The 5 Best Natural Sleep Aids (And Which to Avoid)
Let's be honest—we're in the middle of a sleep crisis. Between the blue light from our devices, constant stress, and overbooked schedules, quality sleep feels more elusive than ever. If you're one of the 70 million Americans struggling with sleep, you've probably considered reaching for some help.
But which natural sleep aids actually work? And which might leave you foggy-headed or cause more problems than they solve?
I've spent years testing different sleep solutions (some successful, some disastrous), and I'm breaking down what actually works—without the marketing hype. If you're tired of staring at the ceiling at 2 AM, this guide is for you.
How We Evaluated Each Option
Not all "natural" sleep aids are created equal. Here's what matters:
- Effectiveness : Does it actually help you fall asleep AND stay asleep?
- Morning After : How do you feel when you wake up? Alert or zombie-like?
- Safety Profile : Is it safe for regular use without dependency?
- Science Backing : Is there research supporting the claims?
- Compatibility : Does it work with your body's natural sleep mechanisms or override them?
Let's dive into the solutions that passed the test—and a few popular options you might want to reconsider.
Quick Comparison: Natural Sleep Aid Options
| Sleep Aid | Best For | Morning After | Dependency Risk | Key Benefit |
|---|---|---|---|---|
| NightRoot Blend | Stress & racing thoughts | Clear-headed | Very Low | Complete solution for mind & body |
| Magnesium Glycinate | Muscle tension | Can cause grogginess | Low | Physical relaxation |
| CBD | Pain-related sleep issues | Generally clear | Low | Pain & anxiety reduction |
| Glycine | Temperature regulation | Clear-headed | Very Low | Improves sleep quality |
| Lemon Balm | Mild sleep issues | Clear-headed | Very Low | Gentle calming |
| Melatonin | Temporary jet lag | Often groggy | Moderate | Quick onset |
Now let's explore each option in detail:
The 5 Best Natural Sleep Aids
1. Ashwagandha + L-Theanine Combinations (NightRoot)
What it is : A synergistic blend of stress-adapting ashwagandha with the calming amino acid L-theanine, often combined with complementary herbs like lemon balm and chamomile.
Why it works : Rather than forcing sleep, this combination addresses the root causes of sleeplessness—primarily stress, anxiety, and an overactive mind. Ashwagandha helps regulate cortisol (your stress hormone) while L-theanine promotes alpha brain waves associated with relaxation without drowsiness. The lemon balm and chamomile provide additional gentle calming effects that enhance the formula's overall effectiveness.
Best for : People whose sleep issues stem from stress, overthinking, or anxiety. Perfect if you fall asleep but wake up at 3 AM with racing thoughts.
The science : A 2019 double-blind study found that ashwagandha extract significantly improved sleep quality and helped participants fall asleep faster [1]. L-theanine has been shown to reduce resting heart rate and promote relaxation without sedation [2]. For a deeper dive into how ashwagandha specifically supports sleep, check out our detailed comparison of melatonin vs. ashwagandha for sleep .
What we love : NightRoot by Restful Rootz perfects this combination in a delicious gummy form, using all four of these powerful ingredients (ashwagandha, L-theanine, lemon balm, and chamomile). It promotes natural sleep transitions without the groggy "sleep hangover" of other options. Users report waking up feeling refreshed rather than drugged. Learn more about how L-theanine helps with sleep and the calming effects of chamomile in our detailed ingredient guides.
Limitations : Takes a few nights to reach full effectiveness for some people. Works best when combined with good sleep hygiene.
2. Magnesium Glycinate
What it is : A highly absorbable form of magnesium, an essential mineral that many Americans are deficient in.
Why it works : Magnesium helps activate the parasympathetic nervous system (your "rest and digest" mode) and regulates neurotransmitters that calm the brain. It also helps relax muscles, relieving physical tension that might keep you awake.
Best for : People with muscle tension, restless legs, or physical restlessness at bedtime. Also excellent for those who clench their jaw at night.
The science : Studies show magnesium supplementation improves sleep efficiency, early morning awakening, and insomnia severity index scores [3].
Limitations : Can cause digestive issues in some people if taken in too high doses. A significant subset of users (myself included) report substantial morning grogginess with magnesium—almost like a "sleep hangover" that can last well into the afternoon. If you try magnesium and feel unusually tired the next day, you're not alone!
3. CBD (Without THC)
What it is : Cannabidiol, a non-psychoactive compound from hemp plants.
Why it works : CBD interacts with the endocannabinoid system, which helps regulate sleep stability. It shows particular promise for reducing anxiety without the "high" associated with THC.
Best for : People with pain-related sleep issues or anxiety that doesn't respond to other interventions.
The science : Early research shows CBD may help with both falling asleep and staying asleep, particularly by reducing anxiety. A 2019 study found that 66.7% of patients experienced better sleep within the first month of CBD use [4].
Limitations : Quality and potency vary dramatically between products. Can be expensive for effective doses. Some people experience vivid dreams.
4. Glycine
What it is : An amino acid that acts as an inhibitory neurotransmitter in the brain.
Why it works : Glycine lowers core body temperature, signaling to your body that it's time to sleep. It also improves sleep quality by enhancing REM sleep cycles.
Best for : People who struggle with temperature regulation at night or those who experience fragmented sleep.
The science : Research shows that 3g of glycine before bed helps participants fall asleep faster and improve subjective sleep quality [5].
Limitations : Effects can be subtle compared to other options. Works best for minor sleep issues rather than chronic insomnia.
5. Lemon Balm
What it is : A lemon-scented herb in the mint family with calming properties.
Why it works : Lemon balm increases GABA activity in the brain, a neurotransmitter that promotes relaxation. It creates a gentle calming effect without sedation.
Best for : People with mild sleep issues, particularly those with nervous energy or digestive discomfort at bedtime.
The science : Studies show lemon balm improves sleep quality and reduces symptoms of insomnia when used consistently [6]. For a comprehensive look at this powerful herb, read our guide to lemon balm for sleep .
Limitations : Effects are gentle; may not be strong enough for severe sleep issues. Works best when combined with complementary herbs (which is why it's one of the key ingredients in NightRoot alongside ashwagandha, L-theanine, and chamomile).
Popular Sleep Aids You Might Want to Reconsider
Melatonin: Proceed with Caution
Melatonin is easily the most popular natural sleep aid, but it comes with significant drawbacks:
The problem : Melatonin is a hormone, not an herb. Supplementing regularly can potentially disrupt your body's natural production and create dependency.
Common complaints :
- Morning grogginess that can last for hours
- Vivid or disturbing dreams
- Headaches and dizziness
- Waking up in the middle of the night when it wears off
- Becoming less effective over time
When it might make sense : Occasional use for jet lag or temporary sleep schedule disruptions. Short-term use only.
Valerian Root: Mixed Results
The problem : While some people swear by valerian, research results are inconsistent. Many people report a "hangover effect" similar to melatonin, and a small percentage actually experience the opposite effect—increased energy and insomnia.
Limitations : Strong earthy smell and taste that many find off-putting. May interact with certain medications.
Diphenhydramine (Benadryl): Not as Safe as You Think
The problem : While technically "over-the-counter," this antihistamine comes with concerning side effects when used regularly for sleep:
- Increased dementia risk with long-term use
- Significant morning grogginess
- Quickly builds tolerance, requiring higher doses
- Dry mouth, constipation, and urinary retention
Better alternative : If you need something stronger than herbal options, talk to a healthcare provider about safer short-term solutions.
Finding Your Perfect Sleep Solution
The best natural sleep aid for you depends on what's keeping you awake:
- Racing mind and anxiety? Ashwagandha + L-theanine combinations like NightRoot are likely your best bet.
- Physical tension and restlessness? Start with magnesium glycinate.
- Pain-related sleep issues? Consider CBD products from reputable sources.
- Temperature regulation problems? Try glycine before bed.
- Mild sleep issues or digestive discomfort? Lemon balm could provide gentle relief.
Beyond Supplements: Enhancing Your Sleep Naturally
Even the best sleep supplements work better when combined with good sleep practices:
- Consistent schedule : Going to bed and waking up at the same time regulates your circadian rhythm.
- Light management : Reduce blue light exposure in the evening and get bright light first thing in the morning.
- Temperature : Keep your bedroom cool (around 65°F is ideal for most people).
- Worry time : Spend 15 minutes before bed writing down what’s on your mind—then gently remind yourself, “I’ve done all I can for today."

My Personal Experience
After years of sleep struggles, I've found that the ashwagandha + L-theanine + lemon balm + chamomile combination in NightRoot works best for my typical "mind won't shut off" insomnia. I fall asleep naturally (no drugged feeling), stay asleep through the night, and wake up clear-headed.
I tried magnesium glycinate for a while because it was so highly recommended, but found myself feeling foggy and groggy well into the afternoon the next day. After talking with others, I discovered this reaction is more common than many articles suggest.
What makes the NightRoot approach different is that it supports my body's natural sleep mechanisms rather than overriding them. I'm not knocking myself out—I'm giving my nervous system the support it needs to transition into restful sleep on its own.
The result? Better sleep, better days, and a better relationship with bedtime.

For most people dealing with stress-related sleep issues, adaptogenic combinations like NightRoot offer the most balanced approach with the fewest side effects.
Whatever you choose, remember that quality sleep isn't a luxury—it's essential maintenance for your brain and body. Investing in better sleep pays dividends in every area of your life.
