Is taking melatonin addictive?

No, melatonin isn’t addictive. Even if you take it for a longer time, it doesn’t cause dependence.

Can I use Melatonin Sleep Spray every day?

Yes. For most healthy people, daily use is safe. But if you’re taking it long-term, it’s a good idea to talk to a doctor, because for most people it’s enough to use melatonin only when they really have trouble sleeping.

Does supplementing melatonin reduce your body’s own melatonin production?

No. Current scientific evidence agrees that typical doses of melatonin do not reduce your body’s own melatonin production.

Will it also help with changing time zones?

Yes. Melatonin can help reset your internal clock to the new time more quickly and improve sleep quality faster.

Which medications should melatonin not be combined with?

You should be cautious if you’re taking blood thinners, certain antidepressants, immunosuppressants, anti-seizure medications, or diabetes medication.

Melatonin can affect how these medications work. If you take any of these, always consult your doctor before supplementing.
