If you’re looking, you’ll find that TikTok has a remedy for everything—from hair growth to Magnesium for sleep. For a while, I couldn’t open the app after 6 p.m. without seeing a “sleepy-girl mocktail” video.

Millions of (presumably well-rested) users are concocting a wind-down elixir said to improve relaxation and promote better sleep quality. If you’re crafting a mocktail to viral-post specs, set the vibe with a wine glass, ice, tart cherry juice, and magnesium powder. Partial to a fizzy drink? Top it off with a bit of seltzer or prebiotic soda (think Poppi or Olipop).

Mixing magnesium with tart cherry juice “increases support to melatonin production and muscle relaxation to support sleep,” notes functional medical nutritionist Leona West Fox, a member of the medical board at buzzy supplement brand Lemme. It can also decrease inflammation.

Offline, sleep savants are adding their own touches—or tinctures—to bedtime elixirs. “I start my wind-down routine at six or 6:30,” says Shizu Okusa, founder of herbal remedy brand Apothékary. “I know it sounds early but I like to have a ‘happy hour-slash-I survived the day’ mocktail—it’s like a pat on the back.”

Okusa’s particular quaff blends tart cherry juice with turmeric, half a teaspoon of Natural Vitality Calm magnesium glycinate, and three droppers full of Apothékary Wine Down—an herbal tincture formulated with L-theanine, California poppy, and blue Vervain. After some journaling, dinner, and a bath, “I start to doze off by 9:30 p.m.,” she says.

Sakara Life co-founder Danielle Duboise, a certified holistic health coach and nutritionist, pairs her nightly magnesium with a cup of tea. Sakara’s Sleep Superherb is concocted with catnip, valerian, and passionflower. She might mix in some Moon Juice Magnesi-Om—or have a square of chocolate on the side.

“I always recommend getting your nutrients from food first,” Duboise notes. “Some of my favorite magnesium-rich food sources are spinach, swiss chard, pumpkin seeds, almonds, black beans, avocado, bananas, and dark chocolate.”

A good sleep mask is a worthy pairing, too. “Magnesium combined with sleeping in complete darkness activates the body’s optimal natural melatonin production,” West Fox explains.

Does magnesium actually work?

“Magnesium is a natural mineral found in the body that plays a key role in the body’s energy production, cardiovascular system, and nervous system,” Shelby Harris, a licensed clinical psychologist specializing in behavioral sleep and director of sleep health with Sleepopolis, tells Vogue. While she notes that more research is needed to fully understand the relationship between sleep and magnesium, “[it] can help to relax the nervous system, leading to increased relaxation and reduced anxiety. This calming effect may help to promote quality sleep in the evening.”

Sleep benefits aside, certified sleep specialist and board-certified pediatrician Angela Holliday-Bell says that magnesium has many functions in the body. “It helps to regulate nerve function and muscle activity. It helps to stabilize blood pressure and aids in bone health and energy production,” she says.

Plus, it’s shown to improve your mood. “Not only does magnesium relax muscles and promote GABA, a neurotransmitter essential for creating calm in the brain and body, it also calms the nerves and the nervous system,” says West Fox. “In addition, it helps to reduce stress and regulate cortisol, our stress hormone, that if left unchecked can disturb sleep and a healthy circadian rhythm.”

What’s the difference between magnesium and melatonin?

“They’re both supportive in different ways,” explains Amanda Chantal Bacon, founder of Moon Juice—the brand behind the viral supplement Magnesi-Om. “While magnesium is a mineral that helps your mind and body relax for bed, melatonin is a hormone that signals to the brain when it’s time to sleep.” According to Dr. Holliday-Bell, someone might choose magnesium to naturally promote relaxation and recovery or if they are not getting a sufficient amount of magnesium from their diet.

Magnesium and melatonin also play nicely together. When used in tandem, they provide “synergistic action for improved sleep onset, reduced insomnia symptoms, and a more structured sleep pattern,” says West Fox, noting that Lemme Sleep Gummies are formulated with both.

What to consider when buying magnesium for sleep

The kind of magnesium you take does make a difference. “Some common types of magnesium supplements include magnesium oxide, citrate, glycinate, L-threonate, and malate,” says Dr. Harris. “Magnesium glycinate is typically the best option for sleep since it’s highly absorbable and gentle on the stomach.” She continues that glycine boasts calming and relaxing properties, making it good for sleep. Bacon’s Magnesi-Om, however, takes a different approach: “We chose gluconate, acetyl taurinate, and citrate because they’re easy for the body to absorb and holistically support muscle relaxation, cognitive function, and regularity. Plus, we added L-Theanine, a nootropic amino acid, to promote alpha waves in the brain for calm.”

My experience with the sleepy-girl mocktail

I’ve long been on the quest to improve my sleep quality, so when I stumbled upon the sleepy-girl mocktail, I ran to the grocery store almost immediately. Making the concoction is simple enough—I opted for the Moon Juice Magnesi-Om and simply mixed it in. I love a little luxurious moment to myself before bed, so I quite enjoyed the ritualistic feel of this, almost like a bedtime treat.

Did it work? As Dr. Holliday-Bell describes, this is not a “magic bullet”—meaning it’s not going to put you right to sleep. However, I did start to feel more relaxed almost immediately, even before I finished my entire glass. Instead of indulging in a few more Gossip Girl episodes, I felt ready to actually close my eyes and go to sleep. Come morning, I certainly felt well rested. Wanting to get someone else’s feedback, I asked my friend Jada to try. Fifty minutes after drinking the mocktail, she texted me, “Relaxed, sleepy, and ready for bed.” The following day she told me she “slept like a baby.” Score.

How do I use magnesium?

Interested in trying magnesium yourself? First, we’d recommend getting the green light from your doctor, as you would with any other supplement. Generally speaking, always follow the advised dosage of your chosen supplement to avoid taking too much. “I would recommend incorporating magnesium glycinate into your bedtime routine by taking the RDA (recommended daily allowance, of about 400 to 420 mg for adult men and 310 to 320 mg for women) about an hour before bedtime,” says Dr. Holliday-Bell.

Casie Giroux, clinical herbalist at Apothékary, advocates upping magnesium intake (within one’s RDA, of course) to accommodate a particular season of life. “During times of high stress, you can further deplete mineral levels in the body, so I recommend increasing magnesium intake,” she says. “Also, if you are working out more than usual it can help support recovery and muscle aches.”

Gender may also come into play. “Women and men may have slightly different magnesium needs,” suggests Duboise. “Generally, women tend to require slightly more magnesium than men due to biological factors. For example, “Menstrual bleeding can lead to a loss of blood, and along with it, a loss of essential minerals including magnesium.” She adds that magnesium typically decreases with estrogen, so people in menopause may want to up their intake as well.
