Melatonin is a natural hormone produced by the human body that primarily regulates the sleep-wake cycle. It is secreted by the pineal gland located in the brain and becomes more active in darkness. Exposure to daylight lowers melatonin levels, keeping the body awake and alert. As night approaches, melatonin production increases, signaling the body that it’s time to rest. For this reason, melatonin is often called the “sleep hormone.” However, its role goes far beyond just sleep. Melatonin also helps strengthen the immune system, prevent oxidative stress in cells, and regulate body temperature.
The best-known function of melatonin is regulating the circadian rhythm, which controls the body’s 24-hour biological cycle — including sleeping, waking, eating, and hormonal activities. Maintaining balanced melatonin levels ensures that these bodily functions operate properly.
In addition, melatonin plays an important role in:
Strengthening the immune system
Protecting cells from oxidative stress (antioxidant effect)
Maintaining hormonal balance
Providing anti-inflammatory benefits
Over time, the use of melatonin supplements has expanded beyond treating sleep issues. Today, many people use it to enhance their overall well-being. Scientifically proven benefits include:
Helps fight insomnia: Melatonin is considered a natural aid for people who have trouble falling asleep.
Reduces jet lag: It helps the body adjust to new time zones during long-distance travel.
Relieves stress and anxiety: Some users experience calming and relaxing effects from melatonin.
Supports eye health: Studies show that melatonin protects retinal cells from oxidative stress.
Acts as a powerful antioxidant: It prevents cellular damage and may slow the aging process.
If your body doesn’t produce enough melatonin naturally or your lifestyle disrupts its production, melatonin supplements can help. These are available in pharmacies as tablets, capsules, or drops. The usual recommended dose is 1–5 mg, taken 30–60 minutes before bedtime.
Melatonin supplements are especially beneficial for:
People working night shifts
Frequent travelers
Individuals with chronic sleep disorders
Although melatonin is generally considered safe, it’s important to use it responsibly. Common side effects may include headache, nausea, drowsiness, and constipation. Some users may feel sleepy or distracted during the day.
Pregnant or breastfeeding women, people undergoing hormone therapy, or those with chronic illnesses should consult a doctor before using melatonin supplements.
Not all melatonin products on the market are of equal quality. To choose a reliable and effective supplement, pay attention to:
Certified products: Should be clinically tested for purity and dosage accuracy.
Natural ingredients: Prefer GMO-free options without colorants or preservatives.
Brand reputation: Choose trusted brands with positive customer reviews.
Clean formula: Avoid supplements containing additional hormones or stimulants.
Melatonin is not just a sleep aid — it’s a key hormone that supports your body’s natural rhythm, healthy sleep, and overall well-being. When used correctly and in harmony with your lifestyle, melatonin supplements can help improve your quality of life safely and effectively.
