L-hydroxyproline is a non essential amino acid, which means that it is made of other amino acids in the liver; It does not have to be obtained directly through diet. L-hydroxyproline is necessary for the construction of collagen, the main structural protein of human body.
It provides strength for the protein collagen in bones, tendons, cartilage and skin. It is produced with the help of vitamin C by hydroxylation of proline (addition of silicon hydroxide or [OH] group). In vitamin C deficiency, proline cannot be converted to hydroxyproline, so collagen does not have enough strength to maintain skin integrity.
