There is no Intek Evolution protein lawsuit on record. Searches for one appear to conflate Intek Nutrition’s Evolution-branded protein powders with a wave of class-action lawsuits filed against other supplement companies between 2014 and 2016 over a practice called protein spiking. Intek Nutrition and its Evolution products are not named as defendants in that litigation or in any consumer class action turned up by available court records and reporting.
What Intek’s Evolution Products Are
Intek Nutrition, which operates as Intek Advanced Body Solutions, uses “Evolution” as a brand modifier across several product lines. The protein powders under that name include Protein Evolution, marketed as a “5 source blended protein shake,” and Isolate Evolution, a whey isolate and hydrolysate blend advertised at 30 grams of protein per serving.1Intek Nutrition. Protein Evolution2Intek Nutrition. Isolate Evolution The company states its products contain “no added fillers, fats, or sugars” and are made in cGMP-certified facilities in the United States. The Evolution name also appears on non-protein items in the catalog, including BCAA, detox, and testosterone-support products.3Find Your Healthy Place. Intek Nutrition Products
The Protein Spiking Lawsuits Searchers Are Probably Thinking Of
Between 2014 and 2016, plaintiffs’ attorneys filed a string of class actions accusing supplement companies of “protein spiking,” also called amino spiking. The claim: manufacturers padded their powders with cheap, nitrogen-rich ingredients so that standard lab tests would register a higher protein number than the product actually delivered. Because the Kjeldahl and Dumas tests measure total nitrogen and convert it to protein, adding free-form amino acids like glycine and taurine, or substances like creatine and maltodextrin, can inflate results without adding equivalent complete protein. Whey concentrate costs roughly $5 to $6 per pound; the fillers can run under $1 per pound.4Forbes. Lawsuits Say Protein Powders Lack Protein, Ripping Off Athletes
The first case was filed in August 2014 by attorney Nick Suciu III against NBTY and its subsidiaries over Body Fortress Super Advanced Whey Protein, which independent testing said contained about 21.5 grams of protein per serving instead of the labeled 30.5New Hope Network. Lawsuits Target Protein Spiking Similar suits followed against:
- Giant Sports, over its Giant Delicious Protein Blend.
- MusclePharm, over the Arnold Schwarzenegger Series Iron Mass, which allegedly delivered 19.4 grams of protein versus 40 grams claimed.6ClassAction.org. Amino Spiking Lawsuit
- CVS Health, over its store-brand Whey Protein Powder.
- Inner Armour (IA Nutrition), over five products including Mass Peak.
- Iovate, over MuscleTech, Six Star, EPIQ, and fuel:one brands.7PricePlow. MuscleTech Amino Acid Spiking Settlement
Intek Nutrition does not appear on that list, or in any parallel filing surfaced by reporting on the litigation wave.
How Those Cases Ended
Most of the protein spiking suits ended quietly and inconsistently. The Body Fortress case was dismissed in early 2015 after the named plaintiffs withdrew their claims, with no public explanation.8Truth in Advertising.

The clearest consumer payout came out of the Iovate case: a $2.5 million settlement fund covering MuscleTech, Six Star, EPIQ, and fuel:one buyers, with up to $300 per household for claimants with proof of purchase and $10 per product (capped at $50 per household) for those without receipts.7PricePlow.

The One Court Case With “Evolution Nutrition” in the Caption
If you go looking through federal dockets, one case does surface with that name attached: Evolution Nutrition, Inc. v. Incline Health, Inc., filed in the Southern District of California in 2017 (Case No. 3:17-cv-01368). It is not related to Intek Nutrition and it is not a consumer class action over protein spiking. It was a dispute between two companies that settled; the parties filed a joint notice of settlement in April 2018, and the court dismissed all claims and counterclaims with prejudice on April 20, 2018, with each side bearing its own fees.12CourtListener. Evolution Nutrition, Inc. v. Incline Health, Inc. The settlement terms were not made public, and nothing in the docket ties the case to protein content or labeling claims.
Where Protein-Content Claims Stand Now
The regulatory question at the heart of the spiking suits was never rewritten. FDA rules still allow protein content to be calculated from total nitrogen without subtracting non-protein nitrogen sources. Voluntary industry guidelines issued in 2014 by the American Herbal Products Association and the Council for Responsible Nutrition recommended subtracting non-protein nitrogen, but they carry no legal force.13Supply Side SJ.

The bigger shift came in August 2023, when the Ninth Circuit ruled in Nacarino v. Kashi Co. and Brown v. Kellogg Co. that state-law challenges to protein claims are preempted by federal law when a manufacturer uses the nitrogen method and includes the required quality-adjusted protein percentage in the Nutrition Facts Panel.14U.S. Court of Appeals for the Ninth Circuit. Nacarino v. Kashi Co. and Brown v. Kellogg Co. State-law claims may still proceed if a label uses modifying language like “high-quality protein” or “digestible protein,” or if a company omits the quality-adjusted daily value figure from the Nutrition Facts Panel. Straightforward “X grams of protein” claims calculated via the nitrogen method are, under that ruling, difficult to challenge under state consumer protection statutes.15Covington & Burling.

The short version for anyone searching this out: Intek Nutrition’s Evolution protein powders have not, based on the available record, been the subject of a lawsuit. The search interest reflects an era when the whole category was under scrutiny, not a case against this particular company.
