Dietary supplement companies are facing a new wave of consumer class actions challenging product labeling and marketing. Plaintiffs' firms are increasingly relying on third-party laboratory testing and consumer protection statutes (not Food and Drug Administration (FDA) enforcement) to challenge claims regarding purity, contaminants, ingredient content, and product quality. Even companies with strong quality systems are finding themselves defending costly litigation based on alleged discrepancies between marketing claims and independent testing.
Companies should reassess the substantiation supporting their advertising and labeling, evaluate quality control and supplier verification programs, and prepare for increased scrutiny of contaminant and purity claims. Early legal review can significantly reduce litigation risk while preserving consumer trust.
A Rapidly Expanding Litigation Trend
Consumer class actions against dietary supplement manufacturers continue to evolve beyond traditional health and efficacy claims. Plaintiffs are now targeting a broad range of product representations, including:
- "Clean," "pure," or "natural" marketing claims;
- Claims regarding heavy metals, per- and polyfluoroalkyl substances (PFAS), phthalates, pesticides, or other alleged contaminants;
- Ingredient identity, potency, and dosage representations;
- Labeling regarding protein, calories, carbohydrates, and other nutritional content;
- Manufacturing quality and testing representations; and
- Premium pricing based on allegedly superior purity or quality.
Unlike FDA enforcement actions, these lawsuits frequently arise after advocacy groups or private laboratories publish testing results that receive significant media attention. Plaintiffs then allege that consumers paid a premium for products they would not have purchased, or would have paid less for, had the alleged contamination or labeling discrepancies been disclosed. Industry observers have noted that contaminant-based consumer litigation has become an increasingly common strategy in recent years.
What's Driving the Increase?
Several factors are fueling this litigation trend.
Third-party testing is becoming more sophisticated. Consumer advocacy organizations and private laboratories are using increasingly sensitive analytical methods to detect trace levels of heavy metals, PFAS, phthalates, and other substances that may occur naturally or through manufacturing, packaging, or supply chains. Even trace findings, regardless of regulatory significance, can become the basis for false advertising claims.
The increasing use of third-party laboratory testing by plaintiffs' firms changes the economics of litigation. Companies are no longer defending allegations based solely on consumer perceptions or marketing language; they are increasingly responding to claims supported by scientific testing that may require competing experts, additional product testing, and extensive discovery to resolve.
Regulators continue to scrutinize advertising substantiation. The Federal Trade Commission (FTC) has intensified enforcement against dietary supplement marketers making unsubstantiated health claims and continues to emphasize that objective health-related advertising claims require competent and reliable scientific evidence.
Why This Matters for Supplement Companies
These lawsuits can create significant business disruption regardless of their ultimate merits.
Companies frequently incur substantial litigation costs, reputational harm, retailer concerns, insurance issues, product reformulation expenses and increased scrutiny from regulators and investors. Allegations involving contaminants or product purity often generate negative publicity long before any court determines whether the claims are scientifically or legally supported.
Businesses should also recognize that plaintiffs increasingly target not only manufacturers, but also private-label brands, retailers, distributors, contract manufacturers, and companies making premium quality or purity representations.
Practical Steps to Reduce Risk
Companies should consider taking the following proactive measures:
- Review all marketing and labeling claims for appropriate substantiation.
- Reevaluate "clean," "pure," "natural," "contaminant-free," and similar marketing language.
- Assess supplier qualifications, ingredient specifications, and contractual quality obligations.
- Review contaminant testing protocols and documentation, including how results are interpreted and communicated.
- Evaluate whether advertising accurately reflects product testing and manufacturing practices.
- Develop litigation response protocols before receiving a demand letter or complaint.
Although FDA regulations prohibit adulterated and misbranded dietary supplements, consumer class actions increasingly test compliance under broader state consumer protection statutes rather than relying solely on federal regulatory standards.
Next Steps
Given the continued increase in false advertising and contaminant-based litigation, dietary supplement companies should evaluate their marketing claims, testing programs, and quality documentation before becoming the next litigation target.
If your company markets dietary supplements or other health and wellness products, you should seek outside counsel to conduct a privileged litigation risk assessment of your product claims, labeling, testing protocols, and supplier documentation to identify potential exposure and recommend practical strategies to reduce risk before claims arise.
