Natural alternatives to melatonin, such as magnesium, valerian root, l-theanine, chamomile, and passionflower, are all-natural remedies that have been used for centuries to promote relaxation and help people get a better night's sleep.
Generally safe
Your body likely produces enough melatonin for its general needs. However, evidence suggests that melatonin supplements promote sleep and are safe for short-term use. Melatonin can be used to treat delayed sleep phase and circadian rhythm sleep disorders in the blind and provide some insomnia relief.
Melatonin can cause adverse effects at higher doses, but it is unlikely to cause a lethal overdose. In adults, higher doses may cause uncomfortable side effects such as headache and nausea. Melatonin overdose in children is a growing concern with increasing hospitalizations.
Melatonin: Melatonin is considered one of the safest over-the-counter sleep aids, with few side effects. A prescription drug called ramelteon is designed to mimic the effects of melatonin. Like melatonin, it is not considered habit-forming and it does not affect balance.
Antihistamine sleep-aids (like doxylamine succinate and diphenhydramine) are largely considered to be “non-habit-forming,” because they do not cause physical dependence.
Regardless of whether it truly helps with sleep or not, Dr. Ramkissoon doesn't recommend taking melatonin long-term.
- In the UK, the Medicines Control Agency has banned the high-street sale of melatonin after it was decided the compound was "medicinal by function," and as such requires a drug license. The MCA has written to all relevant suppliers, which comprise mainly health food shops, ordering them to stop selling the product.
Taking an unknown dose of serotonin for a long time can affect your heart, blood vessels, and brain. People taking medication for a mood disorder should be especially careful, as these medications already boost serotonin so an extra dose of serotonin can particularly impact them.
Magnesium is best for those with magnesium deficiency, insomnia due to stress or anxiety, or muscle pain and cramping. On the other hand, melatonin is considered best for those who suffer from circadian rhythm disruption, hormonal imbalances, or melatonin deficiency.
A warm bath or a massage before bedtime can help prepare you for sleep. Create a relaxing bedtime ritual, such as taking a hot bath, reading, soft music, breathing exercises, yoga or prayer. Avoid trying too hard to sleep. The harder you try, the more awake you'll become.
Furthermore melatonin has been shown to have valuable effects on cardiovascular health, blood pressure, and endothelial function and it might benefit patients with heart failure.
Do not use melatonin if you are pregnant or breastfeeding or have an autoimmune disorder, a seizure disorder or depression. Talk to your health care provider if you have diabetes or high blood pressure.
Eggs and fish are higher melatonin-containing food groups in animal foods, whereas in plant foods, nuts are with the highest content of melatonin. Some kinds of mushrooms, cereals and germinated legumes or seeds are also good dietary sources of melatonin.
In several clinical trials, melatonin was found to be well tolerated and not associated with serum enzyme elevations or evidence of liver injury. Despite wide scale use, melatonin has not been convincingly linked to instances of clinically apparent liver injury.
Melatonin levels decline gradually over the life-span and may be related to lowered sleep efficacy, very often associated with advancing age, as well as to deterioration of many circadian rhythms. Melatonin exhibits immunomodulatory properties, and a remodeling of immune system function is an integral part of aging.
The NDPSC considered that insufficient information was available on the safety of melatonin to allow it to remain exempt from scheduling for human therapeutic use and that it should not be available without prescription.
In the UK and most of Europe, it's classed as a medicine, not a health supplement and as such, requires a prescription. This is because melatonin is considered “medical by function” which means that it requires a drug licence.
Melatonin pills are available in Australia. Currently, you need a prescription from your doctor for melatonin. From June 2021, a form of melatonin will be available from pharmacies without a prescription for people aged over 55. There are 2 ways to use melatonin pills.
