The sleepy girl mocktail went from a viral bedtime drink to a genuine wind-down ritual for a lot of people. Here is the UK version, an honest look at whether it works, and a simple way to upgrade it.
Quick answer: A sleepy girl mocktail is tart cherry juice mixed with magnesium and topped with sparkling water, sipped before bed. Tart cherry naturally contains a little melatonin and magnesium is associated with relaxation, so the combination makes a calming evening ritual — though it is a nice habit, not a sleeping pill.
General information, not medical advice.
In this guide
What is in a sleepy girl mocktail?
Three things: pure tart cherry juice (the Montmorency kind, not sweetened cherryade), a serving of magnesium glycinate, and sparkling water to lengthen it. That is the whole idea — two ingredients associated with relaxation and sleep, in a glass that feels like a treat instead of a supplement.
The recipe
Sleepy girl mocktail (serves 1)
You will need:
- 120ml (about half a cup) pure tart cherry juice
- 1 serving magnesium glycinate powder (follow the label)
- Sparkling water, to top
- Ice, and a squeeze of lime (optional)
Method:
- Add the tart cherry juice to a glass with ice.
- Stir in the magnesium powder until fully dissolved.
- Top with sparkling water and add a squeeze of lime.
- Sip slowly, ideally 30 to 60 minutes before bed.
Does it actually work?
It is not magic, but the ingredients are not random either. Tart cherry naturally contains a small amount of melatonin and has been studied for sleep, and magnesium is involved in relaxation and the wind-down process. Just as important is the ritual: a consistent, alcohol-free cue that tells your body the day is done. For a deeper look at the magnesium side, see our guide to magnesium for sleep.
The Evopure upgrade
Two easy swaps make it work harder. Use a proper magnesium glycinate complex instead of a generic powder so you know the form and dose, and if you like, add a few drops of Cherry CBD Oil to lean into the flavour and your evening wind-down. Keep any CBD to the FSA's guidance of no more than 10mg a day, and check with your GP first if you take other medication.

What is a sleepy girl mocktail?
It is a bedtime drink made from pure tart cherry juice and magnesium, topped with sparkling water. It became popular as a calming, alcohol-free evening ritual.
Does the sleepy girl mocktail actually work?
Tart cherry contains a little natural melatonin and magnesium is associated with relaxation, so the combination makes a sensible wind-down ritual. It is a supportive habit rather than a sleeping pill, and consistency matters most.
What magnesium is best for a sleepy girl mocktail?
Magnesium glycinate is the usual choice because it is gentle on the stomach and associated with sleep and relaxation. Using a proper complex means you know the form and the dose rather than guessing.
Can I make it without magnesium powder?
Yes. You can take your magnesium separately and enjoy the tart cherry and sparkling water as the drink, or simply use tart cherry juice on its own. The ritual still works.
When should I drink it?
Most people have it around 30 to 60 minutes before bed as part of a wind-down routine. Keep magnesium a couple of hours away from any other medicines.
