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 is generally considered safe to take every night at doses between 0.5 mg and 5 mg. A safe starting dose of melatonin is between 1 mg and 5 mg for adults. More melatonin can cause side effects, particularly in older adults. For older adults, lower doses, such as 1 mg, are usually considered enough melatonin.
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.
Regardless of whether it truly helps with sleep or not, Dr. Ramkissoon doesn't recommend taking melatonin long-term.
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.
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.
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.
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.

Melatonin does tend to have less risky potential side effects than certain prescription sleep aids, Grandner says, but he adds that “melatonin is not a good alternative to prescription sleep medications. It does not work as a sedative and it is ineffective in most cases of insomnia.”
1. Cherries. Cherries (especially sour cherries like the Montmorency variety) are one of the only (and highest) natural food sources of melatonin. Studies have shown a boost in circulating melatonin after consumption of cherries, though sweet cherries have half the melatonin content as sour cherries.
Milk. A glass of warm milk is a well-known and common sleep remedy, and for good reason! Milk is one of the best dietary sources of melatonin. It also contains the amino acid tryptophan, which increases concentrations of melatonin and serotonin and helps you drift off to sleep easier.
Melatonin's target sites are both central and peripheral. Binding sites have been found in many areas of the brain, including the pars tuberalis and hypothalamus, but also in the cells of the immune system, gonads, kidney, and the cardiovascular system (39, 40).
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 is generally regarded as safe for seniors by physicians and pharmacists because its side effects are mild, it's not habit forming, and it does not cause withdrawal symptoms if you stop taking it suddenly.
