Glucosamine is an amino sugar found mainly in body tissues. it plays an important role in the formation of synovial fluids, tendons, ligaments, skin & bones. It's this formation of tissues that are used in the joints that makes glucosamine so useful in the treatment of osteoarthritis, joint mobility, joint pain & general joint health. A little known but important fact about glucosamine is its use in the formation of heart valve & blood vessel tissue, also making it very important for people with Heart & Circulatory problems. Chondroitin is a major constituent of cartilage, providing structure & holding water & nutrients. It also allows other molecules to pass through the cartilage, which is very important as there is no blood flow to cartilage. Because of it's actions Chondroitin is a great compliment to Glucosamine. Glucosamine/ Chondroitin provides 500mg of Glucosamine Sulphate combined with 400mg Chondroitin Sulphate with added Vitamin C to aid absorption. Together they give added relief from joint pain & osteoarthritis, whilst improving joint mobility & general joint health. It is recommended that 1500mg of glucosamine be taken on a daily basis, to ensure constant supply we recommend a divided dose throughout the day.
