CO2 extraction is one of the most common ways CBD is extracted from the hemp or cannabis plants. This method uses expensive equipment that adjusts temperature and pressure to extract the cannabinoids from the plant material, without damaging them. The other common method is to use solvents like ethanol or butane to extract the plant material. These solvents have to be burned off the final product which may damage the cannabinoids or terpenes in the process. There is also a risk that these solvents may not have burned off completely and could end up in your end product.
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.
Buying online is less reliable still because there’s no regulation or standardization. What you see on the label may not be what you are getting. A 2017 study in JAMA found that of the 84 CBD products researchers bought online, 43 percent had more CBD than indicated, while 26 percent had less, and some had unexpected THC.“There’s a 75 percent chance of getting a product where the CBD is mislabeled,” says Marcu, one of the study’s coauthors.

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:
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.
Unlike THC, CBD will not make you high. That said, this doesn’t mean CBD is not at all psychoactive, as many assert, says Jahan Marcu, PhD, director of experimental pharmacology and behavior at the International Research Center on Cannabis and Mental Health in New York City: “CBD does change cognition. It affects mood, which is why people take it for anxiety. And some find that it makes them more alert.”

Charlotte’s Web is currently one of the top CBD hemp brands in the U.S and is constantly featured on top authority websites such as The Wall Street Journal, Time and The Huffington Post. What started off as a hemp strain packed with CBD to help a girl named Charlotte Figi, soon turned into an empire. Today, Charlotte’s Web, formerly known as CWhemp offers a wide range of high-quality products including oils, capsules and even CBD gummies.

NuLeaf Naturals markets themselves as “the world’s premier CBD oil company” – I don’t know if I’d quite go to that extent and say that, but I will say that my partner Josh and I have both tried their full-spectrum tinctures, and they do work incredibly well. Also, they main reason they made it on my list here of the best CBD oils online is the fact they offer one of the most potent oral tinctures on the market: a 1,450 mg super highly concentrated oil that wiped my back pain out in less than 20 minutes. To be clear, that’s 45% more potent than PureKana’s strongest oil (1,000 mg). Why don’t I use NuLeaf Naturals all the time then, you might be wondering? Well, I can get away with much smaller doses than that, so there’s no reason to take such a potent dose if I don’t need to. If you’ve been scrounging around the web trying to find a super strong CBD oil, or have otherwise not had great results with other products, I definitely recommend trying some of NuLeaf Naturals’ stuff out. Be advised, though, that it ain’t cheap!
Being more a traditional gal, it’s kind of funny that I like Hemp Bombs CBD so much. Judging by their Instagram and so forth it seems like they’ve made an effort to appeal to a younger, more “hip” crowd, but I don’t care – they sell some darn good CBD products and that’s the only thing that matters to me. And actually, if you’re into vaping CBD oil or prefer to use a CBD vape pen, they’re definitely the company that I would recommend the most. I’m not huge into vaping myself, but they’ve got a MASSIVE range of high-quality (and highly potent) CBD vape products in addition to the standard stuff like oral tinctures and CBD capsules. My partner has even used the “Sugar Cookie Kryptonite” vape liquid and absolutely loved it! Really, you’ve got to just spend some time browsing their store to come to terms with the huge range of products they’ve got: CBD “Pain Freeze,” CBD “Max Chill Shots,” and even a brand new product called CBD Beard Oil!!
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.
What exactly is cannabidiol (CBD) and more importantly, what does it do? Those questions and more are at the heart of this comprehensive guide to one of the most fascinating and important compounds of the cannabis plant. Cannabis plants are chemical powerhouses that produce more than 400 different compounds. Not all of those compounds are unique to marijuana, of course, and appear in many other species of plants. That’s why marijuana can smell like pine trees or taste like fresh lemons. But of those 400 compounds, more than 60 of them are totally specific to the plant genus Cannabis. Scientists call these special compounds “cannabinoids.” However, not all cannabinoids are created equal. One of them, cannabidiol, or CBD, holds the key to the wide variety of medicinal and therapeutic effects marijuana offers.
The main thing that is inherently clear when scouting out FabCBD (which is a super new brand by the way that only just got started this year), is that they’ve made a pretty serious effort to develop a modern lifestyle brand. If you take a look at their website, everything from the web design to the brand labeling to the text they use screams modern and hip.
There’s no definite amount that’s appropriate for everyone, but the ratio of CBD to THC will indicate how psychoactive the product is and if it’s legal in your state. The more CBD compared with THC, the less of a high, and vice versa. “Managing psychoactivity is key to successful cannabis therapy,” says Lee. “Amounts should be made clear on the label and lab-certified so people know what’s helping them and what’s not.”
Pregnant or breastfeeding women: Because researchers don’t want to put the mother or fetus in danger, clinical studies typically don’t include pregnant and breastfeeding women. As a result, physicians can’t definitively say whether or not CBD is safe for expecting and new mothers. Not enough research has been done. However, one study did find that CBD increased the permeability of the placental barrier, which could put the fetus at risk.

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.

Scott Shannon, MD, assistant clinical professor at the University of Colorado, recently sifted through patient charts from his four-doctor practice to document CBD’s effects on anxiety. His study, as yet unpublished, found “a fairly rapid decrease in anxiety scores that appears to persist for months,” he says. But he says he can’t discount a placebo effect, especially since “there’s a lot of hype right now.”
Is CBD Legal? Hemp-derived CBD products (with less than 0.3 percent THC) are legal on the federal level, but are still illegal under some state laws. Marijuana-derived CBD products are illegal on the federal level, but are legal under some state laws. Check your state’s laws and those of anywhere you travel. Keep in mind that nonprescription CBD products are not FDA-approved, and may be inaccurately labeled.
Tinctures – Typically tinctures are small glass or plastic “dropper” bottles that have cannabidiol oil mixed with a preserving solution such as alcohol. Tinctures were very a very common way to ingest botanical oils prior to the industrial revolution and are experiencing a resurgence in popularity as more people are looking for natural remedies. Tinctures with droppers allow you to put a few drops in your tea, under your tongue, or to bake the oil directly into your food.

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.
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).
When it comes to CBD oil, NuLeaf Naturals is practically a veteran of the industry. Founded in 2014, this company has been offering simple, no-nonsense legal CBD for five years. NuLeaf uses specially bred therapeutic hemp plants that contain high levels of CBD and other beneficial cannabinoids like CBC, CBG, and CBN while maintaining low levels of the psychoactive cannabinoid THC.
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.
