Solgar Glucosamine HCl 1000mg (Shellfish-Free) Glucosamine HCl 1000mg (Shellfish-Free) is a glucosamine product that is suitable for vegans and those with shellfish allergies. Glucosamine provides raw material for the production of proteoglycans and glycosaminoglycans (GAGs), important structural components of cartilage. An increase in glucosamine in the diet correlates to an increase in the production of glycosaminoglycans with subsequent increased water retention in the cartilage matrix (water retention is key to the cushioning properties of cartilage). In addition, supplemental glucosamine appears to stimulate collagen production by the chondrocytes (cartilage cells) as well as promoting normal chondrocyte metabolism, all of which serves to promote healthy cartilage and maintain optimal joint function. As one of the most-researched joint health nutrients, glucosamine has always been a popular choice amongst those looking to maintain flexibility and promote joint health, and with the introduction of this shellfish-free glucosamine, more people than ever before are able to use it. Glucosamine HCl provides raw material for the production of structural components of cartilage.
