Keep in mind that you can't use any type of product for sublingual delivery. Instead, you have to rely on CBD oil tincture. CBD edibles have to pass through your digestive tract and will not have contact with the sublingual gland, while topical CBD items are primarily used for the skin. You also have inhaled CBD that doesn’t get into contact with this gland.

In this article, we will analyze some of the main reasons to use CBD sublingual drops and what kind of absorption you can expect.

How do you administer CBD oil sublingually?

A lot of people think that sublingual delivery is the same as oral consumption, but there are some differences. When you place a sublingual CBD substance under your tongue, it starts interacting with the previously mentioned gland. As it gets dissolved, it will go directly into your bloodstream, thus avoiding the stomach and its juices. Because of that, you can achieve greater CBD bioavailability.

When you use a sublingual tincture, you will need to hold it in your mouth, under your tongue, for a minute or two. During this time, you can swirl it a little bit. This would give your body enough time to process the substance and absorb it. After the two minutes have passed, you can swallow the rest of CBD oil. This is different from oral administration, where you would directly swallow the tincture without passing it through your mouth.

It is believed that edibles, such as CBD gummies and CBD capsules, have a utilization rate of 10% to 20%. These figures can go as low as 4%. On the other hand, the sublingual method may range between 13% and 19%, but there were also cases where it went to 35%. So, by simply changing the way you use sublingual CBD oil, you can achieve much better results.

Sublingual bioavailability is the reason why CBD sublingual oil trumps other products in terms of price and effect. However, the results may vary based on the administration method and the product that you're using. For example, edibles will take a while to reach your bloodstream, but once they're there, these products will provide an effect that will last for several hours. Inhaled CBD products will reach your bloodstream almost instantaneously, but they will remain within the body for a short while. So, there are lots of things you need to consider before making a purchasing decision.

How should CBD sublingual oil work?

Our body has numerous endocannabinoid receptors. They are a part of a larger endocannabinoid system. These receptors can be stimulated with CBD, and once this substance is introduced into the body, it can improve the way the endocannabinoid system works.

We don’t know everything about the endocannabinoid system. But, it might be important for the regulation of processes such as sleep, mood, regeneration, protection, and so on. One of the main reasons why people use CBD oil is to improve their sleeping patterns and to reduce stress levels. At this moment, CBD tinctures are mainly regarded as a wellness product, and they shouldn't replace prescription medication.

When used sublingually, CBD oil is meant to boost internal processes such as mood, sleep, protection, etc. But, you can also use the oil topically. When you apply it to your skin, its potential benefits change. Now, the substance might reduce muscle soreness while also addressing minor skin issues.

What is faster: sublingual or oral?

According to a study, sublingual CBD oil will reach its peak efficiency after 2, 3 minutes. After that, your body will slowly start filtrating the substance, and after 10 to 15 minutes, all of its therapeutic properties will be gone. People usually counter this by reusing the substance throughout the day. Whether we're talking about medical marijuana or hemp, oral cannabis products have to go through the stomach, which prolongs the whole process. You might feel the first improvements after 30 minutes to an hour. However, the benefits might last for several hours.

The best thing about CBD tinctures is that they act rather quickly. They are very good for people who require quick relief. Although these benefits will not be instantaneous, they will be much faster compared to those provided by edibles. While vapes may provide a similar effect, they are not ideal for every situation. Keep in mind that medicinal hemp oil can also be used for surface issues and can potentially address muscle and skin issues. But, most people will use other topical products for this particular function, such as CBD creams and CBD lotions.

One of the biggest advantages of sublingual consumption is that CBD will only be affected by salivary enzymes. They might lead to degradation of the substance, but besides these enzymes, there is nothing else that would reduce CBD bioavailability. On the other hand, edibles have to deal with the whole gastrointestinal tract. As the cannabinoids pass through it, they will be broken down by the chemicals resulting in a minor percentage of the product entering the bloodstream.

How much CBD should you take during sublingual administration?

Similar to prescription medication, you have to consider the dose before using sublingual CBD. There are several factors that will affect the optimal quantity you need to take during a day. The most important considerations include body weight, tolerance, concentration, condition, and age.

The biggest issue with dosing is the regulation and lack of data. Until recently, the cannabis plant was completely illegal. Although we've been using industrial hemp for quite a while, the hemp plant was often restricted in some way or another. Even though the medical hemp plant is now available to a larger population, we need to learn more about these products. They are not used for medical treatments but more as wellness substances.

Most companies rely on body weight as the main factor for determining dosage. Based on it, lighter people will require 10mg of CBD oil, while heavier individuals may need 25mg and more. This also has to be tweaked based on tolerance. However, if you’re a first time user, tolerance will not play a major role for you.

The general suggestion is to start with a minimal dosage according to your weight. Then, you can tweak it based on the results. Bear in mind that a lot of people will need a week or so to feel the first improvements. Then again, it depends on the condition that you're trying to address. Some people will never feel an improvement when using sublingual CBD products; the potential benefits can vary significantly from individual to individual.

What are the main types of CBD sublingual items?

There are a few categories of CBD tinctures:

Full spectrum CBD

Full spectrum CBD oil is the most common type of medical hemp oil. It is directly extracted from the plant, and it has all the cannabinoids and terpenes as the hemp itself. Among others, it has THC, which is why some users prefer other types of items.

Broad spectrum CBD

Broad spectrum CBD oil doesn't have THC. Besides that, it has all the other substances as full spectrum sublingual tinctures.

CBD isolates

CBD isolates focus on one particular substance. As the name implies, they will only have cannabidiol. However, isolates can be made from any cannabinoid found within the hemp plant. The main reason why you should use these products is that you want to focus on the potential benefits of CBD while avoiding other chemical compounds. Needless to say, isolates don't have THC.

It is really hard to tell which one of these product categories is the best. Each one of them has a set of traits, and perhaps it's best to try each one of them before deciding what you want to use in the long run.

Benefits of sublingual CBD products

Although the main emphasis is on bioavailability, there are some other reasons why you should use sublingual CBD oil:


These products are much easier to dose. Whenever you take a dropper of CBD oil, you can rest assured that your body took this precise dosage while also accounting for the loss of bioavailability. Other products can be a bit trickier. For example, there might be some variations in terms of substance loss when a product passes through your gastrointestinal tract. Vaping CBD may also provide different results due to your inhalation technique.


CBD oil is the most popular product on the cannabis market. Things such as CBD isolates can be found almost at every corner. Even if an online store specializes in a particular hemp item, they will likely still have sublingual oil. This makes it easier not only to purchase but purchase a product with specific characteristics and potency.


You can use cannabidiol oil directly by simply squeezing it into your mouth. You don't need additional equipment, which is sometimes the case with other items. Furthermore, other substances may lead to additional side effects such as stomach cramping when you use edibles or breathing issues with vapes.


While edibles are probably the most convenient products, sublingual substances are not far behind them. They can be used on the go, and you can place them in your purse or backpack.

Store Availability

Due to the fact that CBD oil can be found almost anywhere, its price is usually lower compared to some other items. If we also account for savings based on bioavailability, it soon becomes clear that sublingual products can save you a lot of money over a prolonged period of time.
