Ultra Cruz Equine Glucosamine is designed to support healthy joints and cartilage. 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 the tissue is injured. Glucosamine is an amino-sugar that is involved in the synthesis of glycosaminoglycan's (gauges), which give Rise to the cartilage matrix. Glucosamine and chondroitin sulfate are reagents that may aid in the synthesis of gauges and proteoglycans, thereby supporting joint health.
