Pharmaceutical giant GlaxoSmithKline is facing a $217,000 lawsuit after a couple of high school students discovered it was misleading consumers with one of its most popular products.

According to New Zealand news reports, two 14-year-old students were testing fruit juices as part of a science project to determine their vitamin C content. To their surprise, Ribena, a supposedly highly nutritional fruit drink made by UK-based GlaxoSmithKline, contained no vitamin C, although the product label stated “the blackcurrants in Ribena have four times the vitamin C of oranges.” Interestingly the students learned that not only was the drink void of vitamins, it did not contain any blackcurrants.

Parents throughout the United Kingdom, Australia and New Zealand, as well as numerous other countries, have been giving their children Ribena for several years believing that they were enhancing their children’s health. The fact that this product was targeted towards children makes this case one of the worst cases of false marketing in history.

As an interesting aside, GlaxoSmithKline is also the manufacturer of the first United States Food and Drug Administration approved non-prescription weight loss supplement – Alli. The diet pill assists weight loss by blocking the absorption a portion of fat consumed. It is expected to be on store shelves this summer.
