Do Sleep Gummies Work? What's Actually Inside Them (and What May Be Better)

Sleep gummies are easily one of the most enticing sleep aids out there. They’re easy to find, come in plenty of formulations, and often taste like candy. But while some people may find that sleep gummies help them fall asleep faster, many of these sleep aids are far from the perfect solution, especially for midlife women.

During the menopause transition, hormone fluctuations can contribute to sleep problems, like middle-of-the-night wake-ups from hot flashes and night sweats. (Even the most popular melatonin gummies won’t make hot flashes go away.)

Plus, the market is packed with options, and research on many of the ingredients in gummies for sleep is still limited—and whether they’re safe to take every night depends on what’s in them. 

Still interested? Keep reading, because we’re going over everything you need to know about sleep gummies, including the active ingredients, what research says about them, and how they may help midlife women. If you’re still not sure about the best sleep solutions for you, a Midi clinician can help you figure out what’s disrupting your rest and what to try when you need more than a sleep gummy. 

What’s Usually in a Sleep Gummy?

All sleep gummies are definitely not created equal. These popular over-the-counter (OTC) supplements can be made with a wide variety of ingredients, depending on the brand. Some of the active ingredients commonly found in sleep gummies include:

• melatonin 
• magnesium glycinate
• amino acids like L-theanine and glycine
• botanicals or adaptogens like ashwagandha 
• CBD 

Sleep gummies may also contain inactive ingredients that aren’t necessary for better sleep—think added sugars or sugar alcohols, gelatin or pectin, and colors or flavorings. It’s worth checking the full ingredient list, especially if you have a metabolic health concern like diabetes or prediabetes and need to keep an eye on added sugar.

Does Melatonin Actually Work?

The short answer: Yes, melatonin can help you fall asleep—but it may work better for some sleep concerns than others.

Your brain naturally produces melatonin, a hormone that helps regulate your circadian rhythm, or sleep-wake cycle. Rather than simply sedating you, melatonin signals to your body that it’s time to sleep.

Since sleep gummies are dietary supplements, the FDA doesn’t evaluate them for safety and effectiveness. Melatonin gummies and other supplements use a synthetic form of the hormone, which may improve sleep. Studies show that melatonin can help with jet lag and make it easier to fall asleep when your sleep-wake cycle is disrupted.

But results may vary depending on the sleep issue. A 2024 review found that melatonin helped people fall asleep faster and sleep a little longer. A different review of people with sleep problems linked to other health conditions found that melatonin helped them fall asleep faster but didn’t significantly increase how long they slept.

Things can get a little confusing when it comes to the right dose. Because melatonin supplements aren’t FDA approved, there’s no standard dose or established upper limit. Studies have used anywhere from 0.1 to 10 milligrams (mg), but you’ll find many OTC melatonin supplements in doses around 1 to 5 mg.

And more isn’t always better. Melatonin may not be dose-dependent, so higher doses won’t automatically help you fall asleep faster or sleep better. In fact, research suggests that doses as low as 0.3 mg can be effective, while high doses may be more likely to leave you feeling groggy the next day. 

The timing is important, too. Melatonin may work best when you take it a few hours before bed, so it has time to kick in. 

For midlife women, there’s one more thing to keep in mind: Melatonin may help you fall asleep, but it won’t necessarily address what’s causing you to wake up during the night.

The Other Ingredients: What the Evidence Supports

Melatonin is easily one of the most popular sleep supplements, but it’s not the only one worth looking into. For example, Midi’s melatonin-free Nightly Steady Sleep+ combines ingredients that have been studied for sleep, including magnesium glycinate, zinc, glycine, and myo-inositol, in a formula designed to support falling asleep and staying asleep.

Here are a few ingredients that you might notice on a sleep gummy label:

L-theanine 

An amino acid found in tea leaves, L-theanine helps promote calm and relaxation by increasing alpha-wave activity in the brain. It may also improve sleep quality, particularly if stress or anxiety is keeping you up at night. In one clinical trial, people who took L-theanine reported falling asleep faster, experiencing fewer sleep disturbances, and having less stress and anxiety. Taking 200 to 400 mg of L-theanine per day may help calm your mind when it's time to wind down for the night.

Magnesium glycinate

Magnesium glycinate is a combination of the essential mineral magnesium with the amino acid glycine. Magnesium helps calm the nervous system and regulate neurotransmitters involved in sleep and relaxation, which may make it easier to quiet racing thoughts and fall asleep. The research behind this popular sleep supplement is promising. One study found that magnesium glycinate improved insomnia symptoms in adults. 

The glycinate form is also gentler on your digestive system than some other forms of magnesium, so it may be less likely to cause side effects like diarrhea. A typical low dose is around 140 to 250 mg, taken 30 to 60 minutes before bed.

Glycine

You can find it paired with magnesium, but glycine could have some sleep benefits of its own. This amino acid may help improve sleep quality by lowering your core body temperature, which naturally drops as your body prepares for sleep. An animal study suggests glycine may also boost serotonin, a neurotransmitter involved in regulating sleep, but more research is needed to see if it has the same effect in people. These effects could help reinforce your body’s natural signals that it’s time to hit the hay, but more research is needed.

A typical glycine dose is 3,000 mg (3 grams) taken 30 to 60 minutes before bed, often taken as a powder mixed with water.

Ashwagandha

This calming adaptogen is an herbal supplement that may help lower cortisol, leaving you feeling less stressed. That may also help with sleep, particularly when stress or anxiety is keeping you awake. One small 2021 study found that ashwagandha improved sleep quality and insomnia symptoms in adults. 

But keep in mind that it doesn’t work immediately—you may need to take it daily for up to 6 weeks before you notice a difference. You can find ashwagandha supplements in doses of around 250 to 600 mg. 

CBD 

CBD is a compound found in cannabis that doesn’t cause a “high.” CBD gummies for sleep are popular, but research on whether CBD actually helps is mixed and a little confusing. 

It has a calming effect on the nervous system that may help, but some studies look at CBD combined with THC, so it’s hard to know how well CBD works on its own. And one small study found that CBD didn’t significantly improve moderate to severe insomnia.

Is It Safe to Take Sleep Gummies Every Night?

It may be safe to take certain sleep supplements every night. But for many gummies, it's not a long-term solution, either. 

Take melatonin, for example. It isn’t considered habit-forming, but extremely high doses (around 250 mg or more) have also been linked to worsening depression, and we still don’t know enough about the effects of long-term use. So, if you find yourself reaching for a melatonin gummy every night, it may be worth talking with your clinician about what’s making it hard to sleep in the first place.

Here are a few other things to consider with nightly use:

• Added sugar: A lot of popular sleep gummies contain added sugar to make them taste good. That can add up if you’re taking gummies every night—especially if you’re already keeping an eye on your blood sugar or added sugar intake.
• Psychological reliance: The sleep gummies we covered may not be physically addictive. But adding them to your nightly routine can make you feel like you need a supplement to fall asleep, even if you don’t. 
• Side effects: Sleep supplements like melatonin can come with side effects like nausea, headaches, vivid dreams, and next-morning grogginess.
• Masking other issues: Sleep gummies may help in the short term without addressing why you’re having trouble sleeping to begin with. If the gummy seems to be working, you may put off getting evaluated to figure out what’s actually causing your sleep issues.

Why Some Sleep Gummies Don’t Work in Midlife

Sleep gummies might help you catch some Zzzzs, but they won’t necessarily treat what’s keeping you awake.

Hormone changes during perimenopause and menopause can contribute to a host of sleep problems. As estrogen and progesterone fluctuate and decline, you may have more trouble falling or staying asleep. Declining progesterone may cause you to lose some of its natural calming effects, while changes in estrogen can contribute to hot flashes and night sweats. That makes for a rough night: You might fall asleep just fine, only to wake up hot and sweaty at 2 or 3 a.m.

The active ingredients in many sleep gummies might help, but they’re not a cure-all. Magnesium or melatonin gummies, for example, could make it easier to drift off, but they may not help you stay in dreamland the whole night. (Midi’s Nightly Steady Sleep+ was built exactly for that purpose, helping you stay asleep and helping reduce nighttime restlessness and awakenings.)

But there may be other reasons you’re not sleeping well. Hormone shifts, along with aging and body composition changes, may increase the risk of sleep apnea after menopause. Sleep gummies won’t treat the issue and could make it easier to overlook. 

There’s nothing wrong with trying sleep supplements, but other treatments may target what’s actually disrupting your sleep in midlife. If hot flashes or night sweats are the culprit, hormone therapy can help reduce these symptoms and improve sleep.

If you’re not sure what’s keeping you up, a Midi clinician can help pinpoint the cause and suggest the best way to treat it.

Interactions and Who Should Skip Sleep Gummies

Gummies for sleep might be made with natural ingredients, but that doesn’t mean they’re the right fit for everyone. Certain combination products can also make it harder to keep track of how much of each active ingredient you're getting. Depending on what’s in them, sleep supplements may interact with medications or make certain health conditions harder to manage.

• Blood thinners: Melatonin may interact with the blood thinner warfarin, potentially affecting how well your blood clots. If you take this medication, check with your clinician or pharmacist before using melatonin. 
• Thyroid medications: Ashwagandha can increase thyroid hormone levels, so it may interfere with medications like levothyroxine.
• Blood pressure and diabetes medications: Some sleep supplement ingredients can affect blood pressure or blood sugar. Ashwagandha, for example, can interact with blood pressure and diabetes medications. 
• Antidepressants and other sedatives: Taking melatonin or other sleep supplements with medications that make you drowsy can leave you extremely tired or unsteady during the day. This includes certain antidepressants, prescription sleep aids, and gabapentin, a medication used for seizures and nerve pain.
• Seizure medications: Research on how melatonin and other supplements affect seizures is limited. So if you take seizure medications, don't try a sleep supplement without your clinician's approval.
• CBD: It's a popular sleep supplement, but CBD can affect how your liver processes certain medications, which can change how well they work.
• Alcohol: Combining alcohol with melatonin or other sleep gummies can make you less alert and increase drowsiness, so it’s best not to mix them.

It’s always a good idea to talk with your clinician or pharmacist before adding a sleep supplement to your routine, especially if you take prescription medications. They can go over your health history and help determine which one, if any, is the best fit for you.

Better Options if Gummies Aren't Working

Not a fan of gummies? Midi's Nightly Steady Sleep+ powder is another option, formulated with glycine to help promote your body’s natural nighttime cooling, magnesium glycinate to help calm your mind, and zinc to support steadier sleep. (You can also consider Midi’s Daily Cortisol Support capsules, designed to help women support sleep quality and stress relief.)

Beyond supplements, though, there are other ways to treat sleep issues, especially during midlife. They often involve tackling the root cause rather than just treating the symptoms. 

Improved sleep hygiene and lifestyle changes

Before you reach for medication, try making some lifestyle adjustments. This can include sleep hygiene strategies, such as: 

• waking up and going to bed at the same time every day 
• getting some natural light in the morning 
• avoiding caffeine in the afternoon and evening 
• avoiding screens for 30 to 60 minutes before bed
• cutting alcohol 3 to 4 hours before bed 
• keeping your bedroom dark, quiet, and cool 
• creating a nightly wind-down routine 
• exercising during the day to help you fall asleep more easily at night

Cognitive behavioral therapy for insomnia (CBT-I)

CBT-I is a go-to option for chronic insomnia. This evidence-based treatment helps you identify thoughts, feelings, and behaviors that could be contributing to insomnia and develop habits that support better sleep. Research suggests it can improve insomnia symptoms and sleep quality in menopausal women.

Prescription sleep medications

If your sleep issues are severe or affecting your everyday life, a prescription medication may be worth considering. Micronized progesterone (Prometrium) might be one option. This form has the same chemical structure as the progesterone that your body naturally produces, and it can have a calming effect that promotes sleep. If you’re interested in prescription options, speak with a clinician, who can help you find the right fit.

Hormone therapy 

If hot flashes and night sweats are keeping you up at night, hormone replacement therapy (HRT, now commonly referred to as menopause hormone therapy, or MHT) can help. HRT works by supplementing the hormones, especially estrogen and progesterone, that decline around menopause. It’s the gold standard for treating these vasomotor symptoms. 

And fewer hot flashes and night sweats could mean much better sleep. In fact, HRT has been shown to improve sleep quality in menopausal women, particularly when vasomotor symptoms are part of the problem.

How to Choose a Sleep Gummy if You Want to Try One

If you want to give sleep gummies a try, keep these tips in mind: 

• Shop smart: Before buying sleep gummies, look for reputable brands that use independent third-party testing to verify what’s in the product. It’s an important first step, considering that supplements don’t always contain exactly what their labels claim. One study found that 22 of 25 melatonin gummies contained different amounts of melatonin than their labels claimed. One even contained CBD but no detectable melatonin.
• Keep the formula simple: Look for products that clearly list how much of each active ingredient they contain, rather than long blends with unclear amounts.
• Watch out for added sugar: Check the added sugar content and full ingredient list, and look for a lower-sugar option if possible.
• Check for drug interactions: Don’t start taking a gummy without being sure it won’t interact with medications you’re already taking.
• Start with a low dose: Even if a supplement is natural, it can still have side effects. Consider starting with a low dose, especially when it comes to melatonin, since higher doses aren’t always more effective.
• Talk with a clinician first: A trusted clinician can help you decide whether a sleep gummy makes sense for you. They can also take your health history into consideration and advise you on what other options you might have.

And if you’re still not sure what’s right for you, you don’t have to figure it out alone. Sleep problems in midlife can have more than one cause. A Midi clinician can help you get to the bottom of what’s disrupting your sleep and build a treatment plan that fits your needs, whether that includes lifestyle changes, hormone therapy, or other options.

Key Takeaways

• Sleep gummies are OTC supplements that contain ingredients like melatonin, magnesium glycinate, and CBD. What’s inside—and how much—can vary widely from one product to the next.
• Melatonin gummies have been shown to help adults fall asleep faster, but they won’t necessarily help if you're waking up in the middle of the night.
• Other popular sleep supplement ingredients, such as L-theanine, glycine, and ashwagandha, may help you fall asleep or get better sleep, but the evidence varies by ingredient and is still limited in some cases.
• Sleep gummies are not always the best option for midlife women. Menopausal hormone changes, hot flashes, and night sweats can disrupt sleep in ways that a gummy can’t fix.
• If you want to try a sleep gummy, look for third-party testing, clearly listed ingredients, and a research-informed formula. And check with your clinician before starting a new supplement, especially if you take medications or aren’t sure what’s causing your sleep problems.

Frequently Asked Questions (FAQs)
