How does sublingual CBD oil work?

- Advertisement -

If you’re fairly new to CBD, you’ve probably started seeing the word “under the tongue.” While it is a somewhat fancy word, it only describes a simple process of administering a CBD oil tincture.

Sublingual is a common term that describes the best way to consume CBD oil. The process contains only a few steps, and if you follow these steps, you should feel the effects of CBD relatively quickly, and for a longer period of time.

Before digging into how sublingual CBD oil works, CBD School Wants to create a better foundation for your knowledge of CBD.

What is CBD oil?

read: What is CBD (Cannabidiol)?

CBD oil comes in a tincture bottle and is one of the most popular CBD products on the market. CBD, or cannabidiol, is Hemp extractand then Filled with carrier oil To produce CBD oil.

Some brands will add additional ingredients to CBD oil to either target a specific condition the CBD oil is supposed to help, such as adding melatonin to the CBD oil being produced. Helping someone with sleep problemsOr, sometimes the brand adds a natural or artificial flavor to the process so that the CBD oil has a more desirable flavor, like peppermint.

How does sublingual CBD oil work?

As mentioned above, sublingual administration refers to the process of consuming CBD (or medication or supplement) by placing CBD under your tongue and allowing the oil to be absorbed.

Under your tongue, the ventral (abdominal) surface is a membrane called the sublingual mucosa.

This membrane allows whatever is absorbed to “bypass first-pass metabolism, thus facilitating rapid absorption of the drug into the systemic circulation.”1

By bypassing first-pass metabolism, CBD is not only able to retain a higher concentration of its benefits but also has a faster time to reach the systemic circulation using the vasculature.

Steps to take sublingual CBD

Consuming sublingual CBD is fairly easy if you follow these steps:

  1. First, find out how much CBD dosage is right for you. common CBD Dosage Between .15 mg – .25 mg of body weight.
  2. Once you have determined how much CBD oil is right for you, press the top of the dropper when the tip is submerged in the CBD oil tincture bottle.
  3. Place the tip of the dropper under your tongue and press the top of the dropper to allow the CBD oil to drain under your tongue. You will find that there is a small pocket under your tongue where the CBD oil will remain.
  4. Allow the CBD oil to absorb into the membrane in an effort to prevent the oil from being ingested.
  5. Wait 1-2 minutes while the CBD oil is absorbed under your tongue.
  6. When you feel that the CBD oil has been mostly absorbed, you can swallow it.
  7. Once you have completed these steps, you can drink or eat freely, the CBD oil has now been absorbed and you should feel the effects within 15 minutes.

Why is taking CBD sublingually beneficial

Consuming CBD oil under the tongue has few benefits to consuming CBD in a mixed drink or swallowing CBD directly from a dropper.

Faster CBD Effects

Because of the first-pass metabolism, CBD does not have to follow the common pathway that food does. CBD oil passes into the bloodstream largely because it bypasses the digestive system and liver.

Increased bioavailability

Since CBD oil goes directly into the bloodstream, the rate of bioavailability is greatly increased. Anytime a substance is ingested and makes its way to the liver, the substance is broken down reducing its bioavailability and removing many of the health benefits of the substance (in this case CBD) that it provides you.

CBD Effects Longer

Since CBD oil goes directly into the bloodstream, the CBD will stay in your body for a longer period providing you the benefits for a longer period of time.

Is it okay to swallow?

If you accidentally swallow some of the CBD oil that is being absorbed, don’t worry because the CBD will still find its way into your bloodstream. However, you will lose some of the bioavailability, and the potential beneficial effects may take a little longer.

It’s inevitable to swallow some CBD oil, so relax all is well.
