Could an inexpensive vitamin already found in most kitchens help save the lives of people with severe injuries?
According to a new scientific review, the answer may be yes, although researchers say much more evidence is still needed before hospitals change their treatment guidelines.
The review, published in BMJ Military Health, examined studies of high-dose vitamin C given through an intravenous drip, also known as an IV. Unlike vitamin tablets, IV treatment delivers the nutrient directly into the bloodstream, allowing much higher levels to reach the body quickly.
People who experience major trauma often develop a dangerous chain of events inside the body. Severe injuries can cause inflammation, damage blood vessels, weaken the immune system, and increase the risk of life-threatening infections such as sepsis. Multiple organs may begin to fail, requiring intensive care treatment.
Vitamin C may help because it is involved in many important biological processes. It supports collagen production for wound healing, protects cells from oxidative damage, improves blood vessel function, and helps the body respond to severe stress.
During critical illness, vitamin C stores are rapidly used up, leading scientists to investigate whether replacing large amounts could improve recovery.
The researchers searched medical databases and identified six suitable studies involving 5,171 trauma patients. Although the studies differed in design, many pointed in the same direction.
Patients who received high-dose IV vitamin C generally had lower death rates, fewer cases of sepsis, shorter stays in intensive care units, and shorter overall hospital stays. Some studies also suggested a lower risk of multiple organ failure.
However, the researchers urged caution. Half of the available studies were observational rather than randomized clinical trials, which are considered the strongest form of medical evidence.
The studies also differed in vitamin C doses, treatment schedules, and the additional therapies patients received. Because vitamin C was never given as the only treatment, it is impossible to know exactly how much it contributed to the improved outcomes.
Another unanswered question is timing. None of the studies determined when vitamin C should be started after injury, leaving doctors without clear guidance on the best treatment protocol.
The findings are promising because vitamin C is inexpensive, widely available, and has a well-understood safety profile when used appropriately in hospitals.
If future clinical trials confirm these benefits, it could become an important addition to trauma care, particularly in military medicine and emergency settings. For now, the evidence suggests potential rather than proof, and larger randomized trials are essential before routine use can be recommended.
