ChondroGuard contains chondroitin sulfate and a complex of vitamins and minerals that participate in the repair and maintenance of connective tissue. Bovine tracheal cartilage provides a clinically tested source of chondroitin sulfate, which is an important precursor for re-synthesis of disrupted or decomposed connective tissue structures. Vitamins A, B5, C and E, and the minerals zinc, copper, and manganese are included to prevent deficiencies known to impair tissue healing. Vitamin C appears to have further benefits as a protector of joint tissues subjected to excessive wear and tear. Vitamins B1, B6 and B12 also have important roles in the healing process, and appear to optimize healing activity in spinal tissues. Equisetum (horsetail) is added as a botanical source of organic silicon, which is believed to have an important function in the formation and maintenance of connective tissue.
