Fortunately, this guide will deliver comprehensive (yet easy-to-understand) information that covers everything about CBD oil and additional pro-shopping tips. We also include in it some of our best CBD oil brands that our customers love and patronise, provided with unbiased reviews and detailed product descriptions for you to consider in making the right decision.

A potentially beneficial yet non-intoxicating compound in cannabis, also known as cannabidiol (CBD), has gained a lot of attention— revolutionising the new and improved cannabis industry in the best way possible. Lucky for it, more scientific studies and anecdotal evidence have constantly supported the purported benefit of CBD in supplementing many different symptoms that can contribute to the development of specific health conditions, including pain, acne, anxiety, epilepsy, insomnia, and other serious health problems scientists are still yet to reveal.

For a quick refresher, CBD is a naturally occurring cannabinoid that can be extracted from different cannabis strains, including marijuana and hemp- although commercially used CBD products are mostly derived from the latter, which contains very little amount of THC or no THC at all. Tetrahydrocannabinol, commonly known as THC, is another prevalent cannabinoid responsible for producing the euphoric effects that are more likely associated with the use and consumption of marijuana. Not to be confused with the two cannabinoids because CBD and THC greatly differ when it comes to their characteristics and putative effects on the human mind and body.

Contrary to the most common misconceptions surrounding the two cannabinoid cousins, CBD does not contain any intoxicating properties, so there is no chance of causing a person to get “high” when it is consumed, unlike what usually occurs with THC.

A flurry of excitement celebrating the therapeutic potential of CBD minus the controversial intoxication has brought with it a whirlwind of CBD craze in the market. The last time we checked, CBD is now being extracted and formulated into a wide variety of forms, including oils, tinctures, capsules, and even cringe-worthy ones like passion pens and suppositories. With that being said, CBD has truly taken over the industry with one more mission: to fulfil our different needs and lifestyles.

While there are countless CBD products that exist nowadays, the most popular way to consume CBD is in its oil form. This increasing popularity has catalysed a number of producers specialising in CBD oil, with more and more dispensaries emerging every year.

What is CBD oil?

CBD oil is a blend of CBD extracts that sometimes contains other cannabinoids (including small traces of THC) and essential compounds like terpenes and flavonoids. Backed by scientific evidence, CBD oil is touted to supplement a lot of different health conditions by targeting symptoms of anxiety, chronic pain, acne, some types of seizures, and the long list goes on. There are several ways to harvest CBD oil from hemp and formulate it into a finished CBD oil product, but the most common process is performed by diluting CBD extracts in certain carrier oils such as olive, MCT, or coconut oil through a specialised form of equipment. CBD oil can be ingested orally, while topical solutions can be applied directly onto the skin.

CBD Oils vs Tinctures

As you search the web for CBD oil, you will likely come across another commonly-used term, “CBD tincture”. Many people use “CBD oil” and “CBD tincture” exchangeably- in beliefs that they are the same, but they don’t. You may not notice at first since they often appear in almost the same packages. Still, there are some notable distinctions between the two products. These involve important factors, such as:

  • Base Ingredient: Carrier oils are mixed with CBD extracts to formulate CBD oil, while alcohol is the base ingredient used in creating CBD tinctures. In essence, CBD oil is oil-based, while CBD tincture is alcohol-based.
  • Consumption Method: CBD oil can be taken orally by swallowing through the mouth or applied topically (depending on the carrier oil used). CBD tincture, on the other hand, is taken sublingually by holding a few drops under the tongue for a few seconds before completely swallowing. This method is done for quick absorption through the sublingual glands located underneath the tongue. Both products, however, can be consumed indirectly by adding them to the mix of food and drink recipes.

CBD oil and CBD tincture can be equally effective. However, when it comes to deciding which one is best for you, it will be very useful to consider your individual tastes and preferences.

Different Types of CBD Oil

CBD oil can be distinguished into three different types, namely CBD isolate, full-spectrum, and broad-spectrum. The table below demystifies the differences and potential advantages of each type over the rest.





  • Pure CBD extracts only
  • Well-refined
  • Suitable for first-time CBD users
  • Has no earthy aftertaste or odour


  • CBD extracts, other cannabinoids (including <0.2% THC), and the rest of all the chemical entities in hemp (such as terpenes, flavonoids, polyunsaturated fatty acids, and essential oils)
  • Has more potent effects due to a combination of all cannabinoids and additional compounds working synergistically to promote an “entourage effect
  • Has a very low amount of THC, not strong enough to produce a “high”


  • CBD extracts, other cannabinoids (except THC), and all the essential compounds in hemp
  • Provides an entourage effect without any involvement of THC 


The legal system is probably the biggest hurdle when it comes to buying CBD products. Fortunately, the stump for legalising all forms of hemp-derived products as well as scientific studies supporting CBD’s potential therapeutic value has gradually loosened some restrictions in many particular states worldwide. CBD products may not be legally available in all countries at the moment, but these are considered legal in almost every European country (including the United Kingdom) as long as the THC content in full-spectrum CBD products does not exceed the suggested amount of 0.2%.

In fact, the European Commission has now accepted that the extracts obtained from hemp can be considered for assessment as “novel food” rather than intoxicating narcotic drugs. In accordance with this, the European Food Safety Authority (EFSA) has recently implemented standard guidance on CBD-infused food products, stating any food products containing hemp-derived CBD (with or without <0.2% THC) must be approved as a novel food by the national food authority.

What to Look for When Buying CBD Oil

Despite the implementation of legal standards across the European CBD market, the chances of running into CBD products with questionable quality are still high. With many consumers pretty confused about which brand to choose from the many that exist, the surge in popularity can make it even harder to find the best CBD oils. Allow us to cut to the chase and make it all easier for you to get the access you need towards the right CBD oil that matches your style. The simplest way to avoid the risks of purchasing low-quality products by mistake is to make sure you pay attention to the following:


Look for manufacturing companies that comply with all the state laws we’ve mentioned above. High-quality and high-potent CBD oils must be derived only from hemp, and may contain THC levels of no more than 0.2%. A Certificate of Analysis (COA) is usually attached to the CBD product, encompassing all the information on its standard quality, including all the ingredients in the product, third-party lab results, as well as the place in which hemp is grown. Make sure the product comes from a safe agricultural environment that provides 100% vegan-friendly, toxin-free, and non-GMO CBD products.


CBD oil may vary in strengths or potencies from low to high, represented in percentage. It usually comes with a dropper to help you measure the amount of CBD oil you need to take. You may locate the suggested dosage from the packaging that specifies how much CBD is in a single drop. From there, you can easily figure out the number of drops you need to take in order to obtain your desired amount of CBD.

However, in some cases, the label indicates the total amount of CBD in the entire bottle instead of the specific amount that will be present in a single drop. Use the following standard formula in finding your ideal CBD dosage.

Since there are 1000 milligrams (mg) in a gram (g), divide the mg by g and then multiply the answer by 100 to get the percentage rate of CBD in each drop.

The table below shows some common potencies (in both mg) and their equivalent percentage:

CBD (mg)

Potency (%)

50 mg


100 mg


150 mg 


200 mg


300 mg 


500 mg


1000 mg



Let’s say, for instance, a 10-ml bottle of CBD oil contains 1000 mg of CBD in a total of 200 drops. Then each drop will likely contain 5 mg of CBD. So, in order to consume at least 50 mg, which is 5% of the CBD oil, you should take ten drops throughout the day.


When comparing the price of different CBD oil brands, you essentially want to ensure that you are paying for each milligram of CBD- and not the entire amount of liquid inside the bottle. When looking for CBD oil, always get the price per milligram of CBD. Here is how the formula works when getting the value equation of a CBD oil. In the table, we try to compare two CBD oil brands with different contents and prices.




Divided by CBD (mg)

Equivalent Price Per mg of CBD


10 ml CBD oil with 1000 mg of CBD 


1000 mg



10 ml CBD oil with 400 mg of CBD


400 mg



At first glance, CBD Oil A may look more expensive to buy when compared to CBD Oil B. However,  as CBD Oil A’s potency is much higher, you are more likely to get what you pay for, and you can even use fewer drops of CBD oil for the same potential effect. Even if CBD Oil B appears to be cheaper, you are actually paying double the price of CBD for the same quantity. With much lower milligrams, you will need to use more drops of CBD oil and might as well purchase another one when it is all consumed.

Does CBD oil work?

Many preliminary studies and anecdotal evidence attest to CBD oil’s holistic potential to supplement symptoms of many health conditions, including chronic pain, anxiety, acne and insomnia. While research is still ongoing, it is imperative to note that not everyone responds to CBD in the same way. Some factors, including lifestyle, age, and body mass index (BMI), can all influence the way your system reacts to CBD.

What is the standard dosage for CBD oil?

There is no standard dosage when it comes to CBD consumption. Everyone is encouraged to start with the lowest dose (usually 20 – 40 mg) and then increase gradually if needed. Other factors to consider when finding the right CBD dosage include age, weight, metabolism, health conditions (if there is any), and intended use.

Is it safe to use CBD oil every day?

CBD is non-intoxicating and therefore does not produce any euphoric effects. There are no reported overdosing cases on CBD, even in high concentrations, because it is a lipophilic (or fat-soluble) substance. Not only can you use CBD oil every day, but for the best possible results in most cases, you really need to take it on a regular basis.

Will CBD oil show up on a drug test?

CBD isolates and broad-spectrums won’t likely fail a drug test because they do not contain any trace amounts of THC. Full-spectrum CBD products (especially with illegally large amounts of THC) may, however, show up on a roadside drug test after taking the product.

How does CBD oil work inside the body?

Many studies have shown that CBD oil might assist in supplementing various health concerns by possibly interacting with the cannabinoid receptors distributed throughout the body via a specialised nerve-signalling system known as the endocannabinoid system (ECS).
