Using the most concentrated and easy to absorb form of high grade glucosamine hydrochloride, this supplement provides the building blocks to manufacture collagen and proteoglycans in the joint cartilage and the synovial membrane which produces the fluid lubricating the joints. Chondroitin has an additive effect alongside glucosamine helping to maintain flexibility and mobility. Both ingredients are from sustainable sources. Can be used with Garlic & Fenugreek Tablets and Green Releaf Tablets.
