Purified Chondroitin Sulfates supplies purified chondroitin sulfate along with SOD and catalase, important antioxidant enzymes. Chondroitin sulfates (CS) function as structural components of tunica intima, giving strength and elasticity to blood vessels. With aging, CS are gradually replaced by other glycoaminoglycans (GAGs), affecting vascular permeability. Deranged turnover and synthesis of CS in vascular intima are some of the earliest changes seen in this process. Another important role for CS is the activation of lipoprotein lipase on capillary endothelial cells, facilitating proper metabolism of blood lipids. During repair of injured connective tissue, CS synthesis precedes collagen synthesis. Consider as supplemental support for healthy discs and connective tissue, and as support for vascular integrity.
