What is it?
Collagen is the most plentiful protein in your body, forming up to 35% of our whole-body protein content. A major component of connective issues, collagen is found in our bones, skin, muscles, blood vessels, eyes and teeth. The word comes from the Greek word “kólla” meaning glue, as collagen acts as the glue that holds our body together.
Collagen constitutes over 70% of the skin’s dermis and is essential in supporting skin barrier integrity and dermal cellular metabolism–all of which contributes to the skin staying healthy and young. Starting in our twenties our collagen production naturally slows down, declining as much as 30% by the time we hit our 40s. This decrease in collagen causes dermis structure and support for the epidermis to deteriorate, leading to skin textures, wrinkles, fine lines, and dryness.
The good news is, ingested collagen’s positive impact on skin has been extensively studied and well documented.
What are the benefits?
