Nutrition Expert Witnesses

Food, beverage, and dietary supplement manufacturers face litigation whenever a product’s health or nutritional claims are challenged as unsupported, misleading, or inconsistent with current nutritional science. These disputes commonly surface as false advertising and consumer protection class actions against manufacturers, regulatory enforcement actions concerning label compliance, and product liability claims alleging that a supplement or food ingredient contributed to a health condition. Because nutritional science evolves and often produces competing findings, the central issue is typically whether the available epidemiological and clinical evidence actually supports the causal link a plaintiff or regulator alleges. Resolving that question requires distinguishing correlation from causation across studies that vary widely in design and rigor.

A nutrition expert reviews the underlying clinical and epidemiological literature to determine whether it substantiates or undermines a product’s marketing claims, and evaluates whether labeling and health statements comply with FDA and related regulatory standards. That analysis frequently informs causation, since the expert can assess whether a claimed adverse health outcome is more plausibly explained by diet-wide, genetic, or lifestyle factors than by a single product. In regulatory and compliance matters, the expert’s familiarity with food-drug-supplement interactions and post-marketing research standards helps counsel evaluate exposure and craft a defensible compliance position. This scientific grounding also strengthens rebuttal strategy when opposing experts overstate what the nutritional evidence can support.

Because nutrition litigation often hinges on how convincingly an expert can explain peer-reviewed science to a judge or jury, selecting the right expert matters as much as the underlying research itself. The experts we can provide include university researchers and clinicians who have published in leading medical journals, led nutrition organizations, and in some cases helped shape FDA policy on ingredient approval and labeling. Round Table Group has completed more than 75,000 expert searches for litigators, and we apply that experience to identify nutrition experts whose credentials and communication skills fit the specific claims at issue in your case. Let us help you find the right nutrition expert for your case by calling us at (202) 908-4500.

Kinds of Cases We Work On

Round Table Group helps our clients find a wide variety of Nutrition expert witnesses for cases like:

01

Nutrient Content Claim Substantiation Anchors a Competitor False Advertising Verdict

A protein supplement manufacturer sued a competitor under false advertising claims, alleging the competitor's new protein bar line advertised a protein content and amino acid profile its own third-party lab testing showed the product did not actually deliver, in a dispute affecting a product category worth tens of millions in annual sales. We identified experts with experience in food and supplement nutrient analysis, protein quality testing methodology, and nutrition labeling substantiation standards. The expert's independent lab testing across multiple product batches confirmed the protein content fell significantly short of the labeled claim, a finding central to the jury's false advertising verdict and the resulting damages award.
02

Claims Substantiation Audit Uncovers Undisclosed Liability in a Food Company Acquisition

The buyer of a functional beverage company sought to rescind part of the purchase price after discovering, post-closing, that several of the brand's marketed health claims lacked the clinical substantiation the seller had represented was on file, exposing the buyer to regulatory and advertising litigation risk. We identified experts with experience in nutrition science claims substantiation, functional food and beverage regulatory standards, and clinical evidence evaluation. The expert found the substantiation file for the brand's flagship claims consisted of preliminary, unpublished data insufficient to meet the level of evidence the seller's own marketing approval process required, a finding that supported the buyer's misrepresentation claim and a negotiated price adjustment.
03

Potency Testing Traces a Supplement Recall to an Ingredient Supplier

A dietary supplement manufacturer sued the supplier of a botanical extract ingredient after finished product testing revealed active compound potency well below label claims across multiple batches, forcing a nationwide recall and retailer chargebacks. We identified experts with experience in botanical ingredient analysis, dietary supplement potency testing, and nutraceutical quality control standards. The expert found the supplied extract lots had potency levels significantly below the supply agreement's specification, a deviation the supplier's own certificates of analysis had misreported, a finding central to the supplier funding the majority of the recall costs.
04

Nutrient Stability Testing Resolves an Infant Formula Contract Manufacturing Dispute

An infant formula brand sued the contract manufacturer producing its product after stability testing on retained samples revealed several key vitamins had degraded below labeled levels well before the product's stated shelf life, triggering a voluntary recall. We identified experts with experience in infant formula nutrient stability, vitamin degradation kinetics, and food manufacturing quality assurance. The expert found the degradation pattern was consistent with a packaging seal defect introduced during a manufacturing line changeover the contract manufacturer had implemented without revalidating shelf-life stability, a finding central to the manufacturer funding the recall and remediation costs.
05

Efficacy Data Review Resolves a Weight Management Product Licensing Dispute

A nutrition company sued the licensee it had partnered with to distribute its meal replacement product line after the licensee withheld royalty payments, alleging the clinical efficacy data supporting the product's weight-loss claims did not meet the substantiation standard the licensing agreement required. We identified experts with experience in weight management clinical research, meal replacement efficacy study design, and nutrition claims evidence standards. The expert found the underlying clinical studies met the level of evidence the licensing agreement specified at the time of execution, a finding central to the arbitration award requiring payment of the withheld royalties.
06

Nutrition Standards Compliance Audit Resolves a School Foodservice Contract Dispute

A school district terminated its contract with a foodservice management company, alleging the vendor's meal planning had systematically failed to meet the federal nutrition standards the contract required, and withheld a substantial portion of final-year payments. We identified experts with experience in school nutrition program standards, menu planning compliance, and federal meal pattern requirements. The expert found the vendor's menus met the required nutrient standards in the large majority of audited weeks, with a smaller subset of documented shortfalls tied to a produce supply disruption the vendor had promptly reported, a finding that narrowed the district's claim and was central to a settlement releasing most of the withheld payments.
07

Performance Claims Review Resolves a Sports Nutrition Sponsorship Dispute

A professional sports organization sued the sports nutrition company it had partnered with in a sponsorship and product supply agreement after several athletes reported adverse reactions to a new recovery supplement, alleging the product's performance and safety claims were not adequately substantiated before launch. We identified experts with experience in sports nutrition product formulation, athlete supplement safety evaluation, and performance claims substantiation. The expert found the supplement's formulation and labeling were consistent with industry-standard safety testing protocols, and that the reported reactions traced to an ingredient interaction with a separate product the athletes had been independently using, a finding decisive in the nutrition company's successful defense.
08

Medical Nutrition Therapy Compliance Review Resolves a Hospital Foodservice Vendor Dispute

A hospital system sued its clinical foodservice vendor after a Joint Commission survey found a pattern of therapeutic diet orders not properly implemented in patient meal delivery, alleging breach of the contract's medical nutrition therapy compliance standards. We identified experts with experience in clinical nutrition therapy, therapeutic diet order implementation, and hospital foodservice quality standards. The expert found the implementation failures were concentrated in a diet order category the hospital's own electronic health record interface had failed to transmit correctly to the vendor's kitchen system, a finding that shifted responsibility back onto the hospital and substantially reduced the vendor's exposure.
09

Ingredient Claims Substantiation Review Resolves a Functional Food Licensing Dispute

A food ingredient technology company sued the licensee it had partnered with to incorporate its proprietary fiber ingredient into a branded snack line after the licensee stopped paying royalties, alleging the ingredient's digestive health claims lacked adequate clinical substantiation as represented in the licensing agreement. We identified experts with experience in dietary fiber physiology, digestive health claims research, and functional ingredient substantiation standards. The expert found the licensor's clinical dossier met the substantiation standard the agreement specified, based on peer-reviewed research consistent with the claims made, a finding central to the arbitration award requiring payment of the disputed royalties.
10

Nutrient Degradation Analysis Resolves a Food Fortification Supply Chain Dispute

A cereal manufacturer sued the ingredient supplier providing its vitamin and mineral fortification premix after finished product testing revealed several fortified nutrients had degraded below labeled levels during normal shelf storage, triggering a costly product recall. We identified experts with experience in food fortification chemistry, micronutrient stability, and premix formulation standards. The expert found the premix formulation supplied did not include the stabilizing coating the supply specification required for the nutrients in question, a formulation deviation central to the supplier funding the recall costs.
