Glucosamine is one of the building blocks of cartilage and occurs naturally in our bodies. It is involved in a number of functions that are vital to supporting good joint health, including maintaining elasticity, strength and lubrication of cartilage in joints.1

People with mild osteoarthritis may benefit from taking clinically trialled daily doses of glucosamine and chondroitin (another component of cartilage) for the relief of joint pain and to assist in slowing cartilage wear.2

How does glucosamine work in the body?

The main function of Glucosamine is to stimulate the production of ‘proteoglycans’. Along with collagen and water, proteoglycans are the main components of cartilage and make up around 10 to 15 per cent of its mass. They consist of chains of proteins with carbohydrates or “sugars” attached to them. Proteoglycans are what allows your cartilage to attract and hold water, which is essential for lubrication and nourishment of your joints. Chondroitin is one of the main proteoglycans produced by the body.3

Should I consider supplementing my glucosamine levels?

Although glucosamine is produced naturally by our bodies, mild osteoarthritis sufferers may benefit from supplementing their body’s reserves with an extra boost. Studies suggest that glucosamine and chondroitin supplementation, when taken consistently, may relieve pain associated with mild osteoarthritis.4

However, it’s important to maintain good joint health throughout adulthood to protect cartilage and minimise the risk of future joint conditions like osteoarthritis. Learn more about natural ways to support your joints here.
