Glucosamine is an amino sugar that is naturally found in the body, as mentioned by the American Academy of Orthopaedic Surgeons, an organization supported by the National Institutes of Health. Glucosamine stimulates the formation and repair of new joints and cartilages. Glucosamine can also prevent the degeneration of joints and cartilage by protecting them against harmful bodily enzymes. Natural sources like shellfish and other marine animals contain glucosamine, and the preparation of artificial forms of this substance takes place in laboratories. Reduced levels of glucosamine can occur and several causes of this deficiency exist.
Aging
According to the National Institute of Arthritis and Musculoskeletal and Skin Diseases, people age 50 and older are prone to developing injuries in the joints, cartilage and bones. As people age, bone mass and density gradually decreases. The bones lose calcium and other essential minerals, making them thinner. The joints and cartilage become stiff and less flexible. This degenerative process also affects the naturally occurring chemicals found in these key areas. The formation of glucosamine takes place in the fluid surrounding the joints and, with age, the amount of this fluid decreases, causing a deficiency. With less joint fluid, certain parts of the bones and cartilage may rub against each other. The friction caused contributes to bone damage and erosion. The institute further reports that most doctors usually recommend glucosamine supplements to older patients.
Sports Injury
According to Medline Plus, sports injuries and accidents can easily happen during exercise. These injuries are caused by poor training practices and improper use of gear, not warming up sufficiently and unfamiliarity with the equipment. Sports injuries most commonly suffered include sprains, strains, fractures and dislocations. Glucosamine deficiency can happen as a result of sustaining a sports injury. The joint or synovial fluid decreases in amount because of the joint's inflammatory process and structural damage. A decrease in this fluid contributes to less glucosamine production.
Decreased Diet Intake
Glucosamine can be found in marine life such as the shells of shrimp, crab and shellfish. Most people are unable to acquire adequate glucosamine levels from just food intake. Taking glucosamine supplements offers a better method of taking in glucosamine and Mayo Clinic suggests that adults take approximately 1,500 milligrams every day. Not meeting the suggested dosage can result in glucosamine deficiency occurring in individuals.
