Glucosamine is a naturally occurring substance in the body that plays an important role in the formation and maintenance of healthy joint tissue. It is a type of sugar molecule that is a building block for the proteins and other substances that make up cartilage.
An analogy for glucosamine might be that it is like the bricks that are used to build a house. Just as bricks are essential for constructing a sturdy and durable house, glucosamine is essential for building and maintaining healthy joints. Without enough glucosamine, the body may not be able to produce enough of the substances needed to repair damaged joint tissue or maintain the integrity of healthy joint tissue over time.
