Collagen is the protein that forms connective fibers in tissues such as skin, ligaments, cartilage, bones and teeth. Collagen also acts as a kind of intracellular “glue” that gives support, shape and bulk to blood vessels, bones, and organs such as the heart, kidneys and liver. Collagen fibers keep bones and blood vessels strong, and help to anchor our teeth to our gums. The repair of blood vessels, bruises, and broken bones require the use of collagen. As the most abundant protein in the body, collagen accounts for more mass than all the other proteins put together. But, is collagen something that we should be concerned with having to replenish on a daily basis? Read on to learn why it’s important, and how you can have a leg-up to a little known health crisis that is becoming more common, every day.
