It has been informed that improvement has been seen in the stocks of supplements retailers The Vitamin Shoppe and GNC Holdings. The Vitamin Shoppe is a New Jersey-based retailer of nutritional supplements and GNC Holdings is a commercial enterprise that is concentrated on the retail sale of health and nutrition-related products, involving vitamins and supplements.

An announcement has been made by New York Attorney General Eric Schneiderman that his office is heading an alliance of state attorneys general to increase his assessment of the industry so that transparency can be improved and also to make sure that the products really contain what their labels claim to contain, and nothing more.

The attorneys general of three states have been involved in the coalition. The states are New York, Connecticut, and Indiana. Last month, an announcement was made by Schneiderman that tests solicited by his office found that almost four in every five herbal supplements that tested at major retailers in New York didn't have the ingredients that claimed on the label.

It has been revealed that over a third of them had contaminants like rice, pine, beans, and asparagus. Office of Schneiderman informed that the supplements were bought at GNC, Target, Wal-Mart, Walgreen's.

Those retailers were ordered by Schneiderman to stop selling some store-brand supplements, like ginseng, St. John's Wort, Echinacea and garlic. Schneiderman also asked information from the companies regarding how those products are processed.

The Council for Responsible Nutrition said that the tests used were incorrect. Wal-Mart said that the products it removed from shelves has correctly labeled ingredients and are safe. GNC said that the Herbal Plus brand products that included in letter of Schneiderman will be back as soon as possible.
