Nutrition Information

Glucosamine hydrochloride (HCl) and Chondroitin sulphate are well documented joint health ingredients used by the body to help maintain articular cartilage and joint function. These are complemented by Hyaluronic acid, which works within the joint capsule to stabilise the joint and aid shock absorption, and Methyl sulphonyl methane (MSM), which supplies sulphur that is required to provide strength to articular cartilage, and has antioxidant properties. In addition to these, a generous helping of Rosehips is included, a powerful natural antioxidant for optimum joint health to help with tired joints, caused by age or wear and tear. These Rosehips provide naturally occurring Vitamin A, C and K to help potentiate the effects of the nutraceuticals, optimising the formation of cartilage and connective tissue.
