CBG Benefits: What Research Shows About Cannabigerol
CBG Benefits: What Research Shows About Cannabigerol
CBG is the rarest major cannabinoid and the least studied, but the research that exists is promising. Here is what the science says so far, cited directly from peer-reviewed sources.
1. Focus and Mental Clarity
CBG interacts with alpha-2 adrenergic receptors, which regulate norepinephrine, a neurotransmitter directly involved in attention, arousal, and cognitive function. This receptor interaction, combined with CBG's partial agonism at CB1 receptors in the brain, may explain why CBG users frequently report enhanced mental clarity and focused alertness.
When paired with caffeine (as in CBG coffee), these two focus-supporting mechanisms stack: caffeine blocks adenosine for wakefulness while CBG engages adrenergic and cannabinoid pathways for directed attention.
2. Metabolic Support
A March 2026 study published in the British Journal of Pharmacology found that CBG was more effective than CBD at reducing body fat and improving insulin sensitivity. The study examined both cannabinoids for metabolic dysfunction associated with fatty liver disease and found CBG acted through PPARgamma receptors, which regulate fat storage and glucose metabolism.
This is particularly relevant for coffee drinkers: caffeine itself has metabolic effects, and the addition of CBG may provide complementary metabolic support through a completely different pathway.
3. Digestive Comfort
According to the 2024 comprehensive review in Molecules, CBG has demonstrated anti-inflammatory activity in models of intestinal inflammation. For coffee drinkers who experience stomach sensitivity, CBG's potential to reduce gut inflammation could make CBG coffee a more comfortable option than regular coffee.
4. Neuroprotective Properties
Preclinical research has shown CBG may have neuroprotective effects, supporting neuronal health in models of neurodegenerative conditions. The Realm of Caring Foundation's 2026 research review notes that CBG's direct receptor binding (as opposed to CBD's indirect modulation) may provide more targeted neuroprotective activity.
5. Anti-Inflammatory Activity
CBG acts on multiple inflammatory pathways, including TRPV1 and TRPV2 channels. The 2024 Molecules review notes that CBG demonstrates "compelling biological activity" in reducing inflammatory markers across multiple preclinical models.
6. Synergy with CBD (The 1:1 Advantage)
Perhaps the most actionable benefit of CBG is what happens when you combine it with CBD. A 2024 peer-reviewed study found that CBD and CBG in a 1:1 ratio produce synergistic effects, with a measured 6-fold increase in potency compared to predicted additive effects. Buddha Beans formulates all CBG coffee with equal CBD specifically to deliver this synergy.
7. Appetite Regulation
Unlike THC (which is known to stimulate appetite), CBG's effects on appetite are more nuanced. Some research suggests CBG may help regulate appetite without the "munchies" effect, though this area needs more investigation.
Important Context
How to Get CBG Benefits from Coffee
Buddha Beans CBG coffee delivers approximately 7mg CBG and 7mg CBD per cup, the 1:1 ratio used in the synergy research. For a higher dose, our Black Label delivers approximately 12.5mg of each per cup (25mg total cannabinoids). All products are USDA Organic, third-party lab tested, and contain 0% THC.
