According to The Cleveland Clinic, collagen is a protein that's all over your body—in your muscles, bones, tendons, ligaments, organs, blood vessels, skin, intestinal lining, and other connective tissue. Your body

makes collagen, but the production can decrease when you get older, which can lead to wrinkles and crêpey skin, stiffer joints, shrinking muscles, joint pain, and gastrointestinal problems. And the Clinic has said that collagen is also a strength-building hair protein. Though, more research needs to be done on the definitive effects of collagen on hair growth and health.

To support the formation of collagen in the body, the Mayo Clinic says it's important to consume enough foods that contain vitamin C, zinc, copper, and manganese plus plenty of fruits, vegetables, nuts, and seeds. And you'll want to avoid excess sugar intake, smoking, sun or UV exposure, and environmental pollutants—all of which can disturb collagen production.
