Here are 10 of the best potent options and hands-on reviews of Batch and Nuleaf Naturals oils.
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 federally legal. However, CBD products containing more than 0.3% THC still fall under the legal definition of marijuana, making them federally illegal but legal under some state laws. 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.
Below are some examples of high strength CBD oils and tinctures .

MNT's review
This tincture holds USDA organic certification and uses Colorado-grown hemp. It comes in a 1 fl oz bottle with an enclosed dropper. Each bottle of this full-spectrum product contains 3,270 mg of cannabinoids, which includes 3,000 mg of CBD, 75 mg of THC, and other cannabinoids, such as CBN, CBG, cannabichromene (CBC), and cannabidiolic acid (CBDA).
The dropper has graduated markings at .25, .50, .75, and 1 mL. A 1 mL serving is equal to ¾ of a dropper. A 1 mL serving provides roughly 100 mg of CBD, 2.5 mg of THC, and 6.5 mg of other cannabinoids. The company claims this oil’s THC content is within federal guidelines of less than 0.3% of the product’s total weight.
The tincture features CBD oil derived through the Supercritical CO2 extraction process, which is reportedly cleaner and better for the environment than other extraction methods. Other ingredients include an organic coconut MCT oil base.
It is available in unflavored or with organic citrus and mint flavoring. Organic rosemary extract functions as a preservative.
Because this is such a high-strength product, the manufacturer recommends starting with a low dose and increasing gradually.

What our tester says “I tested the product at different times of the day to see how it impacted my mood / stress. When I took it at night, I paid attention to how sleepy it made me.
“All three of the oils had a hemp-y taste to them. Citrus was my favorite of the three because it hid that taste the best in my opinion. The mint was refreshing, but I am just not a mint fan.
“I really enjoyed this product! When I first tested the product, I followed the recommended dosage instructions (1 mL/1 full dropper and held the product in my mouth for 120 seconds). It took about 40 minutes to start feeling the effects, and they lasted for several hours. As a beginner, I learned that I should have started with about half a dropper instead of a full one.
“The strength of the effect I felt ebbed and flowed throughout the day, with a peak around 4–5 hours in. During the peak, I felt a little slow or sluggish, which is great before bed but not during the day. When I reduced the dosage to a half dropper, the strength of the effect was perfect to me for daytime use. I was able to work a productive day while feeling very little stress, a rarity for me. I took some oil before seeing family over the holidays, which also made the experience more stress-free.
“I do not experience chronic pain, so I was unable to note any improvements. I do, however, have a really hard time falling asleep. When taken at night, I found it much easier to fall and stay asleep for a full night. I occasionally took the full dosage before bed because that sluggishness lent itself well to a very deep night’s sleep. I would recommend taking it about 1 hour before heading to bed.”

This full-spectrum CBD oil is available in doses of 25 or 50 mg per 1 mL. Each 1 mL serving also contains either 0.5 or 1 mg of THC.
This oil is only available unflavored. It contains organic hemp flower extract and organic MCT coconut oil. According to the company, it has a smooth and mild flavor.
Cornbread says that only using cannabis flowers increases the amount of cannabinoids and reduces the amount of chlorophyll in the product. The company states that other manufacturers may use stems, leaves, and stalks, which may reduce the quality of the oil.

What our tester says “I tried this oil to relieve muscle pain. I recently had chronic pain in my left shoulder stemming from a nagging rotator cuff injury sustained while surfing. I was in pain every day and it affected my quality of life. The pain altered my sleep for the worse, and I couldn’t swim or surf — my daily form of exercise.
“No amount of physical therapy or prescription drugs were providing lasting relief. This CBD oil was the only thing that blocked the pain. Although it was a new type of physical therapy, proprioceptive-deep tendon reflex therapy, that cured my pain, this CBD not only relieved the pain, it helped improve my mood, which was suffering from being in constant pain.
“CBD is not a miracle cure, but it can help relax your muscles and block the pain signals. I take CBD after I surf, and I’m feeling rejuvenated.
“I’d recommend it to Medical News Today readers as it’s a product from a trusted brand, and I found it effective for easing chronic muscle pain. I think it would best suit an experienced CBD user who needs strong relief, but not a maximum strength dose.”

What our tester says “Having tried Batch CBD’s Calm Oil, which I loved, I was eager to try this more potent, full-spectrum Gold Reserve Oil.
“I used the product late afternoon or early evening when I had completed meetings for the day and needed to get into a productive and focused work groove for the next few hours. I wanted to ease into the late afternoon/evening and take the edge off from the day, but still wanted to be fresh and focused enough to finish up tasks and to-dos from the day. This was perfect.
“This oil worked really well for me. I took slightly over half of the recommended dose, which is 0.5 mL. Because it’s described by the brand as a “heavy-hitter” that’s “not meant for rookies,” I wanted to ease into it. On days where I was feeling edgy or tapped out due to back-to-back meeting marathons and too much morning caffeine, this was a great reset. It allowed me to wind down yet feel fresh and focused.
“The taste is very subtle and just very slightly earthy and citrusy — quite pleasant. The Batch website describes it as having a “slightly citrus flavor,” which I’d say is spot on, but it tastes very natural.
“The oil had a very slight citrus smell — I honestly didn’t even notice it at first.
“I would recommend it [to MNT readers], though I agree with the brand’s description that it’s potent, so buyers should be aware.”

Before people select CBD oils, they can research different products to find one that is safe and reliable. Customer reviews from third-party sites, such as the Better Business Bureau (BBB) and Trustpilot , are useful for researching brands.
Individuals may want to review each product’s ingredient list and concentration levels to ensure it is safe and suitable for them. It is important to check for potential allergens in the full ingredients list.
Additionally, people can check if their chosen product is lab-grade and third-party tested.
A person using CBD for the first time may find a product with a lower dosage more suitable. They can then gradually increase the dosage as desired.
Read our complete CBD buyer’s guide or learn how to buy the best CBD oil .
According to a 2021 review , CBD can negatively interact with medications, such as anticonvulsants, including diazepam , lamotrigine , and phenytoin.
People should also not use CBD alongside sedative drugs, such as barbiturates , and narcotics, such as codeine and morphine. Anybody taking medication can speak with a qualified healthcare professional before taking CBD.
CBD can make people drowsy, so people should avoid driving and handling heavy machinery when taking this product.
A person taking CBD for the first time may avoid strong CBD. It is better to start with a lower dose and increase the dosage slowly. However, people may avoid exceeding a brand’s recommended dose on their products’ packaging.
A person can always speak with a healthcare professional before using CBD products.
While there is a wealth of research regarding the effects of cannabis and THC, few high quality human trials are investigating CBD alone.
It is difficult for experts to predict precisely how differences in strength affect CBD’s effectiveness.
Based on the findings of a 2020 review , CBD appears relatively safe at various doses. However, the authors did not pinpoint a specific dose or range of doses they believed would benefit everyone.
Most of the studies included in this review evaluated daily doses of 300–600 mg of CBD, but a few studies reported using doses as high as 2,000 mg per day.
Everyone responds differently to CBD, so it is best for people using CBD to start at a lower dose for the first time.
Purchasing a product with a higher CBD concentration may be more cost-effective and convenient for some people.
For example, someone who uses 300 mg of CBD for chronic pain or anxiety would use 12 full droppers of 25 mg of CBD oil. They could get a similar 300 mg dose by using only one and a half droppers of 2,000 mg CBD oil.
However, stronger products may provide more CBD per unit but may lead to inaccurate dosing.

CBD does not appear to cause any significant side effects, even at doses above 150 mg per kilogram (kg) of body weight.
However, the Food and Drug Administration (FDA) warns that using CBD products may produce the following adverse effects:
drowsiness gastrointestinal problems diarrhea decreased appetite mood changes, such as irritability liver injury (with certain drug interactions) interactions with alcohol and other drugs The FDA has approved only one CBD product, called Epidiolex , which is for severe forms of childhood epilepsy. The FDA does not regulate any other CBD products.
Learn more about the side effects of CBD .
Label accuracy People can avoid purchasing products from companies that have inaccurate labeling. The FDA has a database of CBD companies to which it has issued warnings, as the content did not match the amount of CBD on the product’s labels.
In a 2022 study , researchers found that nearly half of the 80 CBD products it looked at that were available for sale in central Kentucky had inaccurate label information.
However, most reputable CBD manufacturers will provide third-party lab results to their customers.
People can always use caution when shopping for CBD, especially high potency products. High potency CBD products can be inaccurately labeled. Some products may not even contain CBD.
Some CBD products may also contain enough THC to produce a positive result in a drug test.
Learn more about THC and drug tests .
A person can always speak with a healthcare professional before trying any supplement, including CBD oil, especially if they are currently taking medication. If they are considering taking CBD for a particular health problem, such as sleep issues, anxiety, or pain, they can speak with a doctor to make sure it is a suitable supplement to try.
If they experience side effects after taking CBD, they can stop using it and contact a doctor.
What is the highest strength CBD oil on the market? What kind of CBD gets you the highest? THC is the psychoactive compound in the cannabis plant that causes euphoria or a “high.”
CBD is only federally legal if it has a THC content of 0.3% or less. This amount of THC will not cause psychoactive effects, so CBD should not get people high.
However, it is always a possibility that CBD products have inaccurate labeling. It is important to only purchase from reputable companies such as the ones we list in this article.

Which type of CBD is the strongest? Full-spectrum and broad-spectrum CBD oils may affect the body more than CBD isolate. Full-spectrum and broad-spectrum CBD contain a range of cannabinoids, flavonoids, and other compounds that work together to increase the effect of the product on the body’s endocannabinoid system, which people call the “entourage effect.”
