While CBN (cannabinol) and CBG (cannabigerol) are known for their calming effects, which support general well-being, CBN is more commonly associated with sleep.
This is interesting because although research is limited, many companies market CBN as a natural sleep aid despite the lack of evidence that shows CBN (on its own) has direct sedative properties.
On the other hand, CBG (cannabigerol) is more known for its potential to support focus and overall wellness, with less direct association with sleep. While both cannabinoids can support relaxation, CBN is generally seen as the go-to option for sleep.
Is CBN Better than CBG for Sleep?
CBN is generally considered better for sleep support. This is because CBN is often associated with promoting relaxation and calm, which can help people wind down before bed.
Let’s look at the differences between the two hemp-derived cannabinoids when considering their impact on sleep.
CBN
You might have heard CBN referred to as the “sleepy cannabinoid,” but recent findings suggest this link between CBN and sleep might not be as clear-cut as initially thought.
CBN itself doesn't have direct sedative properties. Instead, any calming effects are likely due to the entourage effect, where CBN works in combination with other cannabinoids, like THC, and compounds like terpenes to enhance the overall soothing experience.
In this sleep study conducted in 2021, a tablet containing THC and CBN demonstrated an objective and perceived improvement in sleep quality among study participants [1].
When purchasing a CBN product, you will most likely find an additional cannabinoid in the formula. Its synergy with other cannabinoids makes it a cannabinoid team player for relaxation.
So, where did this reputation of CBN as a sleep cannabinoid come from?
One reason may be people feeling drowsy after consuming old cannabis, which has higher CBN levels due to THC breaking down over time. However, experts now believe the drowsiness comes more from other plant compounds changing as cannabis ages, not just CBN alone.
Although there's no solid proof that CBN acts as a sedative, many people find it helpful for deep relaxation and getting better sleep. This is one of the unique aspects of cannabinoids—how they work can vary from person to person, depending on their endocannabinoid system and how it responds to different compounds.
A piece of advice for choosing a CBN product for sleep is to look for a full spectrum product over a CBN isolate. Full spectrum products contain a range of cannabinoids, terpenes, and other beneficial compounds found in the cannabis plant.
This combination might enhance the effects of CBN through the entourage effect, where these compounds work together to promote a more balanced and potentially more effective experience.
CBG
While CBG can offer calming effects, these effects have not yet been tied to improving sleep. Most people use CBG in the daytime for focus and general well-being.
While generally more research is needed to understand CBG’s full scope of benefits and potential usages, a recent study demonstrated CBG’s promising results for anti-inflammatory effects [2]. While there is a connection between inflammation and sleep issues, CBG’s impact on inflammation has not been connected with supporting sleep improvement. 
Would Taking CBN and CBG for Sleep Work?
Taking both CBN and CBG for sleep could be beneficial, but if you're already using a full spectrum CBN product, you might already be getting both cannabinoids.
While CBN is often preferred for relaxation, CBG may also play a supportive role by contributing to overall wellness and balance. Combining the two might help create a more rounded effect, but their benefits can vary.
The key to success with these cannabinoids is how they interact with you. Experimenting with different combinations, like full spectrum products, could give you a better idea of what works best for your sleep routine.
While CBN and CBG may provide sleep support, listening to your body’s signals is important. A healthcare professional can provide individual advice based on your specific needs.
