What is the benefit of CBD isolate?


Have you heard the term CBD isolate and wondered what it is and what are its benefits?   CBD isolate is considered the purest form of CBD.  All of the other compounds and impurities have been removed from the cannabis plant during the extraction process so that the end result is a crystalline powder that is purely colorless and odorless containing 99 percent CBD. CBD isolate generally is extracted from the hemp plant due to its low to non-existent THC content, less than 0.3 percent.

CBD isolate contains no THC

In contrast to CBD isolate, full spectrum CBD contains all the naturally-occurring compounds found in the cannabis plan, including terpenes, which are aromatic plant; flavonoids, a diverse group of plant chemicals thought to fight off free radicals, essential oils and cannabinol (CBN). However, full-spectrum CBD also contains the more than 100 additional cannabinoids, notably Tetrahydrocannabinol THC, which is marijuana’s main active ingredient and is psychoactive. 

This means that full-spectrum CBD may have trace amounts of THC, posing a risk for anyone facing a drug test for a new job or working for a company that routinely tests for drugs.  While employers aren’t looking for CBD, workers fail company drug testing because of THC, which exist in low amounts in some CBD products and remain in the body for weeks.[1] Furthermore, some states have strict THC laws.  States that haven't legalized medical marijuana allow limited use of cannabis oils if they contain a low level of THC and a high-level CBD.[2]

How CBD isolate is made

Extracting CBD isolate from the hemp plant is complex. Once the CBD is extracted further processing removes additional cannabinoids, terpenes, and flavonoids. The oil then goes through a “winterization” process. This involves soaking the CBD extract in alcohol and freezing (winterizing) it in order to separate the pure CBD from any residual substances that remain in the oil.

After it has been winterized, the CBD is put through several rounds of rotary evaporation to make extra sure that all residual material has been extracted. The remaining oil is heated and converted into pure, crystalized CBD before it is processed into a crystalline powder form. [3]

Terpene-Infused Isolates Emerge

Some manufacturers, including Lab+ Blends, now are infusing the CBD isolate with combinations of terpenes.  This new method enhances the benefits of the CBD and allows for customization of the product to treat specific conditions.  For example, certain terpenes are good for relieving for pain while others help with stress. Furthermore, some CBD has a very small percentage of terpenes in it.  With a customized blend, you can have a higher percentage of terpenes than you’d find in nature.

Ways to consume CBD isolate

When it comes to consuming CBD isolate, there is an array of available consumption methods. CBD isolate products include oils, topicals, tinctures, capsules, edibles, and more. Based on need, different absorption methods will be most appropriate.

Ingestion and Sublingual Application: Whether in capsules, food or liquid, CBD that is swallowed is absorbed through the digestive tract. With capsules, the effective dose already has been established. CBD can also be absorbed directly into the bloodstream bypassing the digestive system by holding liquid from a spray or tincture (a liquid dosed by a dropper) under the tongue (sublingual) for 60 to 120 seconds. The effects may be felt within 15 to 45 minutes.[4]

On the skin: Topical products, including creams, lotion, balms and gels are applied to the skin over the area where there is pain. When CBD is applied topically, it never reaches the bloodstream but can be absorbed through the skin’s surface to interact with nearby cannabinoid receptors.[5] Since topical CBD use is localized, there is no need to dose too much. Assume a little cream goes a long way and start with a small amount on the problem area. After an hour or so, try reapplying. Any of the topicals that have Camphor, Lidocaine or Menthol can be applied up to 3-4 times a day.

Inhalation: CBD can be inhaled via a vaporizing, or vape pen. Inhaled CBD tends to enter the bloodstream faster than other forms. However, controlling dosages can be difficult because how much CBD is absorbed depends on how long and hard the inhalation is.[6]

CBD will affect everyone differently.  Your weight, diet, metabolism, other medications, genetics, and medical conditions, as well as the formulation and quality of the CBD product itself all can influence the amount of therapeutic value that CBD will offer.  Also, depending on the therapeutic needs, different CBD products may prove more beneficial than others. [7] A good idea is to track the effects of a product for a week or so to see the effect of the product.
