The Krishnan v Jamieson Laboratories case is a class action lawsuit that alleges that the defendants manufactured and sold products labeled as containing glucosamine sulfate, but which in fact did not contain any glucosamine sulfate at all. The plaintiff claims that the defendants engaged in negligent misrepresentation, unjust enrichment, and violated the Competition Act and provincial consumer protection legislation.
The case was filed in 2019 in the Supreme Court of British Columbia and involves several defendants, including Jamieson Pharmaceuticals Ltd., WN Pharmaceuticals Ltd., Natural Factors Nutritional Products Limited, and various pharmacies and retailers. The case was certified as a class proceeding against WN Pharmaceuticals Ltd. and Natural Factors Nutritional Products Limited in July 2021, and against Jamieson Pharmaceuticals Ltd. in November 2021. A settlement was reached with Vita Health Products Inc. and Sisu Inc., two other defendants, in June 2021.
The class action covers all residents of Canada who purchased a product labeled as containing glucosamine sulfate, glucosamine sulfate potassium chloride, glucosamine sulfate KCL, or glucosamine sulfate • KCL, for personal, family or household purposes, that was manufactured by one of the defendant manufacturers, on or after May 6, 2004.
