title: Vitamin C: a wound healing perspective.
abstract: Vitamin C, also known as ascorbic acid (AA), is involved in all phases of wound healing. In the inflammatory phase it is required for neutrophil apoptosis and clearance. During the proliferative phase, AA contributes towards synthesis, maturation, secretion and degradation of collagen. Deficiencies affect the maturation phase by altering collagen production and scar formation. The body strives to maintain homeostasis of AA, thereby ensuring availability for collagen synthesis. After wounding, plasma and tissue levels of AA diminish and, as a consequence, supplements may be useful for healing, although levels beyond saturation are excreted Clinicians need to be aware of both the nutritional status of patients with either acute or chronic wounds and the possibility of any AA deficiency which may hinder healing.
