To sell dietary supplements on Amazon US, sellers must comply with specific regulations to ensure product safety and build consumer trust. This includes meeting manufacturing standards like GMP and undergoing testing by approved third-party verification organizations (TICs). All requirements must be confirmed by one of three authorized TICs, with detailed policies available on Amazon Seller Central. Products in categories such as sports nutrition, sexual wellness, weight management, or joint health must also be tested for undeclared pharmaceutical ingredients, following NSF/ANSI 173-2024 guidelines. Sellers are free to choose any ISO/IEC 17025-accredited laboratory to meet these requirements. Our experienced team specializes in detecting adulterants in dietary supplements within these categories, providing validated testing results and certificates of analysis. We are dedicated to guiding companies through Amazon’s certification process and ensuring compliance—just reach out with any questions.
