Everything you need to know about the strongest CBD oil on the market, a few examples of the strongest CBD oil, and some tips to help you buy your first CBD oil and make the most of it.

The demand for CBD oil has skyrocketed over the last few years. More people are taking CBD for more severe ailments as studies keep streaming in, confirming some of the benefits CBD has been thought to have.

Initially, CBD was only present in low concentrations, which were suitable for minor discomfort and other mild problems. But as people try to see what else CBD can do, the need to find stronger CBD products has become inevitable.

CBD fans looking for the strongest CBD products can choose between CBD vapes and CBD oil. Because some people have reservations about vaping, CBD oil is the most common and usually comes in the highest CBD concentrations. It is perfect for anyone that wants to consume astronomical amounts of CBD in small quantities.

This guide is perfect if you're looking for the strongest CBD products. It covers everything you need to know about CBD oil strengths and how to pick the right one.

What is CBD?

Since it was discovered, the cannabis plant has attracted much attention from researchers and scientists because of its potential wellness benefits. During the research, many chemical compounds with active ingredients that interact with the body, known as cannabinoids, have been uncovered.

The first cannabinoid uncovered was delta 9 THC, best known for its uplifting benefits. CBD is another cannabinoid that has attracted even more attention because it doesn't have the same uplifting properties as Delta 9 but is thought to have the same therapeutic and wellness benefits.

Due to its unique non-uplifting properties, CBD has quickly risen to rival delta 9 THC in popularity as most people prefer it because it doesn’t change their state of mind.

Where Does CBD Come From?

CBD is a naturally occurring compound in the marijuana and the hemp plant but is more abundant in the latter.

The CBD used to make CBD products sold online and in brick-and-mortar stores is harvested and extracted from hemp plants recognized as legal by the 2018 Farm Bill. These hemp plants contain less than 0.3% THC. The low THC concentration makes them perfect for CBD fans that want the balancing benefits without the uplifting properties.

CBD is extracted from specific hemp plant strains with high CBD yield and low THC. These plants are legal, and the CBD extracted from them, and the subsequent products are federally legal.

How CBD Works

It’s a wonder how one compound can have so many benefits for the human body. The full details of the functioning of CBD in the body are still a well-kept secret, but science is gradually peeling back the layers.

Although we don’t know everything about how CBD works in the body, the basics are well understood, and we can create a clear and accurate picture of the details of how CBD works in the body.

CBD relies on a system present in the body called the endocannabinoid system or the ECS. The system is found in every mammal and maintains balance in various functions like memory, sleep, mood, and appetite, among many others.

The ECS comprises two types of receptors:

  • The CB1 receptors: These are present throughout the body. But have the largest concentration in the brain. They help coordinate movement, emotion, appetite, and memory, among other functions.
  • CB2 receptors: These are common in the immune system. They mainly control immune system responses.

When you take any CBD product, the CBD attaches to the CB2 receptors and very loosely to the CB1 receptors.

The CBD, through the ECS, stimulates the body to produce its own cannabinoids, known as endocannabinoids which help to restore balance and produce the different effects you feel when you take CBD.

Because CBD binds too loosely to the CB1 receptors able to produce positive effects on mood but cannot produce the uplifting effects of THC, which binds strongly to the same receptors.

What is CBD Oil?

The terms CBD and CBD oil are almost always used interchangeably. But they don’t refer to the same thing. CBD oil is one of the many products made using CBD extract. It contains CBD as the main component.

CBD oil may only contain two ingredients: CBD extract and carrier oil. But you're more likely to find CBD oils that contain more than two ingredients. CBD oils might include other ingredients like natural flavors, terpenes, and flavonoids.

The carrier oil used in your selected CBD oil might also vary depending on the brand. The most commonly used carrier oils are:

  • Hemp seed oil
  • MCT oil
  • Coconut oil
  • Avocado oil

Each carrier oil has benefits and adds a unique profile to CBD oil. You should carefully consider the carrier oil and ensure it matches the benefits and experiences you want from your CBD oil.

Benefits of CBD Oil

CBD oil is one of the easiest CBD products to get your hands on. They are readily available, and although they have been on the market the longest, they have remained unchanged. Still, they attract new and seasoned CBD fans because of their many benefits. Some of the reasons people prefer CBD oils over other CBD products include the following:


CBD oils are among the most diverse product in the market. CBD oils come in multiple configurations. They include flavored and unflavored options, CBD oils made from full-spectrum, broad-spectrum, or CBD isolate, and CBD oils containing other natural ingredients known for their wellness benefits, like tea tree oil, and mint, among others.

With CBD oil's diversity, you will easily find a product that perfectly meets your CBD intake needs.


CBD oils have among the highest CBD concentrations of all CBD products. While most CBD products don’t pass the 1000mg threshold, you can find CBD tinctures with up to 5000mg of CBD and more.

This makes them ideal for people with a high CBD intake or those taking CBD for its potential medicinal benefits and needing it to be in high concentrations.

With the high concentration of CBD oils, you can reach your daily CBD concentration intake while taking small amounts of CBD.

Easy to take

Being one of the premier CBD products and the most common, the method of administration for CBD is simple. The CBD oil bottle comes with a dropper that you use to transfer the CBD from the bottle to your mouth. The dropper is calibrated to deliver a specific number of drops to accurately measure servings.

Also, you can customize your CBD intake. Unlike CBD gummies or capsules that have pre-set servings, with CBD oil, you can measure the amount of CBD you want to take, allowing you to fully customize your intake to your needs.

Common Methods of Taking CBD Oil

Another reason CBD is so popular is that you can take it in several ways. For people that take CBD regularly, having multiple ways to enjoy your CBD adds adventure and helps you keep up with your routine without getting bored. Some of the common ways CBD fans use to take CBD oil include:


Oral administration is the most common method of taking CBD oil. It involves taking CBD oil drops and placing them on your tongue.

Although common, this method has the slowest onset of effects because the CBD must complete digestion before absorption. Also, some of the CBD is destroyed by stomach acid, so the bioavailability is low.

On the flip side, taking CBD oil orally has the longest-lasting effects. The CBD effects kick in gradually and last for several hours.

Because the effects kick in gradually, this method is preferred among those trying CBD oil for the first time and don’t want the sudden effects that kick in suddenly.


If you want a more effective method with faster and more intense effects when taking CBD oil, you should try taking it sublingually. When taking CBD oil sublingually, place the drops under the tongue (in the buccal cavity). Hold the CBD oil there for up to a minute and swallow what remains.

The area under the tongue has a thin layer of tissue with a rich supply of capillaries. It is perfect for the quick absorption of CBD into the bloodstream foregoing the digestive process.

This method of taking CBD is more effective, with a faster onset of effects. However, the effects kick in at once and don't last as long as when taking CBD orally. But because you swallow some of the unabsorbed CBD, you may experience prolonged results.

Mixing CBD oil with your food or drink

One of the downsides of taking CBD oil orally or sublingually is having to deal with the naturally bitter taste of CBD. Most people can’t stand it. So, the alternative is to mix your CBD oil in food or drink to mask the flavor and make it easier to take down.

Instead of placing the CBD oil drops in your mouth or under the tongue, you add them to your food or drink and take it as you normally would.

When doing this, ensure the food or drink is not too hot because the high temperature can denature the CBD and make it less effective. Only add CBD to cold drinks like smoothies and fresh juices if possible to protect its integrity.

What is CBD Oil Strength?

One of the very first things you should check, and you will notice when your CBD oil arrives, is the CBD strength. Most brands have the strength appearing conspicuously on the package because it is also a major selling point for CBD oils.

But what is CBD strength, and why does it matter?

CBD oil strength refers to the amount of CBD you're getting per milliliter of CBD, measured in mg/ml. If you purchase a 500ml bottle of CBD oil with 5000mg CBD oil strength, it means the strength of the CBD oil is just 10mg per ml of CBD oil you take.

It’s important to know how much CBD you’re getting per ml to know if you’re reaching your daily recommended amount. To determine the strength of your CBD oil, you should divide the milligrams indicated on the bottle by the milliliters it carries.

How Does Dosage Affect the Strength of CBD Oil?

You can increase the strength of your CBD oil and, consequently, the intensity of the effects you experience by taking more CBD oil. When you take more CBD oil, you increase the concentration of CBD and hence the CBD strength.

Lower CBD servings have lower strength. If you take a CBD oil with a CBD strength of 10mg per ml, and you take only one ml, you get 10mg. But if you take 2ml, you will get 20mg of CBD, producing more intense results.

What CBD Strength Do I Need?

CBD strength is more like CBD servings. There's no specific amount that works for everyone. So, you have to troubleshoot to work out your ideal strength. While at it, you should know several factors play a crucial role in determining your ideal CBD strength.

  • Height and weight – Taller and heavier individuals need more CBD to experience the effects. CBD passes through the bloodstream to reach the ECS. If you have a larger frame, you have more blood volume, which means the CBD will be diluted more. You can counter this effect by taking higher-strength CBD.
  • Age – Your metabolism is another factor to consider when taking CBD. It helps break down CBD; as we age, it becomes less effective, meaning CBD sticks in our systems longer. That means, as you grow older, you may need to take less CBD with less strength.
  • Experience with CBD – People who have been taking CBD for a while are likely to build tolerance and would need to take higher concentrations to continue feeling the effects. Starters, on the other hand, can get noticeable effects from taking a small amount of low-concentration CBD.

As mentioned earlier, the CBD oil market is one of the broadest there is, especially in terms of CBD strength.

Koi CBD is among the brands that have the strongest CBD oils in the market, which include the following:

1. Koi Complete Full-Spectrum CBD Oil Natural, 5000mg

Koi Complete Full Spectrum CBD Oil - Natural - 5000 mg

The Koi CBD full-spectrum CBD natural hemp 5000mg (166.7 mg per serving) is one of the strongest CBD oils on the market. Its minimal ingredient composition means a higher CBD concentration because there is reduced dilution.

3. Koi Naturals CBD Oil Tincture, 2000mg

Koi Naturals CBD Oil Tincture - 2000 mg

The Koi Naturals CBD oil tincture comes in various concentrations. The 2000mg is Koi’s third strongest and one of the strongest you will find on the market.

Things to Consider When Choosing the Strongest CBD Oil

CBD strength plays a critical role in your CBD experience. But it's not the only factor. Other factors will also determine the type of experience you get with CBD oil. Besides getting the strongest CBD oil, you must remember that the CBD market is not fully regulated. That means you could easily land on a substandard bottle of CBD if you don't do your research. To help you buy the best CBD oil, we have put together a list of factors you should consider that will improve your chances of getting the best and the strongest CBD oil.

Brand reputation

It's easy to jump on the first CBD oil brand you see with a high CBD concentration. But that would be a big mistake! Instead, you should know the best and most reputable CBD brands. The ones known for producing quality CBD oils and having rigorous quality assurance standards.

Usually, brands that have been around for a long time are the most reputable. Hemp brands only survive a long time if they deliver quality CBD products that keep buyers coming back.

Hemp source

Hemp products tread a very thin legal line. Although they are legal, there are conditions that must be met. Among them is ensuring you have the right hemp strains that produce less than 0.3% THC. This is where the origin of the hemp used to make the CBD oil comes into question.

US hemp farms are known to have rigorous standards and only grow the right strains of hemp. Most of these farms only use organic farming methods guaranteeing the safety and quality of their plants and the subsequent extract. This is crucial because the extract determines the quality of the final product.

Customer reviews

Another factor to consider when buying the strongest CBD oil is what other CBD consumers are saying about the CBD oil you want to buy and the brand. Going through customer reviews helps you create an expectation of the experiences the CBD oil you choose will deliver of the experiences of its previous consumers.

Most CBD brands have a customer review section that you can use to see what other CBD fans are saying. You can also use third-party review websites. These have verified consumer reviews. With the reviews, you have unbiased insight into the quality of CBD products the brand offers.

It’s not uncommon for even the best brands to have a few negative reviews. So don’t expect to find a brand with anything but positive reviews.

Third-party lab testing

The CBD market needs more regulations. Landing on a substandard CBD product, especially when buying CBD oil online, is easier than you think. To build customer confidence and trust, the best CBD brands work with independent, ISO-certified labs that test each batch of CBD oil before shipping them to customers and retailers.

The labs test for composition, purity, contaminants, and CBD concentration. The labs publish the results in a Certificate of Approval that is published on the brand's website.

While most CBD lovers use these tests as a standard of quality, there is more information you can get from the CoA, including confirmation of the CBD ingredients in the product versus those written on the package and confirming the CBD strength of the product.

The results should be accessible to all customers before purchasing the CBD oil. If you can find the CoA for your preferred CBD oil, that is a huge red flag.
