Ultra Cruz equine chondroitin sulfate is a powder formula designed to support healthy joints and cartilage in Horses. Although cartilage is a very resilient tissue and can tolerate considerable stress and heavy loads, it has no blood vessels or nerves and therefore has a limited healing ability when injured. Chondroitin sulfate is a naturally occurring sulfated glycosaminoglycan found in aggregate, and it is a crucial constituent of connective tissue and cartilage where it provides structure, resistance, and holds water and nutrients.
