What is CBD Oil?

CBD Oil is a natural dietary supplement made by using compounds extracted from the cannabis plant. CBD (cannabidiol) is one of over a hundred cannabinoids naturally found in cannabis and has become one of the most researched plant-based active ingredients in recent years.

The popularity of CBD Oil is due to its broad therapeutic range, meaning it may offer solutions for many health issues, while also having an excellent safety profile.

CBD Oil essentially consists of two main components:

• Extract that contains a concentrated amount of CBD, and depending on the product type, other natural cannabinoids, terpenes, and plant compounds as well.
• Carrier oil that aids in dosing and absorption of CBD. The most common carrier oils used for this purpose are MCT oil or hemp seed oil.

It is important to know that the name “CBD oil” does not refer to a single, uniform product. Two preparations with the same CBD content can differ considerably in their composition, quality, and properties depending on the plant variety used, the other natural plant ingredients they contain, the technology used in their production, and the quality control processes they have undergone.

How is CBD Oil Made?

Producing CBD Oil is a lengthy process that begins with cultivating cannabis.

Cannabinoids and other valuable plant compounds are extracted from the harvested plants using modern extraction methods. The extract is then purified, standardized, and mixed with carrier oil to ensure that every drop contains the exact same amount of CBD.

During the production of CANNADOL^TM CBD oils, we take care to preserve as many valuable compounds found in the plant as possible by using a chemical-free CO2 extraction method that operates at low temperature and pressure. This guarantees our oils have an outstanding and broad active ingredient profile.

Why Aren’t All CBD Oils the Same?

This is one of the most important questions many customers only ask after purchasing a product.

CBD oils can differ, for example:

• whether made with full-spectrum, broad-spectrum, or isolate CBD,
• the quantity of natural cannabinoids,
• the terpene profile (terpenes are aromatic essential oils that have significant therapeutic effects on their own),
• the type of carrier oil,
• the strictness of laboratory testing,
• and the manufacturing technology.

Therefore, the CBD amount on the label alone doesn’t tell you everything about a product’s quality. To make informed choices, it’s best to consider the full composition, lab test results, and manufacturer transparency.

Full-Spectrum, Broad-Spectrum, or CBD Isolate? Which is the Better Choice?

Many think all CBD oils are the same and that the only important factor is the CBD amount on the label. The reality, however, is much more complex.

CBD oils can be categorized into three main types:

• full-spectrum (Full Spectrum)
• broad-spectrum (Broad Spectrum)
• CBD isolate (CBD Isolate)

The key difference between them isn’t the CBD amount but rather the other natural plant compounds they contain alongside the CBD.

The cannabis plant is not made up of CBD alone. It contains hundreds of natural components including cannabinoids, terpenes, and flavonoids. These compounds work not in isolation but interact with each other. Research suggests this synergy—often called the entourage or accompanying effect—helps full-spectrum CBD oils have different, often enhanced properties compared to broad-spectrum or isolate-based products.

Therefore, when choosing the right CBD oil, it’s not enough to compare the CBD content in milligrams alone. It’s equally important to consider how the raw extract has been processed and whether the final CBD Oil is full-spectrum, broad-spectrum, or made using isolate.

FULL-SPECTRUM CBD OIL

Full-spectrum CBD oil contains CBD along with several other naturally occurring cannabinoids, terpenes, and flavonoids. It also contains small amounts of THC, typically under 0.2%.

THC (tetrahydrocannabinol) is the most well-known cannabinoid in the cannabis plant. Unlike CBD, it has psychoactive effects, meaning in larger doses it can cause intoxication and altered perception. However, THC is also recognized for its medical potential: clinical research shows it may help relieve chronic pain, reduce chemotherapy-induced nausea and vomiting, stimulate appetite, and ease muscle spasms associated with some neurological conditions. These benefits have mainly been studied with standardized medicinal products or medical cannabis. Because full-spectrum CBD products contain only low levels of THC, their use is not associated with psychoactive effects.

In CANNADOL^TM full-spectrum CBD oils, alongside CBD you’ll find 8–9 additional natural cannabinoids that strengthen each other’s effects.

Benefits of Full-Spectrum

• wide therapeutic range
• stronger anti-inflammatory effects due to presence of THC
• enhanced antitumor effects

When It Might Be a Good Choice

Full-spectrum CBD Oil is typically chosen by those looking for a product closest to the natural composition of the cannabis plant. However, because it can contain small amounts of THC, it’s not ideal for everyone in every situation. For example, tested athletes, workers undergoing regular drug screenings, or those highly sensitive to THC may prefer the broad-spectrum option.

BROAD-SPECTRUM CBD OIL

Broad-spectrum CBD Oil also contains various natural cannabinoids and terpenes but has had the THC removed.

That means part of the valuable compounds remain, while the product is THC-free.

A true broad-spectrum CBD oil contains not only CBD but also several accompanying cannabinoids and natural terpenes, distinguishing it from simple CBD isolate products.

Advantages

• suitable for animals sensitive to THC
• can be used in large quantities
• often a good compromise between full-spectrum and isolate

When It Might Be a Good Choice

Broad-spectrum CBD Oil is especially suitable for those seeking a THC-free product but who don’t want to miss out on the benefits of the entourage effect.

CBD ISOLATE

CBD Isolate is a natural product available as a crystalline powder that contains only CBD. From the cannabis plant, not only CBD but all significant cannabinoids can be isolated.

The benefit of isolate is its versatility. However, it lacks the natural cannabinoids and terpenes found in full- and broad-spectrum extracts.

Thus, CBD isolate is not “better” or “worse” — it’s simply designed for different purposes. A major advantage is its easy use in customized products, personal oil blends, cosmetics, or foods.

Of course, CBD isolate can also be combined. For enhanced therapeutic effect, we have formulated a product that contains CBD and an equal ratio of CBG to strengthen the effects of CBD.

How Does CBD Work? – The Role of the Endocannabinoid System

To understand how CBD works, it’s useful to start by getting to know one of our body’s most important regulatory networks: the endocannabinoid system (ECS).

Although discovered only in the 1990s, it’s now known to be present throughout almost the entire body, involved in finely tuning the function of numerous organs—from the brain and nervous system to the immune system, digestive tract, and skin.

The primary role of the endocannabinoid system is to help maintain homeostasis, that is, the internal balance of the body. It constantly adapts to external and internal changes, helping the body operate optimally.

The Three Main Components of the Endocannabinoid System

The ECS is made up of three fundamental components.

1. Endocannabinoids

Endocannabinoids are signaling molecules that are produced by the body itself when needed.

The two best-known:

• Anandamide (AEA) – often called the “bliss molecule.”
• 2-arachidonoylglycerol (2-AG) – one of the most important natural endocannabinoids.

Their job is to relay messages between cells and support various regulatory processes in the body.

2. Receptors

Endocannabinoids exert their effects by binding to receptors.

The most notable are:

CB1 Receptor

Primarily found

• in the brain,
• the spinal cord,
• and the central nervous system in large amounts.

CB2 Receptor

Mainly found

• in immune system cells,
• the spleen,
• and peripheral tissues.

While these receptors are not exclusively found in these areas, their differing distribution shows how involved the endocannabinoid system is throughout the entire body.

3. Enzymes

After endocannabinoids have served their purpose, special enzymes break them down.

The two best-known are:

• FAAH, mainly responsible for breaking down anandamide.
• MAGL, primarily responsible for breaking down 2-AG.

Thanks to this, endocannabinoids only act as long as they are truly needed.

How Does CBD Affect the Endocannabinoid System?

It was once thought that CBD binds to CB1 and CB2 receptors just like THC.

We now know this is not the case.

CBD binds very weakly to these receptors, so its mechanisms of action are much more complex.

Research indicates CBD can influence the endocannabinoid system in several ways:

- It may contribute to maintaining anandamide levels

- CBD can inhibit the FAAH enzyme, which breaks down anandamide. As a result, anandamide may remain longer in the body and extend its natural regulatory role.

It May Affect CB1 Receptor Function

CBD doesn’t directly activate the CB1 receptor.

Instead, it may act as a negative allosteric modulator, subtly modifying the receptor’s function without directly turning it on.

This is one reason CBD can attenuate some of THC’s unwanted psychoactive effects.

It Interacts with Numerous Other Receptors

Recent research shows that CBD’s effects are not limited to the endocannabinoid system.

It has been linked, among others, to interactions with

• the 5-HT1A serotonin receptor,
• the TRPV1 receptor,
• the PPAR-γ receptor,
• the adenosine signaling system,

This complexity helps explain why CBD’s effects cannot be attributed to the activation of a single receptor.

Why Is This Important?

CBD doesn’t target just one organ or biological process.

Instead, it interacts with the body’s natural regulatory systems involved in coordinating numerous physiological processes. Based on current research, CBD’s mechanism of action is complex and remains the subject of intense scientific investigation.

Therefore, it’s not accurate to say that CBD “acts on one receptor” or “works by a single mechanism.” Current scientific understanding points to multiple interconnected processes being simultaneously influenced.

What Does This Mean in Practice?

While many details of CBD’s mechanisms have been uncovered, research continues. Current scientific findings increasingly reveal that CBD doesn’t influence a single target but can subtly modulate several interconnected regulatory systems. This explains why it is a focus of scientific research and studied across many physiological contexts.

What is CBD Oil Used For?

The popularity of CBD Oil has significantly increased worldwide in recent years. One reason is the growing number of scientific studies examining cannabidiol (CBD) in relation to various physiological processes.

However, it is important to distinguish between scientific research results and commercial CBD products.

Currently available CBD oils in the European Union are not classified as medicines, so no claims can be made that they treat, cure, or prevent diseases.

Nevertheless, researchers provide growing information about the biological processes CBD may be involved in, so scientific interest remains very intense.

In Which Areas is CBD Being Studied?

Based on scientific publications, CBD is being researched in the following areas among others:

Stress and Anxiety

CBD’s application in stress and anxiety is one of the most studied areas.

Clinical trials and meta-analyses suggest that CBD may contribute to reducing anxiety symptoms under certain conditions. However, studies vary in dosage, methods, and patient groups, so further well-designed clinical trials are needed.

Related knowledge base: CBD oil and anxiety.

Sleep

Sleep quality is also one of the most studied areas.

Research indicates that CBD does not have a direct sedative effect. However, some studies show that for certain people, especially when stress or anxiety underlies sleep problems, sleep quality may improve.

Related knowledge base: CBD oil for sleep.

Pain

CBD has been studied in numerous pain models.

Current scientific evidence suggests CBD may interact with biological systems involved in pain perception and regulation. However, clinical findings are not yet conclusive and further research is necessary.

Related knowledge base: CBD oil for pain.

Inflammation

Laboratory and animal studies indicate CBD may positively affect signaling pathways related to inflammatory processes. Clinical research on humans is still limited, so there isn’t yet enough evidence to support its use for treating inflammatory diseases.

Nervous System

CBD’s neuroprotective properties have been intensively researched for over 20 years.

Studies include effects on:

• protection of nerve cells,
• oxidative stress,
• neuroinflammation,
• and various neurological disorders.

Skin

The endocannabinoid system is also present in the skin, so CBD is examined in cosmetic research for, among other things:

• sebum production,
• skin balance,
• and the skin’s natural protective functions.

Sports and Recovery

In recent years, interest in CBD has increased among athletes.

Research primarily focuses on the potential role of CBD in:

• post-exercise recovery,
• post-exertion comfort,
• and support for sleep and stress.

Note for athletes: Since 2018, cannabidiol (CBD) is no longer on the World Anti-Doping Agency (WADA) list of banned substances, so its use is allowed in competitive sports. However, this applies only to pure CBD. THC and many other natural cannabinoids remain prohibited during competition, so athletes should choose laboratory-tested CBD products from reliable sources.

What Does Current Science Say?

Thousands of new scientific publications on CBD appear every year, and our knowledge is continuously expanding.

However, it is important to emphasize that not all research findings can be directly applied to commercial CBD oils. Many studies are conducted in laboratory settings, on animal models, or with 99% pure CBD isolate, so scientific results must be interpreted cautiously and do not constitute automatic proof for various CBD products.

* The stars do not indicate how “effective” CBD is, but rather the quantity and quality of current human clinical evidence available for the given area.

How to Dose CBD Oil?

Dosing CBD Oil is one of the most common questions among customers, but there’s no one-size-fits-all answer.

Optimal dosage can be influenced by many factors, including:

• the concentration of the chosen CBD oil,
• age,
• body weight,
• individual sensitivity,
• purpose of use,
• and how your body responds to CBD.

For this reason, the “start low and go slow” principle is generally recommended.

Why Isn’t the Same Dose Right for Everyone?

CBD doesn’t work like many traditional medicines, where a specific dose corresponds to a certain body weight or age.

The endocannabinoid system varies between individuals, so the same amount can lead to different experiences in different people.

Therefore, it’s not advisable to copy someone else’s dosage.

Gradual Increase is Key

If you’re new to CBD Oil, it’s best to start with a small amount and gradually increase the dose.

This way, you can observe how your body responds and find the amount that works best for you.

Concentration and Number of Drops Are Not the Same

This is one of the most common misunderstandings.

Many people think:

5 drops = the same amount of CBD from every oil.

This isn’t true.

The same number of drops from CBD oils of different concentrations may contain different amounts of CBD.

When planning your dosage, pay attention not only to the number of drops but also to the amount of CBD per drop.

When Should You Take CBD Oil?

There’s no ideal time of day that suits everyone.

Some people:

• take it in the morning,
• others in the evening,
• while many split the dose into two daily parts.

The right time is often found through individual experience. Regularity is more important than the exact time of day!

How to Use CBD Oil?

CBD Oil is generally taken by placing drops under the tongue.

It’s recommended to hold the drops under the tongue for 60–90 seconds before swallowing to promote absorption through the oral mucosa.

How Long Until You Feel the Effects of CBD?

There is no one-size-fits-all answer here either.

Several factors can influence absorption speed and the bioavailability of the ingredients in CBD Oil, including:

- method of application,

- characteristics of the endocannabinoid system,

- individual metabolism,

- and the composition of the CBD Oil.

That’s why different people may experience CBD’s benefits on different timelines.

What to Keep in Mind When Dosing?

- Start with small amounts!

- Make changes gradually!

- Give your body time to adjust!

- Don’t copy others’ dosages!

- Always check the amount of CBD per drop!

- If you take medicine regularly, are pregnant or breastfeeding, or have known health conditions, consult your doctor or pharmacist before using CBD!

Frequently Asked Questions About Dosing

Can you use too much CBD Oil?

Based on research, CBD generally has a good safety profile, but higher doses may increase the likelihood of side effects (such as drowsiness or gastrointestinal issues). This supports the recommendation to dose gradually.

Is it better to take it before or after meals?

Both methods are acceptable. Some studies suggest that taking CBD with fatty foods may increase bioavailability, though individual differences are significant.

Can I skip a day?

CBD doesn’t require as strict a dosing schedule as many medicines, but regular, consistent use supports effectiveness.

Which CBD Oil Should You Choose?

When choosing the right CBD Oil, it’s not enough to look only at which product has more milligrams of CBD. Equally important are the type, concentration, cannabinoid profile, presence or absence of THC, and whether you are a beginner or experienced CBD user.

There is no single CBD oil that’s ideal for everyone. A good choice always starts from your individual needs.

1. First, decide: Are you looking for full-spectrum or broad-spectrum CBD oil?

This is one of the key questions. If you’ve read the related section above, it should be easier for you to decide. 

2. What concentration of CBD oil should you choose?

If You Are Just Starting with CBD

Beginners generally find it more practical to choose concentrations that allow dosing in small increments.

This way, it’s easier to follow the “start low, gradually increase” approach and to find the daily amount that suits you. It also helps observe how CBD oil affects you personally. You’ll be better off buying a lower concentration, and thus lower-cost, product first to see, for example, if you’re sensitive to THC.

If You Already Know How Much CBD You Use

Higher-concentration CBD oils may be better if you already know exactly how many milligrams of CBD you want to take daily.

With these, you can achieve the same CBD amount with fewer drops. Although “stronger” CBD oils may seem more expensive when looking only at the price of a 30ml bottle, if you calculate the cost per drop of active ingredient, the more concentrated products often turn out to be more economical.

Therefore, always compare the amount of active ingredient per drop, not just the percentage concentration.

3. Don’t Look Only at the CBD Content!

Two oils containing the same amount of CBD may have very different compositions.

You should check:

• which other cannabinoids it contains;
• whether it also includes CBG, CBDA, or other natural cannabinoids;
• which terpenes are present;
• what carrier oil is used;
• if there is independent laboratory testing.

So, the amount of CBD is just one piece of information among many. The more diverse cannabinoids a product contains, the better its therapeutic potential.

4. Check the Lab Results

Reliable CBD products should have accessible independent laboratory tests verifying the cannabinoid profile.

Lab results can reveal, for example:

• if the product indeed contains the CBD amount claimed on the label,
• which other cannabinoids it contains,
• whether THC is detectable,
• and if the product meets its declared composition.

That’s why for CANNADOL^TM products, we strive to make all available lab tests easy to access.

Related knowledge base: Full-Spectrum or Broad-Spectrum CBD Oil

Still Unsure Which One to Choose?

That’s completely normal. Often the question is not which product is the “strongest” but which composition and concentration best fit your individual needs.

If you’re uncertain, start with these three questions:

1. Do you want full-spectrum or THC-free CBD oil?
2. Are you a beginner or an experienced CBD user?
3. How many milligrams of CBD does each drop contain in the product?

If you can answer these, it will be much easier to choose the right product.
