Enjoy Youtheory Collagen 1&3 (1x120TAB). Collagen is our body's key structural protein involved in creating strong and healthy nails, hair, tendons, bones, muscle, and keeping our skin smooth. During our youth collagen helps prevent wrinkles from forming, gives skin elasticity, helps create strong and thicker hair. In our early 20's collagen diminishes by about 1% per year. By the age of 30, the signs of collagen reduction have started to become visible. The reduction in bones and joints begins to be felt. Collagen 1 & 3 are the main collagen types in connective tissue. Collagen Type 2 is a significant part of your body's cartilage with naturally occurring hyaluronic acid for joint cushioning and lubrication. Hyaluronic acid and collagen are vital structural components of the skin. Chondroitin sulfate, also naturally occurring, may provide anti-inflammatory support.
