10 Strongest CBD Oils You Can Buy in 2022

Don’t mess around with feeble CBD oils — go big or go home.

Strong CBD oil, generally speaking, contains an equivalent potency of 60 mg per mL of oil (or more).

CBD oil is usually sold in 1 oz (30 mL) bottles with 1 mL droppers.

The total CBD content can range from 300 mg up to 6000 mg.

The strongest CBD oils use full-spectrum hemp extract and contain between 200 and 300 mg of CBD per mL of oil.

10 Strong CBD Oils For 2022

When you’re looking for any CBD oil, it’s important to keep an eye out for brands that always do third-party lab testing, grow their hemp in the U.S., and have less than 0.3% THC (tetrahydrocannabinol).

Strong CBD oils are more expensive, so make sure you’re buying something that’s actually worth the money.

1. Kiara Naturals 3000 mg Full-Spectrum CBD Oil (300 mg/mL)

Kiara Naturals is best known for their holistic CBD formulas — such as their Deep Sleep Tincture or Pain Tincture.

The company also makes some high-potency CBD oils — such as this 3000 mg bottle of full-spectrum European-sourced hemp extract.

What makes this product different is that it comes in a much smaller bottle (10 mL instead of 30 mL).

This means every drop of oil contains three times the dose of CBD than conventional 1 oz bottles. Every milliliter of oil contains 300 mg of full-spectrum CBD extract.

2. Nordic Oil 2000 mg Full-Spectrum CBD Oil (200 mg/mL)

€39.00 – €129.00
Nordic Oil

CBD Potency: 50 – 200 mg/mL
Cost per mg CBD: €0.06 – €0.08
Extract Type: Full-Spectrum
THC Content: <0.02%

The standard bottle size for CBD oils in the US is 30 mL — but only 10 mL in Europe. This means products that seem on par with American products are three times stronger than you may initially think.

Nordic Oil 3000 mg full-spectrum CBD oil comes in the standard European 10 mL bottle size. This makes the potency roughly 300 mg per mL or 10 mg per drop.

3. Neurogan 12,000 mg CBD Oil (200 mg/mL)

$29.95 – $269.95
Neurogan

Neurogan CBD Oil 30 – 60 mL

Total CBD: 500 – 12,000 mg
Potency: 8.33 – 200 mg/mL
Cost per mg: $0.02 – $0.05
Extract Type: Full-Spectrum & Broad-Spectrum

Neurogan has one of the highest CBD levels we’ve ever seen. It’s a larger bottle, with 60 mL instead of the usual 30, but the total CBD concentration inside is 12,000 mg. That’s hands down the highest total amount of CBD we’ve seen in any one bottle of CBD oil.

This oil works out to an incredible 200 mg per mL of oil (nearly 7 mg per drop)!

4. Hemp Bombs 5000 mg CBD Oil (165 mg/mL)

Potency: 10 – 166.6 mg/mL
Cost per mg CBD: $0.05 – $0.08
Extract Type: Isolate
THC Content: 0%

Hemp Bombs only makes CBD isolate oils, but they have an incredibly wide range of flavors and potencies to choose from.

These oils come in standard 30 mL bottles, containing up to 5000 mg each. This works out to a dose of around 166.6 mg/mL of oil.

5. Eir Health Full-Spectrum CBD Oil (100 mg/mL)

$28 – $148
EIR Health

Eir Health Full-Spectrum CBD Oil 30 mL (1 oz)

Potency: 10 – 100 mg/mL
Cost per mg CBD: $0.05 – $0.09
Extract Type: Full-Spectrum
THC Content: <0.3%

Eir Health‘s strongest oils contain 3000 mg of CBD and are available in both full-spectrum and CBD isolate options.

Because of the added benefits of full-spectrum hemp extract, we consider the 3000 mg full-spectrum option to be the strongest.

These products are also some of the least expensive oils exceeding 2500 mg on the market.

6. CBDistillery 5000 mg CBD Isolate Oil (165 mg/mL)

$29.00 – $220.00
CBDistillery

CBDistillery CBD Isolate Tinctures 30 mL

4.17 / 5

7. Royal CBD 2500 mg Full-Spectrum CBD Oil (85 mg/mL)

Royal CBD Oil (2500 mg)
$49 – $229
Royal CBD

Royal CBD Oil 30 mL

5 / 5

Total CBD: 500 – 2500 mg
Potency: 16.6 – 83.3 mg/mL
Cost per mg CBD: $0.12 – $0.18
Extract Type: Full-spectrum
THC Content: <0.3%

Royal CBD has a 2500 mg full-spectrum CBD oil — which makes it one of the strongest full-spectrum oils on the market.

Full-spectrum products are generally not as high-potency as CBD isolate. The extra cannabinoids and phytochemicals compete for space in the oil solution.

While the total CBD levels are lower with full-spectrum products, they tend to have a much stronger effect overall due to the synergistic effects of the other cannabinoids and terpenes alongside CBD (AKA the entourage effect).

This is why we’ve placed this high-potency full-spectrum CBD oil at the top of our list.

8. Medterra 2000 mg Broad-Spectrum CBD Oil (65 mg/mL)

Cost per mg CBD: $0.05 – $0.06

Medterra is one of the largest CBD companies in the world, so it’s no surprise the company carries some of the strongest oils on the market.

Their strongest CBD oil contains 2000 mg of broad-spectrum CBD oil per 30 mL bottle.

This works out to around 65 mg of CBD per mL of oil — all 100% THC-free.

This oil contains 6000 mg of CBD per bottle in a 100 mL bottle.

10. Five CBD Full-Spectrum CBD + THC Oil (200 mg/mL)

Five CBD oil is made from a high-potency hemp extract with CBD, as well as THC and about a dozen other cannabinoids. The strongest option contains 6000 mg of CBD per 60 mL bottle, with around 115 mg of THC.

This oil works out to around 100 mg of CBD and 2 mg of THC per ml of oil.

How To Tell The Strength Of CBD Oil

Because each CBD manufacturer uses different sizes of bottles, different serving sizes, and varying potencies, it can be difficult to tell whether the CBD you’re purchasing is actually highly potent.

In order to figure out how strong your CBD oil is, you have to do one simple calculation:

Divide by the total CBD content by the volume of the oil (in mL).

For example, if you have a 2000 mg CBD oil, and a 30 mL bottle, you would divide 2000 by 30 to get~67 mg/mL.

CBD Strength Depending On Bottle Size & Total CBD Content

Total CBD 10 mL Bottle 30 mL Bottle (1 oz) 60 mL Bottle (~2 oz)
100 mg 10 mg/mL 3 mg/mL 2 mg/mL
300 mg 30 mg/mL 10 mg/mL 5 mg/mL
500 mg 50 mg/mL 17 mg/mL 8 mg/mL
1000 mg 100 mg/mL 33 mg/mL 17 mg/mL
1500 mg 150 mg/mL 50 mg/mL 25 mg/mL
2000 mg 200 mg/mL 67 mg/mL 33 mg/mL
2500 mg 250 mg/mL 83 mg/mL 42 mg/mL
3000 mg 300 mg/mL 100 mg/mL 50 mg/mL
4000 mg X 133 mg/mL 67 mg/mL
5000 mg X 167 mg/mL 83 mg/mL
6000 mg X 200 mg/mL 100 mg/mL
7000 mg X 233 mg/mL 117 mg/mL
8000 mg X 267 mg/mL 133 mg/mL
9000 mg X 300 mg/mL 150 mg/mL
10000 mg X X 167 mg/mL
11000 mg X X 183 mg/mL
12000 mg X X 200 mg/mL

Why The Strength of Your CBD Oil Matters

The strength of your CBD is important for one very obvious reason — it impacts how much CBD is in your system. With any drug or substance, it’s important to know how much you’re taking and how often.

When you’re taking high-potency CBD, it can be difficult to get a specific mg dose each and every time. So, if you’re prescribed a specific dose by your doctor, it might be a good idea to stick with a lower-strength CBD.

This isn’t because the higher potency CBD oils are more wily, but rather because you’re squeezing more mg of CBD into each 1 mL dropper, so your measurements are bound to be less precise.

CBD strength is also important because you can track the effectiveness of your CBD regimen when you know how much you’re taking. If you switch between dosages without care, you’re likely to have an inconsistent regimen that could render it less effective over time.

The Benefits of Strong CBD Oil

There aren’t a lot of clinical studies pointing specifically to the merits of strong CBD oil for specific medical uses just yet. However, it is generally accepted that your dose of CBD oil is dependent on your weight and how strong of a dose you want.

The benefits of strong CBD oil are essentially the same as other benefits of CBD, but as you take stronger doses, you’ll likely experience stronger effects.

Keep in mind that your body expels a lot of the CBD you ingest during the digestion process. If you want to take a high mg dose, it might be a good idea to get a high potency CBD oil, so your body has more CBD to absorb into the bloodstream after digestion.

How To Make CBD Oil Stronger

You can get the most out of your CBD oil with a few easy steps that’ll make sure you’re giving your body every chance to absorb that compound into your bloodstream. Here are a few tips.

1. Hold The Oil Under Your Tongue Before You Swallow

There are large veins and thin tissue underneath your tongue, giving you an effective way to get substances into your bloodstream faster.

This is called sublingual administration, and it’s the best way to ingest CBD oil. Rather than allowing the CBD to begin digesting in your stomach right away, by placing it on your tongue, you’re giving the CBD an opportunity to enter the bloodstream before the metabolic process begins.

2. Leverage the Entourage Effect

The entourage effect refers to the concept that introducing several cannabinoids to your system at the same time will increase the effects of those cannabinoids, including CBD. You can achieve the entourage effect by purchasing full-spectrum CBD oil or by using THC in conjunction with your CBD products.

3. Try Liposomal CBD

Liposomal CBD is a relatively new type of CBD. Each CBD molecule is packaged in a liposome, which keeps the CBD molecule protected during the first pass metabolic process.

That means once you’ve finished digesting the CBD you took orally, there’s still CBD in your system ready to be absorbed by the bloodstream.

This is a way of increasing the bioavailability of CBD, and it can be super effective for high-strength CBD oils.

What Strength Of CBD Oil Should I Use?

Although there is no evidence that taking too much CBD is physically dangerous, it can lead to a mild euphoric feeling — as well as nausea or lightheadedness in some cases — that some users don’t want.

That’s why it’s important to determine the right dose of CBD for your body, depending on your weight and how strong you like your CBD.

Our dosage calculator makes it easy to determine which strength of CBD oil to buy for your purposes.
