Two cannabinoids keep showing up in sleep products right now. CBN and CBD. They both come from the same hemp plant we grow on our USDA Organic farm in Wilmore, Kentucky. Once they're in your system, though, they do different jobs.
The short version: CBN has the better clinical evidence for helping you stay asleep. CBD has the stronger research for calming the anxiety that keeps you from falling asleep in the first place. Sometimes you want both.
This post walks through what each cannabinoid actually is, what the 2023 and 2024 clinical studies found, and how to pick between them for your specific sleep problem.
What Is CBN? (Quick Primer for Non-Scientists)
CBN is short for cannabinol. It's a minor cannabinoid that forms naturally when THC ages and breaks down from exposure to heat, air, and light. Older cannabis tends to have more of it because the THC has had time to oxidize. That's also why CBN was one of the first cannabinoids ever isolated, back in the 1940s, long before THC and CBD were characterized.
On the hemp side, CBN shows up in small amounts in mature flower and can be extracted, concentrated, and blended into gummies, tinctures, and other products. Commercial CBN can also be produced through controlled oxidation of hemp-derived cannabinoids. Either way, the CBN in a legal hemp product is the same molecule: C21H26O2.
CBN is non-intoxicating at the levels found in legal hemp products. It's federally compliant when sourced from hemp containing less than 0.3% Delta-9 THC, which is what the 2018 Farm Bill allows.
People reach for CBN because early clinical research suggests it may help with sleep maintenance. That's staying asleep, not falling asleep. We'll get to the study data below.
What Is CBD? (And How It Differs from CBN)
CBD is short for cannabidiol. It's the most studied cannabinoid outside of THC, with peer-reviewed research on anxiety, inflammation, and seizure disorders going back more than a decade. The FDA has even approved a CBD-based prescription drug, Epidiolex, for specific pediatric seizure conditions, which is the strongest regulatory signal any cannabinoid currently has.
Like CBN, CBD is non-intoxicating. Unlike CBN, CBD is present in hemp flower in large amounts and forms directly in the growing plant rather than as a breakdown product of THC. It's the headline cannabinoid in most full spectrum CBD products.
The big functional difference between the two for sleep purposes comes down to what they seem to do once they're in your system. CBD interacts with serotonin receptors (specifically 5-HT1A) and the endocannabinoid system in ways that tend to reduce anxiety. CBN interacts with the endocannabinoid system in ways that may produce mild sedation at higher doses. That's a real distinction, and it matters for which product you pick.
How CBN and CBD Affect Sleep Differently
CBN: The Sleep Maintenance Cannabinoid
The headline from recent clinical research: CBN seems to reduce how often you wake up during the night. That's sleep maintenance. If you fall asleep fine at 10 PM but snap awake at 2 AM and can't get back under, CBN is the cannabinoid being actively studied for that problem.
The effect isn't a knockout punch. It's gentler than prescription sleep aids and gentler than high-dose melatonin. The 2023 study covered below used 20mg of CBN per night, which lines up with a typical gummy dose on the market.
CBD: The Relaxation and Anxiety Reduction Cannabinoid
CBD's strongest research isn't actually about sleep directly. It's about anxiety. Anxiety happens to be one of the biggest reasons people can't fall asleep, so the two overlap in practice.
Users report taking CBD in the evening to quiet the mental spin-up that happens when the house goes quiet and they're finally alone with their thoughts. The clinical research on that kind of use is promising but mixed. Some trials show improvement in sleep quality. Others show improvement in well-being scores with no measurable change to objective sleep metrics.
What the Research Says (2023-2026 Clinical Studies)
The 2023 Double-Blind CBN Sleep Study
In October 2023, a double-blind, randomized, placebo-controlled study was published in Experimental and Clinical Psychopharmacology. Participants took either a placebo, 20mg CBN, or 20mg CBN combined with varying doses of CBD (10mg, 20mg, or 100mg) for seven consecutive nights.
The results were interesting. Compared to placebo, 20mg of CBN significantly reduced the number of nighttime awakenings and reduced overall sleep disturbance. There was no significant effect on sleep onset latency, which is the time it takes to fall asleep in the first place. Adding CBD on top of the CBN didn't improve the results in this specific trial.
So CBN helped people stay asleep. It didn't make them fall asleep faster. That's a clean match to the functional distinction between the two cannabinoids. The trial was small by pharmaceutical standards, and larger follow-up studies are still running. The initial signal is encouraging, but no one is claiming CBN is a cure for insomnia based on a single study.
CBD Sleep Research Highlights
The picture for CBD and sleep is less tidy. A 2024 randomized controlled pilot trial in the Journal of Clinical Sleep Medicine gave 150mg of CBD to people with moderate-to-severe insomnia. Sleep onset, sleep efficiency, and wake-after-sleep-onset didn't differ significantly from placebo. The CBD group did report better well-being scores and showed improved objective sleep efficiency after two weeks.
A larger 1,793-participant trial found that 15mg of CBD reduced self-reported sleep disturbance over four weeks. It didn't change how long it took people to fall asleep.
Translation: CBD alone has mixed results in insomnia trials. Where it seems to help most is with how people feel about their sleep and with anxiety that surrounds sleep, rather than with falling asleep faster by lab-measured standards.
This is why we're cautious with any brand claiming CBD will fix insomnia. The research doesn't support that framing. It does support CBD as a reasonable tool for the anxiety side of sleep trouble.
Can You Take CBN and CBD Together for Sleep?
Yes. Many sleep products on the market combine the two.
The Entourage Effect Explained
The entourage effect is the hypothesis that cannabinoids and terpenes work better in combination than they do in isolation. It's why full spectrum hemp products often include CBN, CBG, CBC, and trace terpenes alongside the primary CBD. The idea dates back to a 1998 paper by Dr. Ethan Russo and has been a throughline in cannabis research ever since, though the clinical evidence is still thinner than most product marketing suggests.
In practice, that's why sleep gummies often pair a moderate dose of CBD with CBN. The reasoning goes: CBD handles the anxiety piece, CBN handles the maintenance piece, and you get broader coverage than a single-cannabinoid product.
The honest caveat is that the 2023 CBN study didn't show additional benefit from layering CBD on top of CBN. That doesn't rule out the entourage effect in other formulations or at other doses. It just means one controlled study didn't confirm it for this specific question.
How to Choose Between CBN and CBD Products for Sleep
When CBN Is the Better Choice
You fall asleep fine but wake up in the middle of the night and can't get back under. You've already ruled out the obvious physical culprits: caffeine late in the day, alcohol before bed, a warm bedroom, early-morning noise.
This is where CBN has the strongest research fit. Our CBN gummies are formulated for this scenario.
When CBD Is the Better Choice
You can't fall asleep because your brain won't shut off. Tomorrow's to-do list. A conversation from earlier in the day. General low-grade stress. Anxiety keeping you awake, not a physical sleep problem.
CBD has more research behind it on the anxiety angle. Our CBD gummies for sleep include sleep-focused formulations worth looking at.
When to Combine Both
You have both problems. Trouble falling asleep and trouble staying asleep. A combination product, or a CBD product taken alongside a CBN product, gives you both mechanisms. If cost matters, buying one combination gummy is usually cheaper than stacking two separate products.
Start with the recommended serving size on the label. Give it at least a week of consistent nightly use before deciding what's working. Sleep changes aren't always obvious on night one, and one bad night doesn't mean the product failed. Real patterns show up over several nights of consistent use.
Why Product Quality Matters for Sleep Cannabinoids
Here's the part we have strong opinions about, because we grow the hemp that goes into our products.
The CBN and CBD inside your gummy are only as clean as the hemp flower they came from. Hemp is what's called a bioaccumulator. It pulls whatever is in the soil up into the plant. That's fine when the soil is clean. It's a problem when the soil has pesticide residues, heavy metal buildup, or other contaminants.
Our farm in Wilmore, Kentucky holds USDA Organic certification. That's a federal audit of soil, inputs, and growing practices, not a self-awarded marketing badge. USDA Organic inspectors come on the farm, review records, and audit inputs every year. Every batch that leaves the farm is third-party lab tested for cannabinoid content, heavy metals, pesticides, microbials, and residual solvents. Those COAs are public. You can look them up by batch number on the product label.
If you're taking something every night to sleep, it's worth knowing where it came from. A lot of the CBN on the market is sourced from bulk isolate with zero farm-level transparency. Ours comes from hemp we grew in Kentucky soil we've been farming since 2018.
