Health & safety: This page is educational, not medical advice. CBD can cause side effects and interact with medications. FDA advises against CBD/THC use during pregnancy or breastfeeding.

What these names mean

CBD (cannabidiol), CBN (cannabinol) and CBG (cannabigerol) are different cannabinoids found in or derived from cannabis/hemp. Commercial products may contain one cannabinoid or combine several in gummies, oils, capsules and other formats.

What product labels can—and cannot—tell you

A label can tell you the stated amount and ingredients. A COA can provide laboratory measurements for a tested batch. Neither proves that an unapproved consumer product treats a disease or will produce a specific result for you.

CBD

CBD is the most familiar non-intoxicating cannabinoid in mainstream hemp products. FDA emphasizes that non-prescription CBD products have important safety unknowns and may interact with medications; it has approved one prescription CBD drug for specific seizure disorders.

CBN

CBN is commonly positioned by merchants in nighttime products. Treat claims about sleep or sedation as claims that need evidence rather than as established outcomes for every consumer.

CBG

CBG is commonly marketed in “focus,” “clarity” or daytime-oriented products. The same evidence discipline applies: formulation facts are measurable; promised wellness outcomes should not be assumed.

How this changes shopping

Choose the cannabinoid profile only after deciding what you want to avoid (for example THC), what format is practical, what strength is appropriate to discuss with a healthcare professional, and whether the batch COA supports the label.
