What’s the Difference Between Full Spectrum, Broad Spectrum & Pure

CBD products are increasingly popular across the UK — but with so many different types available, it can be difficult to know which one is best for you.

One of the most common questions we’re asked is:

“What’s the difference between Full Spectrum, Broad Spectrum, and Pure CBD oils?”

Let’s break it down clearly.

Full Spectrum CBD Oil

Only Green Full Spectrum CBD Oil – 3000mg

Our best-selling full spectrum oil with natural cannabinoids for maximum wellness support.

View Product

Full Spectrum CBD contains all the naturally occurring cannabinoids found in the cannabis plant — including trace amounts of THC and THCV (less than 0.2%).

Although this amount is too small to produce any psychoactive effect, the presence of these compounds contributes to what’s known as the entourage effect.

The entourage effect refers to the idea that cannabinoids such as CBD, CBG, CBC, and CBN are more effective when a small amount of THC and THCV is also present.

This natural synergy enhances the overall benefits, which is why we include trace levels of THC and THCV in our Full Spectrum oils.

Broad Spectrum CBD Oil

Only Green 30% Broad Spectrum Oil

A potent broad spectrum CBD oil (£50) containing CBD, CBC, CBG, and CBN — completely THC-free for those seeking a powerful, clean formulation.

Broad Spectrum CBD also includes a wide range of cannabinoids — excluding THC and THCV.

While it’s extremely unlikely that Full Spectrum CBD would result in a positive drug test, some people prefer to eliminate the risk entirely. Broad Spectrum oils are ideal for customers who want to experience the benefits of multiple cannabinoids, without any THC in their system.

Pure CBD Oil (Isolate)

Only Green Pure CBD Oil

A THC-free CBD oil available in 10% (1,000 mg) or 20% (2,000 mg) strengths—certified organic and lab-tested for purity. Completely free of additives.

Pure CBD oil, also known as CBD isolate, contains only CBD — with no other cannabinoids, terpenes, or plant compounds.

This type of CBD is well suited to individuals who:

Require a precise, consistent dosage
Are sensitive to other cannabinoids or terpenes
Prefer to completely avoid any additional compounds found in the cannabis plant
