If CBD isn’t having the desired effect, you might want to try something stronger. Not all extra-strength CBD gummies passed our vetting, but these get the green light.

High potency cannabidiol (CBD) might be a good fit if you’re not experiencing noticeable effects at lower doses.

For this article, we’ve focused on extra-strength gummies that contain up to 100 milligrams (mg). The three products included in this article are the strongest CBD gummies that pass our vetting and testing.

Note that what feels strong to you might not affect someone else in the same way. It’s always best to start increasing your dose little by little before jumping to maximum strength.

The type of CBD can also alter its effectiveness. Full-spectrum products, for example, are more likely to produce noticeable effects because of the interaction between CBD and tetrahydrocannabinol (THC), which is known as the entourage effect.

It’s important to point out that stronger full-spectrum gummies also come with a greater amount of THC, which can increase your risk of experiencing side effects.

Keep reading to learn more about the strongest CBD gummies and how to safely use them.

We selected these CBD gummies based on criteria we think are good indicators of safety, quality, and transparency. We looked specifically at gummies that were 25 mg per serving or higher, but all the gummies we selected offer a strong 100-mg option.

We also tested the gummies ourselves to provide feedback on taste and the effects we felt.

As a part of our vetting process, we consider:

  • the product’s composition, ingredients, and overall quality
  • any third-party certifications
  • the company’s reputation and business practices
  • any lab test results
  • marketing claims

How we vet CBD gummies

Our Medical Standards and Insights team has carefully researched and vetted over 11,000 products and services. We fact-check health claims, evaluate ingredients, and look into each brand’s reputation before sharing products and services on Healthline.

To choose the products on this page, we considered all the CBD gummies that passed our vetting process. Then, we personally tested some of them to narrow down our list even further. Read more about how we test CBD products.

Aside from potency, here’s what to consider when shopping for the strongest CBD gummies.

“Watch for marketing that makes medical claims, particularly if it refers to specific medical conditions that CBD does not have FDA approval to treat. The FDA can provide warning letters to these companies that give medical claims to products that are not FDA approved.”

CBD source

There are three forms of CBD to choose from: isolate, broad-spectrum, and full-spectrum.

CBD isolate contains no cannabinoids other than CBD and is a good option for people who want to steer clear of THC. But because CBD isolate products don’t contain the full range of terpenes, cannabinoids, and flavonoids, they may not produce as strong an effect as products that do.

Full-spectrum CBD includes all the cannabinoids along with THC, which helps produce the entourage effect. U.S.-grown hemp can’t contain more than 0.3% THC legally, but it’s still a good idea to read labels and check a product’s certificate of analysis (COA) to make sure there isn’t more THC than listed.

Broad-spectrum products typically contain some cannabinoids but no THC.

Ingredients

CBD gummies might also contain other ingredients like flavorings and sweeteners. Some may also contain added ingredients like vitamins, but there’s not enough research to say that mixing CBD with vitamins and supplements is safe.

If you’re vegan or have any other dietary restrictions, make sure to check the ingredient list.

You’ll want to look for gummies that contain nonsynthetic, organic ingredients.

COA

If no COA is readily available, that’s a red flag. The Food and Drug Administration (FDA) doesn’t regulate CBD like it does prescription medications, so it’s kind of a Wild West out there.

A COA indicates that a product has been tested for contaminants by a third-party lab and that the label is accurate.

“Cannabis has a biphasic effect which means that CBD can offer different effects at low and high doses. As you increase your dose over time, there becomes a therapeutic ‘sweet spot’ giving you optimal effects.

“However, as the dose goes beyond that spot the benefits are lowered. As a result, more consumption does not mean that it will provide a greater effect which can actually diminish that effect over time.

“With cannabis consumption, less is generally more and is a golden guideline I share with individuals that explore this journey.”

— Dominique Fontaine, BSN, RN, HNB-BC, HWNC-BC, integrative nurse specialist

Many studies looking into the effects of CBD involve higher doses.

A 2017 study found that CBD doses of between 300 mg and 600 mg helped decrease anxiety related to public speaking.

However, the researchers of a 2019 study looking at the effects of CBD on sleep point out that lower doses seem to produce enough of a clinical effect, and higher doses in the hundreds of milligrams are cost-prohibitive.

Keep in mind that what works for someone else might not work for you. Some people may respond well to lower doses without needing to try higher potency products.

It’s also important to note that CBD isn’t a cure-all, and it may not produce any effects for you. More research is necessary to fully understand the benefits and full range of effects that CBD can provide.

You likely don’t want to take a 50-mg gummy when trying CBD for the first time. It’s a good idea to work your way up to stronger gummies. You may even discover that a lower dose does the trick.

CBD won’t get you “high” like cannabis, which contains higher amounts of THC. But it may still produce side effects, especially at higher doses. Possible side effects include:

  • nausea
  • changes in appetite
  • changes in weight
  • diarrhea

There’s also evidence that ingesting CBD can affect medication absorption. In addition, taking CBD with high fat meals may heighten the risk of side effects by increasing your CBD blood concentration.

Always talk with a healthcare professional before taking any over-the-counter supplement, including CBD.

For 1 serving of CBD gummies, 300 mg is extremely strong. However, if referring to the amount of CBD in the whole container, this potency is much more moderate.

If there are 30 gummies with a total of 300 mg in one container, that’s about 10 mg per gummy, which is much lower than the strong CBD gummies on our list above.

CBDfx, Cornbread Hemp, and Aspen Green all offer 100-mg gummies, which is the highest strength gummy we have found. The second strongest CBD gummy is 50 mg and is more common for brands to offer.

If you’re ready to try high potency CBD at 50 mg per serving, Cornbread Hemp Organic Berry CBD Gummies is a good option. It’s been a favorite in our testing since 2022. Be sure to start with half a gummy to see how that affects you.

The best CBD strength will depend on the type of CBD and what you are using it for.

For example, someone with a low body weight who is new to using CBD may not need as much as an experienced CBD user who has a higher body weight.

What you’re using CBD for matters as well. Some people will find that a mild or moderate strength CBD of 10 mg to 25 mg makes them feel relaxed or helps them to drift off to sleep. Someone managing chronic pain may need something stronger.

What dosage will work best for you will likely require some trial and error.

Generally, it’s advised to start with a lower dosage of 20 mg to 40 mg and then increase by 5 mg until you find the right strength for you.

High potency gummies typically range from 25 mg to 50 mg per serving. But it’s important to note that what’s strong for one person may not be for another.

A higher dose may be what you need to see noticeable effects from CBD, but keep in mind that it’s best to start small, especially if you’re new to CBD.

Always talk with a healthcare professional before adding CBD to your routine.

Is CBD legal? The 2018 Farm Bill removed hemp from the legal definition of marijuana in the Controlled Substances Act. This made some hemp-derived CBD products with less than 0.3% THC legal at the federal level. However, CBD products containing more than 0.3% THC still fall under the legal definition of marijuana, making them illegal at the federal level. Some states have legalized CBD, so be sure to check state laws, especially when traveling. Also, keep in mind that the FDA has not approved nonprescription CBD products, and some products may be inaccurately labeled.
