Overall CBDC Brand Rating for Pure Spectrum: 8/10

Pure Spectrum specializes in three CBD product lines: the original Pure Spectrum CBD, Black Label, and EndoPets. All three product line ups are formulated to target specific lifestyles and concerns. 

The company promises that its CBD products are made with phytocannabinoid-rich, whole-plant extracts without tetrahydrocannabinol (THC). However, the brand’s extraction method used in obtaining its CBD extract was not specified.

The brand’s certificates of analysis, dated December 2020, shows the amount of CBD per serving size. Unfortunately, the lab results for contaminants are not available.

Pure SpectrumCBD offers a wide range of products that include CBD tinctures, CBD salve, and CBD bath soaks. They also offer CBD tinctures and CBD chewables for cats and dogs. 

However, it would be best if the company also provided ample information on the usage and dosage, as they are not mentioned on their website.

Still, Pure Spectrum gives back to veterans and first responders by offering them discounted prices as part of the brand’s Heroes Program. The company also ships internationally.

Optimizing Wellness

Pure Spectrum asserts its commitment to deliver high-quality CBD oil formulated to promote optimal health and assist in body recovery. 

This CBD brand aims to cater to promote health care for athletes and people with active lifestyles. 

A study has shown that CBD may have the ability to modulate the body’s inflammatory processes(6). Since persistent inflammation may defer functional recovery and prolong muscle pain, it is crucial to note CBD’s possible stimulation of anti-inflammatory cytokines. 

The study also highlighted that a high dose of CBD was associated with muscle strength improvement and coordination(7).

Source of Hemp

The brand claims that it uses organic hemp extract sourced from its US Department of Agriculture (USDA)-approved partner farms and cultivars in Colorado. 

Among the brand’s line of products, the 500mg regular strength Pure Spectrum Cannabidiol oil is the most popular. 

Types Sold

Pure Spectrum focuses on broad-spectrum CBD and CBD isolates. 

The brand does not offer full-spectrum CBD, which has all the phytocannabinoids, including tetrahydrocannabinol (THC), and terpenes found in hemp plants. 

Full-spectrum cannabis products are believed to produce the most therapeutic benefits(8).  The terpene profiles’ positive contribution to the effects of cannabinoid creates a synergy called the entourage effect(9)

Research shows the binding of these phytocannabinoids to the endogenous receptors found in the endocannabinoid system (ECS) of mammals(10). The ECS affects the functions of the nervous, gastrointestinal, and endocrine systems(11).

CBD-rich full-spectrum extracts derived from hemp with low THC content are considered federally legal in the United States(12). However, full-spectrum CBD extracts’ safety have yet to be proven by further studies and research.
