Up to $800 VSL#3 Probiotic Settlement: How to Claim

What happened

Class period: June 1, 2016 through June 19, 2019

• VSL#3 is a probiotic supplement sold in the United States
• Plaintiffs say the companies told buyers the formula they were selling had been proven effective in clinical tests for certain medical conditions, and that the claim was false
• Plaintiffs also say buyers overpaid for the product because of that marketing
• The defendants are VSL Pharmaceuticals, Inc., Leadiant Biosciences, Inc., and Alfasigma USA, Inc., the companies that licensed, marketed, and sold VSL#3
• The defendants deny doing anything wrong, and the court has not ruled on who is right
• The case is Starr v. VSL Pharmaceuticals, Inc., Case No. 8:19-cv-02173-LKG, in the United States District Court for the District of Maryland
• The parties agreed to a $20,000,000 settlement fund to end the case
