Course: Anatomy of a Supplement: Quality Considerations
Healthcare providers are increasingly asked to guide patients on supplement use, yet are too often left navigating a fragmented landscape of unclear standards. Many face real challenges: uncertainty around ingredient sourcing, inconsistent manufacturing practices, misleading or incomplete labeling, and a lack of transparency in product testing. These barriers add time, stress and risk, undermining clinical effectiveness, safety, and patient trust.
Led by Fullscript Product Manager Dr. Eric Viegas, ND, this course explores how supplement quality impacts clinical effectiveness and patient safety, and provides healthcare professionals with practical tools to critically assess supplements—from sourcing and manufacturing to labeling and post-market surveillance. Through real-world examples and case studies, you’ll learn how to identify quality markers, evaluate forms and dosages, and recognize potential risks.

Dr. Eric is a licensed naturopathic doctor in Ontario, Canada. He's currently a Medical Product Manager and Medical Advisor at Fullscript, focusing mainly on whole-person care, supplement quality, and practitioner education.
