Melatonin is a hormone that regulates the body's circadian rhythm and promotes sleep. It is often taken as a supplement to improve sleep. Some research suggests that melatonin may also help manage blood sugar levels in people with type 2 diabetes. However, the effects of melatonin on diabetes are still being studied, and there are conflicting findings. While some studies indicate that melatonin may help reduce insulin resistance and improve glycemic control, others have found no significant impact on insulin sensitivity or blood glucose levels. As such, it is important for individuals, especially those with diabetes, to consult a healthcare professional before taking melatonin supplements to understand the potential benefits and risks.

What You'll Learn
Melatonin may help manage blood sugar in type 2 diabetics
Melatonin is a hormone that regulates the body's circadian rhythm, causing body functions to become more or less active at different times of the day. It also appears to play a role in glucose metabolism.
Some people take melatonin supplements to help them sleep. While melatonin has been shown to improve sleep maintenance in people with type 2 diabetes, its effects on blood sugar management are less clear. Some studies suggest that melatonin supplements may have benefits for managing blood sugar in type 2 diabetics, possibly by regulating insulin secretion. For example, a 2021 meta-analysis suggested that melatonin supplementation reduced fasting blood glucose levels, HbA1c, and insulin resistance in patients with type 2 diabetes. Another study found that melatonin supplementation at 10 mg/d had beneficial effects on glycemic control and insulin resistance in diabetic patients, while lower doses of 3–6 mg/d were not effective.
However, other studies have found no significant effects on blood glucose and lipid metabolism. A 2022 review of research on melatonin and glucose metabolism reported mixed results, and more research is needed to confirm the effects of melatonin on blood sugar management in type 2 diabetes.
It is important to note that individuals should seek medical advice before taking melatonin supplements, as researchers are still learning about its potential benefits and risks, as well as the optimal dosing and formulation for people with type 2 diabetes.

Melatonin supplements can help reduce inflammation and cholesterol
Melatonin is a hormone that regulates the body's circadian rhythm, which causes body functions to become more or less active at different times of the day. It is commonly used as a supplement to aid sleep. However, its role is multifaceted, and it has been shown to have anti-inflammatory effects through multiple mechanisms.
Melatonin has been shown to reduce macromolecular damage in all organs by scavenging free radicals. It also activates antioxidant defences such as superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase, glutathione reductase, and glucose-6-phosphate dehydrogenase. On a genetic level, melatonin prevents the upregulation of inflammatory cytokines, including interleukin (IL)-1, IL-6, and tumour necrosis factor (TNF). It also inhibits the production of adhesion molecules necessary for leukocyte adhesion to endothelial cells, thereby decreasing leukocyte migration and oedema, which is a key component of the innate inflammatory response.
Several studies have demonstrated the anti-inflammatory effects of melatonin. One study showed that melatonin had significant anti-inflammatory effects on interleukin (IL)-1, IL-6, IL-8, and tumour necrosis factor (TNF). Another study found that melatonin supplementation could reduce the progression of non-alcoholic fatty liver disease and might also improve hepatic function.
Melatonin supplements may help reduce inflammation, triglycerides, and total cholesterol levels. This may reduce the risk of certain health conditions that are more common in people with type 2 diabetes, such as heart disease. However, more research is needed to understand the potential benefits and risks of melatonin supplementation for managing type 2 diabetes, as well as the optimal dosing, formulation, and timing of supplementation.

Melatonin regulates the body's circadian rhythm
Melatonin is a hormone that regulates the body's circadian rhythm and promotes sleep. The body's central circadian clock, located in the suprachiasmatic nuclei (SCN) of the hypothalamus, tunes the innate circadian physiological rhythms to the ambient 24-hour light-dark cycle. The SCN-activated, light-inhibited production of melatonin conveys the message of darkness to the clock and induces night-time physiological functions, such as sleep. Melatonin is regulated by the circadian oscillator and acts as a darkness signal, providing feedback to the oscillator.
In humans and most diurnal mammals, melatonin is secreted at night with a robust circadian rhythm and maximum plasma levels occurring around 3 to 4 AM. The daily rise of melatonin secretion correlates with a subsequent increase in sleep propensity about two hours before the person's regular bedtime. The rhythmic release of melatonin is regulated by the central circadian rhythm generator—the suprachiasmatic nucleus (SCN) of the anterior hypothalamus.
Melatonin has been shown to have beneficial effects on natural sleep regulation, making it a good treatment option for insomnia, especially in the elderly or those with rebound insomnia, next-day effects, withdrawal, or elements of circadian rhythm sleep disorders. Melatonin treatment has been reported to be effective in treating disorders such as jet lag and delayed sleep phase syndrome. It also has a major role in regulating the body temperature rhythm.
Melatonin also has a role in psychiatric illness and the treatment of comorbid depressive disorders. Agomelatine, for example, promotes sleep at night with its melatonergic effects and alertness during the day with its serotonergic effects. Overall, melatonin's positive effects on the circadian clock functions and sleep-wake cycle may delay AD-related pathology.

Short-term melatonin use improves sleep maintenance in type 2 diabetics
Melatonin is a hormone that regulates the body's circadian rhythm, causing body functions to become more or less active at different times of the day. It also appears to play a role in glucose metabolism.
Some people take melatonin supplements to help them sleep. Short-term use of melatonin supplements has been found to improve sleep maintenance in people with type 2 diabetes and insomnia. A 2016 study found that sleep efficiency, wake time after sleep onset, and the number of awakenings improved significantly when taking prolonged-release melatonin compared to a placebo.
However, it is important to note that the effects of melatonin supplementation on diabetes are still being studied, and the results have been mixed. While some research suggests that melatonin supplements may have benefits for managing blood sugar in type 2 diabetes, other studies have not found these results. Genomic studies have also revealed that rare variants in the melatonin receptor 1b (MTNR1b) gene are associated with an increased risk of type 2 diabetes.
Individuals should seek medical advice before taking melatonin supplements as a healthcare professional can explain the potential benefits, risks, and drug interactions. More research is needed to understand the potential long-term risks and benefits of melatonin supplementation for managing type 2 diabetes, as well as the optimal dosing and formulation.
