How to take CBD oil correctly under the tongue

Although the method of taking CBD sublingually is very specific, it is also incredibly simple.

CBD oil must be placed under the tongue and held for at least 60 seconds without swallowing to give the molecules enough time to diffuse into the body through the epithelial cells.

It is important to note that the substance must be held under the tongue, as different areas of the mouth have different cell types and not all of them may be permeable enough for diffusion into the bloodstream.

This method remains the same whether one takes CBD oils or tinctures, or different dosages.

There is no correct dosage or the best time to do it, as it varies depending on the person and the condition being treated.

Furthermore, it is recommended not to take CBD during or immediately after a meal, as some of the oil may be absorbed by food particles and not by the bloodstream.

So, how often should CBD oil be taken under the tongue?

The frequency of Cannabidiol oil intake depends on the individual and is related to various factors, such as body weight and the severity of the disease.

Although it varies, most people take CBD oil sublingually once or twice a day, in the morning or a few hours before going to bed.

Consulting a qualified nutritionist can help you understand when it is best to take CBD oil, depending on the benefits you want to bring to your body.

But what makes sublingual intake so special compared to other methods?

3 benefits of taking CBD oil under the tongue (which make this method better than others)

1. Increased bioavailability

Since sublingual application bypasses the metabolic process of digestion, the possibility of ‘losing raw CBD’ is minimized.

The term bioavailability refers to the amount of a substance that can be utilized by the body, along with the degree and speed with which it reaches the systemic circulation.

As far as CBD products are concerned, the only method with higher bioavailability than sublingual is inhalation.

2. Faster effect

Similar to the higher bioavailability, bypassing the slow digestion process means that the effect of CBD tinctures taken sublingually can be felt much more quickly.

While it can take more than 30 minutes to benefit from oral CBD consumption, taking CBD oil sublingually can yield results within minutes.

3. Ease of use

As there is no need to prepare the product or inhale smoke (hashish or inflorescences) and vapour, the sublingual application is easier.

Just put a few drops under your tongue, do not swallow for about a minute, and let your body do the rest.

Is cbd oil under the tongue safe?

Is holding CBD oil under the tongue safe?

The answer is yes.

CBD oil is considered safe compared to most substances.

In other words, taking CBD oils sublingually does not increase the risk of CBD-related side effects compared to oral consumption.

Furthermore, CBD oil has no psychoactive effects and does not impart the so-called ‘high’ feeling, unless it contains THC. If you take a certified CBD oil product that does not contain THC, you will not experience the side effects commonly associated with THC, such as:

  • anxiety;
  • increased heart rate;
  • slowed reaction time;
  • memory loss.

On the other hand, CBD oil alone can help you relax, sleep more deeply and unwind.

Nevertheless, as a matter of ethics, possible side effects of the sublingual application of CBD oil should be considered. It must be said that these are mild and infrequent, but should be mentioned.

Here are the main ones:

  • slight numbness under the tongue
  • aversion to the consistency of CBD oil;
  • aversion to the taste of CBD tinctures.

How Long Does CBD Oil Under the Tongue Take to Kick In?

CBD enthusiasts often find themselves in the midst of a crucial question: How long does it take for CBD oil under the tongue to kick in? Understanding the nuances of this process involves delving into the various aspects of taking CBD sublingually and the intricacies of its absorption.

When it comes to taking CBD oil sublingually, also known as using the sublingual method, individuals typically place a few drops of CBD oil under their tongue, allowing it to be absorbed directly into the bloodstream through the mucous membranes. This method offers potential advantages in terms of quicker onset and increased bioavailability compared to other forms of consumption, such as taking CBD orally or using CBD capsules.

The efficiency of CBD sublingually absorption is influenced by factors like the type of carrier oil used in CBD products. MCT oil or coconut oil is often employed, facilitating the binding of CBD extract and ensuring a smoother absorption process. This sublingual administration capitalizes on the rich network of blood vessels under the tongue, expediting the journey of CBD into the bloodstream.

Scientific literature suggests that CBD sublingually administration may result in a faster onset of effects compared to oral consumption, especially when taken on an empty stomach. However, the actual time it takes for CBD oil under the tongue to kick in can vary among individuals based on factors such as metabolism, the amount of CBD taken, and individual health characteristics.

The sublingual use of CBD is generally considered a low-risk method, offering health benefits with as much CBD as possible being absorbed. Users may experience a slight burning sensation due to the natural ingredients in the oil, but this is typically temporary and well-tolerated.

For those seeking the therapeutic effects of CBD without the potential delays associated with the digestive system, CBD take sublingually offers a promising alternative. It is essential to note that while the sublingual method is generally safe, individual responses may vary, and it’s advisable to start with a few drops and adjust as needed based on personal experience.

In summary, the sublingual use of CBD, with its direct absorption under the tongue, holds the potential for a quicker onset of effects and increased bioavailability. As with any CBD product, it’s recommended to consult with a healthcare professional, especially for those with existing health conditions or concerns.

How Long Does Sublingual CBD Stay in Your System?

When considering the effects of sublingual CBD, one might naturally wonder, “How long does sublingual CBD stay in your system?” Unraveling this question involves exploring the dynamics of taking CBD oil sublingually and its impact on the body’s processes.

Taking CBD oil sublingually involves placing a few drops of CBD oil under your tongue, allowing for direct absorption into the bloodstream through the mucous membranes. This method is often favored for its potential to provide quicker onset and increased bioavailability compared to other forms of consumption, such as taking CBD orally or using CBD tinctures.

The duration of sublingual CBD in your system is influenced by various factors, including individual metabolism, the amount of CBD taken, and the specific CBD product used. While the effects may be felt relatively quickly, the actual presence of CBD in the body can vary.

In contrast to vaping CBD or using topical CBD products, which may have more localized effects, sublingual CBD interacts with the entire system due to its direct entry into the bloodstream. The active ingredient from the cannabis plant is efficiently absorbed under the tongue, providing a holistic impact.

It’s important to note that, compared to CBD taken orally, sublingual administration may result in less CBD being broken down by the digestive system. This can contribute to a prolonged presence of CBD in your system.

Scientific literature, including systematic reviews, has highlighted the potential benefits of sublingual CBD, emphasizing its efficiency as an active ingredient in providing therapeutic effects. The precise duration CBD stays in your system can vary among individuals, and factors like body weight, metabolism, and the specific product used play a role.
