Tablet Presentation

Each film coated tablets contains:
Glucosamine Sulphate         500 mg
Chondroitin Sulphate           400 mg

Glucosamine is made from glucose and glutamine. It is incorporated into glycosaminoglycans (unbranched polysaccharides) which are incorporated into proteoglycans (proteins that contain glycosaminoglycans). Proteoglycans are found in every tissue in the body, primarily in the extracellular matrix, and are remarkable for their ability to attract water.
Chondroitin is one of at least seven glycosaminoglycans and is a primary component of cartilage. Because of its ability to attract water, chondroitin sulfate helps to lubricate the joints.

Mechanism of Action

The mechanism of action of glucosamine or chondroitin is unknown but it is hypothesized that each may inhibit lysosomal enzymes or may stimulate proteoglycan synthesis. The mechanism is different from NSAIDs, which inhibit cyclooxygenase.


Pharmacokinetic studies performed on humans and experimental animals after oral administration of Glucosamine and chondroitin revealed that it can be absorbed orally. Chondroitin shows first-order kinetics up to single doses of 3,000 mg. multiple doses of 800 mg in patients with osteoarthritis do not alter the kinetics of chondroitin. The bioavailability of chondroitin and glucosamine ranges from 15% to 24% of the orally administered dose. Chondroitin and glucosamine is not rapidly absorbed in the gastro-intestinal tract and a high content of labelled chondroitin sulfate is found in the synovial fluid and cartilage.

Side effects

Glucosamine and Chondroitin is LIKELY SAFE for most people. It can cause some mild stomach pain and nausea. Other side effects that have been reported are diarrhea, constipation and swollen eyelids.
