TruHeight sues three Amazon sellers over height supplement advertising

The complaints

Vanilla Chip LLC, d/b/a TruHeight v. Postolenko Olena, individually d/b/a Biotequelab Store, and Natalia Khazhanets, individually dba BTQ Vitamin Store, No. 2:26-cv-03621, and Vanilla Chip LLC, d/b/a TruHeight v. Yuliia Sikotovska, individually d/b/a SOLACEROOT STORE, No. 2:26-cv-03627 (D. Nev.), are two nine-page complaints filed November 2, 2026, each at ECF No. 1. They follow the same template. Vanilla Chip, a Nevada limited liability company based in Las Vegas, says it does business as TruHeight and markets pediatric and adolescent nutritional supplements through its website and Amazon. Each complaint identifies the individual defendants as the persons operating the named Amazon stores, according to Amazon seller disclosures, and gives them addresses in Ukraine. (Compl., No. 03621, paras. 2 to 4, 8; Compl., No. 03627, paras. 2, 3, 7.)

What the complaints allege

In No. 03621, TruHeight alleges that as of September 25, 2026 and September 30, 2026 the defendants advertised two height-growth supplements on Amazon with claims including "CLINICALLY PROVEN HEIGHT GROWTH & BONE DENSITY ENHANCEMENT," "NO SIDE EFFECTS" and maximum height or growth speed in six months, one listing marked "Recommended for adults" and the other aimed at adults, teens and children aged five and up. In No. 03627, it alleges that as of October 7, 2026 the defendant advertised height growth gummies with melatonin, aimed at children aged five and up and at teens, with claims including "HEIGHT GROWTH IN YOUR SLEEP," a "PROVEN FORMULA" to promote body height growth, "SAFE AND EFFECTIVE FOR AGES OVER 5+ YEARS" and maximum growth speed in six months, and it alleges the product's Supplement Facts panel lists no calcium or other bone-building mineral. TruHeight alleges the statements are literally false or misleading, that nutritional supplements cannot cause longitudinal bone growth in adults with fused growth plates or in teens and children, and that the defendants lack competent and reliable scientific evidence for the "proven" claims. It alleges the products compete with its own and that it lost sales and suffered price erosion and reputational harm. It says it sent a cease-and-desist demand on August 27, 2026, that the defendants did not respond by September 6, 2026, and that the advertising remained available at filing. (Compl., No. 03621, paras. 9 to 45; Compl., No. 03627, paras. 8 to 33.)

Claim and relief requested

Each complaint pleads one count of false advertising under Lanham Act section 43(a)(1)(B), 15 U.S.C. § 1125(a)(1)(B). Each says TruHeight seeks injunctive relief under 15 U.S.C. § 1116 and monetary relief under 15 U.S.C. § 1117(a). TruHeight asks for an injunction against publishing the identified statements, an order to remove or correct the advertising and to request correction of content supplied to Amazon, its damages and the defendants' profits attributable to the violation, interest, attorneys' fees under 15 U.S.C. § 1117(a), and other appropriate relief.
