CBD Isolate vs. Full-Spectrum CBD: Which One Is Right for You?

When you think of cannabis, tetrahydrocannabinol (THC) may be the first cannabinoid to come to mind. But there’s another popular cannabinoid to keep on your radar: cannabidiol (CBD).

While much of the research on CBD is new or ongoing, some evidence suggests that CBD may have certain health benefits, like pain relief.

Because of these potential benefits, CBD products of all kinds have flooded the market. It can be tough to separate the great from not-so-good products — let alone understand CBD terminology, like isolate and full-spectrum.

We’ve got you covered with this quick and easy guide to the differences between each form of CBD.

Both full-spectrum CBD and CBD isolate are extracts from the cannabis plant. But even though they come from the same plant, there are still differences.

Full-spectrum CBD products contain small amounts of other cannabinoids, like THC, as well as flavonoids and terpenes, which are beneficial compounds that provide unique scents and flavors.

CBD isolate products go through further refining, so they only contain CBD.

Isolate Full-spectrum
CBD yes yes
THC no yes
Flavonoids no yes
Terpenes no yes

The entourage effect theory suggests that taking CBD and THC together, along with terpenes, may be more effective than taking either cannabinoid alone. That’s why some people prefer to use full-spectrum CBD.

One 2011 review in the British Journal of Pharmacology found that taking a combination of terpenes and cannabinoids may help with:

  • anxiety
  • pain
  • inflammation
  • seizures
  • cancer
  • fungal infections

The same review also concludes that CBD may help lessen unwanted THC effects, like hunger, anxiety, and sedation.

Research from 2018 found that some of the terpenes and flavonoids found in cannabis may reduce inflammation and offer neuroprotective effects.

However, as with lots of other aspects of CBD, research into the entourage effect is ongoing — and not all of it agrees.

For example, a 2019 study in the journal Cannabis and Cannabinoid Research found no change in CB1 and CB2 cannabinoid receptors, a part of your endocannabinoid system, when terpenes were added to THC.

More research is needed to be able to say for sure how the entourage effect works.

Some people may want to try CBD but are iffy on THC. That’s where CBD isolate comes in, since it’s the purest form of CBD.

Though CBD isolate won’t provide any benefits from the entourage effect, some research suggests that taking CBD alone may still be beneficial.

CBD isolate may be right for you if you:

  • Want a flavorless, odorless product. Though some CBD isolate products have added flavoring, unflavored products should be pretty taste-free.
  • Want to avoid THC altogether.
  • Want to take large doses of CBD.
  • Have to undergo drug testing. Full-spectrum CBD may be more likely to show up on a drug test. However, there may be a slight possibility that isolate products will show up, too. Even “THC-free” CBD products may contain trace amounts of THC.

Full-spectrum CBD may be the right choice if you want:

  • The benefits of the entourage effect. Since the amount of THC will be less than 0.3 percent, you shouldn’t experience any of THC’s psychoactive effects.
  • An earthy flavor profile. You can find flavored full-spectrum products, but unflavored varieties will have a slightly earthy taste.
  • A less refined product. CBD isolate has to go through more refining than full-spectrum THC.

Some CBD companies make misleading claims about their products — some even mislabel them. And since the FDA doesn’t regulate CBD products the same way it regulates dietary supplements or drugs, that means it’s super important to do careful research.

Look out for the following when shopping for CBD products:

Test results

Look for products that include an up-to-date COA from a third-party lab. Some companies will ship the COA with the product, while others may post it online. In some cases, you may have to request it by email.

Here’s what to check for when you review the COA:

  • Contaminants. Check that the product doesn’t contain pesticides, mold, or heavy metals.
  • Cannabinoid profile. If you’re interested in purchasing a CBD isolate product, for instance, verify that the product is free of THC.
  • Potency. Check that the amount of CBD listed on the COA matches what’s listed on the label.


Be sure the product you’re buying actually contains CBD. If the ingredients list only says hempseed oil or Cannabis sativa oil, it doesn’t contain CBD.

CBD source

Opt for products made from organic, U.S.-grown hemp. U.S.-grown hemp is subject to regulation, so it can’t contain more than 0.3 percent THC by law.

CBD type

It’s up to you which kind of CBD you choose, but if you prefer to avoid THC, choose a CBD isolate product. If you’d like to have other cannabis compounds, choose a full-spectrum product.

Product type

There are all sorts of CBD products out there, from topicals to gummies.

Topical CBD products help target specific pain areas. Oils and gummies are more useful for whole-body relief.
