Certificates of Analysis for Supplement Ingredients: Guidelines on Their Preparation and Use

Through long-established industry practice, an ingredient supplier typically provides customers with a Certificate of Analysis (COA) with each delivered batch. The goal of this publication is to present recommendations on the content and format of such COAs including: specifications for identity and, as applicable, specifications on other characteristics such as purity, strength, composition and appropriate limits for ingredients in which there is a known or reasonable expectation that a contaminant or adulterant may be present. These guidelines are applicable to all supplement ingredients used in the manufacture of a supplement product.
