In choosing the best full-spectrum CBD oils, we looked for products that met specific criteria for safety, quality, and transparency. Each of the products on our list:
- is made by a company that provides proof of third-party testing by an ISO 17025-compliant lab
- is made with U.S.-grown hemp
- contains no more than 0.3 percent THC, according to the certificate of analysis (COA)
- passes tests for pesticides, heavy metals, and molds, according to the COA
When deciding what goes on the list, we also consider:
- the company’s certifications and manufacturing processes
- product potency
- overall ingredients
- indicators of user trust and brand reputation, such as:
- customer reviews
- whether the company has been subject to a Food and Drug Administration (FDA) warning letter
- whether the company makes any unsupported health claims
Finally, we checked reviews to get an idea of how well these products work for the customers using them.
