Do you find that most CBD oils aren’t strong enough to achieve desired effects? Chances are you need a high-potency tincture.

Unfortunately, it’s not always easy to find strong CBD oil, especially if you want it to be affordable and high-quality. To help you make an educated choice, I compared the potency, effects, hemp source, minor cannabinoid levels, price, and other criteria of over 60 CBD tinctures.

Here are my top picks for high-potency CBD oil.

6 Strongest CBD Oils

I divided my recommendations for the best high-potency CBD oils into six categories to help everyone find the best fit.

CBD Glossary

  • Hemp: cannabis variety with high CBD and low THC levels (no more than 0.3%).
  • Terpenes: aromatic plant compounds with various beneficial properties (1).
  • Minor cannabinoids: CBN, CBG, CBC, and other beneficial cannabinoids found in smaller amounts in hemp. They may work in synergy with CBD.
  • Full-spectrum: whole-plant hemp extract containing multiple cannabinoids, terpenes, and flavonoids. This form of CBD is about four 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 without any other hemp compounds.

My top pick for the strongest CBD oil goes to R&R. It’s one of the most potent CBD oils I’ve tried. Better yet, it’s certified organic by the USDA, boasts impressive minor cannabinoid levels (10-15%), and comes at a great price.

R&R is a top-tier CBD brand that’s affordable, certified by the US Hemp Authority, and boasts rich minor cannabinoid and terpene levels in its products.

My experience: I tested the 2500 mg fresh mint CBD oil for several weeks. It has a pleasant, mild mint taste and a dark color I expect from high-quality oils rich in minor cannabinoids and terpenes. I felt potent calm and relaxation within 20 minutes of using this tincture, with the effects lasting for several hours.

You can choose from classic, chocolate mint, and strawberry lemonade flavors.

Lazarus Naturals is an employee-owned brand that controls every step of the process, beginning with USDA-certified organic hemp grown in central Oregon.

My experience: This is probably my favorite CBD oil. I’ve bought and tested it more times than any other CBD tincture. I get reliable calming, relaxing, and often mood-enhancing effects that last for a good 4-6 hours.

If you’re looking for the strongest THC-free* CBD oil, I recommend cbdMD. Its broad-spectrum tinctures are some of the most potent on the market, with strengths as high as 250 mg per ml.

They come in natural (unflavored), berry, orange, and mint flavors and are fairly cheap. CbdMD’s products are sourced from organic hemp grown in Kentucky and Colorado.

Cons:

  • Levels of other minor cannabinoids are a bit low

Cannabigerol (CBG) is a popular cannabinoid, especially for daytime use. This full-spectrum tincture combines 2000 mg CBG with 4000 mg of CBD, giving it a high potency of 67 mg CBG per ml or 200 mg/ml of cannabinoids in total.

Wisconsin’s Batch CBD makes small batches of potent full-spectrum CBD products at affordable prices.

My experience: I tested half a dropper Batch’s Gold Reserve during the day. It had a pleasant lemon taste. I felt more relaxed and upbeat for the next several hours. I also tried taking a full dropper before bed and it helped me get deeper sleep.

Pros:

  • Comprehensive third-party and in-house testing
  • Rich in CBDa

Cons:

Raw CBD products contain high levels of cannabidiolic acid (CBDa), CBD’s parent molecule. Raw CBD oils are your best bet if you want to use CBD and hemp in the most natural, unprocessed form possible.

Endoca’s raw CBD oil is one of the strongest products on the market, with an incredibly high potency of 300 mg/ml. It contains about 15–20% CBDa and has only two natural ingredients: full-spectrum hemp extract and hemp seed oil.

Founded in 2010, Endoca is one of the world’s oldest and most respected CBD brands. Its products are sourced from organic Danish hemp grown in partnership with local farmers and tested both in-house and by a third-party lab.

Pros: 

  • Exceptionally low price
  • Comprehensive third-party testing

Cons:

  • Even stronger potencies would be good

CBD isolate is a pure form of CBD without any other hemp compounds. I’m a fan of Crescent Canna if you want to use pure CBD isolate oil.

Its max strength drops are the strongest CBD isolate oil I’ve ever tried, providing 300 mg CBD per ml. They come in peppermint and mandarine lime flavors.

My experience: Although it wasn’t as strong as the full-spectrum oils on this list, this was the strongest pure CBD tincture I’ve ever tested. I felt relaxing and calming effects that helped me fall asleep.

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. Taking the same 30 ml bottle with 2000 mg of CBD would double the potency: 2000/30 = 66.67 mg/ml. 

The second option is much stronger, meaning 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?

CBD oil concentrations of 50 mg/ml or more are considered high. But these days, many brands offer much stronger options, like 100 mg/ml and going as high as 200-300 mg.

Why Do People Use Strong CBD Oils?

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

Whether it’s because you’re suffering from severe symptoms like chronic pain, have a less responsive endocannabinoid system, or some other reason, some people need to take higher doses of CBD to find relief. 

In that case, your best bet is to choose a strong CBD CBD oil. Another advantage of high-potency CBD oil is that you need to take fewer drops to feel the effect.

Factors That Influence the Effects of CBD

Although potency is the biggest factor determining how strongly CBD affects you, the type of CBD and how you take it are also important.

How You Take CBD Matters

Most people use CBD as oil, but there are many other product options, including capsules, gummies, vape e-liquids, and topicals. The body absorbs each 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

One other key factor influences the effectiveness of CBD oil — the type of CBD. CBD extracts come in three main forms: isolate, full-spectrum, and broad-spectrum CBD.

  1. CBD isolate is pure CBD with all other hemp compounds removed.
  2. Full-spectrum CBD is a whole-plant extract containing all 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 with pure CBD. Researchers gave this phenomenon the name “entourage effect” (1).
  3. 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 synergize with CBD and 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.

Choosing the Right 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. There are many individual factors to consider, like how much you weigh, your genetics, and the type of product you’re taking.

The best way to find the ideal CBD dose you need is to start with a small amount (or whatever dose you use before) and gradually increase it over time (4). Do this until you find the dosage that gives the desired effects.

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 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 get 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. I 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: I look for affordable but quality CBD products to help you save money. I also consider shipping costs.
