Vitamin C and Tissue Healing: Vitamin C stimulates the process of collagen synthesis. Collagen is a tissue protein that provides tensile strength and elasticity to tissue. During the process of wound healing, this collagen protein accumulates at the site of damaged tissue and subsequently form cross-linking of fibre overwound and speed up the process of healing. The administration of vitamin C at a dose of 500mg to 1.0 gm/day during the post-operative period effectively boost the process of wound healing.
