What is the most effective way to verify that a purchased wild lettuce supplement contains no unexpected or adulterated ingredients?
Answer
Reviewing a third-party Certificate of Analysis
A Certificate of Analysis (COA) is a document issued by an independent laboratory that validates the contents of a product. Obtaining a COA from a reputable manufacturer ensures the product has been tested for purity and confirms that no undeclared substances or contaminants are present, which is the best method to avoid accidental positive drug tests from impure supplements.
