The word collagen is derived from Greek, and literally means "glue producer." As the most abundant structural protein found in the human body (about 30% of total protein content) it gives tissues form and strength. Because it is the substance that connects (or "glues") various parts of the body together it is often referred to as "connective tissue." It makes up 70% of the skin, giving it both its strength and elasticity. Collagen is also a major element of the bones, tendons, ligaments, cartilage, and blood vessels.
Avoiding collagen killers like smoking, excessive sun, too much sugar, poor nutrition, stress, and poor hydration is also important! Beginning to preserve collagen early is best. But later is better than never! Changes in diet, exercise, and proper supplementation can all make a big difference.
The effects of age are not inevitable! The wonderful thing is that supporting collagen production helps collagen throughout the body everywhere - inside and out!
