CBD vs CBG vs CBN – The Complete Guide to Cannabinoids
What is CBD, what is CBG, and what is CBN? Which cannabinoid is best for sleep, stress, pain, or inflammation? We explain the differences.
Cannabis contains over 100 different cannabinoids, but only a few have been studied in detail. The three most important for health applications are CBD, CBG, and CBN.
What Is the Endocannabinoid System (ECS)?
The ECS is a biological system present in all mammals. It regulates sleep, mood, pain, appetite, immunity, and inflammation. Cannabinoids from hemp act on this system.
CBD (Cannabidiol) – The Most Researched Cannabinoid
●Anxiety and stress – 79.2% of participants report reduced anxiety
●Pain and inflammation – CBD inhibits COX-2 enzyme (same mechanism as ibuprofen)
●Epilepsy – Epidiolex (pure CBD) is the only FDA-approved CBD medication
●Sleep – 66.7% report improved sleep
CBG (Cannabigerol) – The "Stem Cell" of Cannabinoids
CBG is called the "stem cell" because all other cannabinoids are created from CBGA. In the mature plant, it's very rare (below 1%). CBG directly binds to CB1 and CB2 receptors.
●Anti-inflammatory – particularly effective for intestinal inflammation (Crohn's, colitis)
●Antibacterial – effective against MRSA
●Neuroprotective – protects nerve cells
CBN (Cannabinol) – The Sleep Cannabinoid
CBN is formed through THC degradation. It's mildly psychoactive and primarily known for its sedative effect.
●Sleep and sedation – CBN is the strongest natural sedative among cannabinoids
●Pain – CBN activates capsaicin receptors (TRPV2)

Which Cannabinoid Is Right for You?
●For ANXIETY AND STRESS → CBD (5–20mg daily, under the tongue)
●For INSOMNIA → CBN (or CBD in evening as alternative)
●For DIGESTIVE ISSUES → CBG (anti-inflammatory for the gut)
●For GENERAL WELLNESS → Full Spectrum CBD oil (entourage effect)
