and his body falls apart -- his joints fail, because he can no longer keep the cartilage and tendons strongs, his blood vessels break open, his gums ulcerate and his teeth fall out, his immune system deteriorates, and he dies.
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. Collagen is also required for the repair of blood vessels, bruises, and broken bones. As the most abundant protein in the body, collagen accounts for more mass than all the other proteins put together.
Our body is continually manufacturing collagen to maintain and repair connective tissues lost to daily wear and tear. Without vitamin C, collagen formation is disrupted, resulting in a wide variety of problems throughout the body.
