In the natural products sector, nothing matters more than trust. Brands promise authenticity, regulators expect compliance and consumers assume that what’s on the label is what’s in the bottle.
When adulteration creeps into the ingredient supply chain—whether by accident or intent—that trust begins to erode.
At LeafWorks, we’ve seen how easily this can happen. Certain species of botanicals may have lookalikes or ingredients that smell similar, but aren’t actually the raw material a product manufacturer expects. Fine powders and extracts make it impossible to tell the difference with the naked eye. And in global trade, the risks only multiply. That’s why adulteration prevention in natural products is not simply a matter of compliance. It’s a matter of protecting consumer safety and brand reputation.
Why Adulteration Happens
Adulteration can stem from many causes: Economic motivations may lead to the substitution of cheaper materials; complex supply chains raise the potential for mistaken identity when similar species are traded globally.
At the formulation level, there are added processing challenges. Once botanicals are powdered, extracted or blended, traditional ID methods may struggle to differentiate these ingredients from one another.
The results can be damaging, including regulatory penalties and costly recalls to harm for consumers who depend on natural products for their health and wellness.
The Limits of Traditional Methods
Traditional tools for identification, such as microscopy, macroscopy and chemistry-based assays, all provide useful information, but each has its limitations.
-
Microscopy/macroscopy: Once material is ground or highly processed, morphological features disappear.
-
Chemistry assays: Many species share overlapping compound profiles, making it difficult to know which plant or fungal species a certain compound came from. Environmental conditions can also affect metabolite levels creating unexpected profiles.
This is where DNA analysis offers an orthogonal or alternative method—one that cuts through ambiguity. By targeting stable, species-specific regions of the genome, LeafWorks’ DNA testing provides definitive answers, even in blends or processed products.
Building on Industry Initiatives
Brand leaders for natural products have long recognized the need to tackle adulteration proactively. Truth-seeking parties across the herbal and dietary supplement industry raised concerns years ago about confirmed cases of adulteration in raw materials, extracts and essential oils.
To address this, three nonprofit organizations, the American Botanical Council (ABC), the American Herbal Pharmacopeia (AHP) and the University of Mississippi’s National Center for Natural Products Research (NCNPR) formed the Botanical Adulterants Prevention Program. Since its inception, BAPP has helped to raise awareness of known risks and developed solutions for preventing adulteration in dietary supplements, botanical products, conventional foods, OTC drugs and cosmetics.
LeafWorks complements those efforts with two types of DNA testing:
-
LeafWorks® Botanical DNA ID Tests answer the question, “Is this the ingredient I think it is?”—confirming that species identity matches label expectations for any of the top 75 herbs and fungi.
-
LeafWorks® Adulteration DNA ID Testing goes further, screening for common adulterants such as peanut, rice and wheat, as well as common substitutions or contaminants.
Together, these services give brands the ability to verify authenticity and prevent adulteration across raw materials, blends, and finished products.
While BAPP offers guidance for the industry, LeafWorks provides lab-verified data that identifies adulterants with scientific precision—giving companies a defensible layer of protection on top of industry best practices.
LeafWorks’ Scientific Approach
The LeafWorks team built our testing processes with the objective to deliver results that are both scientifically rigorous and commercially reliable. Here’s how we do it:
-
Species-specific markers: Unlike universal genetic markers that can generate false positives or negatives, we target genome regions unique to each species.
-
Authenticated reference materials: Every assay is validated against LeafWorks’ extensive DNA library, built from thousands of expert-authenticated Botanical Reference and Certified Reference Materials.
-
qPCR and sequencing: These methods provide flexibility and sensitive insights, particularly in complex blends.
-
Regulatory alignment: Tests are validated and meet requirements under 21 CFR Part 111, ensuring defensible results for audits and compliance.
This combination of precision, reproducibility and validation makes our assays fit for both scientific scrutiny and regulatory use.
Why It Matters
Adulteration is more common than many realize. With industry guidance like BAPP and labs that conduct testing for verification, companies can safeguard their products on multiple levels.
For sourcing managers, that means confidence in global purchasing. For QA/QC teams, it means stronger protection against recalls. For consumers, it means peace of mind that natural products are safe, authentic, and effective.
At its core, adulteration prevention is about building trust through transparency. By combining industry-wide awareness with cutting-edge genomic science, LeafWorks helps natural products companies take a proactive stance in protecting their supply chains.
Because in a marketplace where authenticity is everything, scientific rigor is the strongest safeguard.
