Herbalife Scientists to Showcase Advancements in Ingredient Safety and Nutritional Quality at 2024 AOAC INTERNATIONAL Annual Meeting

Herbalife, a premier health and wellness company, community and platform, announced today that it will participate at the 2024 AOAC INTERNATIONAL (Association of Official Analytical Collaboration) Annual Meeting & Exposition in Baltimore, Maryland, from August 23-28. The company will showcase innovative methods that help ensure ingredient identification and product quality for public health. This year marks Herbalife’s eighth year participating in the conference.

“As a global leader in nutrition for more than four decades, Herbalife prioritizes public safety and innovation within the rapidly evolving dietary supplements industry,” said Gary Swanson, senior vice president, Global Quality Control, Herbalife. “We, along with other industry leaders, are able to maintain product reliability and quality for consumers by sharing best practices and leveraging advanced technologies.”

Herbalife’s science-backed approach to product development is driven by a robust team of scientists and Ph.D.s that help the company meet the most demanding safety and quality standards in the industry.

Adam Faller, Ph.D., Analytical Scientist II, Corporate Center of Excellence Lab, Herbalife, will give a presentation titled, “Using Quantitative Polymerase Chain Reaction (qPCR) for Uniformity Analysis of Finished Botanical Blend Products.” The presentation will focus on the use of quantitative genomic analysis as a novel process control tool for popular "super green" vegan dietary supplements, which are designed to boost overall wellness through a blend of various green vegetables, algae, grasses, and other plant-based ingredients. Dr. Faller’s presentation will be part of the “Mo’ Dietary Supplements, Mo’ Problems?”: Overcoming Analytical Challenges with Modern Technologies” symposium.

Herbalife will also present seven scientific posters addressing key challenges in dietary supplement safety, efficacy and quality, including:

• “Liquid Nitrogen-Free Sample Preparation for Active Ingredients Assay in Oil- and Water-Soluble Vitamins with Minerals Chewable Gels” – Wei Liu, Analytical Scientist I, and Weiti Wang, Chemist II, Corporate Center of Excellence Lab, Herbalife. This work introduces a safe, cost-effective method for testing micronutrients in chewable supplements, ensuring that chewable products deliver nutrients as labeled.

“A Single-Laboratory Validation of the Test Method of the Determination of EPA, DHA in Chewable Products by GC-FID”– Wei Liu, Analytical Scientist I, Corporate Center of Excellence Lab, Herbalife.
