The role of protein in wound healing has been documented in many studies with the focus on offering high calorie, high protein supplements in addition to diet. Protein is responsible for cell multiplication, repair, and synthesis of enzymes involved in wound healing. Protein supplies the binding material of skin, cartilage, and muscle. In wound cases, research supports offering protein above the traditional 0.8 grams/kilogram of body weight recommended for the healthy adult.

Metabolic Roles of Vitamin C

The major function of vitamin C (ascorbic acid) in wound healing is assisting in the formation of collagen, the most important protein of connective tissue. Vitamin C, a water-soluble vitamin found in water-filled foods, dissolves in water and is transported in the bloodstream. Excess amounts are excreted in the urine; however, since the body does not store vitamin C, food sources should be consumed on a regular basis. Vitamin C supplementation has been shown to increase tensile strength and collagen synthesis by assisting in the hydroxylation of lysine and proline, major constituents of collagen.
