What is CBD oil?
CBD oil is a product made from cannabidiol (CBD), a natural compound found in cannabis plants. Unlike THC, another well-known compound in cannabis, CBD is non-psychoactive and is often used for its potential therapeutic benefits, including alleviating anxiety, pain, and inflammation.

What is sublingual application?
Sublingual application is the method of administering substances by placing them under the tongue – allowing them to be absorbed directly into the bloodstream through the tissues there. This method is often used for medications and supplements, such as CBD oil, because it provides faster and more efficient absorption than oral ingestion.
What is Sublingual CBD Oil?
Sublingual CBD oil is a form of cannabidiol (CBD) oil designed to be administered under the tongue. This method allows the CBD to be absorbed directly into the bloodstream through the sublingual glands, leading to faster and more efficient effects compared to oral ingestion, which requires digestion and metabolisation, as well as other methods available.
Here’s a comparison of the sublingual method with other common methods of CBD administration:
Sublingual CBD
- CBD Oil Absorption Rate: Fast absorption (15-30 minutes).
- Bioavailability: Relatively high due to direct entry into the bloodstream.
- Duration of Effects: Typically lasts 4-6 hours.
- Usage: Easy to dose and adjust; discreet and convenient.
Oral Ingestion (Capsules and edibles)
- Absorption Rate: Slower absorption (30 minutes to 2 hours).
- Bioavailability: Lower, as CBD passes through the digestive system and liver, where some of it is metabolised
- Duration of Effects: Effects can last longer – up to 8 hours or more.
- Usage: Convenient for precise dosing but effects are less immediate and can vary due to digestive factors.
Inhalation (Vaping and smoking)
- Absorption Rate: Very fast absorption (within minutes).
- Bioavailability: High, as CBD enters the bloodstream through the lungs.
- Duration of Effects: Typically lasts 2-3 hours.
- Usage: Provides immediate effects but may be harsh on the lungs and less discreet.
Topical Application (Creams and lotions)
- Absorption Rate: Variable but generally slower.
- Bioavailability: Low, as CBD does not enter the bloodstream but acts on localised areas.
- Duration of Effects: Effects can last several hours, depending on the formulation.
- Usage: Ideal for targeted relief of localised pain or skin conditions.
How Does Sublingual CBD Oil Work?
The science behind sublingual absorption involves the direct uptake of substances through the mucous membranes located under the tongue. Here’s a detailed look at the process and its advantages:
Mechanism of Sublingual Absorption
- Anatomy of the Sublingual Region: The area under the tongue is rich in blood vessels and has a thin mucous membrane, facilitating efficient absorption directly into the bloodstream.
- Cell Membrane Permeability: The thin mucous membrane allows for the rapid passage of substances through the epithelial cells into the capillaries.
- Absorption Pathway: Once placed under the tongue, the substance diffuses through the mucous membrane and enters the extensive network of capillaries. This allows the substance to bypass the digestive system and liver (avoiding first-pass metabolism).
Benefits of Sublingual Absorption
- Rapid Onset of Action: Because the substance enters the bloodstream directly, it can begin to take effect within minutes.
- Higher Bioavailability: Avoiding the digestive tract and liver means more of the substance remains available for use by the body.
- Ease of Administration: It is a simple and non-invasive method – often more convenient than other routes like inhalation or topical application.
Steps of Sublingual Absorption
- Placement: The CBD oil or other substance is placed under the tongue.
- Dissolution: The substance begins to dissolve in the saliva.
- Diffusion: The dissolved substance diffuses through the mucous membrane.
- Entry into Bloodstream: The substance enters the capillaries and then the systemic circulation.
Factors Affecting Sublingual Absorption
- Molecular Size and Lipophilicity: Smaller, lipophilic (fat-soluble) molecules pass through the mucous membranes more easily.
- Formulation: The presence of certain solvents and enhancers in the formulation can improve absorption.
- Saliva Production: Adequate saliva helps dissolve the substance, but excessive saliva might wash it away before complete absorption.
The sublingual method leverages the unique properties of the mucous membranes under the tongue to provide a fast, efficient, and convenient route for drug delivery. This method's efficiency and speed make it particularly suitable for substances like CBD oil, where rapid onset of action and high CBD Oil bioavailability are ideal.
3 Key Benefits of Taking CBD Oil Under the Tongue
Are you thinking of getting started with CBD oil? Here are the main Sublingual CBD Benefits of taking CBD oil under the tongue.
1. Increased Bioavailability
Bioavailability is the proportion of a substance that enters the bloodstream when introduced into the body and is therefore available to have an active effect. It is a critical concept in pharmacology and nutrition, as it determines the effectiveness of a substance. Key aspects of bioavailability includes:
- Absorption: The process by which a substance enters the bloodstream. The route of administration (oral, intravenous, sublingual etc.) significantly affects absorption rates.
- First-Pass Metabolism: The metabolism of a substance in the liver after it is absorbed from the gastrointestinal tract, which can reduce the amount of active substance that enters systemic circulation.
- Distribution: Once absorbed, the substance is distributed throughout the body to reach the target tissues.
- Elimination: The process of removing the substance from the body, primarily through the kidneys (urine) or liver (bile).
For CBD oil, bioavailability varies with the method of administration:
- Sublingual: Higher bioavailability (13-35%) as CBD is absorbed directly into the bloodstream through the mucous membranes.
- Oral Ingestion: Lower bioavailability (4-20%) due to the digestive process and first-pass metabolism in the liver.
- Inhalation: High bioavailability (up to 56%) as CBD enters the bloodstream quickly through the lungs.
- Topical Application: Bioavailability is generally low as CBD is absorbed through the skin and acts on localised areas rather than entering the systemic circulation.
The sublingual application of CBD oil effectiveness is measured by its quick absorption, higher bioavailability, ease of use, and consistent dosing. This method ensures that a greater proportion of CBD reaches the bloodstream directly, providing efficient and effective symptom relief.
2. Faster Onset of Effects
With sublingual administration, the effects of CBD are typically felt within 15 to 30 minutes. This relatively quick onset is due to the direct absorption of CBD into the bloodstream through the mucous membranes under the tongue, bypassing the digestive system and liver.
Here’s a comparison of the onset of effects between sublingual CBD oil and other common methods:
Sublingual CBD Oil
- Onset: Typically within 15 to 30 minutes.
- Reason: CBD is absorbed directly into the bloodstream through the thin mucous membranes under the tongue, allowing for rapid entry into circulation and quick onset of effects.
Oral Ingestion
- Onset: Can take 1 to 2 hours.
- Reason: CBD must pass through the digestive tract and liver, where it undergoes first-pass metabolism. This process delays the onset of effects compared to sublingual administration.
Inhalation
- Onset: Almost immediate, within minutes.
- Reason: CBD enters the bloodstream directly through the lungs, bypassing digestion and first-pass metabolism. This results in a very rapid onset of effects.
Topical Application
- Onset: Can vary widely – typically slower.
- Reason: CBD is absorbed through the skin and acts locally on the area of application. It may take longer for effects to be noticeable compared to methods that involve systemic absorption.
3. Ease of Use
Taking CBD oil safely involves a straightforward process with a few simple steps:
- Prepare the Dropper: Shake the CBD oil bottle well to ensure the oil is evenly mixed. Remove the cap and squeeze the bulb of the dropper to draw up the desired amount of CBD oil.
- Place Oil Under the Tongue: Tilt your head back slightly and use the dropper to place the desired amount of CBD oil under your tongue. It’s recommended to start with a low dose and increase gradually as needed.
- Hold for 60-90 Seconds: Let the CBD oil sit under your tongue without swallowing immediately. This allows for absorption through the mucous membranes.
- Swallow: After holding the oil under your tongue for 60-90 seconds, swallow any remaining oil. The absorbed CBD will continue to take effect as it enters your bloodstream.
- Rinse the Dropper: After using the dropper, rinse it with water to clean it. Store the CBD oil bottle in a cool, dry place away from direct sunlight.
Potential CBD Oil Side Effects and Safety Considerations
Common CBD Oil side effects of sublingual CBD oil include dry mouth, which occurs due to reduced saliva production. Gastrointestinal issues, such as diarrhoea or changes in appetite can also occur in some individuals. Some users may experience dizziness or lightheadedness, especially at higher doses.
While generally well-tolerated, it's important to start with a low dose and gradually increase it. You should also speak with your doctor before taking CBD to avoid any potential side effects and interactions with other medications.
