Ensuring the safety, quality, and authenticity of dietary supplements has become increasingly complex in today’s global marketplace. Misbranding, mislabeling, and adulteration continue to pose serious risks, leading to health hazards, regulatory enforcement actions, and loss of consumer trust. Undeclared pharmaceutical ingredients, incorrect dosage labeling, and contamination incidents have resulted in recalls and significant reputational damage.

To protect consumers and brands alike, robust quality systems, third-party certifications, and traceability measures are essential. 

This webinar will first highlight key integrity challenges facing the dietary supplement industry, from misleading claims to adulteration concerns, before moving into advanced analytical solutions that address them. Special emphasis will be placed on targeted and non-targeted LC-MS workflows, which are increasingly vital for detecting pharmaceutical adulterants, contaminants, residues, or packaging migrants. Attendees will learn how suspect screening and non-target analysis enable early detection of risks, authenticity verification through fingerprinting, and data-driven decision making to monitor or improve product quality. 

Real-world examples will illustrate how advanced LC-MS workflows safeguard compliance, support efficient recall management, and strengthen consumer trust. Join us to explore how proactive testing strategies can protect consumers, reduce regulatory risks, and build lasting confidence in dietary supplement products.
