What are the approximate RDAs for zinc and vitamin C as referenced for wound healing?

• A. Zinc 8-11 mg/day; Vitamin C 75-90 mg/day.
• B. Zinc 20-30 mg/day; Vitamin C 10-20 mg/day
• C. Zinc 2-4 mg/day; Vitamin C 5-10 mg/day
• D. Zinc and Vitamin C have no recommended RDAs

Answer: (A)

Understanding the recommended dietary allowances for nutrients important to wound healing. Zinc supports collagen synthesis, epithelialization, and immune function, all essential for tissue repair, while vitamin C is required for collagen formation and acts as an antioxidant to protect healing tissue. For adults, wound-healing references typically cite about 8–11 mg of zinc per day and about 75–90 mg of vitamin C per day. This pairing matches the amounts commonly advised to support repair processes without exceeding safe intake. The other proposed values either place zinc well outside this range or vitamin C outside the 75–90 mg/day window, which don’t align with the guidance used for wound healing.
