What is Melatonin?

Melatonin is a hormone which may be used to treat jet lag in travellers crossing several time zones. Melatonin occurs naturally in the human body and is involved in regulating our sleep-wake cycle.

How does Melatonin work?

Normally, levels of melatonin increase when it gets dark outside, making you feel sleepy and tired to prepare your body for rest. When you travel to a place with a different time zone, your body clock takes some time to adjust to the change in time. Taking Melatonin can help you to sleep when it is nighttime at your destination and overcome the time zone gap.

How do I use Melatonin?

One tablet of Melatonin 3mg should be taken at your usual bedtime when you arrive at your destination, for no longer than 5 days. For frequent fliers, treatment may be taken for a maximum of 16 treatment periods per year.

How long does it take for Melatonin tablets to work?

Once taken, Melatonin tablets start working quickly to help you get to sleep more easily and overcome the time zone gap. Melatonin helps to speed up the process of your internal body clock adjusting to the new time zone while also minimising symptoms of jet lag.

Where can I buy Melatonin in the UK?

You can buy Melatonin 3mg from Pharmica by completing a short consultation. Melatonin tablets cannot be purchased over the counter and require a prescription. Following completion of your online medical consultation, you can get same-day or next-day delivery to ensure your treatment arrives promptly ahead of travel.

"Sleep"

Product Review:

Melatonin has been helpful for improving my sleep routine, especially when I struggle to fall asleep. It helps me feel naturally drowsy rather than knocked out, and I tend to fall asleep faster and wake up feeling more refreshed. It’s particularly useful for disrupted sleep schedules or periods of stress.

That said, the effects can vary from person to person. On some nights it works better than others, and taking too high a dose can cause grogginess or vivid dreams. It’s best used occasionally rather than every night.

Overall, a good option for short-term sleep support when used responsibly and at a low dose.

Service Review:

Good service. The process was straightforward and timely
