Efficacy of Vitamin C Treatment to Aid the Healing of Foot Ulcers in People With Diabetes: A Randomised, Placebo-Controlled Double-Blind Trial: The FOOT-C Study Protocol.
Diabetic foot ulcers are a serious complication of diabetes that can lead to infection and amputation if not properly managed. Standard treatments include wound care, infection control, and offloading pressure, but researchers are exploring additional therapies to speed healing. This article describes the protocol for a randomized, double-blind, placebo-controlled trial that will test whether vitamin C supplements can help heal foot ulcers in people with diabetes. The study plans to enroll 200 participants and follow them for 24 weeks, measuring changes in ulcer size and time to complete healing. The researchers hypothesize that vitamin C, an antioxidant, may reduce ulcer size and improve healing rates compared to a placebo, with fewer side effects. If proven effective, vitamin C could become a simple, low-cost addition to standard DFU care. However, because this is a protocol paper, the results are not yet available, and the true benefits remain uncertain until the trial is completed and published. Patients should not start vitamin C supplements without consulting their doctor, as current evidence is not conclusive.
Key takeaways
- Diabetic foot ulcers are serious and can lead to amputation; effective treatments are urgently needed.
- This is a study protocol for a randomized, double-blind, placebo-controlled trial testing vitamin C in 200 patients.
- The trial will measure ulcer size reduction and time to healing over 24 weeks, comparing vitamin C to placebo.
- If vitamin C works, it could be a cheap and safe way to boost standard DFU care.
- Ask your doctor if vitamin C supplementation is safe and appropriate for your DFU treatment plan.
- Results are not yet available, so discuss with your doctor before starting any new supplements.

Editor's note
For patients in China, this study highlights a potential new avenue for DFU management that is affordable and accessible. However, it is not yet proven, and current specialized DFU centers in China focus on standard care including debridement, infection control, and offloading. Patients should not replace standard care with vitamin C, but may ask their doctor about ongoing research or future availability of this treatment.
