Collagen is like a special glue that helps hold your body together, making your skin strong and your bones sturdy.
As you grow older, your body makes less of this special glue, so some people take collagen supplements to help.
These supplements might help your skin look younger, your joints feel better, and your hair grow strong.
But remember, it's important to talk to a grown-up before taking any supplements, just like you would with medicine.
