The U.S. Food and Drug Administration and Rexall, Inc., of Deerfield Beach, Fla., have issued a recall alert for one lot of the company's calcium supplements. The bottles of Rexall Calcium 1200 mg plus 1000IU Vitamin D3 actually contain tablets of triple strength glucosamine chondroitin, which are derived from crustacean shells and may be harmful to consumers with shellfish allergies.

The FDA says the recall affects only one lot of Rexall supplements which were sold exclusively at 9,800 Dollar General stores across 38 states. And while there have been no reports of illness or injuries from the pill mix-up, the FDA and Rexall have pulled all the affected bottles of Rexall calcium supplements from store shelves.

Recalled bottles of Rexall Calcium 1200 mg plus 1000IU Vitamin D3 can be identified by UPC code (3 01220 452113) and Lot number (387651-04) and bear an expiration date of 08/15.

Consumers who have the recalled Rexall supplements are advised to return the product to Dollar General for a full refund or call Rexall (toll-free: 888-534-6370) for more information.
