Qunol Magnesium Supplement Labeling Class Action Lawsuit

Cohen et al. v. Quten Research Institute, LLC
Case Information

• Case Number: 23-cv-07183
• Case Status: Case is in progress
• Court: United States District Court, District of New Jersey
• Filed: March 29, 2023

Lemberg Law represents a putative class of supplement purchasers in a lawsuit against Quten Research Institute, LLC, alleging that the company has falsely labeled its “Extra Strength” magnesium dietary supplements. The supplements, marketed as containing 420 mg of magnesium per serving (from magnesium glycinate), allegedly fail to meet the stated magnesium content.

Complaint

The complaint alleges that Quten’s magnesium supplements cannot physically contain the advertised magnesium amount due to the following:

1. 1. Capsule Capacity Limits:
      • Quten uses size 00 capsules, which hold a maximum of 1,092 mg of powder each. Two capsules can fit no more than 2,184 mg of powder.
      • Magnesium glycinate consists of only 14.1% elemental magnesium, meaning approximately 3,000 mg of magnesium glycinate is needed to yield 420 mg of elemental magnesium. This exceeds the physical capacity of the capsules.
   2. False Advertising:
      • The front and back labels of the supplements prominently claim 420 mg of magnesium “as Magnesium Glycinate” per serving, which plaintiffs argue is impossible given the above facts.
      • The supplement also contains other ingredients, such as gelatin and magnesium stearate, further reducing the available space for magnesium glycinate.
   3. Inferior Ingredients:
      • Plaintiffs suspect the supplements contain magnesium from cheaper, less absorbable sources, such as magnesium oxide, instead of magnesium glycinate.

Manufacturer Response

Quten denies the allegations, arguing the claims are based on a “lack of substantiation” rather than affirmative evidence of falsity. However, plaintiffs counter that the claims are rooted in the mathematical impossibility of the stated magnesium content.

Relief Sought

The plaintiffs and the class members are seeking:

• Compensation: Refunds for purchases, along with damages for misleading advertisements and breach of warranty.
• Injunctive Relief: A cessation of false advertising practices (withdrawn during the proceedings).
• Punitive Damages: For knowingly misleading consumers and violating federal and state laws.
