What is Collagen?
Collagen is a vital protein produced by the body that is central to the structural aspects of the body.  Collagen forms the structure of much of the body, and has recently found traction within skincare and shampoo products because of its ability to provide your skin and hair with moisture and strength. As you age, the amount of collagen that your body produces decreases, which can cause your skin to become dry and wrinkled and your hair too thin. 
What are the Health Benefits of Collagen?
Collagen is the most abundant protein within the body. Because your body produces less and less collagen as you age, it is important to supplement it into your diet in order to maintain healthy skin, hair, nails, and bones. ,  A 2015 study conducted by the Journal of Medical Nutrition and Nutraceuticals found that women who consumed a beverage mixed with collagen daily for 12 weeks experienced increased skin moisture and a significant decrease in wrinkle depth. Collagen is able to strengthen skin and nails by preventing brittleness. Because it strengthens from their roots, it can also help promote faster growth of hair and nails alike.  Other health benefits which the supplementation of collagen can provide include the prevention of bone atrophy and joint pain relief. Collagen improves bone density and joint strength. Low bone density and weak joints are significant factors linked to fractures and tears within the body. Through this lens, the supplementation of collagen can also help prevent injuries such as fractures or tears.
