For the first time, dietary supplement ingredient suppliers can use an on-label, NSF DNA Authenticated mark to verify the identity and purity of raw ingredients. NSF International recently launched its new, independent testing protocol and verification program for raw botanical ingredients used in the dietary supplement industry.

In addition to DNA authentication of the target species, the testing program also screens for contamination, including common adulterants, toxic adulterants, allergens and fillers. DNA Authenticated verification requires next-generation sequencing (NGS) DNA testing of every lot or batch that bears the mark. Suppliers can provide DNA Authenticated certificates and use the verification mark on shipments of verified ingredients.

“With complex global supply chains and fraudulent ingredients popping up in unexpected places, DNA authentication of raw ingredients is a prudent step for supplement manufacturers who are concerned about the quality and purity of products,” said Jesse Miller, PhD, director of applied research at NSF International. “With the new DNA Authenticated mark, manufacturers, suppliers and ultimately, consumers can be absolutely sure the ingredients they choose have been accurately identified.”

NSF International maintains a database of validated DNA reference sequences for all relevant botanical ingredient and adulterant species of plants, fungi and probiotic bacteria. Many of NSF International’s DNA reference sequences have been obtained as herbarium specimens through partnerships with top institutions such as Harvard University and the University of California, Berkeley.

Miller was recently appointed to lead NSF AuthenTechnologies, the team that is testing and certifying ingredients to the DNA Authenticated protocol. Under Miller’s leadership, NSF AuthenTechnologies is expanding the range of services it provides and re-engineering many of its testing, customer service and reporting processes. “Alignment with our scientific processes and innovation is essential, as are customer service and convenience. We’re working to make it easy for customers to use NSF AuthenTechnologies services,” Miller said.
