In June 2019, a class-action lawsuit
was filed against Walmart for allegedly falsely stating on the label of Spring Valley Glucosamine Sulfate that each tablet contains 1000 mg of glucosamine sulfate when, according to plaintiffs, the product actually contains glucosamine hydrochloride instead of glucosamine sulfate.
