While there are other factors that distinguish one product from the next, potency is the kicker, determining nearly everything from the price tag of CBD oil to its therapeutic effectiveness.
So, what is considered “strong” CBD oil?
It is possible to find a broad range of CBD products – whether full-spectrum, broad-spectrum or CBD isolate – in different potencies. While there is no single definition of “strong” CBD, most medical marijuana experts consider high potency to be at least 50mg of CBD per 1ml serving.
However, CBD affects each consumer differently. What feels strong to one consumer may not feel as potent to the next consumer. That’s particularly true if you are new to CBD oil. For individuals who are looking for relief, the highest-concentration CBD oil drops may be what they need to get the job done, particularly if they have not noticed significant effects with hemp products that have a low concentration of CBD.
How We Chose the 15 Strongest CBD Oils
Each CBD oil mentioned in this list contains at least 50mg of CBD per milliliter of the oil. There are many high-potency CBD products out there based on CBD quantity, so we narrowed the options down with criteria that depict quality, safety, and transparency. Every product mentioned in this article is made with U.S.-grown hemp, contains less than 0.3 percent THC, and is manufactured by a company that offers proof of effective third-party testing by an ISO 17025-compliant lab.
As part of the product selection process, we considered the company’s manufacturing process and certifications, the CBD potency, and overall product ingredients. We also paid attention to various indicators of brand reputation and user trust, such as whether the manufacturer has been subject to FDA warning letters, consumer reviews, and whether the company makes an unsupported health-related claim.

Is CBD Oil Right for You?
CBD oil is derived from the hemp plant. It has numerous therapeutic benefits, and studies suggest that CBD may help ease the symptoms of various health conditions such as epilepsy, cancer, and anxiety. Most CBD oils contain trace amounts of THC, which is why they will not make you feel high. Remember, THC is the primary psychoactive cannabinoid in weed.
There are many CBD tinctures and oils on the market today, and it’s important to recognize that not all of them are manufactured equally. Currently, there are no over-the-counter hemp products approved by FDA, and some may not be as reliable or effective as others. As mentioned earlier, individuals respond to cannabidiol differently, which is why you should note any positive or negative reaction as you try out CBD oil.
CBD products are generally well-tolerated and safe for consumption. But it is essential to consult with your healthcare provider before taking CBD oil if you are breastfeeding, pregnant, have pre-existing health conditions, or are taking any prescription medication, OTC drugs, or supplements. CBD can potentially interact with various medications, including those that interact with grapefruit. Carefully read the product’s ingredient list if you are allergic to coconut oil or have other possible allergies.
CBD is legal in most parts of the country, but most manufacturers require consumers to be at least 18 years old to buy cannabis-related products.
This product line may not be legal in some countries. Check your local laws regarding the use of marijuana-related products before buying CBD oil. Even when buying online, first confirm with the manufacturer or retailer that they will ship the product to your location, and be sure to also check the local regulations.
