Collagen is a major structural protein in the human body (found in skin, joints, bones, blood vessels and connective tissues). As we age, collagen naturally breaks down and diminishes over time - leading to the early signs of aging. Youtheory® Collagen Advanced Formula with added Vitamin C is designed to help replenish the body’s supply of this vital protein.* This product delivers intensive nourishment to help counteract the effects of the aging process.Youtheory Collagen Enhanced Formula Type 1 and 3 contains 18 amino acids. 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.
