CBD Clinicals Reviews and Rankings Methodology
What Do We Consider When Ranking Products?
CBD Clinicals (CBDC) reviews CBD brands and products to help customers make the best informed purchase decision.
We are committed to earning the trust and confidence of customers who seek to improve their health.
We apply a particular methodology to bring readers fair and objective reviews and rankings, and below are the factors that affect how we review a CBD brand.
Overall we score higher points for greater bioavailability and effectiveness of CBD in the product bought. While we consider factors such as flavor, they are weighted lower as the focus of our ratings is on the impact of CBD in the product being bought.
Each product is given an overall score out of 5 based on their scores on the following individual factors:
Our reviews give the highest ranking to CBD companies that use nanotechnology to extract CBD from hemp plants.
Nanotechnology is an extraction method that creates nano-sized particles from the extracted compound for improved absorption(1).
The second-highest ranking goes to brands that use the moonshine (ethanol-based extraction) and CO2 extraction methods. Many top brands today use these extraction methods to manufacture effective, highly potent CBD products.
CBD brands that use other extraction methods like olive oil extraction or the Rick Simpson extraction procedure get lower ratings.
CBDC also notes if a company offers products made with the purest ingredients. We award the highest rating to brands with products made from CBD and hempseed oil only.
For other products we evaluate the type of carrier oil, the presence of flavor additives and impurities such as herbicides, pesticides or fertilizers to provide a purity rating that contributes to the overall score for the product.
CBDC gives a higher rating for CBD sourced from the US and a lower rating for CBD sourced from other markets where the growing practices used are not as focused on maximizing the cannabinoid content as it is in the US.
The brands offering full-spectrum CBD products get the highest rating, followed by brands with broad-spectrum CBD products. Brands offering CBD isolate products receive the lowest rating. This is due to the impact of the entourage effect in the effectivess of the CBD product.
CBDC features CBD products at all price points. We help our readers determine the products that offer the best value for the cost by computing how much CBD they get from a given CBD per unit of volume. Those with the lowest prices of CBD per mL get the highest “CBD Value” score.
We feature CBD brands that offer products with a wide range of CBD concentrations. In our reviews, we rank the CBD product by determining the amount of CBD (in milligrams) per volume of product (in millilitres). Those with the highest amounts of CBD get the highest ratings for “CBD Strength”.
We award the highest ratings to companies with products available in four or more flavors. The brands with only natural-flavored CBD products receive the lowest rating for “Flavor Range”.
Transparency of lab results and independent third-party testing are important. Lot- and batch-specific results, preferably within the last year, need to be available.
We award the highest rating to brands with certificates of analysis (COAs) dated within the last 12 months. The COA must be from third-party labs and show test results for ingredients. We also check for the reporting of impurities in the product such as preservatives, fertilizers, pesticides, solvents, and microbes. in rating a product for transparency.
If lab results are older than 12 months, the product gets a lower transparency rating.
CBDC gives the lowest possible transparency rating to brands that do not post COAs.
Customer Service / Review
CBDC also factors in customer service when reviewing CBD brands.
We take into a number of factors in determining this as objectively as possible including:
- The number and rating of online reviews on independent customer review platforms such as Google, Facebook, Trustpilot and so on. We do not take into account any reviews on the Brand’s own website.
- The shipping policy for the product
- The product returns policy for the product.
- The experience of our team members with the brand.
All of this information is collated and a customer service score is given, which then contributes to the overall score.
