These Are the Best Vitamins for Sleep and Anxiety in Midlife

Maybe you can fall asleep just fine, but you wake up several times during the night. Or maybe your brain suddenly decides bedtime is the perfect moment to mull over tomorrow’s to-do list—or worse, replay every awkward moment you’ve had over the past month (or ever). Sound familiar? 

Among perimenopausal women, 38-56% report having trouble sleeping, and a slightly higher number of postmenopausal women say the same—not a big surprise when you consider night sweats, achy joints, and the need to pee more often than before. And as if that weren’t enough, sleep disruptions can amp up stress and anxiety. 

Given all this, you may have found yourself on the hunt for the best vitamins for sleep and anxiety. There are countless options, but the right choice for you depends on your symptoms, overall health, and any medications you’re taking. It’s also important to consider support for menopause symptoms, chronic stress, or underlying sleep issues.

Let’s sort through which sleep supplements and supplements for anxiety may be worth considering, as well as when it makes sense to work with a healthcare professional, like a Midi clinician. 

Best Vitamins for Sleep and Anxiety: Start With the Symptom Pattern

Supplement shopping can get confusing fast, because you have a lot of options promising different solutions. And if, say, you have trouble falling asleep, you may need a different strategy than if you’re waking up at 3 a.m.

Plus, poor sleep can lead to anxiety, making it harder to regulate your emotions and cope with stress. That can leave you feeling foggy, irritable, and overwhelmed, which is why poor sleep and anxiety can feed off each other.

A smart route to finding the best vitamins for sleep and anxiety starts with understanding the contributing factors to your symptoms. Is it daytime stress, too much time in front of screens, an irregular sleep schedule, or maybe even hot flashes, a thyroid disorder, or iron deficiency? Understanding this can help you start to think about potential solutions.

For instance, if your brain goes into overdrive at bedtime, a supplement that promotes relaxation may help. If you have trouble falling asleep, you may get help from something that supports your body’s sleep-wake cycle.

Best Supplements and Vitamins for Sleep: Which Options Come Up Most Often

While research on sleep supplements is mixed overall, a study review found that some natural sleep aids may help reduce insomnia and improve sleep quality. Here’s a rundown of the most talked-about sleep supplements: 

• Melatonin is probably the most recognizable one. Your body naturally makes this hormone to help regulate your circadian rhythm, or sleep-wake cycle. The research isn't definitive, but a study review on melatonin and the menopausal transition indicated there's some evidence that it may help with sleep during this period. 
• Magnesium is a mineral that helps support muscle and nerve function, among other body processes. Some research suggests that it may help with sleep if magnesium levels are low or if stress and muscle tension are disrupting sleep. Another study review showed that magnesium may help improve sleep quality, but the researchers noted that more clinical studies are needed.
• Vitamin D helps keep your bones, muscles, and immune system healthy. It might be suggested for sleep, because vitamin D deficiency has been linked to poorer sleep quality and more daytime sleepiness. But research is mixed on vitamin D supplements as a sleep fix. 
• L-theanine, an amino acid found in tea leaves, is popular among people who have trouble calming racing thoughts or winding down at bedtime, and some clinical trials have supported this.
• Chamomile and valerian are herbal remedies sometimes sold as "natural sleep aids." In a small study, postmenopausal women who took valerian reported better sleep quality than a placebo group. And a review found that chamomile improved sleep quality and reduced nighttime awakenings, though results have been inconsistent.
• Gamma-aminobutyric acid (GABA) is a neurotransmitter, or chemical messenger, that helps quiet brain activity. Some sleep supplements include GABA, and there’s some evidence that it may help you snooze by reducing stress, but researchers are still studying these effects.
• 5-HTP is a compound your body uses to make melatonin and the mood-boosting chemical serotonin. It’s been linked to better sleep quality in some small studies in older adults, but there isn't enough high-quality evidence to know whether it reliably improves sleep.
• CBD, or cannabidiol, is a compound in cannabis that doesn’t have psychoactive effects (meaning it doesn’t get you high). Some research suggests that CBD may help reduce symptoms in people with anxiety disorders, but most studies on CBD don’t support its benefits on sleep.
• Ashwagandha, an adaptogen, has been shown in some research to have benefits for sleep. 

Vitamins for Anxiety: What May Help

Here’s the science on the supplements often mentioned for anxiety—on all of these, though, the evidence is still either slim or not established:

• Magnesium: One of this mineral’s jobs is to regulate your body’s stress-response system, and low magnesium levels have been linked to increased anxiety. One research review found that magnesium supplements may help people with mild to moderate anxiety.  
• B vitamins: These nutrients help your brain and nervous system function. Being deficient in one or more B vitamins can contribute to fatigue, low mood, and brain fog—symptoms that overlap with stress and anxiety. Some small studies have shown that vitamin B6 supplement helped people feel less anxious after 4 weeks. 
• Omega-3 fatty acids: Some research suggests that omega-3 supplements may help improve anxiety symptoms, particularly in people with diagnosed clinical anxiety, but the evidence is still evolving. 

Another point to keep in mind: Nutrient deficiencies are only one piece of the puzzle when it comes to anxiety. For many women, anxiety in midlife has a lot to do with hormonal shifts and life stress. Natural supplements for anxiety may help, but they’re best as part of a broader health strategy.

Natural Supplements for Anxiety and Stress-Related Sleep Problems

When stress and anxiety are keeping you up at night, it can be hard to tell where one problem ends and the other begins. One challenge when considering a supplement is that sometimes the effects are modest, not dramatic.

Some of the supplements mentioned—including L-theanine, magnesium, chamomile, and valerian—are often taken for anxiety as well as sleep, since taking the edge off of stress could make it easier to wind down at bedtime. 

But rather than working like a sleeping pill, they’re designed to foster a sense of calm. They're usually most effective as part of a broader approach for addressing occasional sleep disturbances and managing stress.

If anxiety is persistent, worsening, or affecting your daily life, it's worth talking with a healthcare professional—like one of Midi’s clinicians—about a comprehensive treatment plan.

How to Choose Sleep Supplements Safely in Midlife

“Natural” doesn’t always mean safe or effective. With supplements, the quality, ingredients, and dosing can vary widely from one brand to the next. Be sure to read the labels carefully and choose products that have been third-party tested. 

Keep these tips in mind when considering a new supplement:

• Match the supplement to the symptom: Can't fall asleep? Melatonin might be more helpful than magnesium. Keep waking up at 3 a.m.? Think about what’s waking you up—if it’s night sweats, for example, then menopause-focused care is worth considering. 
• Check for medication interactions: Some supplements—like valerian, 5-HTP, and GABA—can interact with antidepressants, blood thinners, and other medications. It’s a good idea to ask your healthcare professional about any new supplements.
• Simpler formulas may be better than PM blends: Multi-ingredient sleep products may contain supplements that haven't been well studied together. Starting with a single ingredient also makes it easier to figure out whether it’s helping. And stacking multiple calming products may increase the risk of side effects.
• Remember, alcohol and supplements don’t mix: Combining the two may lead to dizziness, grogginess, and other side effects. (And alcohol is known to be a sleep-disrupter, anyway.)

Midlife-Specific Reasons Sleep and Anxiety Feel Worse

Midlife can create the perfect storm for both disrupted sleep and anxious thoughts. Declining estrogen levels have been linked to sleep problems like falling and staying asleep, while lower progesterone levels may contribute to disrupted or less restorative sleep. And because progesterone also affects neurotransmitters like GABA, which play a role in relaxation and sleep, some women find it harder to unwind at night.

It's important to remember that conditions like sleep apnea, thyroid issues, or mood disorders can cause similar symptoms. If an underlying issue isn't addressed, even the best supplement can only help so much. Ongoing sleep or anxiety problems warrant a conversation with a healthcare professional, so you can get help setting up a comprehensive plan.

What Usually Helps More Than Supplements Alone

Sleep supplements and vitamins for anxiety can be helpful tools. But lifestyle shifts can make a big difference in helping you deal with both issues: 

• Keep a consistent sleep schedule: Going to bed and waking up around the same time every day helps keep your body’s sleep-wake cycle on track. A relaxing nighttime routine—like reading, taking a warm bath, or doing gentle stretches—can help, too. 
• Limit or cut caffeine and alcohol later in the day: Caffeine can stay in your system for hours and make it harder to fall asleep later. Alcohol can sabotage sleep if you have it too close to shut-eye. Try to limit caffeine after mid-afternoon and avoid alcohol at least 2 hours before bedtime. 
• Make movement part of your routine: Regular exercise, including strength training, supports sleep, mood, and overall health. Physical activity has been shown to lessen symptoms of anxiety and depression in women during the menopausal transition and beyond.
• Consider other support: Therapy, including cognitive behavioral therapy for insomnia, can help address patterns that may contribute to poor sleep and anxiety. Mindfulness practices and relaxation techniques, such as yoga and deep breathing, can also help you get a handle on anxiety. 
• Treat underlying causes: Hot flashes, chronic stress, and other symptoms often require more targeted treatment than supplements can provide. Hormone replacement therapy (HRT, now commonly referred to as menopause hormone therapy or MHT) may relieve hot flashes and night sweats to help ease sleep problems, fatigue, and mood changes.

When to Work With a Clinician Instead of Self-Treating

It's worth checking in with a healthcare professional, especially if anxiety or sleep disruptions start taking a toll on your daily life. But you don't have to wait until symptoms become severe. A clinician, like the menopause specialists at Midi, can help identify underlying causes, recommend treatments tailored to your symptoms, and give personalized guidance to help you navigate perimenopause and menopause.

It’s especially important to get help if you:

• have insomnia for weeks at a time or feel exhausted during the day
• have anxiety that feels frequent, intense, or difficult to manage on your own
• snore loudly, wake up gasping for air, have restless legs, or experience severe night sweats
• Notice physical symptoms such as palpitations, shortness of breath, jitteriness, or restless legs
• notice symptoms of depression or panic or experience side effects after starting a medication or supplement

Key Takeaways 

• The best vitamin for sleep and anxiety depends on your symptoms. Trouble falling asleep, waking up overnight, and anxiety may each require a different approach.
• Melatonin, magnesium, and L-theanine are among the more popular supplements for sleep and anxiety. They may make it easier to fall asleep, ease stress, or promote relaxation, but the research is mixed and benefits tend to be modest. 
• If you decide to try a supplement, start with one product at a time, look for brands with third-party testing, and check with a healthcare professional before combining supplements with other medications.
• Sleep supplements work best as part of a bigger plan that includes healthy sleep habits, regular exercise, and stress management.
• Hormone shifts, hot flashes, and life stress can all contribute to sleep problems and anxiety for women in midlife. 

Frequently Asked Questions (FAQs)

What are the best vitamins for sleep and anxiety?

There’s no single best option for everyone. The right choice depends on your symptoms, overall health, and any medications you take.

Are sleep supplements safe to take every night?

No, not necessarily. Some sleep supplements are generally considered safe for short-term use, but others can cause side effects or interact with medications. If you're thinking about taking a sleep supplement every night, it's a good idea to check with a healthcare professional.

What is the best vitamin for sleep if I wake up during the night?

There isn't a quick fix or one-size-fits-all option. The answer depends on why you're waking up in the middle of the night. It could be tied to stress, hot flashes, sleep apnea, or other issues. Identifying and treating the cause are the most effective steps.

Do supplements for anxiety really work?

Some have limited or early evidence behind them, but they aren't a cure-all, and benefits are usually modest. Some supplements for anxiety may help when stress, poor sleep, or a nutrient deficiency are part of the problem. The evidence is mixed, and results can vary widely from person to person.

Is magnesium a good sleep aid?

Magnesium may help some people relax and sleep better, especially if stress, muscle tension, or low magnesium intake are contributing to poor sleep. But it's not a cure for insomnia, and the research on magnesium for sleep is still mixed.

When should I stop self-treating sleep and anxiety with supplements?

It’s worth talking with a healthcare professional about sleep or anxiety symptoms, because the best treatment plan is personalized and based on your symptoms. It’s definitely important if your symptoms have lasted for weeks and are affecting your daily life.
