What vitamin is essential for the synthesis of collagen?

Vitamin C is essential for the synthesis of collagen, which is a crucial protein that provides structure to various tissues such as skin, tendons, ligaments, and blood vessels. Collagen synthesis involves hydroxylation of proline and lysine amino acids in the collagen molecule, and this process requires Vitamin C as a cofactor. Without adequate Vitamin C, the body cannot effectively produce collagen, leading to connective tissue disorders, such as scurvy, characterized by symptoms like weakened blood vessels, gum disease, and compromised wound healing.

Other vitamins mentioned, while important for various bodily functions, are not directly involved in collagen synthesis. Vitamin E is primarily known for its antioxidant properties, Vitamin K is critical for blood clotting processes, and Vitamin A plays a key role in vision and immune function. However, none of these vitamins facilitates the structural formation of collagen as Vitamin C does.
