Along with PureKana and Premium Jane, MedTerra CBD is one of the few companies that has a commercialization agreement with hemp farms under the Kentucky Pilot Research Program. My partner and I really like this brand because it’s clear that they’re much more focused on health and science rather than creating gimmicky promotions and web advertisements to try and build their “brand.” The CBD industry definitely needs more companies with this mentality. We haven’t tried them a whole lot, but we did receive a couple of samples of their “Medoil Tinctures,” and they worked particularly well for my partner’s anxiety and sleep issues. They also were OK for my back pain, but not quite as potent as some other brands I’ve used.
This means high doses of CBD could significantly decrease the metabolization of cocaine. In fact, a study done on mice found exactly that 11. But what they also found was that CBD only significantly decreased the metabolization of CYP substrates like cocaine, when taken in extremely high doses off 30mg/kg. Such a high CBD dose far surpasses the currently maximum recommended dose of 1500mg/day.
Through its regularly updated and highly informative blog, Koi CBD goes the extra mile to help its customers learn about new developments in the field of CBD use. The company also helps its patrons out by publishing full lab results on each of its products, helping CBD oil users know exactly what to expect. And those purchases may include Koi’s bespoke full-spectrum CBD oil blend, complete with fellow cannabinoids CBDV, CBN and CBG – the inclusion of which, the company claims, “provide[s] the ultimate experience in CBD.” Also available to buy from Koi’s website are a range of 1,000 mg vaping liquids, lavender-scented body lotion, tropical-flavored gummies and, for canine CBD lovers, chewable treats.
Cannabidiol (CBD), a non-psychoactive segment of the marijuana plant, has created huge enthusiasm among researchers and physicians. CBD Oil applies its remedial effect on an atomic level is as yet being sorted out. Cannabidiol is a pleiotropic sedate in that it produces numerous impacts through various atomic pathways. CBD Oil acts through different receptor-free channels and by official with various non-cannabinoid receptors and particle channels.
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).
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:
Very much needed information! I’m a disabled Veteran with Anklyosing Spondelitis and related skelital/ muscle issues and CBD has been an off-limits product with the VA chronic pain clinics that dispense opiates… until recently with the addition of 0% THC – Thank you for the option!! (We actually have to sign a letter stating we will not use… else when we get tested at every appointment and THC is detected, we could be ejected from the pain clinic and our use of opiates for chronic pain!)
Over the last couple of years, CBD oil has become a popular form of treatment for pain management. While CBD is not yet FDA-approved for pain relief, more and more doctors are looking into it. The major advantage of CBD oil compared to traditional cannabis is that it doesn’t cause the “high” feeling. Under updated hemp legislature in the 2018 U.S. Farm Bill, CBD is sold in all 50 states.
Yes, the words “CBD tincture” and “CBD oil drops” are used interchangeably to describe drops of CBD oil that users place under the tongue. For optimal results, we recommend that you hold the drops under your tongue for up to 60 seconds. This process allows the CBD oil to absorb sublingually into your bloodstream through the mucous membranes in your mouth.

Unflavored hemp oil has a strong grassy and earthy taste. Some people enjoy the taste of natural hemp, but it’s not particularly popular. If a shot of wheatgrass sounds like a terrible idea, you’ll probably want to gravitate toward something with a more…palatable flavor. If you’re not sure, you can always start with a simple flavor you know you’ll enjoy, like mint or lemon, and get more adventurous over time.
But even though it's infiltrating pretty much every corner of the wellness world (hi, vegan CBD brownies!) many people still find CBD a little confusing—especially when it comes to figuring out the right way to use it and how to make sure the stuff you're buying is, you know, actually legit. Below, we asked experts to answer the most pressing questions about CBD.
We’d be lying if we said costs didn’t matter. As in all things, with CBD oil tinctures you generally get what you pay for. Some of the products we recommend below are small and inexpensive (so you’re not sacrificing quality to buy inexpensive CBD oil, but rather, are just getting a smaller overall amount at once). Other products contain a higher potency formula, so even though the amount of liquid in the bottle may be the same, the amount of cannabinoids will vary greatly. Overall, prices range from as low as around $30 to over $400.
Customer Service: There are multiple ways to get in touch with customer service, and Pure Hemp Botanicals’ customer service representatives are both quick to respond and forthcoming with information. On the down side, free shipping kicks in at $100 — otherwise it’s a pricey $9.99 flat rate. And you can return products, but only if they’re unopened.

This is a confusing one for many people. "A lot of brands don't do a good job of clearly instructing their consumer on the dosing," says Chris Roth, CEO and co-founder of Highline Wellness. When thinking about dosing, also consider whether your CBD is full-spectrum or isolate: Full-spectrum could include other cannabinoids like cannabidivarin or cannabigerol (this is important, since "there's something called the 'entourage effect' when all together, they're more effective than any one of them alone," Roth explains), while isolate is 100% CBD. "Some people might only need 10 milligrams of full-spectrum CBD, but with isolate, even taking 80 or 100 milligrams might not have the same effect," he says.
All this talk about THC lands us nicely in the whole “Full Spectrum vs. Pure Isolate” debate. Once you begin shopping for CBD products, you’ll notice a lot of jargon that gets thrown around without much explanation. Now that we’ve introduced THC into the conversation, we can talk about the difference between, and relative benefits of, Full Spectrum CBD and CBD Isolate (and the lesser-known contender: Broad Spectrum).

In addition to acting on the brain, CBD influences many body processes. That’s due to the endocannabinoid system (ECS), which was discovered in the 1990s, after scientists started investigating why pot produces a high. Although much less well-known than the cardiovascular, reproductive, and respiratory systems, the ECS is critical. “The ECS helps us eat, sleep, relax, forget what we don’t need to remember, and protect our bodies from harm,” Marcu says. There are more ECS receptors in the brain than there are for opioids or serotonin, plus others in the intestines, liver, pancreas, ovaries, bone cells, and elsewhere.
Of course, though, they offer less potent oils than that, with a product lineup that ranges from 300 mg CBD per bottle to 4,000 mg. Naturally the 4,000 mg option is the most expensive (this is the one that provides the “bomb” 60 mg dose), as it currently sells for $299. For long-term pain and anxiety relief, though, it may be well worth it if it is effective for you and helps replace your regular meds.

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.


“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.
Non-THC CBD oils can be highly effective, and are suitable for employees who face random or routine drug tests. Our top pick for this category is the Medterra CBD Oil Tincture, which contains 99.6% CBD and MCT oil (also known as coconut oil extract) without any traces of THC. The oil is derived from hemp plants that are free of GMOs and pesticides, as well. All third-party testing results for the oil are accessible through Medterra’s official product page.
Most human studies of CBD have been done on people who have seizures, and the FDA recently approved the first CBD-based drug, Epidiolex, for rare forms of epilepsy. Clinical trials for other conditions are promising, but tiny. In one Brazilian study published in 2011 of people with generalized social anxiety disorder, for example, taking a 600-mg dose of CBD (higher than a typical dose from a tincture) lessened discomfort more than a placebo, but only a dozen people were given the pill.
Pioneers of the CBD industry, 4 Corners Cannabis helped pave the way for companies that want to provide quality products and utilize best practices. They grow their own strain of hemp and make small batches of true full-spectrum CBD products. Their prices place them lower down on our ranking, but their highly satisfied customers are more than willing to pay for the 4 Corners quality.  
Along with PureKana and Premium Jane, MedTerra CBD is one of the few companies that has a commercialization agreement with hemp farms under the Kentucky Pilot Research Program.

Research on CBD and anxiety has generally looked at cannabis as a whole product including THC, not as CBD as a standalone compound. Some studies suggest that it can help with anxiety: like this 2011 study that suggests CBDcan reduce social anxiety or this 2015 review that says CBD could be promising for many forms of anxiety. It’s also important to consider whether the CBD comes from the cannabis plant and therefore may include THC, a cannabinoid that for some, induces anxiety. Read our comprehensive article on CBD and anxiety, here.
You should only use CBD products if you are willing to accept at least some risk of testing positive on a drug test. Not everyone who uses hemp-derived CBD oil tests positive. But it does happen. The risk of testing positive is lower if you’re using a broad spectrum or isolate product. These products have non-detectable levels of THC based on manufacturer testing.
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.
Insomnia: The anxiety-alleviating and sleep-prolonging qualities of CBD oil make it a good option for many people with insomnia. Those who experience insomnia due to pain or discomfort may also find that using CBD oil alleviates their physical symptoms to a noticeable extent. CBD oil may also promote daytime wakefulness when taken in small amounts; people with insomnia can use it as a pick-me-up if they feel excessively tired due to lack of restful sleep.
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.
Weight plays a role in the effects of CBD oil, and bottle size should be selected based on how much you weigh. Let’s say you weigh less than 130 pounds and desire light CBD oil effects; this means that 11 mg or less will probably suffice per dose, giving roughly 40 doses from a 450-mg concentration. If you weigh more than 230 pounds and desire strong effects, then this same concentration will supply roughly 10 doses.
Currently, the only CBD product approved by the Food and Drug Administration is a prescription oil called Epidiolex. It's approved to treat two types of epilepsy. Aside from Epidiolex, state laws on the use of CBD vary. While CBD is being studied as a treatment for a wide range of conditions, including Parkinson's disease, schizophrenia, diabetes, multiple sclerosis and anxiety, research supporting the drug's benefits is still limited.
Drops (also referred to as tinctures) are the most popular way to take CBD oil. They are typically sold in glass bottles with a built-in dropper. The drops are placed under your tongue and held there for at least 60 seconds. This drop process allows the CBD to absorb sublingually into your bloodstream. Other popular ways to take CBD include vaping, gummies, capsules, and topical creams. How you take it is a personal decision based on your preferences. Many experienced users take multiple different products at the same time.
