Which vitamin is essential for collagen synthesis?

Vitamin C is essential for collagen synthesis because it plays a critical role as a cofactor in the enzymatic reactions that stabilize and cross-link collagen molecules. Collagen is a primary structural protein found in connective tissues, skin, bones, and cartilage. The presence of vitamin C is necessary for the hydroxylation of proline and lysine residues within the collagen chains, which is vital for the structural integrity and function of collagen fibers.

Without sufficient vitamin C, the body cannot properly synthesize collagen, leading to weakened connective tissue and potential health issues such as scurvy, characterized by symptoms including weakened immunity, joint pain, and skin problems. This highlights the importance of vitamin C not just as a nutrient, but as a crucial player in maintaining skin health and the structural framework of various bodily tissues.
