About the product

Pure Spectrum claims this is a broad-spectrum hemp extract, which suggests that it contains CBD, other cannabinoids, and zero THC.

Our lab tests found that the Hemp Oil Tincture contained CBD and CBDV. This product is not a broad-spectrum hemp extract. We describe this product as a “CBD oil.”

We found that Pure Spectrum contained 6.8% more cannabinoids than suggested by their label.

Pure Spectrum recommends “dispensing the tincture under the tongue and holding it there for at least 30-90 seconds.”

About the company

Pure Spectrum is a small Colorado-based company with retail stores in Evergreen, CO, and La Jolla, CA.

The good:

The bad:

  • It’s a small team. Pure Spectrum has nine people on their team, according to their “about us” page. However, they source from a well-established organic farm, and it’s nice to see the names and faces behind the company on their website.
  • The product we tested claimed that it was “broad spectrum,” but only contained CBD with small amounts of CBDV. Their Hemp Oil Tincture should be labeled as a CBD oil instead of a broad-spectrum oil. Pure Spectrum also provided us with a lab test that showed only CBD in this product, which further suggests it should not be labeled a broad-spectrum product.

The internet:

  • An extensive internet search for Pure Spectrum found no reports of inconsistency, toxins, pesticides, metals, fake products, or unethical business practices.

Other sizes available

Pure Spectrum also offers the Hemp Oil Tincture in potencies of 1200 mg ($124.88) and 2500 mg ($228.88). However, these higher potency versions are not the same formula as the 500 mg ($54.88) bottle that we tested and we can’t provide information on their cannabinoid levels, accuracy, or value.
