The term ‘glucosamine’ is a blend of two phrases, i.e. glucose and glutamine. The former is a sugar whilst the latter is an amino acid. The two unite to form a compound, which occurs naturally. This compound is accountable for repairing the cartilage between joints and keeping your joints free from pain. Just remember that your bodies produce this compound in a natural way. Yet, at times, the levels are not enough to counteract the effects of age on your joints; as a result, increasing the level of glucosamine in your systems can go a long way towards improving his/her joint health.
