If you are conscientious about the health of your joints, it is likely that you have already heard about glucosamine. Glucosamine is a basic building block for maintaining joint cartilage and the structural integrity of your joints. It also helps promote overall elasticity, flexibility and mobility of the joints. Preliminary studies have found glucosamine to be superior to placebos in promoting joint comfort and improved functionality amongst populations. If you suffer from moderate-to-severe joint pain, consult with your doctor about whether dietary supplementation with glucosamine may be right for you.
