Do you find that most CBD oils aren’t strong enough to give you the desired effects? Chances are you need a more potent tincture.

Unfortunately, it’s not always easy to find high-strength CBD oil, especially if you want it to be affordable and of high quality.

That’s why we compared over 60 CBD products based on their strength, third-party lab test results, hemp quality, formula, price, and other criteria.

Here’s a review of the 11 strongest CBD oils, capsules, topicals, and other CBD products from reputable brands.

CBD Terminology

  • Terpenes: aromatic plant compounds with a wide variety of beneficial properties (1).
  • Minor cannabinoids: CBN, CBG, and other beneficial cannabinoids found in smaller amounts than CBD. For hemp, THC can also count as a minor cannabinoid.
  • Hemp: non-intoxicating cannabis variety with high CBD and low THC levels (less than 0.3%).
  • Full-spectrum: whole-plant hemp extract containing multiple cannabinoids, terpenes, and flavonoids. This form of CBD is about 4 times more potent than pure CBD (2).
  • Broad-spectrum: whole-plant hemp extract similar to full-spectrum CBD, but with THC removed (may contain trace amounts).
  • CBD isolate: pure CBD with all other hemp compounds removed.

Strong CBD Oil Buying Guide

Interested in buying strong CBD oil products but not sure where to start? We’ve put together this guide to answer the most common questions.

How Does CBD Strength Work?

CBD strength, also known as potency, refers to the concentration of CBD in a product. It’s usually expressed in milligrams (mg) of CBD per milligram (ml) of oil.

For example, a tincture with 1000 mg of CBD in a 30 ml bottle has a potency of 1000/30 = 33.33 mg/ml. If you take the same 30 ml bottle but with 2000 mg of CBD, it would have double the potency: 2000/30 = 66.67 mg/ml. 

The second option is much stronger, which also means you’d only need to take half the amount to achieve the same dose.

You can apply this principle to other CBD products. For example, strength for capsules is simply the amount of CBD per capsule. 

Understanding CBD potency is important because it can mean the difference between relief and not noticing any effects at all.

What Counts As a High CBD Strength?

Generally speaking, CBD oil concentrations of 40+ mg per ml (or per capsule/gummy) are considered high. Some CBD oil or CBD concentrate products can provide as much as 200–300 mg of CBD per ml. 

Why Do People Use Strong CBD Oil Products?

The average CBD user takes 20–50 mg doses of CBD 1-2 times a day. However, this amount may not be enough for everyone.

Whether it’s because you’re suffering from severe symptoms, have a high tolerance to cannabinoids, or simply have a less responsive endocannabinoid system, some people need to take higher doses of CBD to find relief. 

In that case, your best bet is to choose a strong CBD product. Another advantage of using high-potency CBD oil is that you need to take less to feel an effect.

Having said that, your chosen method of administering CBD will also influence its effectiveness.

How You Take CBD Matters

Most people use CBD in the form of oil, but there are many other product options, including capsules, gummies, vape e-liquids, and topicals. Each is absorbed by the body in a different way, which influences the effectiveness.

CBD is best absorbed through the sublingual (under-the-tongue) and inhalation (vaping/smoking) methods.

On the other hand, oral products such as capsules,  gummies, and other edibles have notoriously low bioavailability, meaning only a small portion of what you ingest reaches the blood and has an effect (3). 

That’s because much of the CBD gets lost in the digestive tract and liver before it can be absorbed.

The Type Of CBD Extract Matters

There’s one other key factor that affects the effectiveness of CBD oil — the type of CBD. CBD extracts come in three main forms: isolate, full-spectrum, and broad-spectrum CBD.

CBD isolate is pure CBD with all other hemp compounds removed.

Full-spectrum CBD is a whole-plant extract containing all of the cannabinoids, terpenes, flavonoids, and other natural compounds found in hemp. 

All these compounds work together in synergy, making full-spectrum CBD products more effective than those made with pure CBD. Researchers gave this phenomenon the name “entourage effect” (1).

Broad-spectrum CBD is similar to full-spectrum but undergoes an additional step to remove THC (although some small traces might remain).

To illustrate what this means for potency, let’s compare two CBD oils with the same strength of 50 mg/ml. One of these oils contains CBD isolate, while the other is made with full-spectrum CBD. 

The full-spectrum version will have stronger effects because it contains additional compounds that not only synergize with CBD but also have benefits of their own. 

That’s why it’s important to not only look for a strong product but also consider how you’re using it and which type of CBD extract it contains.

How to Find the Right CBD Dose

If you’re looking for strong CBD oil, chances are you didn’t find relief from a regular-strength product.

Unfortunately, there isn’t a CBD dosage that will work for everyone. Too many factors play a role, such as how much you weigh, your genetics, and the type of product you’re taking.

The best way to find how much CBD you need to take is to start with a small amount (or whichever amount you used before) and wait two hours to see how you feel (4). If you don’t notice any effects, gradually increase the dosage over time until you start to notice a difference.

How to Choose High-Potency CBD Oil

There are some key factors to keep in mind if you want to find an effective, affordable, strong CBD oil product:

  • Third-party testing: Done by an independent lab, third-party tests verify the potency and purity of CBD products. Reputable CBD brands pay for testing to reassure customers that they’re getting exactly what they paid for.
  • Type of CBD: Full-spectrum CBD produces the greatest effects. However, some people may need to choose THC-free options (broad-spectrum or isolate CBD).
  • Product potency: Potency is the amount of CBD you’re getting per dose. Everyone’s CBD dosage is different, so you’ll need to experiment to find your dose and use a product with the appropriate potency. The strongest CBD oils typically contain over 150 mg per ml.
  • Hemp source: CBD is extracted from hemp, so plant quality matters. We choose brands that use organic hemp and are transparent about their hemp source and growing process. 
  • Company reputation: Reputable CBD brands have hundreds of positive customer reviews and are transparent about their business.
  • Price: We look for affordable but quality CBD products to help you save money. We also consider shipping costs.
