Proto-Flex is a combination of three key ingredients that support healthy joint structures and function, as well as joint comfort. With glucosamine, an essential building block for the formation of the main components of cartilage tissue, and hyaluronic acid, an important constituent of joint fluid that serves as a lubricant and plays a role in resisting compressive forces, this product promotes the maintenance of healthy joint structures.

AprèsFlex^®, a proprietary Boswellia extract, has been included to assist in the maintenance of healthy joints and to help to relieve occasional minor pain resulting from overexertion or stress.
