This is the drink that went viral and then, unusually, stayed. Tart cherry juice, a scoop of magnesium powder, sparkling water over ice. That’s the whole recipe. Two minutes to make, tastes like a fizzy cherry soda, and it is genuinely pleasant to drink, which is more than most bedtime remedies can say for themselves.

The Science Behind It

The “sleepy girl mocktail” blew up on TikTok in late 2023 and has not slowed down since. Most viral drinks fade inside a season. This one stayed, and the reason is worth naming plainly: it tastes good, it takes two minutes, and it gives people a small deliberate ritual at the end of the day.

Tart cherry juice is one of the small handful of foods that contains melatonin at all, which is the reason it ended up in a bedtime drink rather than a breakfast one. That is a statement about what is in the fruit, and I am going to leave it there rather than telling you what it will do to your night. What I can tell you is that tart cherry is sour in a way sweet cherry is not, closer to a good sour cherry pie filling than to a bag of summer cherries, and it makes a far better mixer for it.

The cherry variety matters, mostly for flavor. Montmorency is the classic American sour cherry and it is what this drink is built around. Look for 100% Montmorency tart cherry juice, not cherry cocktail blends, which are usually apple juice wearing a red label.

Magnesium is the other half of the drink, and it is the half that is a supplement rather than a food. Be clear-eyed about that: this is not a herb out of a garden, it is a powder out of a tub, and how much of it you take is a question for a label and for whoever looks after your health, not for a recipe page. Glycinate is the form most people choose for an evening drink, and the practical reason is that it is the gentlest on the stomach.

Magnesium citrate also works and dissolves more easily, but it can have a laxative effect at higher doses. Glycinate is gentler on the gut.

The deep red color comes from anthocyanins in the cherries, the same class of antioxidants found in blueberries and butterfly pea flowers.

What You Will Need

  • 1/2 cup (4 oz) tart cherry juice, 100% juice
  • 1 scoop magnesium glycinate powder (use the scoop your brand supplies)
  • 4 to 6 oz sparkling water
  • Ice cubes
  • Optional: 1 tablespoon lavender simple syrup
  • Optional: squeeze of fresh lemon

On the cherry juice: Montmorency is the variety this drink is built on, and it is worth getting the right one. Brands like R.W. Knudsen and Cheribundi sell 100% tart cherry juice. Avoid blends that mix apple or grape juice for sweetness. The bottle should say “100% tart cherry juice” or “Montmorency cherry juice concentrate.”

On the magnesium: Natural Calm is the most popular brand for this drink and uses magnesium citrate. Calm gummies also work, though the powder is what dissolves into the glass and keeps this a drink rather than a drink plus a chew. If you prefer glycinate, which is gentler on the stomach, look for Pure Encapsulations or Doctor’s Best. Follow the scoop on your own tub rather than a number from a website, and start at the low end of it.

On the sparkling water: Optional. Some people prefer this as a still drink, which is fine. The sparkling water just makes it feel more like a cocktail. Topo Chico or any plain seltzer works.

How to Make It

  1. Pour 1/2 cup of tart cherry juice into a tall glass.

  2. Add one scoop of magnesium powder. Stir until completely dissolved. Magnesium citrate (Natural Calm) will fizz slightly when it dissolves. Glycinate dissolves quietly.

  3. Fill the glass about two-thirds with ice cubes.

  4. Top with 4 to 6 oz of cold sparkling water. Give it one gentle stir. Over-stirring kills the carbonation.

  5. If you want more complexity, add a tablespoon of lavender simple syrup. The floral note pairs naturally with the tartness of the cherry and the calming effect of lavender is its own sleep bonus.

  6. Drink it in the last half hour or so before bed. This is not a drink you slam at midnight standing at the fridge. Half the point of it is sitting down with something while the day closes.

Variations

Chamomile cherry sleep mocktail: Brew a strong cup of chamomile tea (2 bags, steep 10 minutes), let it cool, and use 3 oz of chamomile tea plus 3 oz of tart cherry juice as your base. Chamomile is the classic bedtime flower, and it tastes of apples and hay, which softens the sourness of the cherry considerably. We have a full breakdown in our chamomile health benefits guide.

Lavender cherry mocktail: Add 1 tablespoon of lavender simple syrup and skip the sparkling water. Serve over ice with still water. More of a sipper, less of a fizzy drink. Lavender aromatherapy has its own body of sleep research, and you get some of that from drinking it.

Tart cherry magnesium shot: For people who want it over with rather than drawn out. Combine 2 oz tart cherry juice, 1 scoop magnesium powder, and a squeeze of lemon. Stir and drink it straight. Done in 30 seconds.

Sleepy mocktail with ashwagandha: Add 1/2 teaspoon of ashwagandha powder (KSM-66 extract) to the base before adding sparkling water. Ashwagandha is an adaptogen with published evidence for reducing cortisol and improving sleep quality. Our ashwagandha drink recipe covers the dosing and research.

Before You Start

This is not a sleep cure. If you have chronic insomnia, talk to a doctor. It is a nice glass of something at the end of a day, and it is not a substitute for medical treatment.

Magnesium is a supplement, so treat it like one. If you take any prescription medication, ask your pharmacist before you start taking magnesium every night. That is a thirty second conversation at a counter and it is genuinely the right place for that question.

Tart cherry juice has sugar in it. It is fruit juice, and unsweetened 100% juice is still juice. If you are watching sugar, use 1/4 cup of cherry juice and 2 oz of water to dilute, and lean harder on the sparkling water to keep the glass full.

Start at the bottom of your tub’s scoop if you have never taken magnesium before. Some people are sensitive to it, especially magnesium citrate, which is famously unkind to a gut that was not expecting it. Glycinate is the gentler starting point.

How It Connects to Other Sleep Drinks

We have several drinks on this site designed around sleep and relaxation. Our herbal tea recipe for sleep uses valerian root, passionflower, and chamomile in a hot blend. The cortisol lowering tea targets stress hormones specifically. The lucid dream tea goes in a different direction entirely, aimed at dream vividness rather than depth of sleep.

This mocktail fills a different niche than those teas. It is cold, fizzy, takes 2 minutes, and does not require steeping anything. For people who want a bedtime ritual that feels more like a cocktail than a cup of tea, this is the one.

Common Questions

Does the sleepy time mocktail actually help you sleep?

Here is my honest answer. Plenty of people say it does, the anecdotal reports are overwhelming, and there is a whole internet of them. There is also no version of this drink that has been tested as a drink, and the two ingredients in it are doing very different kinds of work: one is a fruit juice, the other is a supplement. On top of both sits a half hour of sitting down with a nice glass and no screen, which is the single most obvious thing in the recipe and the one nobody credits. Try it and see what your own nights tell you.

Can kids drink this?

Tart cherry juice is juice, and juice is juice. The magnesium is a different matter entirely, and giving a supplement to a child is a conversation with a pediatrician, not something a recipe page should be scaling down for you. I am not going to publish a number here. Ask the person who looks after your kid.

When should I drink it?

In the last half hour before you plan to fall asleep, and ideally sitting down rather than on the way past the kitchen. Most people who keep this habit end up drinking it at the point in the evening where the screens go off, which is probably not a coincidence.

Is this the same as the “sleepy girl mocktail” from TikTok?

Same drink, different name. The viral version typically uses tart cherry juice, a scoop of Calm magnesium powder, and a splash of sparkling water or lemon-lime soda. We skip the soda, which is a lot of sugar right before bed, and use plain sparkling water instead. It is the same drink and it tastes cleaner.
