The Body Fortress lawsuits were a series of class actions filed beginning in 2014 that accused the makers of Body Fortress Super Advanced Whey Protein of “protein spiking,” which is the practice of adding cheap nitrogen-rich ingredients so a powder tests higher for protein than it actually contains. The cases moved through federal courts in New York and Illinois, ended in undisclosed private resolutions without a certified class, and prompted the manufacturer to reformulate the product and cut its labeled protein count.
The Core Allegation: Protein Spiking
Protein content in supplements is typically measured using the Kjeldahl method, which calculates protein by measuring total nitrogen. Because all amino acids contain nitrogen, adding inexpensive free-form amino acids or other nitrogen-rich compounds to a powder raises the nitrogen reading and inflates the protein number that ends up on the label.1PubMed Central (PMC). Protein Spiking and Mid-Infrared Spectroscopy Analysis
The substances most often used for this include L-glycine, L-taurine, L-glutamine, and creatine monohydrate. They cost far less than intact whey protein, and free-form amino acids do not function like complete proteins in the body. They are generally considered poor stimulators of muscle protein synthesis.1PubMed Central (PMC). Protein Spiking and Mid-Infrared Spectroscopy Analysis
That is the practice consumers alleged was happening inside their tubs of Body Fortress.
The First Suit: Mencer v. NBTY (2014)
The first class action landed on August 25, 2014, in the U.S. District Court for the Eastern District of New York. Mencer et al v. NBTY, Inc., United States Nutrition, Inc., and Healthwatchers, Inc. (Case No. 14-cv-05030) was brought by Parker Waichman LLP, Seeger Weiss LLP, and Barbat, Mansour & Suciu PLLC.2PRWeb.

The complaint said Body Fortress Super Advanced Whey Protein claimed 30 grams of protein per serving on the label, but independent testing showed only 21.5 grams of actual whey protein once the spiking agents were stripped out. The roughly 28 percent gap was attributed to free-form amino acids including glycine, threonine, L-glutamine, leucine, valine, and isoleucine, along with taurine and creatine monohydrate.2PRWeb.

The case did not last long. Between February and March 2015, all named plaintiffs voluntarily dismissed their claims. Three were dismissed without prejudice in February; the rest told the court they had “reached a settlement” before their claims were also dismissed without prejudice in March.3CourtListener.

The Bigger Case: Porter v. NBTY (Illinois)
A second and more consequential lawsuit followed in 2015 in the U.S. District Court for the Northern District of Illinois. Porter et al v. NBTY, Inc. (Case No. 15-cv-11459) named four defendants: NBTY, Inc., United States Nutrition, Inc., Healthwatchers (DE), Inc., and Met-RX Nutrition, Inc. Plaintiffs Ryan Porter and Haarin Kwon raised the same protein spiking theory, but they went further, challenging not just the protein quantity but also how the product’s source and quality were represented.5GovInfo. Porter v. NBTY, Inc., Memorandum Opinion and Order
An amended complaint in May 2016 covered Body Fortress Super Advanced Whey Protein, Body Fortress Super Advanced Whey Isolate, and Met-Rx MyoSynthesis Whey, alleging misrepresentations about protein content, percentage of daily value, and the sources and quality of the protein.6Truth in Advertising.

2016 Partial Dismissal
In November 2016, the court trimmed the case. Claims tied to products the plaintiffs had not personally bought (the Body Fortress Whey Isolate and the Met-Rx product) were dismissed. The false advertising claims about Body Fortress Super Advanced Whey Protein were allowed to move forward.6Truth in Advertising. Body Fortress Protein Supplements
2019 Summary Judgment Ruling
After years of discovery, Judge Manish S. Shah ruled on the defendants’ motion for summary judgment on November 4, 2019. It was a mixed outcome.
The court dismissed the claim tied to the “percentage of daily value” column on the nutrition panel. Both Porter and Kwon had testified in depositions that they never looked at those figures, so they could not tie that specific representation to their purchases.5GovInfo. Porter v. NBTY, Inc., Memorandum Opinion and Order
Two categories of claims survived. The challenge to the front-label “60g Premium Protein” statement remained viable; because it sat outside the standardized nutrition panel, the court held it was subject to federal nutrient-content claim regulations and could be attacked as false if spiking had inflated the number. The challenge to the product name itself, “Body Fortress Super Advanced Whey Protein,” also survived, with the court finding the plaintiffs had adequately alleged the name misled consumers into thinking the product was made only from pure whey rather than a blend that included non-protein nitrogen sources.5GovInfo.

No class had been certified by the time of that ruling; a certification motion was still pending.7Justia. Porter v. NBTY, Inc., Memorandum Opinion and Order
Case Termination
The docket shows Porter v. NBTY was terminated on December 31, 2019, less than two months after the summary judgment ruling. No trial occurred, and no public record of a settlement or further opinion has been identified.8CourtListener. Porter v. NBTY, Inc. Docket The quick close following a ruling that had preserved the strongest claims is consistent with a private resolution, but the terms were not disclosed.
Other Lawsuits Against Body Fortress
Two separate lines of litigation targeted the brand for reasons unrelated to protein spiking, and they are worth knowing about because search results often lump them together.
On packaging, plaintiffs Matthew Gates and Carlos Solis filed Gates et al v. NBTY, Inc. and United States Nutrition, Inc. (Case No. 16-cv-2090) in the Southern District of California in 2016. The suit alleged that Body Fortress and Pure Protein tubs contained more than 37 percent empty space, misleading consumers about how much product they were buying.9Truth in Advertising.

The plaintiffs alleged that claims about supporting muscle growth and faster recovery lacked scientific support.11Truth in Advertising. Body Fortress 100% Pure Glutamine Powder
How Body Fortress Fit an Industry Pattern
Body Fortress was one of several supplement brands hit with protein spiking suits in this period. A 2015 case against MusclePharm’s “Arnold Schwarzenegger Series Iron Mass” alleged the product contained roughly half of its labeled 40 grams of protein. A district court dismissed the case as preempted by FDA rules, but the Ninth Circuit partly reversed in 2018. The appeals court drew a line that shaped these cases: federal law preempted challenges to the measured amount of protein, because FDA regulations permit nitrogen-based calculations, but it did not preempt challenges to the source of the protein when the label implied specific high-quality ingredients.12Top Class Actions.

Similar suits also targeted 4 Dimension Nutrition, GNC, CVS Health, and Inner Armour. By early 2015 the 4 Dimension/GNC case had been voluntarily dismissed, and the others were still in early stages with defendants denying the allegations.13Forbes.

What Changed About the Product
Body Fortress moved quickly after the first lawsuit. By September 2014, the company had released what it called a “new and improved” version of its Super Advanced Whey Protein. The updated label showed 20 grams of protein per serving, down from 30. The new formula reportedly listed a separate “Super Recovery Blend” of creatine, taurine, and glutamine at 3 grams, keeping those ingredients visible but distinct from the protein count.14PricePlow Forum.

Since then, the brand has obtained NSF Certified for Sport certification across its core line. As of 2026, nine Body Fortress products are listed in the NSF International database, including multiple flavors of the Super Advanced Whey Protein, the Super Advanced Isolate Protein, the Super Advanced Mass Gainer, and the 100% Pure Glutamine Powder.15NSF International. NSF Certified Dietary Supplement Listings – Body Fortress Independent third-party lab testing by Ellipse Analytics, commissioned by Garage Gym Reviews, gave the vanilla flavor of the whey protein an “Excellent” rating for label accuracy, placing it in the top 10 percent of more than 150 protein powders tested.16Garage Gym Reviews.
