Learn More About the Supplement OWL

CRN Supplement Owl

The Supplement OWL® (Online Wellness Library)—the dietary supplement product registry—is an industry-wide, self-regulatory initiative that is helping create a rich and more complete picture of the marketplace for consumers, businesses, and regulators. The Supplement OWL serves as a resource for these audiences to identify products, their ingredients and the companies who market them, and permit registry users to examine and evaluate labels and other product information.

The Supplement OWL® is a self-regulatory initiative of the dietary supplement industry, spearheaded by the Council for Responsible Nutrition (CRN).

The Supplement OWL went live in April of 2017, with a benchmark 10,000 labels in April of 2018, and is consistently growing as more companies realize the value of participation in this voluntary effort.

The Supplement OWL Advisory Board, convened in October 2017, is composed of stakeholders from all corners of the supplement industry and provides a forum to discuss the OWL’s progress.

The Supplement OWL® entries include an image of the product, a complete product label, and various fields of information about the product such as: ingredients; dosage form; product claims from the label; and contact information. These records are available online for viewing by anyone using the Supplement OWL. Companies submitting their labels are also required to provide manufacturing and packaging facility contact information, accessible only to FDA, the regulatory body that oversees dietary supplement labeling. There is no cost to participate in the Supplement OWL.

Anyone with web access can use the Supplement OWL®.

Created by the dietary supplement industry as a self-regulatory tool to provide a more complete understanding of the marketplace and the range of products and ingredients to FDA, the Supplement OWL is also accessible to dietary supplements users seeking full transparency of the companies from which they purchase. Retailers and other business stakeholders are also frequent users of the OWL.
