Youtheory Collagen Plus Biotin, 390 Tablets

Collagen is the most abundant protein in the human body and a key constituent of skin, joints, bones, blood vessels, organs and more. The word “collagen" is derived from kolla, the Greek word for glue. Collagen is literally the substance that binds us together. It forms an extensive netlike framework throughout the inner body and imparts shape and structural strength to virtually every tissue. While bountiful in youth, the collagen content of the body gradually decreases with age, leading to thinner, weaker, less resilient tissues over time.Loss of collagen is one of the most profound consequences of the aging process.

Vitamin C is well-known for its antioxidant properties.^* But the beauty of Vitamin C is that it's also critical for internal collagen synthesis.^* Vitamin C is used by the body to convert proline into hydroxyproline – an amino acid that plays a key role in collagen stability; in short, hydroxyproline puts a twist in collagen's triple helix structure. Without this singular amino acid, collagen-containing tissues will inevitably fall apart and the body will cease to manufacture new collagen proteins.
