Melatonin is a type of hormone secreted by pineal gland, a tiny structure located at the base of the brain which helps regulate other hormones and maintains the body's circadian rhythm. The circadian rhythm is what we normally refer to as our body clock which plays a critical role in determining when we fall asleep and when we wake up. Darkness triggers the production of melatonin while light restrains its activity. Exposure to too much light in the evening or too little light during the day can disrupt the body’s normal melatonin cycles.

Artificial Melatonin

Due to the advancement of science, artificially produced or pharmacy grade melatonin can be created by pharmacist to help people normalise their sleeping habits. This structure is molecularly identical to the melatonin of the human body without unwanted extras.

Benefits of Melatonin

Studies show that supplements can accelerate sleep and relieve jet lag without the danger or side effects associated with prescription sleeping pills.

Melatonin may also have many other benefits and has been reported to make people feel better, strengthen the immune system, and reduce free radicals in the body. Recent researches are also exploring the prospect of melatonin's effect as an anti-oxidant, immno-modulator in cancer, delayed sleep-phase disorders, and more.

Recommended Use

Based on existing studies and clinical tests, melatonin is generally regarded as safe in recommended doses for short-term use. However, children and pregnant or nursing women should not take melatonin dietary supplements without a seeking for a health professional's approval. Taking melatonin with alcohol and other drugs, for sufferers from autoimmune disorder, liver or kidney disease is not advisable either.

Side Effects

Side effects of any drug vary from person to person. In the case of melatonin, some common side effects may include changes in blood vessels that may affect blood flow, reduced sperm count, and lowering of the body's temperature (hypothermia). These side effects go away when you stop taking melatonin. Other reversible side effects may include stomach problems, headache, depression, morning grogginess, and vivid dreams. But unlike sleeping pills, melatonin does not have morning after-hangover wherein you feel heavy instead you normally wake up feeling refreshed and full of energy.

Reminder: While Melatonin is classified as supplement rather than prescription medicine, it’s still important that you consult your doctor to avoid any adverse effects on your body.
