Vitamin C Collagen Cofactor
Vitamin C is a collagen cofactor that cross-links fibers—get it from citrus, peppers, and greens paired with protein-rich meals.
Vitamin C acts as a collagen cofactor by hydroxylating proline and lysine so fibers cross-link properly in skin, tendons, and vessels. Citrus, peppers, kiwi, and broccoli provide food-first doses; very low intake can slow wound healing.
Pairing vitamin C–rich produce with protein meals supports synthesis without megadosing.
Common questions
-
Should you take vitamin C with collagen powder?
A produce-rich meal or modest supplement with collagen or protein can support synthesis; megadoses are unnecessary for most healthy eaters.
