People taking other medications: When side effects are reported, it’s often by this group. CBD appears to have a similar effect to grapefruit on the liver’s ability to metabolize certain drugs, which can lead to adverse side effects. Generally, if a medication has a grapefruit warning, you should avoid taking CBD. Although, if you are on any medication you should talk to your doctor before starting CBD, to ensure you won’t expect any negative interactions.
So let’s get something straight; Mary’s Nutritionals is the sister company of Mary’s Medicinals (actually they’re the same company), which is one of the cannabis industry’s most established names in cannabis CBD oil – that is to say, CBD oil that is extracted from marijuana and only legal in states with medical legalization (and for those with valid MMJ cards). Mary’s Nutritionals is the legal “hemp-based” version of Mary’s Medicinals; they extract their products industrial hemp like all other brands on the list, and thus are able to ship to all 50 U.S. states. Truth be told I don’t have a ton of experience with them because they’re so expensive, but believe me – their “Remedy” line of CBD oils are easily the best products on the market. That is, if you’re ready to splurge the cash on them. Also, they’re the only company we’re aware of that sells a legal CBD transdermal patch that you use like a nicotine patch. I’ve never actually tried it before, but I heard it works incredibly well.
They operate their own hemp farms in Kentucky and Colorado as well as their own lab and product facilities. Customers appreciate their dedication to making quality products at affordable prices. It’s also great to see a company that’s willing to stand behind their products by offering a 30-day money-back guarantee if you’re dissatisfied for any reason.

Having lived with a progressive autoimmune condition for several years and endured horrible side effects from the toxic drugs with little benefit, vaping CBD has given me my life back after just 8 weeks. It has reduced the inflammation caused by arthritis in my hands and feet significantly and has generally made me feel relatively normal and I’ve now started to reduce my pain meds and hope to be off these in the next few months.


The company’s second strength is trust. The CBDistillery has done a lot to build trust with its customers, including transparent, third-party lab testing, quality control over every step of its manufacturing process, and no gimmicks. CBDistillery CBD oil is made using U.S. Hemp Authority-certified, non-GMO, industrial hemp grown in America using natural farming practices.
Brian Peterson has been a CBD consumer advocate and educator since 2013. He is the founder and managing editor of the CBDOilUsers.com website. He's also the lead administrator of the CBD Oil Users Group, the largest CBD group on Facebook. His passion is educating consumers so that they can make their own decisions when purchasing and using CBD products.
And now, onto the thorny issue of legality. The simple answer to the question is yes — if it is extracted from hemp. The 2014 Farm Bill established guidelines for growing hemp in the U.S. legally. This so-called “industrial hemp” refers to both hemp and hemp products which come from cannabis plants with less than 0.3 percent THC and are grown by a state-licensed farmer.

The CBD oil in everything that’s sold by Receptra Naturals is extracted from hemp from family-owned farms in Colorado. And the oil produced by the hemp plants – which are cultivated completely organically – is only taken from the flowering parts to ensure its purity and quality. Those of an environmentally conscious bent may therefore particularly appreciate the company’s offerings, which include CBD oil blends that aim either to boost users’ overall sense of health or, for people who are particularly physically active, to just give them a bit more pep in their steps. The most potent of these oils is, for the record, a 4,000 mg concentrate. But Receptra Naturals’ range also includes a topical cream, a skin-conditioning body butter and a CBD extract blend for pets that, the producer states, may help with anxiety, mobility and digestion in animals.
Customer Service/Shipping: Free 3-7 day shipping for all US orders, with Rush Shipping available. Customer service hours are 10am to 5pm Central Time. SabaiDee offers a 30-day return policy, along with a unique trial program.

Since 2014, NuLeaf Naturals – our Editor’s Pick – has been committed to creating high-quality CBD oil products. As one of the oldest and most reviewed companies in the industry, NuLeaf Naturals has established themselves as a trustworthy CBD manufacturer. All of their products are tested by third party labs and their cannabinoid profile is impressive. They offer a unique range of concentrations for their organic CBD products ranging from 240mg to 4,850mg.


You won’t have to worry about potency with Spruce CBD. That’s because the potency of Spruce’s CBD oils are verified by a third-party testing lab. Spruce carries both regular and high potency CBD oil formulations. Spruce’s regular potency CBD oil contains a moderate dose of 25 mg of CBD per serving while their max potency formulation packs a strong dose of 80 mg of CBD per serving.
Extraction: The method by which CBD oil is processed from hemp plants can be very telling. Some manufacturers extract and process the oil using toxic materials like propane or butane; in most cases, these oils are cheaply priced. Safer extraction and processing agents include ethanol, which cleans the hemp plant of unwanted toxins; and supercritical carbon dioxide extraction, which strips harmful materials from the plant by changing the carbon dioxide’s temperature and pressure settings.

Transparency: Receptra Naturals’ website has a database where you can look up lab reports for their products. The first time we checked, we got some 404 errors for a couple of the lab reports, but these glitches seem to have been fixed since then. We were able to see third-party lab reports for all their tinctures (though, apparently not for their topicals). 
CBD and THC interact with our bodies in a variety of ways. One of the main ways they impact us is by mimicking and augmenting the effects of the compounds in our bodies called “endogenous cannabinoids” - so named because of their similarity to the compounds found in the cannabis plant. These “endocannabinoids” are part of a regulatory system called the “endocannabinoid system”.
*[A couple things of note before I begin the reviews. In order to avoid redundancy and limit repeating myself dozens of times over, be advised that (unless otherwise noted), all of the companies listed below employ standard practices that are used by all of the best CBD oil companies, including things like: solventless CO2 extraction, 3rd party laboratory testing, legal THC limits below 0.3%, shipping to all 50 U.S. states, etc..]

Cutting-edge science has shown that the endocannabinoid system is dysregulated in nearly all pathological conditions. Thus, it stands to reason that “modulating endocannabinoid system activity may have therapeutic potential in almost all diseases affecting humans,” as Pal Pacher and George Kunos, scientists with the U.S. National Institutes of Health (NIH), suggested in a 2014 publication.
CBDOilUsers.com is not paid to include any brand in our list. We may, however, receive commissions from some of the companies if you make a purchase through links on this website. There are no additional costs for consumers and they support our work to educate and inform consumers so they can make the right buying and usage decisions for themselves.
Like Premium Jane, Fab CBD is another newcomer to the industry, and they made this list simply because of how affordable they are. We received some samples quite awhile back, and while they weren’t the most potent products in the world, they absolutely did work and if you were to buy them from the online store they are about 15% cheaper than other top brands. ($79 for a 600 mg bottle compared to the average $95).
There are very few known adverse side effects of CBD. According to this study, CBD is “a major non-psychotropic constituent of cannabis, has multiple pharmacological actions, including anxiolytic, antipsychotic, antiemetic, and anti-inflammatory properties. But if you are looking for a high from CBD, you will not get that because CBD has no psychoactive effects. Do speak with your physician if you are concerned about drug interactions.
“Buying from a reputable manufacturer is crucial, because it matters how the plant is cultivated and processed,” Dr. Maroon says. One clue that a company is cutting corners: too low a cost. Good CBD is pricey—a bottle of high-quality capsules is sold in Cohen’s office for $140. But for many, it’s worth the money. Roth spent $60 on her tiny bottle. But when her energy returned the day she started taking CBD, she decided that was a small price to pay.
It’s also important to select CBD oil products based on your concentration preferences. Some forms of CBD oil – such as vapors and tinctures – normally have higher-than-average concentrations, whereas sprays and topicals tend to have lower concentrations. Remember: higher concentration means more pronounced effects, but not necessarily mean higher quality.
Los Angeles-based PureKana stresses that it extracts the CBD oil for its products from hemp plants that have been cultivated without the use of herbicides, pesticides or other agro-industrial chemicals that may impact upon crops. What’s more, the company states, no solvents go into the extraction process other than carbon dioxide. And to further put potential customers’ minds at rest, PureKana presents the results of third-party testing of its CBD oil tincture on its website – a welcome nod to transparency. That tincture can be found in the company’s own blend of CBD oil drops – the three varieties of which have elicited highly complimentary reviews from users – as well as its capsules and cooling topical ointment. Meanwhile, for anyone with a sweet tooth, PureKana’s CBD isolate-containing gummy bears may just do the trick.
The science behind CBD is in the relatively early stages. As a cannabinoid, we know that CBD interacts with receptors in your endocannabinoid system. The endocannabinoid system is integrated throughout your body — and this widespread, whole-body interaction creates a broad range of effects. Hence, the long list of possible benefits.   We may still be in the early stages of discovery, but there’s plenty of scientific studies and anecdotal evidence that CBD provides relief for an array of ailments. Here’s a non-exhaustive list of some potential benefits of CBD oil:
CBD (Cannabidiol) is a potent, non-psychoactive cannabinoid found in hemp oil. It is typically extracted from industrial hemp plants that are naturally high in CBD and other phytochemicals. It is the most prevalent of over 80 different cannabinoids found in natural hemp. It is commonly used for its therapeutic properties. Cannabidiol is responsible for a wide-range of positive health benefits through its interaction with the body's own endocannabinoid system.
Although CBD oils aren’t regulated by the FDA, purchasing products stateside from one of the nine states where recreational and medical cannabis use is legal will likely result in a higher-quality product than buying one made with hemp-derived CBD oil imported from abroad, says Martin Lee, director of Project CBD, a nonprofit that promotes medical research into CBD.
Green Gorilla marks itself out by simply blending its flagship line of CBD oils with organically produced extra virgin olive oil – and nothing else. And, as the company states, there’s a benefit to this beyond assuring the product’s purity. In particular, olive oil “has synergistic effects in combination with CBD,” and according to Green Gorilla’s website, it’s “also able to deliver the CBD to the parts of [the] body that need it most.” The products are certainly affordable, too: its 150 mg pure CBD oil comes in at $25.99, for instance, making it a smart choice for new users. And anyone still uncertain about the potential effects of Green Gorilla’s products may have their questions answered by the convenient “science” section of the manufacturer’s website, which neatly explains the difference between THC – the cannabinoid that makes people “high” – and CBD.
Transparency: cbdMD seems to be going through a transition with their third-party testing practices. Until recently, they only released a lab report for the CBD concentrate they use for all their products, but would not show potency testing for individual products. That seems to be changing. Currently, the only lab report on the website is for their concentrate (and it’s over a year old). But if you contact customer service, they’ll send you a lab report for any product. 
A newcomer to our CBD oils ranking, RE: Botanicals is no stranger to hemp. Founded by John Roulac, a long-time hemp advocate and founder of the organic superfoods brand Nutiva, RE: Botanicals is one of the only CBD brands to earn the USDA organic seal. They deserve a shout-out for prioritizing regenerative agriculture, while keeping prices reasonable.   
Nearly every expert Health spoke to agreed that your CBD products should be tested by a third party to confirm the label's accuracy. This is a real concern in the industry—take the 2017 Journal of the American Medical Association study, for example, which tested 84 CBD products and found that 26% contained lower doses than stated on the bottle. Look for a quality assurance stamp or certificate of analysis from a third party (aka not the actual brand) or check the retailer's website if you don't see it on the product's label.

Sabaidee’s high potency CBD oil is made with just four simple, natural ingredients: CBD-rich hemp extract oil, MCT oil from coconuts, peppermint oil, and stevia leaf extract. The peppermint and stevia give this CBD oil a sweet and minty taste that’s not overpowering. Each product batch is tested by an independent third-party laboratory for purity and potency. And if you like the sound of Sabaidee’s CBD oil but are looking for a lower potency option, low and moderate potencies (8.33mg and 33.5mg per serving respectively) are also available.
CBDPure oils are made with non-GMO hemp, grown in Colorado by local farmers. Our hemp oil is minimally processed by following the highest organic standards at every step of our growing, harvesting, and bottling process. When you buy a CBDPure product, you are buying the purest CBD oil from natural sources, that is 100% free of any synthetic or artificial ingredients. We test every batch of oil that we process to ensure that it meets the purity standards that we demand.
Cannabidiol (CBD) is a naturally occurring compound found in the resinous flower of cannabis, a plant with a rich history as a medicine going back thousands of years. Today the therapeutic properties of CBD are being tested and confirmed by scientists and doctors around the world. A safe, non-addictive substance, CBD is one of more than a hundred “phytocannabinoids,” which are unique to cannabis and endow the plant with its robust therapeutic profile.
