Vitreoclar Plus, 4x30 tablets, Sifi Food supplement with Glucosamine sulfate, Hydrolyzed collagen, Grape seed extract, Vitamin E. Benefits: Glucosamine and collagen are part of connective tissue. Connective tissues (which include the vitreous body of the eye) are made up of specialized cells, a fibrillar matrix, and water. The fundamental components of the matrix are collagen, hyaluronic acid and proteoglycans. These fibrillar molecules fulfill the role of support but, physiologically, are subject to oxidative or enzymatic degradation processes, balanced by a continuous synthesis. With aging or under certain other conditions, degenerative processes exceed those of synthesis, which makes it necessary to slow down degeneration and stimulate synthesis. In particular, chondroitin sulfate and glucosamine act synergistically, being fundamental substances for the structure of connective tissues and for enzymatic action. The Vitreoclar+ formula also incorporates grape seed extract (Vitis vinifera), with high antioxidant activity, able to counterbalance the harmful effects of free radicals.
