The nutrients most tied to making stable collagen and supporting tissue repair are Vitamin C and Zinc. Vitamin C is essential for collagen formation because it serves as a cofactor for the enzymes that hydroxylate proline and lysine residues in procollagen. This hydroxylation is necessary for the collagen molecules to form the strong triple-helix structure and for cross-linking that gives strength to the repaired tissue. Without enough Vitamin C, collagen fibers are weak and wound healing is impaired, a situation seen in scurvy.

Zinc plays several key roles in wound healing. It supports DNA synthesis and cell division, which fibroblasts need to proliferate and lay down new collagen. It also acts as a cofactor for enzymes involved in collagen synthesis and remodeling, and it helps regulate immune function and epithelialization—both important in the healing process. A zinc deficiency similarly impairs wound healing and collagen formation.

While the other nutrients listed have important health roles, they don’t directly drive collagen synthesis and wound repair to the same extent. Vitamin D and Vitamin A influence immune responses and epithelialization, Vitamin E acts mainly as an antioxidant, and Magnesium is a general cofactor for many reactions but is not as specifically linked to collagen synthesis and wound healing as Vitamin C and Zinc.
