Lawsuit Investigation: Glucosamine Supplements

This Alert Affects:

Anyone who purchased glucosamine supplements.

What's Going On?
Attorneys working with ClassAction.org have reason to believe some of these supplements contain no actual glucosamine sulfate. They are investigating whether a class action lawsuit can be filed.
What Brands Are Under Investigation?
GNC, Walmart's Spring Valley, Dollar Tree's Nature's Measure, The Vitamin Shoppe, CVS, Walgreens' Finest Nutrition, Whole Foods and more. See the full list below.
What You Can Do
Fill out the form on this page and tell us which supplement you bought. Before the attorneys can even consider filing a lawsuit, they first need to hear from consumers who purchased the products.

Attorneys working with ClassAction.org would like to hear from anyone who purchased glucosamine supplements sold under the following brand names: 

  • Walmart's Spring Valley 
  • GNC
  • CVS Health
  • Dollar Tree's Nature’s Measure 
  • Walgreens’ Finest Nutrition 
  • Whole Foods’ 365 Everyday Value 
  • Healthy Sense
  • Nature’s Bounty 
  • Solaray
  • MRM
  • Natural Factors
  • Fresh Thyme Farmers Market

  • Signature Care
  • Jarrow Formulas
  • Vitamin Shoppe  
  • Kroger 
  • Food Science Corp.'s DaVinci Laboratory
  • Doctor's Best 
  • Nature's Way 
  • Safeway 

The attorneys have reason to believe that supplements sold under these brand names don’t contain any glucosamine sulfate. They want to determine whether class action lawsuits can be filed – but first need to speak with people who bought the products.

If you purchased a glucosamine supplement made by any of these companies, fill out the form on this page.

Any information you provide can be helpful to this investigation. If a class action lawsuit is filed and is successful, consumers may be able to get their money back for the products they purchased.  

Why Are These Supplements Under Investigation?

Attorneys suspect that these products may be mislabeled. Specifically, they believe that what companies are selling as glucosamine sulfate is actually glucosamine hydrochloride – a cheaper and inferior product. In fact, they have test results from independent labs that indicate some of these manufacturers' supplements contain no glucosamine sulfate.  

Glucosamine Sulfate vs. Glucosamine Hydrochloride: What’s the Difference?

First off, glucosamine hydrochloride is much cheaper to produce and has a different molecular structure. Second, studies have revealed that nearly any benefit glucosamine can have on joint health comes from glucosamine sulfate – not glucosamine hydrochloride.

How a Class Action Lawsuit Can Help

With manufacturers allegedly labeling products that are really glucosamine hydrochloride as glucosamine sulfate, attorneys suspect that consumers are getting ripped off and paying for a product that isn’t what it claims to be. A class action lawsuit could help these individuals get their money back for the supplements they purchased. Furthermore, a class action could help hold these companies accountable and ensure appropriate labels are used in the future.

If you purchased a glucosamine supplement, help with this investigation by filling out the form on this page and telling us which product you bought. After you get in touch, an attorney may reach out to you directly. He or she can explain how you may be able to participate in a potential class action lawsuit to get your money back.
