Glucosamine Pure by ESC Laboratoire is a molecule present naturally in the body and especially in cartilage. It is synthesized in the body from glucose, fructose and glutamine, an amino acid. Glucosamine slows down the deterioration of the cartilage in all joints and promotes the lubricating action of synovial fluid, the natural lubricant of joints which helps them function. This molecule also reduces the destruction of certain cartilage molecules and improves the vascularization of the bone, which provides better flexibility under the cartilage. When the glucosamine production process goes wrong, cartilage deteriorates and inflammatory phenomena such as arthritis and osteoarthritis can develop. Glucosamine levels decrease with age, so it is advisable to have an additional intake to ensure flexibility and elasticity. The care product glucosamine is mainly known for soothing pain related to joint disorders. It nevertheless has a preventive action and has no regenerative effect in the event of advanced problems.
