The Importance of Quality Sleep
Getting enough quality sleep is essential for mental clarity, emotional well-being, and overall physical health. According to the Centers for Disease Control and Prevention (CDC), nearly 1 in 3 American adults regularly falls short of the recommended 7 or more hours of sleep each night. While improving sleep hygiene—such as maintaining a consistent sleep schedule and reducing screen exposure before bed—is often the first line of defense, many people turn to over-the-counter (OTC) remedies for additional support.
But which OTC sleep aids do neurologists actually recommend? In this guide, we’ll explore the science of sleep and highlight expert-endorsed OTC products that are both safe and effective.
How Sleep Works: The Systems Behind Rest
Understanding how sleep functions makes it easier to grasp how sleep aids work. Two primary systems regulate your sleep-wake cycle:
– The circadian rhythm, your internal 24-hour clock, responds to light exposure and helps manage your sleep-wake schedule.
– The homeostatic sleep drive builds pressure to sleep the longer you’re awake.
These systems can be disrupted by factors such as stress, inconsistent lighting, travel, or shift work. Key internal chemicals—melatonin, cortisol, and adenosine—also play roles in helping you fall asleep and stay asleep. When these natural rhythms are out of sync, sleep disturbances can occur.
Fortunately, OTC sleep aids can help support these processes for short-term use, as long as they work with your body’s natural rhythms and not against them.
Melatonin: Gentle Support for Your Sleep Cycles
Melatonin is one of the most commonly used and neurologist-endorsed sleep supplements. This natural hormone is released by your brain in response to darkness and signals that it’s time to wind down for sleep.
“Melatonin is especially helpful for people dealing with circadian rhythm disturbances—such as jet lag, shift work disorder, or delayed sleep phase syndrome,” says Dr. Raj Dasgupta, a neurologist and sleep medicine expert.
Unlike stronger sleep medications, melatonin doesn’t sedate you. Instead, it helps guide your body toward its natural sleep rhythms.
– Recommended dose: 0.5 to 3 mg, taken 1 to 2 hours before bedtime
– Avoid high doses, as they may interfere with your body’s natural melatonin production
– For those who wake during the night, a time-release version may offer longer-lasting support
Magnesium: A Relaxing Mineral for Rest
Magnesium is another neurologist-recommended option. This essential mineral plays a core role in regulating GABA, a neurotransmitter known for its calming effects. Low magnesium levels are linked to poor sleep and nighttime restlessness.
“Magnesium glycinate is my go-to form for patients, as it’s gentle on the digestive system and highly absorbable,” says Dr. Michael Breus, a clinical psychologist and specialist in sleep medicine.
Magnesium is particularly helpful for people who experience muscle tension, anxiety, or frequent awakenings.
– Recommended dose: 200 to 400 mg, taken 30 to 60 minutes before bed
– Preferred forms: Magnesium glycinate or magnesium citrate
– Avoid magnesium oxide, which is poorly absorbed and may cause stomach discomfort
L-Theanine: Calm Your Mind Before Bed
If racing thoughts or anxiety keep you awake, L-theanine may provide the mental calm you need to fall asleep. This amino acid, naturally found in green tea, promotes relaxation by increasing levels of serotonin, dopamine, and GABA—without making you feel drowsy.
“L-theanine works well for individuals who battle mental chatter at bedtime,” explains Dr. Shelby Harris, a behavioral sleep medicine expert.
You can take L-theanine on its own or combine it with melatonin or magnesium for more comprehensive support.
– Recommended dose: 100 to 200 mg, taken 30 to 60 minutes before sleep
– Combines well with magnesium or melatonin
– No morning grogginess, making it a great everyday option
Antihistamines: Use Occasionally, Not Daily
You might reach for an OTC medication like diphenhydramine (Benadryl) or doxylamine (Unisom) when sleep is elusive. However, neurologists warn against using these medications regularly.
“These antihistamines block histamine, which promotes alertness, but they can also impair cognitive function and cause lingering grogginess the next morning,” warns Dr. Harris.
While these medications may provide short-term relief during travel or illness, they are not a long-term solution.
– Use sparingly—no more than a few nights per month
– Be aware of side effects, including drowsiness and disrupted REM sleep
– Never mix with alcohol or other sedatives
CBD: Promising but Use With Care
CBD (cannabidiol) has gained traction as a natural sleep aid due to its potential calming effects. Though studies are still emerging, some people find that CBD helps reduce anxiety and improve sleep quality.
“CBD is promising, but there’s a wide variation in product quality,” says Dr. Dasgupta. “Look for products that are third-party tested, clearly labeled, and contain no THC.”
Always consult with your healthcare provider before starting CBD, especially if you take prescription medications.
– Starting dose: 10 to 20 mg, taken 30 to 60 minutes before bedtime
– Choose high-quality, lab-tested CBD from reputable sources
– Avoid products with undisclosed THC or unclear labeling
Smart Guidelines for OTC Sleep Aid Use
To ensure you’re using OTC sleep aids responsibly and effectively, follow these expert tips:
Do:
– Use OTC sleep aids for temporary relief, not as long-term solutions
– Support supplements with solid sleep hygiene—consistency, limited screen time, and a sleep-friendly environment
– Consult a healthcare provider if sleep issues persist for more than two weeks
Don’t:
– Mix sleep aids with alcohol or sedatives
– Rely on antihistamines nightly
– Assume that a supplement is risk-free just because it’s labeled “natural” — always check for drug interactions and potential side effects
When to See a Specialist for Ongoing Sleep Trouble
If your sleep struggles continue for several weeks or you still feel fatigued despite getting 7 or more hours of rest, it may be time to consult a neurologist or sleep specialist.
Conditions such as insomnia, sleep apnea, and restless leg syndrome require professional evaluation and may benefit from tools such as sleep studies or cognitive behavioral therapy for insomnia (CBT-I).
Don’t struggle alone—certified sleep professionals can create personalized treatment plans involving lifestyle changes, therapy, and when appropriate, prescription support.
Final Thoughts: Build Better Sleep Habits Today
Sleep is just as vital to your health as nutrition and exercise. When used appropriately, neurologist-recommended OTC sleep aids can help restore healthy rest—particularly during times of stress, travel, or routine disruption.
Ultimately, lasting sleep improvement requires a holistic approach. Combine evidence-based supplements with strong nightly routines, professional guidance, and a consistent commitment to wellness.
