## Overview

Cannabigerol (CBG) is a non-psychoactive cannabinoid that acts as a partial agonist of CB1 and CB2 receptors while modulating TRPM8 and α2-adrenergic receptors. CBG demonstrates [neuroprotective](/ingredients/condition/cognitive), [anti-inflammatory](/ingredients/condition/inflammation), and intraocular pressure-reducing properties through multiple molecular pathways.

## Health Benefits

- Supports neuroprotection and brain health by promoting the growth of new brain cells, potentially reducing the risk of neurodegenerative diseases. - May reduce inflammation and pain by inhibiting [inflammatory pathway](/ingredients/condition/inflammation)s, offering relief for chronic pain sufferers. - Promotes eye health by reducing intraocular pressure, which can help prevent glaucoma. - Enhances mood and [mental clarity](/ingredients/condition/cognitive) by interacting with [serotonin](/ingredients/condition/mood) receptors, leading to improved emotional well-being. - Supports [digestive health](/ingredients/condition/gut-health) by modulating gut microbiota, which can improve nutrient absorption and gut function. - Boosts [immune system](/ingredients/condition/immune-support) function by enhancing the body's natural defense mechanisms, helping to ward off illnesses. - Promotes skin health by reducing inflammation and promoting [collagen production](/ingredients/condition/skin-health), leading to healthier, more resilient skin.

## Mechanism of Action

CBG acts as a weak partial agonist of CB1 and CB2 cannabinoid receptors while antagonizing α2-adrenergic receptors and activating TRPM8 channels. It inhibits the reuptake of anandamide and modulates adenosine A2A receptors, contributing to its [neuroprotective effect](/ingredients/condition/cognitive)s. CBG also interacts with 5-HT1A [serotonin](/ingredients/condition/mood) receptors and blocks calcium channels, which underlies its [anti-inflammatory](/ingredients/condition/inflammation) and analgesic properties.

## Clinical Summary

Human clinical research on CBG remains limited, with most evidence derived from preclinical studies and animal models. A small pilot study (n=127) found CBG effective for anxiety, chronic pain, and sleep issues, with 73.9% reporting improved [sleep quality](/ingredients/condition/sleep). Animal studies demonstrate significant [neuroprotective effect](/ingredients/condition/cognitive)s in Huntington's disease models and [inflammatory](/ingredients/condition/inflammation) bowel disease, with dosages ranging from 1-10 mg/kg showing efficacy. Current evidence is promising but requires larger randomized controlled trials to establish therapeutic dosing and long-term safety profiles.

## Nutritional Profile

- Contains cannabinoids that interact with the endocannabinoid system.
- Non-psychoactive and found in small quantities in cannabis.
- Often used in combination with other cannabinoids for enhanced effects.

## Dosage & Preparation

Common dosages range from 5 mg to 50 mg per day. Consult a healthcare provider before use.

## Safety & Drug Interactions

CBG appears well-tolerated in preliminary studies, with mild side effects including dry mouth, drowsiness, and increased appetite reported at higher doses. CBG may interact with cytochrome P450 enzymes, potentially affecting [metabolism](/ingredients/condition/weight-management) of medications including blood thinners and seizure medications. No specific contraindications have been established, though caution is advised for individuals taking CNS depressants due to potential additive sedative effects. Safety during pregnancy and breastfeeding has not been established, and use should be avoided without medical supervision.

## Scientific Research

Preliminary studies, including in vitro and animal research, suggest potential benefits in neuroprotection and [inflammation](/ingredients/condition/inflammation). Human trials are limited but ongoing.

## Historical & Cultural Context

CBG was identified in the 1960s but has gained attention recently as research explores its unique benefits compared to other cannabinoids.

## Synergistic Combinations

CBD, Lutein, Omega-3

## Frequently Asked Questions

### What is the difference between CBG and CBD?

CBG acts as a partial agonist of CB1 and CB2 receptors while CBD has minimal direct receptor binding and primarily works through indirect mechanisms. CBG is considered the 'mother cannabinoid' as it's the precursor to CBD, THC, and other cannabinoids, and typically shows stronger effects on eye pressure reduction.

### How much CBG should I take daily?

Clinical dosing guidelines for CBG are not yet established due to limited human studies. Preliminary research suggests doses between 2.5-15mg may be effective, though individual responses vary significantly. Start with the lowest possible dose and consult a healthcare provider familiar with cannabinoid therapy.

### Does CBG show up on drug tests?

Pure CBG typically does not trigger positive results on standard THC drug tests, as these tests detect THC metabolites, not CBG. However, full-spectrum CBG products may contain trace amounts of THC that could potentially cause positive results. Choose isolate or broad-spectrum products if drug testing is a concern.

### Can CBG help with glaucoma?

Animal studies show CBG significantly reduces intraocular pressure, a key factor in glaucoma progression, through activation of CB1 receptors in eye tissues. CBG demonstrated greater pressure-reducing effects than THC in some studies, lasting 4-6 hours after administration. However, human clinical trials are needed to confirm therapeutic efficacy.

### Is CBG legal in all states?

CBG derived from hemp containing less than 0.3% THC is federally legal under the 2018 Farm Bill in the United States. However, state laws vary regarding cannabinoid products, and some states have specific restrictions on CBG or require it to be sold only through licensed dispensaries. Check your local and state regulations before purchasing.

### Does CBG interact with common medications?

CBG may interact with medications metabolized by the cytochrome P450 enzyme system, similar to CBD, potentially affecting blood thinners, antiseizure drugs, and immunosuppressants. If you are taking prescription medications, consult with a healthcare provider before adding CBG to your regimen to avoid potential interactions or reduced medication efficacy.

### What is the most bioavailable form of CBG?

Full-spectrum hemp extracts containing CBG typically offer better bioavailability than isolated CBG due to the entourage effect, where other cannabinoids and terpenes enhance absorption and efficacy. Sublingual tinctures and soft-gel capsules with added lipids (such as MCT oil) generally provide superior bioavailability compared to water-soluble formulations.

### Who benefits most from CBG supplementation?

Individuals seeking neuroprotection, those managing chronic pain or inflammation, and people interested in cognitive support may benefit most from CBG supplementation. Additionally, those with early-stage eye health concerns or seeking mood and mental clarity enhancement are potential candidates, though results vary individually and clinical evidence is still emerging.
