Flex, Maximum Flexibility, Item number 21-601, dietary supplement, 90 capsules per bottle. The Flex product is a dietary supplement in capsule form containing vegetable glucosamine HCL, chondroitin sulfate (shark cartilage), organic microalgae (aph. flos-aquae) and chicken cartilage. The serving size is 3 capsules and the suggested use is one 3 capsule serving per day.

New Algae Company recalled Flex, Maximum Flexibility in a Class I action — the FDA's most serious tier, reserved for products with a reasonable probability of causing serious health consequences or death on Oct 23, 2013.

The FDA listed the reason as an undeclared allergen: "Flex dietary supplement product is recalled because the finished label does not declare shark cartilage." Allergen mislabeling is the leading cause of U.S. food recalls, because a missing declaration can trigger a reaction in someone who reads the label and believes the product is safe.

Distribution was broad: the FDA record describes it as "Distributed nationwide," which places this among the wider-reach recalls on the site. Consumers across the affected area should check product on hand. The recalling firm is based in Klamath Falls, OR. The recall covers 103 bottles (90 capsules per bottle) of product. The FDA has Terminated this recall (first reported Nov 27, 2013), its final lifecycle state, indicating the agency considers the corrective action resolved. The historical record remains useful for tracking a brand's recall pattern over time.
