Ensure the integrity and purity of dietary supplements and natural health products with advanced NMR-based analytics. This application note demonstrates how NMR spectroscopy enables accurate molecular identification, structural authentication, and quantitative purity assessment—without reliance on reference standards. Learn how NMR differentiates isomers, detects excipients, and verifies species authenticity, all in a single, eco-friendly workflow. Explore case studies on NMNH, Urolithin-A diacetate, and trans-resveratrol to see how NMR delivers robust, reproducible results for quality assurance and regulatory compliance.
