This shellfish-free formulation provides the raw material for the production of cartilage and collagen, Glucosamine MSM Complex is one of Solgar's premium joint health supplementsAn advanced formulation that provides the key raw materials for cartilage support. Both the glucosamine and MSM are derived from vegetable sources, making it suitable for vegans and those with shellfish allergies. MSM is a source of organic sulphur, which is important for the formation of collagen, a strong fibrous protein that forms a flexible matrix - the foundation of cartilage tissue. MSM is therefore necessary for cartilage integrity and is an important factor in the maintenance of joint tissue. 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). The addition of vitamin C, manganese, white willow extract and ginger extract further enhance the cartilage supportive properties of this formula. The well-documented benefits of glucosamine, combined with the synergistic action of MSM, vitamin C, manganese, white willow and ginger extracts makes this complex the ideal choice for anyone looking to support joint health and maintain flexibility, especially amongst vegetarians, vegans and those with shellfish allergies.DosageThree tablets daily, preferably at mealtime, or as directed by a healthcare practitioner.Ingredients:Ingredients: Three (3) tablets provide: Vegetarian Glucosamine (as glucosamine HCI) 1500 mg MSM (as methylsulfonylmethane) 1000 mg White Willow 5:1 Extract 100 mg (equivalent to 500 mg of White Willow Powder) Ginger 4:1 Extract 108 mg (equivalent to 432 mg)
