CBN vs Melatonin: Which Is Better for Sleep?
If you’re struggling to drift off or stay asleep, you’re not alone. The search for effective, natural sleep aids has many people turning to two popular options: CBN (cannabinol) and melatonin. But which one truly delivers better results? In this article, we dive into the research, explore how each works, weigh their benefits and drawbacks, and help you decide which might be the right choice for your unique sleep needs.
How They Work
Melatonin is a hormone produced by the pineal gland that helps regulate your circadian rhythm—the body’s internal clock. As the evening approaches, melatonin signals that it’s time to prepare for sleep. Supplementing with melatonin may help you fall asleep approximately six minutes faster, though it doesn’t meaningfully increase total sleep time (Wikipedia).
CBN, on the other hand, is a lesser-known cannabinoid derived from the breakdown of THC. Unlike THC, CBN doesn’t produce a high, but it is gaining attention for its potential role in promoting sleep and relaxation.
What Does the Research Say?
Melatonin
- Evidence supports melatonin’s modest benefit for sleep onset—speeding time to fall asleep by a few minutes—though overall effectiveness remains limited.
- It’s widely used and generally safe for short-term use, with milder side effects like headache or drowsiness.
- Timing is key: recent studies suggest taking 2–4 mg of melatonin about three hours before bedtime may enhance its effectiveness compared to typical, last-minute dosing.
CBN
- Clinical research is still emerging. A proprietary CBN product showed similar sleep improvements to melatonin, with no significant difference between them.
- Some studies show slight advantages—for example, a 2024 study reported that 50 mg of CBN produced slightly better sleep improvements compared to 4 mg of melatonin.
- However, other trials have found little to no effect from CBN on sleep outcomes .
- Despite this, CBN sales have exploded—especially in California—jumping from 4% to 25% of edible cannabis market share in five years.
CBN vs. Melatonin
| Feature / Factor | Melatonin | CBN |
|---|---|---|
| Mechanism | Signals sleep onset (circadian hormone) | May support sleep quality, relaxation, pain relief, anxiety |
| Effectiveness | Small benefit to sleep onset | Mixed evidence; some slight advantage in small studies |
| Safety Profile | Well-studied; mostly safe short-term | Less established; anecdotal use widespread |
| Availability | OTC widely available | As sleep products, often paired with THC or other cannabinoids |
| Ideal For | Mild insomnia, jet lag, shifting schedules | Those seeking deeper sleep or multi-benefit support |
So, Which Is Better?
If you’re new to sleep supplements and want a safe, well-studied option to help with falling asleep faster—especially in conjunction with better sleep hygiene—melatonin is a solid first choice.
But if you’re exploring sleep aids that may offer additional benefits like anxiety or pain relief, and you’re comfortable with limited clinical backing, CBN—particularly when combined with other cannabinoids—may be worth considering. Just remember the evidence is mixed, and many popular CBN products are blended with THC, potentially altering effects (Wikipedia).
Expert Tips for Better Sleep
- Prioritize sleep hygiene: Consistent schedule, dim evenings, minimized screen time.
- Time your supplements wisely: For melatonin, consider dosing 2–3 hours before bedtime.
- Start with the lowest effective dose. Higher doses don’t necessarily improve results and may carry more side effects.
- Consult a healthcare provider, especially if combining CBN with other medications or using products containing THC.
Final Thoughts
Both melatonin and CBN have roles to play in the evolving sleep-aid landscape. Melatonin is well-understood, mild, and useful for shifting sleep schedules or short-term relief. CBN is the up-and-coming contender—offering broader effects for those searching for a more “whole-body” relaxation approach. But scientific evidence is still playing catch-up with consumer popularity.
