In short: Taking CBD oil under your tongue (sublingually) is the fastest and most efficient oral method. Holding the oil for 60-90 seconds allows CBD to absorb directly through the mucous membranes into your bloodstream, bypassing the digestive system. This means faster onset (15-30 minutes vs 60-90 for edibles) and higher bioavailability — more of the CBD you take actually reaches your system.
CBD oil has become a popular wellness product. Among the various methods of consuming CBD, taking it sublingually—under the tongue—stands out for its efficiency and convenience. This article explains how sublingual CBD oil works, how to use it, and what to consider when adding it to your routine.

1. What is CBD Oil? Understanding the Basics
What is CBD Oil?
CBD oil is a natural extract derived from the hemp plant, without the psychoactive effects associated with THC, the compound found in cannabis. The oil contains cannabidiol (CBD), which interacts with the body’s endocannabinoid system. Typically, CBD oil is combined with a carrier oil, such as MCT oil or hemp seed oil, to enhance its absorption in the body.
How is CBD Oil Made?
The production of CBD oil involves extracting CBD from the flowers, leaves, and stalks of the hemp plant. Several methods of extraction exist, but CO2 extraction, which we do at unspun, is considered the gold standard due to its ability to produce a pure, high-quality product without harmful residues [2]. After extraction, the CBD is diluted with a carrier oil, resulting in a tincture that can be used sublingually or added to food and beverages.
Sublingual CBD bypasses your digestive system entirely.
The Types of CBD Oil Available
CBD oil comes in various forms. Full-spectrum CBD oil contains all the cannabinoids, terpenes, and other compounds found in hemp, creating an "entourage effect" in which the compounds work together [3]. Broad-spectrum CBD oil is similar but has had almost all of the THC removed, making it a suitable choice for those who wish to avoid THC. Finally, CBD isolate is the purest form, containing only CBD without any other compounds. Your choice depends on your personal preferences.
2. Why Take CBD Oil Under the Tongue?
What Does Sublingual Administration Mean?
Sublingual administration refers to placing a few drops of CBD oil under your tongue and holding it there for 60 seconds before swallowing. This method allows the CBD to be absorbed directly into the bloodstream through the mucous membranes under the tongue, bypassing the digestive system and liver [4]. By avoiding these processes, sublingual administration ensures that more CBD enters the bloodstream quickly and efficiently.

How Does Sublingual CBD Work?
When you take CBD oil sublingually, it interacts directly with the sublingual glands, which are rich in blood vessels. This allows the CBD to be absorbed almost immediately into the bloodstream, faster than other methods, such as swallowing CBD capsules or edibles, which need to pass through the digestive system first [5].
Why is it More Effective Than Other Methods?
In contrast, when you ingest CBD orally (by simply swallowing it), much of the CBD is broken down by your liver before it can enter your bloodstream, reducing the amount absorbed [6]. This makes sublingual administration a preferred choice for those who want a higher proportion of the CBD to reach the bloodstream.
3. How Long Does it Take for CBD Oil to Work Under the Tongue?
What is the Absorption Time?
One of the primary advantages of taking CBD oil under your tongue is its rapid absorption. Typically, users can begin to notice the effects within 15 to 30 minutes. This quick onset is due to the direct absorption of CBD into the bloodstream through the mucous membranes under the tongue, bypassing the digestive system [4]. The fast absorption time makes this method particularly convenient.
How Long Do the Effects Last?
The duration of the effects can vary depending on several factors. On average, the effects last between 4 to 6 hours, although this can be influenced by the dosage, the concentration of CBD in the oil, and individual factors such as metabolism [5]. Regular users might find that the effects last longer as CBD builds up in their system over time.
Factors Affecting the Onset of Effects
Several factors can influence how quickly you notice the effects of CBD oil taken under the tongue. These include the strength of the oil, your individual metabolism, and whether you have eaten recently. Additionally, the length of time you hold the oil under your tongue before swallowing can significantly impact absorption. Holding it for at least 60 seconds allows for maximum absorption through the sublingual glands, optimising the speed and efficiency of the CBD [6].
4. The Advantages of Taking CBD Oil Under Your Tongue
Fast Absorption
Taking CBD oil under your tongue is one of the fastest ways for it to reach your bloodstream. The rich network of blood vessels under the tongue allows for rapid absorption, bypassing the digestive system. This direct absorption means CBD enters the bloodstream much more quickly than with other methods, such as CBD gummies or capsules [4].
Enhanced Bioavailability for Maximum Impact
Bioavailability refers to the proportion of a substance that enters the bloodstream when introduced into the body. Sublingual administration significantly enhances the bioavailability of CBD compared to oral ingestion. When taken sublingually, a higher percentage of the CBD is absorbed directly into the bloodstream [6]. This increased bioavailability means that users can take in the same amount of CBD with a smaller dose, making it a more cost-effective option as well.
Convenience and Ease of Use
Sublingual administration is not only efficient but also straightforward. You don’t need any special equipment or preparation—just place the drops under your tongue and hold them there for at least 30 seconds and up to 1 minute if you find it easy. This method is excellent for when you are at home. The simplicity of this method, combined with its efficiency, makes it a preferred choice for many CBD users [4]. Granted, holding oil under your tongue for a minute might feel a bit strange—just try not to chat or drink during that time, unless you're a fan of unusual conversations!
5. How Much CBD Oil Should You Take Under Your Tongue?
Determining the Right Dosage
Finding the correct dosage of CBD oil for sublingual use can vary depending on several factors, including your body weight and your individual tolerance to CBD. A common recommendation is to start with a low dose, such as 10-20 mg of CBD per day, and gradually adjust it. Starting slow is especially important for those new to CBD, as it allows you to monitor how your body responds to the supplement [1].
Factors Influencing Dosage Needs
Several factors can influence your ideal dosage of sublingual CBD oil. These include your metabolism and the concentration of the CBD oil. Additionally, personal factors such as age, weight, and overall health can play a role in determining the appropriate dose. It’s a good idea to monitor how your body responds to CBD and adjust the dosage as needed [1].
Tips for Finding Your Ideal Dose
To find your ideal dosage of CBD oil, consider keeping a journal to track your usage. Start with a low dose and gradually adjust it, noting how you respond. Consulting with a healthcare provider is also recommended, especially if you are taking other medications or have underlying health conditions [3]. Finding the right dose might take some experimentation.
6. What are the Side Effects of Taking CBD Oil Under the Tongue?
Common Side Effects to Watch For
While CBD is generally well-tolerated, some users may experience mild side effects when taking CBD oil under the tongue. Common side effects include dry mouth, dizziness, and changes in appetite. These effects are usually temporary and subside as your body adjusts to the CBD. It’s important to start with a low dose to minimise the risk of side effects and to monitor how your body responds as you gradually increase the dosage [7].
How to Minimise Potential Side Effects
To minimise potential side effects when taking CBD oil sublingually, it is advisable to start with a low dose and gradually adjust it as needed. Choosing a high-quality CBD oil that is free from contaminants is crucial, as low-quality products may increase the risk of adverse reactions. Staying hydrated and taking CBD oil with food can also help reduce side effects like dry mouth and dizziness [7]. Additionally, holding the oil under your tongue for the recommended 60 seconds before swallowing can improve absorption.
Who Should Avoid Taking CBD Oil?
While CBD oil is generally safe for most people, certain individuals should exercise caution or avoid using it altogether. Pregnant or breastfeeding women, individuals with certain medical conditions, and those taking medications that interact with CBD should consult with a healthcare provider before using CBD oil. It’s important to discuss your health status and any potential risks with a professional to ensure safe use. For example, CBD can interact with medications metabolised by the liver's cytochrome P450 enzyme system, potentially altering their effects [8].
7. Choosing the Best CBD Oil for Sublingual Use
What to Look for in a Quality CBD Oil
When selecting a CBD oil for sublingual use, it’s important to consider several key factors, including the purity, potency, and source of the hemp from which the CBD is derived. First, opt for products made from organically grown hemp, as these are less likely to contain harmful pesticides, heavy metals, or other contaminants. The method of extraction is also crucial; CO2 extraction is often considered the best method because it produces a pure and potent product without leaving behind harmful solvents [2].
Additionally, check whether the product is full-spectrum, broad-spectrum, or an isolate. Full-spectrum CBD oil contains a range of cannabinoids and terpenes that work together, known as the "entourage effect" [3]. Broad-spectrum oil is similar but with very low THC content, making it a good choice for those who want to avoid this psychoactive component. CBD isolate, on the other hand, contains only pure CBD, without any other cannabinoids or terpenes. Your choice will depend on your specific needs and preferences.
The Importance of Third-Party Testing
Third-party testing is a critical aspect to consider when choosing a CBD oil. Reputable brands like unspun will have their products tested by independent labs to verify their potency and purity, and you can find our results here. These tests check for the presence of contaminants such as heavy metals, pesticides, and solvents and also confirm the concentration of CBD and other cannabinoids in the product. Always look for products that provide access to these third-party lab results, which are often available on the brand's website or by request. This transparency ensures that you are getting a high-quality product [9].
How to Select the Right CBD Product for Your Needs
Selecting the right CBD product involves considering your specific preferences. If you are looking for the full range of compounds from the hemp plant, including the combined contribution of various cannabinoids, full-spectrum CBD oil might be the best option [3]. However, if you wish to avoid any trace of THC, broad-spectrum or CBD isolate products would be more suitable. Other factors to consider include the flavour of the oil, the concentration of CBD, and any additional ingredients such as added terpenes or flavourings.
It’s also important to consider the concentration of CBD in the oil. Higher concentrations are generally more potent and can be more economical over time, but they may not be necessary for everyone. Starting with a lower concentration and gradually adjusting as needed can help you find the right balance for your needs [1].
8. FAQs About Taking CBD Oil Under Your Tongue
Is Sublingual CBD Oil Safe?
Yes, sublingual CBD oil is generally considered safe for most people. Research shows that CBD is well-tolerated, even in high doses, with few serious side effects [7]. However, as with any supplement, it’s important to use high-quality products and adhere to recommended dosing guidelines. Consulting with a healthcare provider before starting CBD is particularly important if you have underlying health conditions or are taking other medications, as CBD can interact with certain drugs [8].
Can You Take CBD Oil with Other Medications?
CBD oil can interact with certain medications, particularly those that are metabolised by the liver’s cytochrome P450 enzyme system. This includes common medications such as blood thinners, antihistamines, and some antidepressants [8]. These interactions can affect how your body processes certain medications, potentially leading to increased side effects or reduced effectiveness of the medication. If you are taking prescription medications, it is crucial to consult with your healthcare provider before adding CBD oil to your routine to avoid potential interactions.
How Do You Store CBD Oil for Best Results?
To preserve the potency and freshness of CBD oil, it should be stored in a cool, dark place away from direct sunlight and heat. Exposure to light and heat can degrade the cannabinoids and reduce the quality of the oil over time. While refrigeration is not necessary, it can help extend the shelf life of the product, particularly if you do not use it regularly. Always ensure that the bottle is tightly sealed to prevent air exposure, which can also affect the quality of the oil [10].
