Which vitamin is crucial for the synthesis of collagen?

Vitamin C is essential for the synthesis of collagen, a critical protein that provides structure and support in connective tissues, skin, cartilage, and bones. It plays a vital role in the hydroxylation of proline and lysine residues in collagen, which is necessary for the stability and integrity of the collagen triple helix structure. Without adequate vitamin C, collagen production is impaired, leading to issues such as scurvy, characterized by weakened connective tissues, poor wound healing, and skin problems.

Other vitamins, while important for various bodily functions, do not have the same direct role in collagen synthesis as vitamin C does. For instance, vitamin B12 is primarily involved in red blood cell formation and neurological function, vitamin K is important for blood clotting, and vitamin D helps regulate calcium and phosphorus for bone health.
