Format affects how a serving is measured and used. It does not turn a consumer CBD product into a medicine or prove that it is suitable for you.
Oil, spray, capsule or gummy
An oil usually combines a CBD extract or isolate with a carrier oil. A spray adds a measured pump, while capsules and gummies divide the product into individual units. These differences can make serving calculations more or less straightforward.
Sublingual and buccal are terms for placement under the tongue or against the cheek. They should not be treated as guarantees about absorption or effect.
Compare like with like
Translate every product into milligrams of CBD per suggested serving. Then look at the number of servings, full ingredient list and current batch report. Comparing percentages alone can obscure bottle size and serving instructions.
Consumer product or medicine
A retail CBD product is not an approved treatment simply because it comes in a measured format. The FDA has approved one prescription CBD medicine for specific seizure disorders. That approval does not extend to ordinary oils, gummies or sprays.
Do not use consumer CBD products as substitutes for prescribed treatment. Speak with a pharmacist or clinician about symptoms, medicines and possible interactions.
