CBD is a cannabinoid found in hemp and marijuana plants. Though it is present in both plants, hemp contains such low amounts of THC, and such high amounts of CBD, that it is ideal for CBD extraction. As the name suggests, CBD isolate is the compound in its purest form. At room temperature, it is a white powder with no other compounds. Full-spectrum CBD oil contains additional cannabinoids, like CBN, CBL, and CBCVA. It also has aromatic compounds called terpenes. Pinene and Limonene give full-spectrum oils a grassy, earthy scent.
While full-spectrum products have been shown to be effective, they may not be the ideal choice for everyone. CBD products contain extremely minimal amounts of THC, the psychoactive compound in cannabis products. Though the THC in CBD supplements should not exceed 0.3% of the total product volume, people who must be drug tested for work may choose to avoid full-spectrum products, just to stay on the safe side.
Full-spectrum oils can also have unpleasant flavors. As discussed earlier, hemp contains other cannabinoids and aromatic terpenes that contribute additional tastes. Some people can tolerate the full hemp flavor; others, however, cannot stomach it. This problem is particularly noticeable in products that are intended to be held in the mouth rather than quickly swallowed, like CBD tinctures.
An isolate boasts the benefits of CBD without the slight risk of triggering positive drug test results. Isolates do not have extra flavors that can be undesirable; in fact, CBD isolate drops can be added to popular, pleasant flavors, like juice, oatmeal, or coffee, that would not mix well with full-spectrum hemp oil. CBD isolates have very high concentrations of CBD, upwards of 99%. For people who want CBD exclusively and care little about consuming the other cannabinoids or terpenes, isolates may be preferable.
