Collagen is the most important protein in the human body, making up 30% of its proteins and found in bones, ligaments, tendons, cartilage and joints, as well as in skin, hair, nails and teeth. Lack of it can cause musculoskeletal system difficulties, skin disorders and both hair and nails to become brittle. 

Starting at age 25, the amount of collagen in the body drops every year and by 35 it is almost completely gone absent. It is therefore advisable to take quality nutritional supplements.

Collagen molecules are too large for the body to absorb in its native form. Enzymatic hydrolysis allows collagen molecules to cleave into short chains the body can directly use to form its own connective tissue. Internal use of collagen is considered to be the most effective because of its excellent absorption and the bioavailability of hydrolyzed collagen lets the body direct it towards where the collagen is needed the most.
