Ultra Joint Forte contains a combination of glucosamine, chondroitin, methylsulfonylmethane (MSM), and astaxanthin. Glucosamine HCl is a well-absorbed source of glucosamine, an important precursor for the synthesis and maintenance of connective tissues. Chondroitin sulfate also supports formation of connective tissues, primarily joint cartilage, and helps support existing cartilage. MSM, a derivative of DMSO, is a naturally occurring compound of biologically available sulfur. Astaxanthin is a natural carotenoid that can help modulate the body's normal regulatory response.
