investigation was designed to determine the effect of melatonin supplementation on mental health parameters, metabolic and genetic profiles in patients under methadone maintenance treatment (MMT)...
This systematic review and meta-analysis of randomized controlled trials (RCTs) was carried out to determine the effect of melatonin supplementation on the inflammatory markers among individuals with ...
It has been shown recently that metabolic syndrome is associated with gut dysbiosis. The gut microbiota may be the main target for prevention or treatment of metabolic syndrome. We investigated the ef...
In HIV-infected patients on combination antiretroviral therapy (cART), lipodystrophy shares many similarities with metabolic syndrome, but only metabolic syndrome has objective classification criteria...
A biogenic amine that is found in animals and plants. In mammals, melatonin is produced by the PINEAL GLAND. Its secretion increases in darkness and decreases during exposure to light. Melatonin is implicated in the regulation of SLEEP, mood, and REPRODUCTION. Melatonin is also an effective antioxidant.
A family of G-protein-coupled receptors that are specific for and mediate the effects of MELATONIN. Activation of melatonin receptors has been associated with decreased intracellular CYCLIC AMP and increased hydrolysis of PHOSPHOINOSITIDES.
A cluster of metabolic risk factors for CARDIOVASCULAR DISEASES and TYPE 2 DIABETES MELLITUS. The major components of metabolic syndrome X include excess ABDOMINAL FAT; atherogenic DYSLIPIDEMIA; HYPERTENSION; HYPERGLYCEMIA; INSULIN RESISTANCE; a proinflammatory state; and a prothrombotic (THROMBOSIS) state.
