Walgreen named in class action lawsuit over false advertising of Finest Nutrition glucosamine supplements


According to the complaint, consumers across the country purchased more than $130 billion of dietary supplements in 2016. One of the most popular dietary supplements is glucosamine, which some marketers believe will grow to a market of more than $750 million by 2022.

Glucosamine is commonly sold in two formulations: glucosamine sulfate and glucosamine hydrochloride which have unique molecular structures. As alleged, many consumers prefer glucosamine sulfate because it is believed to be the more effective version of glucosamine. It also commands premium prices compared to glucosamine hydrochloride.

Plaintiff purchased a bottle of Finest Nutrition brand glucosamine sulfate, which states in large font on the label that each serving contains 1000 mg of glucosamine sulfate. However, laboratory testing confirms that the product actually contains Glucosamine Hydrochloride and does not contain any Glucosamine Sulfate. Accordingly, according to the complaint, Walgreens is selling a dietary supplement that simply is not what it claims to be.
