CBN for Sleep: What the Double-Blind Clinical Study Actually Found
Jake Jones
If you've ever reached for a Gold Naturals Sleep product and wondered what's actually making it work, the answer goes deeper than CBD alone. Our Sleep tinctures, soft gels, and gummies are formulated with CBN — cannabinol — a naturally occurring cannabinoid that has emerged as one of the most promising compounds for supporting healthy sleep.
Here's what the science says, why we use CBN, and what a landmark clinical study revealed about its effectiveness.

What Is CBN?
CBN is a minor cannabinoid that forms naturally as THC ages and oxidizes in the hemp plant. Unlike THC, CBN is non-intoxicating at the concentrations found in hemp-derived products. It was actually one of the first cannabinoids ever isolated — predating even CBD in the scientific literature — but only recently has serious research attention turned to its sleep-specific properties.
CBN interacts with both CB1 and CB2 receptors in the body's endocannabinoid system (ECS), as well as with non-ECS pathways involved in pain modulation and circadian rhythm regulation. This multi-pathway mechanism is what makes CBN particularly interesting for sleep researchers.
The Peer-Reviewed Evidence: A 3-Group Double-Blind Study
One of the most rigorous studies examining CBN for sleep was a randomized, double-blind, placebo-controlled trial — the gold standard in clinical research. The study divided participants into three groups:
- Group 1: CBD alone
- Group 2: CBN + CBD combination
- Group 3: Placebo
The results were striking. Participants in the CBN + CBD combination group reported significantly greater improvements in:
- Time to fall asleep (sleep latency)
- Total sleep duration
- Sleep quality scores
- Daytime alertness and reduced grogginess
Notably, CBD alone outperformed placebo — but the CBN + CBD combination consistently outperformed CBD alone. This points to the entourage effect: cannabinoids working synergistically together are more effective than any single compound in isolation.
"The combination of CBN and CBD demonstrated a statistically significant improvement in sleep quality compared to CBD alone and placebo, suggesting a synergistic cannabinoid effect on sleep-related outcomes."

How Gold Naturals Formulates CBN Into Our Sleep Products
Gold Naturals Sleep products aren't just CBD with a "sleep" label slapped on. Our formulas are built around the science:
- Sleep Tincture: Full-spectrum hemp oil with CBN and natural terpenes known to support relaxation (including myrcene and linalool). Taken sublingually for faster absorption — typically felt within 15–30 minutes.
- Sleep Soft Gels: Precise, consistent doses of CBN + CBD in a softgel shell for slower, sustained release throughout the night. Ideal for people who wake up in the early morning hours.
- Sleep Gummies: CBN + CBD in a delicious, easy-dose format. Each gummy delivers a measured amount with no guesswork.
All three products are third-party lab tested and Certificates of Analysis are publicly available on our COA page.
What the Research Means for You
If you've tried CBD for sleep and felt it "sort of" worked but not consistently — the missing piece may be CBN. The clinical evidence supports what many Gold Naturals customers already experience: the combination simply works better.
CBN is not a sedative. It doesn't knock you out. Instead, it appears to help your body's own sleep systems — particularly the ECS — do what they're designed to do: wind down, reduce nighttime cortisol, and support the deeper stages of sleep your body needs to recover.
