What is the recommended vitamin C dosage for pressure ulcers at stage 3/4?

• A. 100-200mg/d
• B. 1000-2000ml/d
• C. 60-100mg/dL
• D. 60-100mg/d

Answer: (B)

Pressure ulcers at stage 3/4 require a strong wound-healing response, and vitamin C plays a pivotal role by supporting collagen synthesis and protecting tissues from oxidative stress during repair. Because these wounds have high demands for collagen formation and tissue remodeling, a higher intake of vitamin C is recommended to help accelerate healing. The usual guidance for wound healing in these cases is about 1,000 to 2,000 milligrams per day, typically divided to improve absorption and tolerance. This dosage targets the needs of repaired tissue without relying on lower, general-population amounts. Note that vitamin C is measured in milligrams per day (not milliliters or mg/dL), and very high doses should be used with caution if there are conditions like kidney stones or certain metabolic disorders.
