SIDI Working Group releases CoA guideline for dietary supplement makers

WASHINGTON The Joint Standardized Information on Dietary Supplement Ingredients Working Group — a coalition of the dietary supplement industry’s trade associations — on Thursday announced the release of the new Certificate of Analysis guideline, the latest in a series of voluntary guidelines for the supplement industry, developed to assist finished product manufacturers with the complex process of qualifying their ingredient suppliers.

The voluntary CoA guideline outlines the type and scope of information that should appear on a CoA provided by an ingredient supplier to its finished product manufacturer for a component or ingredient used in a dietary supplement.

“A requirement of the supplier qualification process involves verifying the information provided in an ingredient CoA, and manufacturers of dietary supplements rely on supplier CoAs to ensure finished products are GMP-compliant,” stated Andrew Shao, a spokesperson for the SIDI Working Group and SVP scientific & regulatory affairs at the Council for Responsible Nutrition. “It’s essential for ingredient suppliers to have a form that can be consistently used, containing the appropriate information in a clear and concise format. … By standardizing the information on CoAs, this voluntary guideline will benefit both ingredient suppliers and dietary supplement manufacturers.”

The voluntary CoA guideline, along with sample CoA templates for botanical and non-botanical ingredients, is available on the five trade associations’ websites, along with the original SIDI protocol materials.

The SIDI Working Group is a cooperative effort run by the dietary supplement industry trade associations including the American Herbal Products Association, the Consumer Healthcare Products Association, CRN, the Natural Products Association and the United Natural Products Alliance.
