Proven Health Benefits

 

Enhances Sleep Quality

Many high-quality studies support the key benefit of melatonin:

- Research shows that melatonin effectively treats sleep disorders.
- Studies highlight its significant role in regulating circadian rhythms and related conditions.
- In individuals with primary sleep disorders, melatonin has been found to improve sleep quality and may assist with insomnia.
- Reviews confirm the effectiveness of melatonin for sleep issues without major side effects.
- Research indicates that melatonin effectively reduces sleep onset, alleviates delayed sleep phase syndrome, and helps regulate sleep patterns in blind individuals.
- For those who are blind or work night shifts, melatonin has been shown to help resynchronize circadian rhythms.
- Studies reveal that melatonin treatment leads to positive sleep outcomes.
- In children with severe chronic sleep disorders, oral melatonin has improved sleep patterns.

Lowers Risk of Cardiovascular Disease

 

Research indicates that melatonin can help protect against heart disease:

​

- Studies suggest that melatonin may aid in treating heart disease linked to heart muscle injury and insufficient blood supply.
- Low levels of melatonin have been associated with an increased risk of heart complications.
- In patients with cardiovascular conditions, low melatonin levels were observed in those with coronary artery disease, hypertension, and congestive heart failure.
- Administration of melatonin in heart failure patients has been shown to reverse some pathological processes associated with the condition.
- Both rodent and human studies demonstrate that melatonin’s cardioprotective and antioxidant properties can reduce the incidence of heart failure, damage, and abnormal heart functions.

​

Prevents Cancer

 

Evidence suggests that melatonin possesses anti-cancer properties:

​

- Research shows that melatonin administration can inhibit the development, progression, and spread of cancer cells.
- In studies involving rats and human tumor cells, melatonin exhibited anti-cancer effects.
- Cancer patients receiving melatonin showed improved regression of tumors, increased survival rates, and better tolerance to chemotherapy.
- In patients with tumors, melatonin significantly reduced overall survival rates of the tumors.
- A review of studies found that melatonin enhanced the effectiveness of chemotherapy while minimizing side effects.

 

Promotes Weight Loss

 

Melatonin has also shown benefits for overweight and obese individuals:

​

- In obese patients on calorie-restricted diets, melatonin supplementation led to weight loss.
- Postmenopausal women experienced weight reduction with melatonin administration.
- A review suggested that melatonin supplementation was particularly effective for weight loss in children and adolescents.
- In mice fed a high-fat diet, melatonin inhibited weight gain and mitigated obesity-related metabolic and inflammatory issues.
- In zebrafish models, melatonin treatment resulted in weight loss and regulation of weight gain.

 

Boosts Immunity

 

Melatonin may strengthen the immune system:

 

- Research indicates that melatonin can play a therapeutic role in enhancing immune functions, especially in individuals with declining immunity.
- A review of studies suggests that melatonin acts as an effective immunostimulant, providing an early immune response against viruses and parasites.
- Melatonin's anti-inflammatory and immunomodulatory effects may aid in treating influenza.
- Some studies propose melatonin as a potential treatment for COVID-19.
- In mice on a high-fat diet, oral melatonin supplementation protected against metabolic and inflammatory disorders.

 

Lowers Blood Pressure

 

Melatonin may have anti-hypertensive effects:

​

- Reviews suggest that melatonin effectively regulates blood pressure.
- In patients with nocturnal hypertension, melatonin taken before bedtime significantly reduced systolic blood pressure.
- Controlled-release melatonin was found to be safe and effective in treating nocturnal hypertension.
- In diabetic patients with essential hypertension, melatonin treatment helped restore normal blood pressure levels.
- Both human and animal studies consistently demonstrate melatonin's nocturnal blood pressure-lowering effects.

​

Boosts Brain Performance

 

Evidence supports the positive effects of melatonin on brain health:

​

- In older adults, nightly melatonin administration has been effective in addressing age-related cognitive decline.
- Higher physiological levels of melatonin in elderly patients are linked to a lower occurrence of cognitive impairments and mood disorders.
- In elderly individuals with mild cognitive impairment, immediate-release melatonin administration safely improved certain aspects of memory without side effects.
- Significant improvements in symptoms of Alzheimer’s disease were observed in patients receiving oral melatonin.
