Vetri Disc combines bovine tracheal cartilage with amino acids, mineral sulfates, vitamins, pepsin, and horsetail rush (Equisetum arvense) to support back health and the spine's connective tissues. Bovine tracheal cartilage is a rich source of chondroitin sulfates which comprise the connective tissue matrix and are found in an especially high concentration in the spinal and invertebrate disc tissues. Taurine and horsetail rush are necessary for the synthesis of connective tissue while minerals like calcium and magnesium support bone growth and maintenance. Zinc is necessary for tissue respiration and plays a key role in the body's healing process. Amino acids such as serine link the glycosaminoglycan structure to connective tissue proteins, and vitamins C and D support collagen production and calcium absorption.
