It is up to you whether you keep your mouth open and your tongue raised or close your mouth. The important part is that the oil must remain in contact with the membrane under your tongue for the full time.
Since CBD found its way into high street shops and online stores, the choices have improved. You can choose from products such as drops, sprays, capsules and gummies. You can also choose how to take it. CBD can be swallowed, placed under the tongue, vaped, rubbed into your skin or applied rectally.
How do I take CBD under the tongue?
When CBD is in your mouth you may notice an intense, bitter flavour. Because many high-quality oils get the best effects from using more of the hemp plant, they can be intensely grassy and bitter. While unpleasant, this alone won’t do you any harm. A mouthful of water will help with any strong flavours.
1. Stand next to a mirror or ask a friend to help you position the dropper correctly and count out the drops. Once you’ve tried it a couple of times it gets easier and becomes quick and convenient.
Once the time has passed you can swallow any residue that is left in your mouth. This prevents any remaining cannabidiol from being wasted. Because some CBD oils leave a strong earthy taste, many people choose to complete the 90 seconds and then take a large swig of water to wash down any remaining oil.
Sublingual delivery isn’t always a better option for all substances, points out Dr. Birdsall—some B vitamins, for instance, need to be “activated” by the liver in order to do their jobs—but for certain vitamins and medications, it can be a super effective delivery method.
To find out—because there’s been relatively little rigorous research on CBD to date and I’m a skeptic by nature—I reached out to a doctor and a scientist for the 411. As I suspected, this isn’t a topic that has been studied in depth. Yet there is some reason to believe that certain CBD products may truly be more bioavailable when absorbed under the tongue than if taken through food or drink.
After all, if there’s one thing that can be said about the wild west of CBD, it’s that experimentation is key—whether you’re looking for your perfect dose or your perfect delivery method.
Long story short: You may as well try holding your CBD oil or tincture under your tongue before swallowing it—you could find that you feel it working slightly faster. Anecdotally, says Dr. Birdsall, experts recommended that you hold it there for at least 60 seconds. (A word of warning: There will be drool.) Your other option is to try a product that’s specifically created to be absorbed sublingually, like Kin Slips, which are kind of like those breath-freshening films that dissolve in your mouth.
How does this apply to CBD? Surprise, surprise: It’s hard to say. “There has been very little scientific research on the sublingual absorption of CBD,” says Dr. Birdsall. The research that does exist has some inconsistencies, adds Kater, since there are so many factors that affect absorption—such as the quality of the CBD or the pH and consistency of the formulation. Plus, many of these studies focus on formulas that contain both CBD and THC—a psychoactive compound found in cannabis that’s supposed to be absent from CBD-only products—so it’s unclear whether their findings would also apply to a product that contains predominantly CBD.
