Chemical Forms

Recommended
  • CBG isolate
  • Hemp extract standardized for CBG
  • Full-spectrum CBG oil
Avoid
  • Unverified hemp extracts (inconsistent potency, potential THC contamination)
Expert Note

Isolates give the most predictable dose and avoid THC. Standardized extracts can preserve other cannabinoids and terpenes, but product content varies, so a third-party COA matters.

Protocol

Amount
5-25 mg
Frequency
Once or twice daily
When
With food to improve absorption and reduce stomach upset; evening if using for sleep.

Condition-Based Dosing

General wellness exploration
Start with 5-10 mg once daily and titrate slowly.
Anxiety or sleep support (observational use)
10-20 mg in the evening.

Safety & Limits

Upper Safe Limit
No established UL; ~50 mg/day is the highest commonly studied daily dose, but long-term safety above this is unclear.
Cycling
Safe for continuous use

Contraindications

Pregnancy or breastfeeding — insufficient safety data
Liver disease — potential CYP450 interaction risk
History of psychosis or schizophrenia — theoretical risk with cannabinoids even if non-intoxicating
Children and adolescents — insufficient safety data

Synergies

CBD

CBG and CBD may interact with complementary endocannabinoid targets, though human synergy trials are lacking.

Avoid Combining With

  • ✕Alcohol and other CNS depressants (may amplify drowsiness and impairment)
  • ✕Prescription drugs metabolized by CYP2C9/CYP3A4 (potential interaction — consult a pharmacist)
