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. 

There are many scammers and multi-level marketing salespeople that use Facebook and other social media outlets to push a particular product. Many of them will tell you whatever you want to hear to get you to buy from them. Be wary of their claims and testimonials. It’s particularly important to buy CBD oil from a brand that makes third party lab reports readily available. This third party certification is the only way for you to truly know what is in the product.
NuLeaf only offers one concentration of CBD oil, 50 mg/ml, and the ingredients are as simple as it gets: USDA Certified organic hemp oil and full spectrum hemp extract. NuLeaf essentially has only one product. But this strategy allows them to keep their prices reasonable and offer bulk buying options—you can buy a bottle of NuLeaf CBD oil containing 240 mg total CBD all the way up to 4,850 mg.
Along with PureKana and CW Hemp, I would say that Green Roads CBD oil probably rounds out the top 3 most popular hemp companies selling online, and that would generally translate to status as the “best CBD oil,” right? They have an incredible web presence, and in fact run a really great blog that you should keep up with if you’re interested in the latest CBD news, trends, etc. They’re also big into offering loads of different product, including pre-dosed pens called “Daily Doses,” CBD terpenes, edibles, and even potent CBD concentrates that you can dab (I don’t have a dab rig myself, but I have friends who say the potency is incredible). Honestly, you’ve just got to check out their website in order to get a better idea of the huge range of products they’ve got — all of which are of the highest quality.  
Given CBD’s reputation as a popular, artisanal remedy, one would think that Epidiolex would command a lot of “off label” attention. After all, physicians often prescribe pharmaceuticals off label to treat conditions that were not the actual focus of clinical trials. But the costly price tag for Epidiolex (more than $30,000 annually) precludes off label prescribing as well as affordable access for tens of millions of Americans without health insurance.
The majority of users prefer full spectrum products because they provide synergistic benefits of the whole plant. These products include an array of the naturally-occurring cannabinoids and terpenes from cannabis. Full spectrum CBD oil has up to 0.3% THC to produce the “entourage effect.” CBD oil products with zero THC are known as either “broad spectrum” or “isolates.” These products are generally preferred by those who want to use CBD but either have an aversion to THC or concerns about drug testing.
The human body has an endocannabinoid system — a natural system that maintains homeostasis or balance, in the body. The endocannabinoid system has CB1 and CB2 receptors. These are found throughout the body. CB1 receptors are generally located in the central and peripheral nervous system and CB2 receptors are generally found in the brain, immune system, and gastrointestinal system. CBD binds to these receptors creating changes and effects in the body

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). 
To obtain the CBD-packed hemp extract from its organic crop, Highland Pharms uses a process called “supercritical CO2 extraction.” This method eliminates the need for more harmful solvents, while it also, the company says, yields CBD oil of an outstanding purity and efficacy. Those wanting to see for themselves can take their pick from Highland Pharms’ positively reviewed variety of tinctures – the strongest concentration of which measures up at 1,250 mg – as well as capsules and edibles. And if those potential customers have no idea exactly how much CBD they should be imbibing, then they can get themselves up to speed at the Texas-based company’s website, which offers a user-friendly guide to serving sizes and methods of CBD oil intake, among other common queries.
In your internet travels, you may also come across products called “terpsolates.” The manufacturers of these products infuse CBD Isolate with terpenes (but not cannabinoids like THC). These terpenes may enhance the effectiveness of CBD — or maybe they just make it smell good. This may be a good place to point out that not all CBD products are created equal. The industry is still largely unregulated, and the quality and quantity of CBD in a given product will vary wildly. Third-party testing definitely helps to monitor companies’ claims, but it’s still up to you as the consumer to do your homework on the best CBD products.
Success stories like Oliver’s are everywhere, but there’s not a lot of data to back up those results. That’s because CBD comes from cannabis and, like nearly all other parts of the plant, is categorized by the Drug Enforcement Agency (DEA) as a Schedule 1 drug—the most restrictive classification. (Others on that list: heroin, Ecstasy, and peyote.) This classification, which cannabis advocates have tried for years to change, keeps cannabis-derived products, including CBD, from being properly studied in the U.S.
The vast majority of CBD oils come in bottles measuring either 15 milliliters (mL), or 0.5 ounces; or 30 mL, or 1 ounce. However, CBD concentration is more important than bottle size. Concentration refers to the ratio of hemp oil solution (measured in mL) compared to the amount of CBD cannabinoid (measured in milligrams, or mg). A 15-mL bottle may contain 100 mg of CBD, 300 mg, 500 mg, or more. The higher the mg amount, the stronger the CBD oil will be. For this reason, the ‘mg’ measurement is also referred to as the oil’s strength; i.e., 400-mg oil might be called 400-strength oil.
It’s safe to say that Charlotte’s Web is probably the most recognized CBD brand out there — and it’s not all hype. This company pioneered the CBD industry and made it their mission to de-stigmatize CBD by setting the bar high for transparency. They produce and oversee their organic CBD products from seed to sale, standing behind them with a solid return policy. 
CW Hemp’s Charlotte’s Web strain of hemp came to national attention in 2013 after it was featured on a CNN segment telling the story of Charlotte Figi. Figi has Dravet syndrome, a form of epilepsy; CNN has reported, however, that after the girl began to take CW Hemp’s CBD oil, her seizures radically reduced in number. A touching update to Figi’s tale can be found on CW Hemp’s website, where those looking to see how the company’s CBD oil products might benefit them are able to purchase capsules, cream and balm. Frequent customers, meanwhile, can take advantage of the brand’s hemp oil bulk package, which offers five regular-sized bottles of CW Hemp’s bespoke blends for the price of four – making it a more cost-effective way for some to get their daily dose of CBD.
In 2016 Louisville, Colorado-based Bluebird Botanicals was selected as the leading CBD oil company in the U.S. at that year’s Cannabist Awards, and that accolade came only four years after the business’ founding. In that time, though, Bluebird Botanicals has, according to cannabis industry market researchers Brightfield Group, grown to become the third-biggest selling producer of its kind in America. Perhaps that’s down in part to the stringent quality control measures that Bluebird Botanicals maintains – the results of which can be seen when looking at the certificates of analysis for each batch on its website. And the company’s “assistance programs,” created to aid disabled people, veterans and those on low incomes, also speak to an altruistic approach to customer care. People eligible can receive discounts on Bluebird’s classic and signature hemp extracts, vape oil and CBD isolate.

The tricky part is that there's some evidence suggesting CBD works best for pain when combined with a little THC, says Dr. Danesh. "Depending on what type of pain you have, you might be able to do just CBD, but sometimes you need CBD and THC." This makes accessing a product that will actually help you more difficult due to different regulations in each state. In New York, where Dr. Danesh practices, for example, CBD is available over the counter. But as soon as you add THC, you need a prescription.


CBD topicals: Many people take CBD to manage chronic pain. These folks may find  CBD topicals particularly therapeutic, as they can massage the CBD into the skin of the area causing them pain. Dosing can be more imprecise with CBD topicals, and you may need to reapply often to continue feeling the effect. CBD topicals describes a broad category of products including CBD balms, lotions, chopsticks, and creams.
High potency CBD oils are ideal for those seeking a powerful, therapeutic effect. However, many companies only offer CBD oil in low to moderate potencies. Our pick for the highest potency CBD oil is Sabaidee’s Mega Good Vibes 2500mg+ CBD oil. At 88.33mg of CBD per serving, this is one of the most potent CBD oils on the market. And at $0.08 per mg of CBD, it is also reasonably priced. One 30mL bottle packs 2,500 mg of high-quality, full-spectrum, peppermint-flavored CBD oil.
The average person sleeps around 480 minutes each day, that is unless you are one of the 70 million Americans who suffer from one of several sleep disorders. With so many Americans suffering from sleep problems and low sleep quality, it’s not surprising that many sleepers are turning to the sedating effects of CBD to get a good-nights sleep. When suffering from insomnia, your first thought may be to purchase an over-the-counter supplement such as melatonin from your local pharmacy, but let us explain why CBD may be a better choice for your sleep aid needs. 

CBD oil fans who switch between vaping and sublingual use are ably catered for by CBD Drip. That’s because the company sells an innovative range of full-spectrum oils that can not only be mixed with regular e-liquids or vaped by themselves but which may also be added to food and drink or simply applied under the tongue. For individuals who’d rather make up their own CBD oil-infused products, meanwhile, the company even offers concentrate in bulk. And CBD Drip assures its customers as to the purity and efficacy of its merchandise by explaining in detail on the website what is tested for and why; full lab results for many of its goods are also available to view at a click.
In order to determine which companies were included on this best cbd oil list and how they were ranked, each prominent provider on the market (Note: we pulled our list of brands from other established and credible CBD rankings like: this one and this one.) was allocated six individual Rank Scores based on their performance in the following metrics:
When it comes to bang for the buck, Lazarus Naturals is the industry leader. They’ve built a loyal customer base because of their low prices, high-quality products, and compassionate assistance program for those in need. In fact, they’ve been voted the Brand of the Year by members of the CBD Oil Users Group on Facebook for the last 3 years. We particularly like their dedication to posting third-party lab reports on their website by batch. Their 30-day money-back guarantee speaks to the confidence in the quality of their products which clearly makes them one of the best CBD oil brands on the market.
