Collagen is a fibrous protein that contributes to the stability and structure of tissues in the body. In fact, approximately 70% of our skin consists of collagen. If you have too low a level of collagen in your body, you risk seeing a negative change in your skin, nails and hair. The body produces the most collagen until you turn 25, then this production begins to decline. We want to make it easy for you to consume collagen.
