You may be selling or developing countless different supplements and nutraceuticals so it is essential to find a lab that can perform a wide range of tests. Twin Arbor Labs is an ISO 17025 accredited lab with services that cover a wide range of analytical and microbiological techniques ranging from chromatographic techniques used for label specification verification of individual ingredients to plating and molecular techniques used to confirm probiotic specifications. For ingredients, such as botanical extracts, that cannot be directly measured, we can also perform batch sheet verification by inputs or direct measurements of chemical markers found in different botanical substances.

Supplement Adulterant Testing

In addition to an ingredient verification, Amazon may be asking you to furnish a Certificate of Analysis (COA) indicating the absence of certain adulterants. Supplements intended for sexual enhancement, weight loss or weight management, and those intended for sports nutrition and body building must have a COA that indicates the absence of certain adulterants. Twin Arbor Labs offers adulterant testing specifically designed to screen different classes of supplements or nutraceuticals with the high degree of accuracy and sensitivity required by Amazon.
