If your CBD isn’t working the way you expected, you might want to try something stronger. Our expert shares other tips for trying out strong CBD gummies and how effects can vary by person.

If you’re not experiencing the desired or noticeable effects of CBD at your current dose, high potency cannabidiol (CBD) might be a good fit.

The type of CBD can also alter the product’s effectiveness. Full-spectrum products, for example, are more likely to produce noticeable effects because of the interaction between CBD and tetrahydrocannabinol (THC), 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.

If you’re not ready for the strongest CBD gummies, check out our picks of the best CBD gummies.

For this article, we’ve focused on extra-strength gummies that contain up to 100 milligrams (mg), making them some of the strongest CBD gummies on the market. The products we listed passed our vetting process and underwent testing by our editors.

We also interviewed an expert for tips to keep in mind when trying CBD for the first time and for trying out stronger gummies. Keep reading to learn more about the strongest CBD gummies and how to use them safely.

Slow and steady

The effect of CBD and THC varies by person. Before using max strength, start increasing your dose slowly.

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.

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

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

In a talk with expert Alex Nguyen, PharmD, RPh, CPh, Dr. Nguyen shared some industry standards to look out for when you’re searching for any type of CBD product.

“Avoid CBD products that make exaggerated claims and have no information that supports it … In addition, double check the labeling where they list the full ingredient list along with the CBD and THC content of the product.”

When looking for potency, keep in mind that you can get three types of CBD: full-spectrum CBD, broad-spectrum CBD, and isolates. Make sure to do your research before choosing a CBD product.

“It’s important to understand what your goals are. Are you using CBD for sleep, pain, stress, or something else?” Dr. Nguyen says. “Knowing what you are using it for will determine choosing the right product and how much of it you should be taking.”

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.

If you’re not feeling any effects, Dr. Nguyen recommends playing around with food intake. “The biggest factor that will affect the potency of CBD and THC is how much food you are ingesting prior to introducing CBD or THC to your body. If you don’t eat prior to intaking CBD or THC, the effects may be heightened.”

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 and effect as products that do.

“[Isolates] can be considered a good option for individuals starting to become familiar with CBD,” Dr. Nguyen recommends. “Isolates are less tendent to trigger allergies. In addition, isolates do not contain any THC.”

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.

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.

“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

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.

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:

Dr. Nguyen recommends talking with your healthcare professional before you take CBD, especially if you’re currently taking “benzodiazepines, muscle relaxers, antidepressants, antiepileptics, or blood thinners.”

There’s 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.

Dr. Nguyen states that the highest CBD dose a human can tolerate is up to 1,500 mg per day. Keep this in mind while you’re taking high potency CBD gummies.

The best CBD strength will depend on the type of CBD and what you’re 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 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.

The type of CBD does not determine its strength. How many mg of cannabinoids are in the product determines its strength.

The strongest CBD gummies in this article contain 100 mg of CBD per gummy.

“You can develop a tolerance to the effect over time, but you won’t become completely immune to CBD,” Dr. Nguyen says.

“You may have reached a plateau in dose where you increase the dose and find no additional benefit. Other factors to consider that may affect the effects of CBD are your health, diet, and stress levels. If you find yourself becoming more tolerant to CBD, you may want to consider taking a break for some time before you start again.”

“It is highly dependent on how you are taking it,” Dr. Nguyen says.

“Smoking and inhalation can be between 1 to 5 minutes. Intranasally, it can be between 5 to 10 minutes. Topical creams can take 15 to 30 minutes before you feel any localized relief.

“Lastly, there are edible capsules and gummies that can take 30 to 120 minutes before you feel the maximal effect of CBD.”

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

A higher dose may be necessary to see noticeable effects from CBD, but remember that it’s best to start small, especially if you’re new to it.

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.
