CBD isolate is what we call pure CBD. That means that solely CBD has been extracted from the plant and no other plant constituents are in the product. The benefit of an isolate is that it contains absolutely zero THC, which is a great option for anyone concerned with passing a drug test. On the other hand, isolate oils may need more overall CBD content to be considered as effective as the whole plant medicine within full and broad spectrum CBD oils.
But it's not just the CBD concentration that makes a tincture strong; there are other factors that you'll want to keep in mind as well. For instance, the type of hemp extract used to create the product (i.e. full spectrum, broad spectrum, or isolate) may also play a factor in its overall strength.
This is the highest-concentration CBD oil available from Charlotte's Web, offering a full 60 milligrams of CBD per serving.

It also comes in three delicious flavors, including Mint Chocolate, Lemon Twist, and Orange Blossom.
How Do I Determine CBD Oil Strength?
If you're an experienced CBD consumer, you may be comfortable experimenting with high-strength CBD oils. Just keep in mind that CBD may affect certain medications, such as the blood thinner coumadin, so you'll want to be extra cautious of your CBD dosage if you are on prescription medications. If this is the case, check with your physician before incorporating a strong CBD oil into your daily regimen.
Let's start with full spectrum CBD oil. This is made with whole plant extract with nothing removed or added, so it's totally natural. The least manipulated of the CBD oil options, full spectrum maintains a full range of cannabinoids and terpenes, resulting in the desirable entourage effect, in which all of the compounds work together to provide the greatest benefits a CBD oil can provide.

Lab Testing & Transparency: Lab testing is important in the CBD space. All reputable CBD companies publish their lab results upfront, making it easy for consumers to separate good and bad CBD oil products. We preferred CBD oils backed by third-party lab tests performed by reputable labs. The best CBD oils use ISO 17025-compliant labs for testing. The worst CBD companies use in-house labs while refusing to disclose certificates of analysis (CoAs).

A: Some use the terms CBD oil and hemp oil interchangeably. However, the two things are different. CBD oil is made from the flower, bud, stems, and leaves of the cannabis plant. Hemp oil or hempseed oil is made from the hemp seeds of the cannabis plant and contains no THC.
In this 2018 study, for example, researchers gave 2mg or 8mg per kg of CBD oil to dogs with osteoarthritis over a four-week period. Researchers found that doses as low as 2mg per kg of CBD oil per day, taken twice daily, can help increase comfort and activity in dogs with osteoarthritis.
