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.
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.

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.  


For those with little understanding of where CBD comes from, how it can affect the body or even what “CBD” stands for, CBDfx has it all covered through the convenient “Knowledge Hub” section on its website. Meanwhile, anyone searching for further answers may just find what they’re looking for on the company’s blog, which investigates, among other subjects, CBD oil’s impact on the ageing process and whether or not the cannabidiol can assist with anxiety. In all, then, CBDfx helps fully equip potential customers with the information they need before they make a purchase. And if they do decide to buy from this provider, they have plenty of choice, too, as its range of products takes in not only CBD oil tinctures, capsules and gummy bears but also a lemon-flavored “Chill Shot” drink – which, the company claims, is “one of the tastiest and most satisfying ways to dose yourself with CBD.”
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.

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.
CBD (short for cannabidiol) is one of at least 113 chemical compounds known as cannabinoids found in the cannabis plant. The popularity of CBD oil products continues to increase as more consumers learn about the potential health benefits. Anxiety, depression, chronic pain, inflammation, and insomnia are just a few of the conditions cited by users who are successfully using CBD products.

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.
This is why Amanda Oliver, 31, a career consultant in Charleston, SC, pops a CBD gummy bear each night before bed. “I used to lie there tossing and turning as my mind raced from work projects to whether I had set the home alarm,” Oliver says. One piece of candy with 15 milligrams (mg) of CBD is enough to shut off her brain and facilitate sleep. She also swears by the CBD oil she takes at the height of her period, which she says quells her debilitating cramps.
Real Scientific Hemp Oil touts itself as being somewhat of a pioneer, as – according to the company – its own variety of CBD oil was the first to hit the mainstream back in 2012. In addition, the brand claims that its RSHO-X CBD liquid is the earliest no-THC product of its kind, making it a sound choice for those worried about whether CBD oil use will influence the results of drug tests. The company is also transparent about the processes that go into making its varieties of CBD-containing hemp oils, helping customers make informed choices as to which of its products are best for them. And minds may be put at ease upon learning that Real Scientific Hemp Oil tests its CBD oil three times – a process which seems to speak to the quality, purity and safety of the provider’s wares.
Owned by CV Sciences, PlusCBD Oil applies experience from the pharmaceutical industry to CBD. The company’s mission: optimize human health with the endless potential of hemp. Using state of the art production facilities and the guidance of a scientific advisory board, PlusCBD Oil is another high-quality purveyor of CBD oil that really takes CBD seriously.

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.


You’ve probably seen PureKana listed on several other “best CBD oils” lists, and it’s for good reason; in our experience (along with maybe a couple of other close competitors), they offer the best overall value in terms of potency, price, customer service, and most importantly, effectiveness. In fact, if I wasn’t continuously trying out new stuff and dedicated to reviewing every single hemp product on the market in an effort to reveal the absolute best CBD oil, I would probably use them exclusively for my lower back pain. Likewise, my partner has said several times that the 600 mg Vanilla tincture is one of his favorites for helping him sleep through the night.

All of NuLeaf’s hemp plants are grown on licensed farms in Colorado using sustainable and 100% organic farming practices. Nuleaf’s CBD oils are made using whole plant extraction. That means the final product is a full-spectrum rather than CBD isolate. Moreover, NuLeaf doesn’t include any additives like preservatives, emulsifiers, or even flavors so the final product remains in its purest form.

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.
Dr. Cohen has found that chronic conditions including autoimmune diseases and pain syndromes can be helped with a 6-mg under-the-tongue tincture (the fastest delivery system) or a 25-mg capsule taken twice a day. Dosages for topical products like lotions are especially hard to determine—there’s no clarity on how much CBD gets into the system through the skin.

Transdermal Patches – Remember those patches people put on their bodies to quit smoking? These patches allowed for a slow release of nicotine over the course of a day? Well, the same idea exists with CBD patches. This is a convenient way to get CBD into your body and endocannabinoid system over the course of a day. CLICK HERE to see our favorite patch.
Another point worth clarifying is the difference between hemp seed oil (or hemp oil) and CBD oil. There’s confusion on this point for the very good reason that both CBD oil and hemp seed oil are extracted from the industrial hemp plant. But there’s a big difference between the 2. Hemp seed oil has been pressed from hemp seed, and it’s great for a lot of things — it’s good for you, tastes great, and can be used in soap, paint — even as biodiesel fuel.
