NOW has partnered with botanical genomics company LeafWorks to integrate next-generation DNA sequencing into its botanical identity testing programme.
The collaboration brings LeafWorks' purpose-built DNA Analysis Platform into NOW's quality workflow, enabling high-throughput genomic interpretation through a curated reference database and validated analytical systems designed for complex botanical formulations.
As part of the partnership, NOW has established a next-generation sequencing lab at its facility in Sparks, Nevada, to support testing across its portfolio. The company generates sequencing output in-house and applies it to LeafWorks' platform for species-level validation at scale.
"We are always looking for ways to strengthen our quality systems and ensure the integrity of our products," said Maria Mendres, Microbiology Manager at NOW.
Incorporating next-generation DNA sequencing for genomic-level ID adds another valuable tool to our testing programme, enhancing our ability to verify botanical identity.
"The number of species we can test for simultaneously is unique to DNA and LeafWorks' platform, making it a good fit for NOW with over 2000 ingredients."
The model allows companies to access advanced genomic analysis without building a bioinformatics infrastructure internally.
NOW shares digital sequence data with LeafWorks for analysis and receives detailed Certificates of Analysis supporting identity verification across its product range.
Kerin Law, co-founder and Chief Scientific Officer of LeafWorks, said the approach removes a longstanding barrier to adopting DNA-based testing.
Companies can generate sequencing data in-house and plug directly into our analysis platform without needing to build complex bioinformatics systems themselves.
"This unique combination of accessibility and rigour is an entirely new model of testing to move the industry forward."
DNA testing has been used in natural products for more than a decade, but earlier methods, including universal DNA barcoding, relied on uncurated databases and markers that often struggled to deliver consistent species-level identification in processed products.
LeafWorks' third-generation platform uses species-targeted genomic methods, authenticated reference materials and purpose-built analytical systems designed specifically for commercial botanicals, aiming to improve specificity and reliability across multi-ingredient products.
Because sequence data is digital, NOW's workflow connects directly to LeafWorks' platform, supporting consistent, scalable interpretation across high sample volumes.
The companies say the partnership reflects a broader industry shift toward precise, simultaneous multi-species analysis as a foundation for data-driven botanical identity verification.
